Adherence to Disease Modifying Drugs among Patients with Multiple Sclerosis in Germany: A Retrospective Cohort Study

Adherence, Persistence, Switching and Costs of Injectable and Oral Therapies for Multiple Sclerosis. Real Life Analysis Over 6 Years of Treatment

Background: Adherence and persistence to treatment with disease-modifying therapies (DMTs) is a predictor of the efficacy of treatment. Aims: The objectives of the study were the analysis of adherence, persistence, switches, and costs of the drugs used in MS. Methods: This is a retrospective non-interventional pharmacological observational study of 610 patients diagnosed with Relapsing-Remitting Multiple Sclerosis (RRMS) under therapy between January 2007 and September 2022. Results: Adherence values were greater than 0.75 for all the drugs in considered for the study. The mean persistence value was 2.5 years on the analysis performed on the first-line treatment. Conclusion: In a therapy in which adherence is predominant, but not exclusive to therapy efficacy, persistence to the drug is synonymous with drug efficacy.

Treatment satisfaction with disease-modifying therapy is the only predictor of Adherence among multiple sclerosis patients from Upper Egypt

Despite the proven efficacy of the disease-modifying therapy (DMT) for multiple sclerosis (MS), the rates of non-adherence are frequently high. We aimed to evaluate the rate of non-adherence to the first DMT in Upper Egypt and identify different contributing factors. Out of 310 patients, ninety-seven adult patients with RRMS were recruited from three MS units located in Upper Egypt and were subjected to the following: complete clinical history, expanded disability status score (EDSS), Eight-item Morisky Medication Adherence Scale (MMAS-8), abbreviated Treatment Satisfaction Questionnaire for Medication-9 (TSQM-9), Hamilton depression scale, Fatigue Severity Scale (FSS) and the Pittsburgh Sleep Quality Index (PSQI). According to MMAS-8 scores, 63 (64.9%) of patients were non-adherent to their first DMT. Non-adherent patients are more likely to have longer disease duration (p = 0.002), longer duration on first DMT (p = 0.030), first DMT-start date before 2019 (p = 0.040), and lower treatment satisfaction scores (p = 0.016). However, there was no significant relation with physical disability, depression, fatigue, or sleep quality. On the regression analysis model, a lower treatment satisfaction score was the only predictor of DMT non-adherence (p = 0.012). Despite expanding DMT options, non-adherence among MS patients in Upper Egypt is high. Treatment satisfaction with DMT is the only predictor of adherence among MS patients of Upper Egypt. Adherence and satisfaction with the prescribed DMT should be assessed carefully to maximize DMT benefits.

Preferences, Adherence, and Satisfaction: Three Years of Treatment Experiences of People with Multiple Sclerosis

Background

To reduce the risk of long-term disability in people with Multiple Sclerosis (pwMS), an increasing number of disease-modifying immune therapies (DMT) are available, involving diverse mechanisms of action, levels of efficacy, treatment risks, and tolerability aspects. Including patient preferences and expectations in shared decision-making may improve treatment satisfaction, adherence, and persistence.

Purpose

To investigate long-term alignment of individual preferences and expectations of pwMS with their actual DMT and its effect on treatment satisfaction, health-related quality of life (HRQoL), adherence, and treatment discontinuation.

Methods

A total of 401 pwMS beginning a new DMT were enrolled from 2015 to 2018 in a non-interventional study at three German MS centres. Patient preferences regarding DMT, TSQM-9, SF36, and self-reported adherence as well as relapses and EDSS were recorded at baseline and every 3 to 6 months for up to 3 years.

Results

Efficacy and tolerability were the highest-ranking preferences at baseline. Actual selection of DMT corresponded more closely to safety than efficacy, tolerability, or convenience preferences. Participants reported excellent adherence throughout the study. DMT persistence was 69.0%, with earlier discontinuation for injectable vs oral or infusion therapies. Breakthrough disease, rather than patient-reported outcomes, was the main driver of DMT discontinuation. For all routes of administration, global treatment satisfaction increased over time despite lower satisfaction with convenience. Several patterns of changing preferences were observed.

Conclusion

This study provides insight into the interaction of DMT preferences of pwMS with their actual treatment experience. Treatment decisions should be aligned with long-term expectations of pwMS to promote continuous adherence.

Beliefs about Medicines and the Level of Intentional Non-Adherence to Treatment among Patients with Multiple Sclerosis Treated with First-Line Drugs

INTRODUCTION

Multiple sclerosis (MS) is a chronic inflammatory, demyelinating and neurodegenerative disease of the central nervous system. MS has no curable disease but drug modifying therapy (DMT) can delay the long-term disability progression of the disease. The effectiveness of MS treatment depends on the patient's adherence to therapy.

AIM

This study evaluated the level of intentional non-adherence and the relationship between beliefs about medication and the level of intentional non-adherence to treatment of patients with multiple sclerosis.

MATERIAL AND METHODS

A group of 146 patients with relapsing-remitting MS were included. To assess different aspect of adherence, the Intentional Non-Adherence Scale (INAS) was used. For evaluating patients' beliefs and opinions regarding medication, the Beliefs about Medicines Questionnaire (BMQ) was used.

RESULTS

The mean total INAS score was 51.41 ± 27.83 points. Patients were most concerned about the necessity to take medication and least concerned about the harm caused by medication. The overuse and harm domains of the BMQ were significantly correlated with INAS scores (p < 0.05).

CONCLUSIONS

Independent determinant of intentional non-adherence was overuse.

The Adherence and Outcomes Benefits of Using a Connected, Reusable Auto-Injector for Self-Injecting Biologics: A Narrative Review

Many biologics are now self-administered by patients at home. A variety of self-injection devices are available, including vials and syringes, prefilled syringes, and spring-driven prefilled pens or auto-injectors. Each has advantages and drawbacks, and different devices suit different patients. For example, some patients have difficulty achieving consistent and successful self-injection due to poor manual dexterity, or experience anxiety at the prospect of self-injection or injection-site pain. These factors can reduce patients' medication adherence and overall experience. Furthermore, while self-injection brings patients many benefits, the proliferation of single-use injection devices has implications for environmental sustainability, including the reliance on single-use plastics, repeated freighting requirements, and need for incineration as hazardous waste. Recently developed, innovative electromechanical auto-injector devices offer technological enhancements over existing devices to overcome some of these issues. Features include customisable injection speeds or durations, consistent rate of injection, electronic injection logs and reminders, and step-by-step, real-time instructions. Indeed, a growing body of evidence points to higher adherence rates among patients using electromechanical devices compared with other devices. Further, with time, the reusability of electromechanical devices may prove to lighten the environmental impact compared with disposable devices, especially as research continues to optimise their sustainability, driven by increased consumer demands for environmental responsibility. This narrative review discusses the differences between prefilled syringes, spring-driven prefilled pens, and electromechanical devices. It also explores how these features may help reduce injection-associated pain and anxiety, improve patient experience, connectivity and adherence, and drive sustainability of biologic drugs in future.

Using an Intervention Mapping Approach to Improve Adherence to Disease-Modifying Treatment in Multiple Sclerosis

BACKGROUND

Up to 50% of individuals with multiple sclerosis (MS) who are prescribed disease-modifying treatments (DMTs) do not take them as advised. Although many studies report on DMT adherence rate, few studies report on interventions involving individuals with MS. The current paper describes the development of an intervention aimed at improving adherence to DMTs among identified nonadherent individuals with MS.

METHODS

An intervention was developed using an Intervention Mapping approach, recommendations from reviews on medication adherence, and input from individuals with MS. Its content was determined by theories of health behavior (specifically, a perceptions and practicalities approach), empirical evidence collected among the specific target population (an observational "needs assessment" stage [n = 186]), and other studies.

RESULTS

A personalized intervention was tailored to the reasons for nonadherence, uncovered during the observational needs assessment stage, to be delivered sequentially by a neurologist and a psychologist. After the intervention objectives were identified, components of the intervention were set: psychoeducation and ways of coping with adverse effects; modification of unhelpful treatment beliefs (such modifications were found predictive of adherence in the observational phase of the study); improving confidence and self-efficacy; and developing strategies for remembering to take DMTs. These components were embedded within motivational interviewing.

CONCLUSIONS

Intervention Mapping was useful in developing an intervention grounded both in the theoretical approach of perceptions and practicalities and in empirical evidence from the literature and the target sample; concurrently, identifying determinants that the intervention did not address. The effectiveness of the intervention-which could potentially improve adherence among individuals with MS-needs to be examined.

Real-life outcomes for oral disease-modifying treatments of relapsing-remitting multiple sclerosis patients: Adherence and adverse event profiles from Marmara University

BACKGROUND

Disease-modifying treatments (DMT) are used to prevent future relapses and disability. High long-term adherence to treatment is important to achieve disease control. This study aims to investigate and compare adherence, adverse event (AE) profiles, and frequencies, main reasons for treatment discontinuation under Teriflunomide (TERI), Dimethyl Fumarate (DMF), and Fingolimod (FNG) for relapsing-remitting MS (RRMS) patients. This study is designed to explore patient-reported experiences in real-life settings.

METHODS

Patients who were older than 18 years with a definite diagnosis of RRMS and no history of stem-cell transplantation were included. Outpatient clinic data files at the Neurology Department of Marmara University from June 2012 to June 2019 were examined retrospectively.

RESULTS

One hundred and ninety MS patients were enrolled. 118 FNG, 51 DMF, 44 TERI treatment cycles were recorded. Time sincedisease onset, time since diagnosis, and treatment duration were significantly longer for FNG (p = 0.012, p = 0.004, p < 0.001). 72.8% of all the treatment cycles were continued. There was no significant difference in treatment continuity between the 3 DMT groups. The most common reasons for treatment discontinuation in order of frequency were adverse events, the progression of the disease, and the persistence of relapses. No significant difference was found for treatment discontinuation reasons. 32% of the patients reported at least one AE. 28% FNG, 49 % DMF, and 27.3% TERI using patients reported AEs. AEs were much more frequently reported for DMF (p = 0.015). The most common adverse events for each DMT were alopecia (n = 6, 13.6%) for TERI, flushing for DMF (n = 20, 39.2%), and persistent lymphopenia for FNG (n = 9, 7.6%). No severe or life-threatening AE was reported for DMF, one patient experienced pancreatitis under TERI, and 11 (9.3%) patients using FNG had to stop treatment due to serious or life-threatening AEs including cardiac adverse events, opportunistic infections, and dysplasia.

DISCUSSION

Overall treatment discontinuation because of AEs is as low as 10.3% in this study. However, AEs are still the main reason for treatment drop-out.

Effect of an educational intervention based on the theory of planned behavior on improving medication adherence in patients with multiple sclerosis treated with injectable disease-modifying drugs: randomized controlled trial

BACKGROUND

Adherence to prescribed treatment in chronic diseases, as occurs in multiple sclerosis (MS), is a critical factor for a successful therapeutic response. This study aimed to investigate the effect of educational program based on Theory of Planned Behavior (TPB) on treatment adherence in patients with multiple sclerosis (MS) receiving injectable immunomodulatory drugs.

METHODS

The present study is an educational randomized controlled trial research that was conducted on 100 patients with MS who had gone to MS clinic in Tehran city (Iran). The samples were randomly assigned to the intervention (N = 50) and control groups (N = 50). Data collection instrument was a researcher-made questionnaire based on TPB. Then, educational program was performed for the intervention group through four educational sessions. After three months, data collection was repeated for the two groups and data were analyzed.

RESULTS

The knowledge and performance of the intervention group on treatment adherence drugs increased from 56.25 ± 20.3 to 78.31 ± 15.57 and 56.22 ± 5.76 to 71.62 ± 12.01 after the education respectively (p < 0.001). The mean of construct of TPB in the intervention group also increased after the intervention (p < 0.05).

CONCLUSION

Applying the TPB model proved is very effective in developing an educational program for patients with MS, to enhance treatment adherence drugs. Besides such programs, follow-up education for controlling and monitoring are highly recommended.

TRIAL REGISTRATION

The Quality of Life and Medication Adherence in Patients with Multiple Sclerosis-Cross-Sectional Study

Multiple sclerosis (MS) is a chronic, degenerative autoimmune inflammatory disease of the central nervous system. MS is characterized by a wide range of symptoms and unpredictable prognosis, which can severely affect patient quality of life (QOL). The treatment strategy includes acute relapse treatment, disease-modifying treatment (DMT), and symptomatic therapy. Adherence to long-term DMTs is essential in order to maximize the therapeutic effects for MS and is crucial to health-related quality of life (HRQOL). This study aimed to evaluate the relationship between QOL and adherence to DMTs in MS patients. A group of 344 patients (73% females) aged 39.1 years with relapsing-reemitting MS were included. The Multiple Sclerosis International Quality of Life (MusiQOL) and the Multiple Sclerosis Treatment Adherence Questionnaire (MS-TAQ) were used. An injection of interferon (IFN)-β1b was used in 107 patients, IFN-β1a in 94 patients, and glatiramer acetate in 34 patients. The oral treatment includes teriflunomide in 14 patients, dimethyl fumarate in 86 patients, and fingolimod in nine patients. No statistically significant differences (p > 0.05) were observed in adherent (ADH) vs. non-adherent patients (non-ADH) in MusiQOL. The total adherence rate was 72% (MS-TAQ). An analysis of the univariate logistic regression model showed an effect of only the activities of daily living (ADL) and relationship with the healthcare system (RHCS) domains on the level of adherence to treatment recommendations. The other variables studied do not affect the level of adherence. Higher QOL levels in the ADL and RHCS domains affect medication adherence in MS patients. Our findings could help manage MS patients, promoting interventions on ADLs and good relationships with healthcare providers to improve their adherence to therapy and result in better QOL.

Immunotherapy for people with clinically isolated syndrome or relapsing-remitting multiple sclerosis: treatment response by demographic, clinical, and biomarker subgroups (PROMISE)-a systematic review protocol

BACKGROUND

Multiple sclerosis (MS) is an inflammatory and degenerative disease of the central nervous system with an increasing worldwide prevalence. Since 1993, more than 15 disease-modifying immunotherapies (DMTs) have been licenced and have shown moderate efficacy in clinical trials. Based on the heterogeneity of the disease and the partial effectiveness of therapies, a personalised medicine approach would be valuable taking individual prognosis and suitability of a chosen therapy into account to gain the best possible treatment effect. The primary objective of this review is to assess the differential treatment effects of all approved DMTs in subgroups of adults with clinically isolated syndrome or relapsing forms of MS. We will analyse possible treatment effect modifiers (TEM) defined by baseline demographic characteristics (gender, age), and diagnostic (i.e. MRI measures) and clinical (i.e. relapses, disability level) measures of MS disease activity.

METHODS

We will include all published and accessible unpublished primary and secondary analyses of randomised controlled trials (RCTs) with a follow-up of at least 12 months investigating the efficacy of at least one approved DMT, with placebo or other approved DMTs as control intervention(s) in subgroups of trial participants. As the primary outcome, we will address disability as defined by the Expanded Disability Status Scale or multiple sclerosis functional composite scores followed by relapse frequency, quality of life measures, and side effects. MRI data will be analysed as secondary outcomes. MEDLINE, EMBASE, CINAHL, LILACS, CENTRAL and major trial registers will be searched for suitable studies. Titles and abstracts and full texts will be screened by two persons independently using Covidence. The risk of bias will be analysed based on the Cochrane "Risk of Bias 2" tool, and the certainty of evidence will be assessed using GRADE. Treatment effects will be reported as rate ratio or odds ratio. Primary analyses will follow the intention-to-treat principle. Meta-analyses will be carried out using random-effects models.

DISCUSSION

Given that individual patient data from clinical studies are often not available, the review will allow to analyse the evidence on TEM in MS immunotherapy and thus support clinical decision making in individual cases.

Ascertaining Medication Use and Patient-Reported Outcomes via an App and Exploring Gamification in Patients With Multiple Sclerosis Treated With Interferon β-1b: Observational Study

BACKGROUND

The BETACONNECT autoinjector and myBETAapp app were designed to support patients with multiple sclerosis receiving interferon β-1b and are an ideal platform for digital observational studies. A recent pilot study in Germany demonstrated the feasibility of using the app to recruit patients, obtain informed consent, and evaluate medication-taking behavior over 6 months.

OBJECTIVE

This study aims to describe medication-taking behavior for 1 year in patients with multiple sclerosis receiving interferon β-1b based on data collected from the app and to provide information on patient-reported outcomes (PROs). The optional use of the cognitive training tool PEAK (Peak, formerly Brainbow Ltd) is included to test the feasibility of gamification in this setting.

METHODS

A prospective and retrospective, exploratory, digital, observational cohort study was conducted among users of the app in Germany. Invitations to participate were sent to patients' apps between February and May 2019. Participants provided electronic informed consent. Injection-related data from consenting patients' devices were collected prospectively for 1 year following the consent date and retrospectively for ≤1 year from the first day of use (if historical data were available). Participants also completed three electronic PRO instruments every 3 months: the EuroQol 5-Dimension, 5-Level questionnaire (EQ-5D-5L); the Treatment Satisfaction Questionnaire for Medication (TSQM; version II); and a questionnaire on satisfaction with treatment support (on a server accessed via an emailed hyperlink). All patients were offered optional access to the professional version of PEAK.

RESULTS

Of 1778 registered app accounts (May 2019), 79 patients (4.44%) provided informed consent; 62 (3.49%) were eligible for inclusion in the prospective analysis, of whom, 60 (97%) also had retrospective data. The mean age of the 62 participants was 43.2 (SD 11.5) years and 41 (66%) were women. Compliance over the 1-year prospective observational period (primary end point) was high (median 98.9%, IQR 94.3%-100%) and similar among men and women. Persistence and adherence (coprimary end points) decreased from 85% (53/62) and 74% (46/62), respectively, at 6 months to 76% (47/62) and 65% (40/62), respectively, at 12 months; both were higher in men than in women. A retrospective analysis showed similar patterns. The PRO questionnaires were answered by 79% (49/62) of the participants at baseline and 50% (31/62) of them at month 12. Women had more severe problems in some EQ-5D-5L dimensions (mobility, usual activities, and pain/discomfort) and lower median convenience scores on the TSQM (version II) than men. At month 12, 84% (26/31) of the patients were satisfied or very satisfied with the app. PEAK was used by 67% (14/21) of men and 49% (20/41) of women.

CONCLUSIONS

This study showed high compliance and decreasing persistence and adherence over 1 year and demonstrated the feasibility of including remotely completed electronic PRO instruments in digital observational studies.

Long-Term Effectiveness, Safety and Tolerability of Fingolimod in Patients with Multiple Sclerosis in Real-World Treatment Settings in France: The VIRGILE Study

Introduction

It is important to confirm the effectiveness and tolerability of disease-modifying treatments for relapsing–remitting multiple sclerosis (RRMS) in real-world treatment settings. This prospective observational cohort study (VIRGILE) was performed at the request of the French health authorities. The primary objective was to evaluate the effectiveness of fingolimod 0.5 mg in reducing the annualised relapse rate (ARR) in patients with RRMS.

Methods

Participating neurologists enrolled all adult patients with RRMS starting fingolimod treatment between 2014 and 2016, who were followed for 3 years. Follow-up consultations took place at the investigator’s discretion. The primary outcome measure was the change in ARR at month 24 after fingolimod initiation. Relapses and adverse events were documented at each consultation; disability assessment (EDSS) and magnetic resonance imagery were performed at the investigator’s discretion.

Results

Of 1055 eligible patients, 633 patients were assessable at month 36; 405 (64.0%) were treated continuously with fingolimod for 3 years. The ARR decreased from 0.92 ± 0.92 at inclusion to 0.31 ± 0.51 at month 24, a significant reduction of 0.58 [95% CI − 0.51 to − 0.65] relapses/year (p < 0.001). Since starting fingolimod, 461 patients (60.9%) remained relapse-free at month 24 and 366 patients (55.5%) at month 36. In multivariate analysis, no previous disease-modifying treatment, number of relapses in the previous year and lower EDSS score at inclusion were associated with a greater on-treatment reduction in ARR. The mean EDSS score remained stable over the course of the study. Sixty-one out of 289 (21.1%) patients presented new radiological signs of disease activity. Treatment-related serious adverse events were lymphopenia (N = 21), bradycardia (N = 19), elevated transaminases (N = 9) and macular oedema (N = 9).

Conclusions

The effectiveness and tolerability of fingolimod in everyday clinical practice are consistent with findings of previous phase III studies. Our study highlights the utility of fingolimod for the long-term management of patients with multiple sclerosis.

Safety and Efficacy of Fingolimod in Iranian Patients with Relapsing-remitting Multiple Sclerosis

Introduction:

Fingolimod is the first confirmed oral immune-modulator to treat Relapsing-Remitting Multiple Sclerosis (RRMS). This study aimed to investigate the safety and efficacy of fingolimod therapy in Iranian patients with RRMS.

Methods:

In our trial, 50 patients resistant to conventional interferon therapy were assigned to receive fingolimod 0.5 mg per day for 12 months. The number of Dadolinium (Gd)-enhanced lesions, enlarged T2 lesions, and relapses over 12 months were considered as endpoints and compared to baseline. Liver biochemical evaluations and lymphocyte count were done at baseline and in months 3, 6, and 12 of the study. Patients were also monitored for possible cardiovascular events within the first 24 h and other side effects routinely.

Results:

Among the patients who completed the trial, the number of Gd-enhanced and enlarged T2 lesions over 12 months significantly decreased (P=0.03 and P<0.001, respectively). The proportion of relapse-free patients was higher compared to the onset of fingolimod administration. There were no significant alterations in the Expanded Disability Status Scale (EDSS) scores. A slight, transient increase was recorded in liver enzymes among the participants. Lymphocyte count reduced by 61% at month 1 and displayed a gradual increase until month 12. No bradycardia and macular edema were recorded.

Conclusion:

These findings indicate an effective first-line fingolimod therapy for the first time in Iranian patients with RRMS. The decrease in the number of new attacks and the amelioration of MRI lesions were the benefits of fingolimod therapy, suggesting that it is preferred to other medicines to treat RRMS in Iran.

Patients experiences with multiple sclerosis disease-modifying therapies in daily life - a qualitative interview study

Background

Besides coping with a disease with many uncertainties, people with relapsing-remitting multiple sclerosis face complex decisions concerning disease-modifying therapies (DMTs). In an interview study, we aimed to assess patients’ experiences with DMTs.

Methods

Problem-centred interviews were conducted with 50 people with relapsing-remitting multiple sclerosis in Germany using maximum variation sampling and covering all licensed DMTs. Data were analysed thematically using deductive and inductive categories.

Results

47 of 50 patients had treatment with at least one of the approved DMTs. The main themes were: (1) starting a DMT, (2) switching to another DMT, (3) discontinuing a DMT, and (4) multiple sclerosis without starting a DMT. Different intercorrelated factors influenced the decision-making processes for or against a DMT. Individual experiences with DMTs in daily life contained the effort in administration, success, and failure of DMTs, coping strategies and well-being without DMTs. The decision-making process for or against a DMT and the use of those treatments can be understood as a constant, continually shifting process, complicated by different factors, which change over time. Experiences with DMTs were characterized by attempts to handle uncertainty and to (re)gain control and integrate adaptivity into one’s life.

Conclusions

The study provides a rich and nuanced amount of patients’ experiences with DMTs. The findings demonstrate the importance for practitioners to look at current life circumstances of patients with multiple sclerosis when recommending a DMT and to promote and enable patients to make informed decisions.

Predictors of adherence and persistence to disease-modifying therapies in Multiple Sclerosis

BACKGROUND AND AIMS

In multiple sclerosis (MS), non-adherence/non-persistence is related to suboptimal response to treatment, including disease relapses and the need for more expensive healthcare. The aim of this study was to identify predictors related to adherence to disease modifying therapies (DMTs) in a cohort of Argentinian MS patients.

METHODS

We conducted a cross-sectional study at the National Medical Care Program from Argentina. MS patients with at least one claim for a DMT from 1 January 2017 to 1 October 2017 were identified. A telephone survey was performed to assess clinical and demographic factors. The medication possession ratio (MPR) was used to estimate adherence; MPR <80% defined non-adherence. Associations were studied using a logistic regression model.

RESULTS

Our database included 648 MS patients. A total of 360 patients (60% females, mean age 55.3 years) accepted to participate. Of these, 308 (85.5%) patients were receiving DMT at the time of the survey. Some 198 (63.7%) were receiving injectable therapies. Optimal adherence was 47.7%. Adherence was associated with oral medication [odds ratio (OR) 1.83 95% confidence interval (CI) 1.13-3.00, p = 0.014]. A factor related to oral drugs was higher educational level (OR 2.86 95%CI 1.41-5.81, p = 0.004).

CONCLUSION

This real-world study showed better adherence and persistence on treatment with oral therapies in MS patients in Argentina.

Real-World Assessment of Interferon-β-1b and Interferon-β-1a Adherence Before and After the Introduction of the BETACONNECT® Autoinjector: A Retrospective Cohort Study

BACKGROUND

Both interferon beta-1b (IFN-β-1b) and interferon beta-1a (IFN-β-1a) are immunomodulators that require regular subcutaneous self-administration by patients with multiple sclerosis (MS). However, no electronic autoinjector is available for IFN-β-1a in the US.

OBJECTIVE

This retrospective cohort study investigated adherence to two subcutaneous disease-modifying therapies, IFN-β-1b and IFN-β-1a, during two periods (before and after the introduction of the BETACONNECT® autoinjector for IFN-β-1b).

PATIENTS AND METHODS

Data were evaluated from the MarketScan database for adults in the US with an MS diagnosis and a medical claim for subcutaneous IFN-β-1b or IFN-β-1a, either before (October 2013-September 2015) or after the introduction of BETACONNECT (October 2016-September 2018). Patient populations were propensity-score matched by demographic and clinical characteristics. Persistence was recorded, and adherence was evaluated by medication possession ratio (MPR).

RESULTS

The study included 196 IFN-β-1b and 365 IFN-β-1a people with MS (PwMS) (pre-BETACONNECT period), and 126 IFN-β-1b and 223 IFN-β-1a PwMS (post-BETACONNECT period). In the pre-BETACONNECT period, the proportion with at least 80% MPR was higher for IFN-β-1a (90%) than for IFN-β-1b (83%), but in the post-BETACONNECT period the proportion with ≥ 80% MPR was higher for IFN-β-1b (92%) than for IFN-β-1a (86%). In the pre-BETACONNECT period, median persistence (in days) was higher for IFN-β-1a (199) than for IFN-β-1b (152), while in post-BETACONNECT period persistence was higher for IFN-β-1b (327) than for IFN-β-1a (229).

CONCLUSIONS

Following the introduction of BETACONNECT, this exploratory study suggested that PwMS taking IFN-β-1b were more adherent compared with those taking IFN-β-1a, with higher persistence, and more than 90% reached 80% MPR, a threshold commonly used to define good adherence.

Objective medication adherence and persistence in people with multiple sclerosis: a systematic review, meta-analysis, and meta-regression

BACKGROUND: Medication adherence is critical for the realization of pharmacotherapy benefits and reduced healthcare expenditure. Studies have shown up to 60% of people with Multiple sclerosis (MS) experience suboptimal medication adherence, which is associated with poorer health outcomes and subsequent discontinuation. The current systematic review reported on objectively measured adherence and discontinuation rates for self-administered oral and injectable disease-modifying therapies (DMTs). OBJECTIVES: To identify whether, in people with MS, the introduction of oral DMTs has improved medication adherence when compared with injectable DMTs. The secondary aim was to report synthesized objectively measured medication adherence and persistence rates for both oral and injectable DMTs in MS across varying study durations. METHODS: Literature searches were conducted through PubMed, Web of Science, Scopus, and PsycINFO. Inclusion criteria were limited to English, peer-reviewed, objective, self-administered DMT articles, published between July 1993 to December 2019. Publications reporting combined intravenous and self-administered DMT data, or that did not account for DMT switching in discontinuation rates, were excluded. Data were synthesized into observation lengths ranging from less than 8 months to greater than 36 months. Meta-analysis and meta-regression were undertaken on both oral and injectable 12-month adherence and discontinuation data. RESULTS: In total, 61 articles were included; 46 articles examined adherence and 26 examined discontinuation. Twelve-month adherence ranged between 53.0% to 89.2% for oral (N = 7) and 47.0% to 77.4% for injectable DMTs (N = 7). Results from the meta-analysis and meta-regression show significantly higher pooled mean medication possession ratio (MPR) adherence for oral DMTs (91.0%) when compared to injectable DMTs (77.0%) over 12 months (β = -0.146; 95% CI: -0.263 to -0.029). Results indicate major asymmetry across studies (LFK index: -5.18), proposing the presence of significant publication bias. Mean discontinuation over 12 months was between 10.5% to 33.3% for oral (N = 7) and 15.2% to 50.8% for injectable DMTs (N = 10), with meta-analysis results indicating the presence of significant heterogeneity (I2 Injectable: 99.5%; I2 Oral: 93.1%) between studies included in each subgroup. However, no appreciable difference in mean discontinuation rates across groups (Injectable: 27%; 95% Cl: 19.0%-34.0%; Oral: 24%; 95% CI: 17.0%-31.0%) was found. CONCLUSIONS: Medication adherence for oral DMTs suggests a significant improvement compared to adherence for injectable DMTs. No significant difference in discontinuation rates between oral and injectable DMTs was found. Oral DMT adherence and persistence studies are limited, given their relatively recent introduction. Suboptimal medication adherence and discontinuation issues remain present for both oral and injectable DMTs. Future studies would benefit from improved consistency in methodology, such as comparable adherence and persistence definitions. DISCLOSURES: The authors did not receive any funding for this study. Mardan and Hussain have nothing to disclose. Grech reports grants from Merck Pharmaceutical, outside the submitted work. Allan reports grants received from Merck Pharmaceutical outside the submitted work.

Effectiveness, Healthcare Resource Utilization and Adherence to Subcutaneous Interferon Beta-1a According to Age in Patients With Multiple Sclerosis: A Cohort Study Using a US Claims Database

Background: It is thought that older patients with multiple sclerosis (MS) may present with a different clinical disease phenotype, and therefore respond to subcutaneous interferon beta-1a (sc IFN β-1a) differently to younger patients. However, few real-world data are available concerning the effectiveness of sc IFN β-1a according to age. Using data from US claims databases, this cohort analysis aimed to determine the differences in relapse rates, healthcare utilization, treatment adherence, and discontinuation according to pre-defined age groups.

Methods: Patient data were pooled from the IBM® MarketScan® Commercial Claims Database and Medicare Supplemental Database. Patients with a confirmed MS diagnosis who initiated treatment with sc IFN β-1a between July 01, 2010 and December 31, 2015, along with at least 6 months continuous enrolment in a healthcare plan, were followed from first prescription (index date) until date of discontinuation, treatment switch, or end of observation period (1 year after index date).

Results: Of the 5,340 patients included in the analysis, there was a high proportion of patients free from relapse across all age groups (range: 94.1–95.4%), with a numerical decrease in the number of MRI performed by age (mean: 0.25, 18–30 years; 0.20, 31–40 years; 0.16, 41–50 years; 0.14, ≥51 years). Adherence (≥80%) was seen to increase with age (77.6%, 18–30 years; 79.6%, 31–40 years; 81.3%, 41–50 years; 84.0%, ≥51 years), at the same time as a non-significant decrease in discontinuation (incidence rate: 79.91, 73.01, 71.75, 68.71%).

Conclusion: The effectiveness of sc IFN β-1a does not appear reduced as a consequence of age in this real-world setting. Older patients had lower discontinuation rates and reduced disease activity, reflected in lower relapse rates and fewer MRI scans compared with younger patients.

Preliminary testing of a patient decision aid for patients with relapsing-remitting multiple sclerosis

Background

Multiple first-line disease modifying therapies (DMTs) are available for relapsing-remitting multiple sclerosis (RRMS), each with different characteristics. We developed an interactive patient decision aid (PtDA) to promote informed shared decision-making (SDM).

Objective

To test the preliminary effectiveness of the PtDA in participants with RRMS.

Methods

Knowledge, and decisional conflict were measured pre- and post- implementation of the PtDA, SDM after the consultation, and 6-month treatment patterns were observed. Differences in scores were analyzed using descriptive statistics and paired t-tests. Qualitative interviews with patients and neurologists were analyzed using thematic analysis.

Results

52 participants were recruited: most were female (81%), 40 years of age or younger (62%), and had experienced MS for less than 5 years (56%). After participants used the PtDA, there was a significant improvement in decisional conflict (change = 1.00; p < 0.001) and knowledge (change = 2.15, p < 0.001). Nearly all patients wanted SDM, and 25 (56%) reported this occurred in their consult. Qualitative results suggested the PtDA supported both patients and neurologists in making decisions.

Conclusion

This pilot study suggests that PtDA use helps RRMS patients and their clinician select a DMT. Future studies will assess the feasibility of implementation and the impact of the PtDA on timely DMT initiation and longer-term adherence.

Epidemiology, treatment patterns and healthcare utilizations in multiple sclerosis in Taiwan

“Real-world” data on the nationwide epidemiology and treatment patterns of multiple sclerosis (MS) is very scarce in Asia. This study is aim to evaluate the 10-years trends in epidemiology and treatment patterns of MS with Taiwan’s National Health Insurance Database (NHIRD). Patients aged 20 years or older and were newly diagnosed with MS between 2007 and 2016 were identified. The crude incidences of MS were presented annually and stratified by sex and age. Baseline characteristics and treatment patterns, particularly disease-modifying drugs (DMDs), were also analyzed. This study included 555 MS patients (mean age was 36.9 and 74.4% were female). The crude incidence rate of MS decreased slightly from 0.43 per 100,000 persons in 2007 to 0.24 per 100,000 persons in 2015. The female to male ratios remained mainly between 2 to 3. Approximately 80% of MS patients received initial DMDs, with interferon β-1a as the dominant one. Furthermore, 37.5% of MS patients received subsequent DMDs, with fingolimod being the most frequently used. The median times from diagnosis to initial and to subsequent DMDs were 77 and 1239 days, respectively. This nationwide study provides up-to-date and sophisticated estimates of MS epidemiology and treatment pattern in “real-world” setting in Taiwan.

Predictors of Adherence Among Patients With Multiple Sclerosis Using the BETACONNECT® Autoinjector: A Prospective Observational Cohort Study

Background: In patients with multiple sclerosis (MS), non-adherence to disease-modifying drug therapy is associated with an increased rate of MS relapses. Early identification of patients at risk of non-adherence would allow provision of timely and individualized support. The aim of the BETAPREDICT study was to investigate potential predictors of adherence in patients with MS in Germany treated with interferon β-1b (IFNβ-1b) using the BETACONNECT® autoinjector. Methods: BETAPREDICT was a national, multi-center, prospective, non-interventional, single-arm, 24-month cohort study of patients with relapsing-remitting MS or clinically isolated syndrome receiving IFNβ-1b via the BETACONNECT® autoinjector (ClinicalTrials.gov: NCT02486640). Injection data were captured by the autoinjector. The primary objective was to determine baseline predictors of compliance, persistence, and adherence to IFNβ-1b treatment after 12- and 24 months using multivariable-adjusted regression. Secondary objectives included evaluation of satisfaction with the autoinjector, injection site pain, vitamin and nutrient supplementation, clinical course, and patient-related outcome measures. Results: Of 165 patients enrolled, 153 were available for analysis (120 with autoinjector data). Seventy-two patients left the study prematurely. Compliance (N = 120), persistence (N = 153), and adherence (N = 120) at 24 months were 89.1, 53.6, and 41.7%, respectively. Compliance at 12- and 24 months was predicted by intake of vitamin D supplements and absence of specific injection site reactions. Positive predictors of persistence included age (at 12- and 24 months) and previous duration of treatment (at 12 months), while intake of vitamins/nutrients other than vitamin D was a negative predictor (at 12 months). Positive predictors of adherence at 24 months were age and being experienced with IFNβ-1b. Higher scores in specific SF-36 subscales were positive predictors of medication-taking behavior at 24 months. Satisfaction with the autoinjector was high at baseline and 24 months (median score: 9 out of 10). Conclusions: Compliance with IFNβ-1b treatment among participants still under observation remained high over a 24-month period, while persistence and adherence continuously declined. Multiple factors affected medication-taking behavior, including patient characteristics, treatment history, injection site reactions, patients' perception of their health and support programs. The importance of these factors may differ among patients according to their individual situation.

Study protocol for a randomised controlled trial of a web-based behavioural lifestyle programme for emPOWERment in early Multiple Sclerosis (POWER@MS1)

INTRODUCTION

Multiple sclerosis (MS) is an inflammatory and degenerative disease of the central nervous system that mainly affects young adults. Uncertainty is a major psychological burden of the disease from diagnosis to prognosis, enhanced by the pressure to make early decisions on a diverse set of immunotherapies. Watchful waiting for 1-2 years while adapting goals and lifestyle habits to life with a chronic disease represents another reasonable option for persons with MS (PwMS). A behaviour change programme based on evidence-based patient information (EBPI) is not available in standard care. This randomised controlled trial (RCT) with an embedded process evaluation investigates the efficacy and cost-effectiveness of a web-based behavioural lifestyle programme to change lifestyle behaviour and reduce inflammatory disease activity in PwMS.

METHODS AND ANALYSIS

A web-based behavioural intervention will be evaluated in an RCT aiming to recruit 328 persons with clinically isolated syndrome, suspected MS or confirmed MS for less than 1 year, who have not yet started immunotherapy. Moreover, a mixed-methods process evaluation and a health economic evaluation will be carried out. Participants will be recruited in at least 16 MS centres across Germany and randomised to an intervention group with 12 months of access to EBPI about lifestyle factors in MS, combined with a complex behaviour change programme or to a control group (optimised standard care). The combined primary endpoint is the incidence of new T2 lesions on MRI or confirmed relapses.

ETHICS AND DISSEMINATION

The study has been approved by the Ethics Committee of the Hamburg Chamber of Physicians (PV6015). Trial results will be communicated at scientific conferences and meetings and presented on relevant patient websites and in patient education seminars.

TRIAL REGISTRATION NUMBER

Comparison of first-line and second-line use of fingolimod in relapsing MS: The open-label EARLIMS study

Background

Treatment of MS often begins with low-efficacy injectable disease-modifying therapy (iDMT).

Objectives

To compare the effect of fingolimod 0.5 mg/day on clinical, MRI, patient-reported, and safety outcomes, in treatment-naïve and previously treated (≥1 iDMT) patients with early MS.

Methods

EARLIMS was a multicentre, open-label, non-randomized, parallel-group phase 3 b/4 study in Australia and Spain. Patients with relapsing–remitting MS, Expanded Disability Status Scale (EDSS) score <4.0, and ≥1–5 years since diagnosis, received daily fingolimod for 48 weeks. The primary endpoint was annualized relapse rate (ARR).

Results

Of 347 patients enrolled at 51 sites (treatment-naïve, 200 [57.6%]; previously treated, 147 [42.4%]), 320 completed the study (treatment-naïve, 184 [92.0%]; previously treated, 136 [92.5%]), but the study remained underpowered (planned enrolment, n = 432). Fingolimod reduced ARR to similar levels in both treatment-naïve (mean ARR [95% confidence interval], 0.21 [0.14, 0.29]) and previously treated groups (0.30 [0.20, 0.41]; p = 0.1668). There were no new safety signals.

Conclusions

Fingolimod appeared equally effective as first- or second-line therapy in relapsing MS. There was a trend for better outcomes with fingolimod in treatment-naïve patients than in those previously treated with >1 iDMT.

Reasons for switching to fingolimod in patients relapsing-remitting multiple sclerosis in France: the ESGILE study

BACKGROUND

Timely treatment switching is an important strategy in optimising management of patients with relapsing remitting multiple sclerosis (RRMS). Patient preferences, as well as clinical benefit, may contribute to the switch decision. Information on reasons determining switching choices and on outcome according to the reason for switching is scarce. Study objectives were to describe the consequences of switching to fingolimod in terms of clinical improvement according to the reasons underlying the switch and to evaluate treatment acceptability from the patient's perspective.

METHODS

This prospective observational study was conducted by 71 neurologists in France and included patients with RRMS switching to fingolimod following ≥6 months treatment with a first-line disease modifying treatment (DMT). Reasons for switching were documented. Patients were evaluated at inclusion and 12 months after initiating fingolimod. Physicians documented clinical status by relapse activity, disability (EDSS) at each visit and improvement with the Clinical Global Impression - Change (CGI-C) at Month 12. Patients rated improvement at Month 12 with the Patient Global Impression - Change (PGI-C) and treatment acceptability with the ACCEPT® questionnaire. Adverse events reported during fingolimod treatment were documented.

RESULTS

Overall 232 patients were recruited of whom 190 could be analysed. Multiple reasons for switching were frequently given; 113 patients (59.4%) switched from a first-line injectable DMT. Switching was motivated by disease worsening in 161 patients (84.7%), tolerability in 35 (18.4%) and patient preference in 58 (30.5%). During the follow-up period, 38 patients (20.0%) experienced at least one exacerbation. The mean EDSS score was stable (2.0 ± 1.3 at inclusion; 2.0 ± 1.5 at M12). With the CGI-C, 67 patients (38.7%) were considered improved and 23 (13.3%) worsened. Although no obvious differences in CGI-C ratings were observed as a function of the reason for switching, when patient preferences entered into the decision, the proportion of patients considered minimally improved was somewhat higher (37.7%) and the proportion considered unchanged somewhat lower (41.5%). With the PGI-C, more patients rated themselves improved than were rated as improved by the physician: of 64 patients rated as 'no change' on the CGI-C, 21 (32.8%) rated themselves as 'improved' and 10 (15.6%) as 'worsened'. The overall level of agreement between the two measures was moderate (κ = 0.48 [95% CI: 0.35 - 0.60]). The mean general treatment acceptability score on the ACCEPT® questionnaire was 42.7 [95%CI: 34.5 - 50.9] at inclusion (reflecting acceptability of the previous DMT) and 64.6 [95%CI: 57.6 - 71.6] at M12 (reflecting acceptability of fingolimod). Mean dimension scores ranged from 36.7 for effectiveness to 72.2 for medication inconvenience at inclusion and from 63.4 for effectiveness to 96.8 for medication inconvenience at M12. The frequency and nature of reported adverse events was consistent with the well-characterised safety profile of fingolimod.

CONCLUSION

Most patients switching from a first DMT to fingolimod do so due to persistent disease activity during the initial treatment, although patient preferences are also important. Switching is followed by a reduction in disease activity, perceived improvement in the clinical state of the patient and improved acceptability of treatment.

Persistence, adherence, healthcare resource utilisation and costs for interferon Beta in multiple sclerosis: a population-based study in the Campania region (southern Italy)

Background

To differentiate five formulations of Interferon Beta for the treatment of multiple sclerosis (MS) in clinical practice, by analysing persistence, adherence, healthcare resource utilisation and costs at population level.

Methods

In this population-based study, we included individuals with MS living in the Campania Region of Italy from 2015 to 2017, on treatment with intramuscular Interferon Beta-1a (Avonex® = 618), subcutaneous pegylated Interferon Beta-1a (Plegridy® = 259), subcutaneous Interferon Beta-1a (Rebif® = 1220), and subcutaneous Interferon Beta-1b (Betaferon® = 348; and Extavia® = 69). We recorded healthcare resource utilisation from administrative databases (hospital discharges, drug prescriptions, MS-related outpatients), and derived costs from the Regional formulary. We classified hospital admissions into MS-related and non-MS-related. Persistence (time to switch to other disease modifying treatments (DMTs)), and adherence (medication possession ratio (MPR) = medication supply obtained/medication supply expected during follow-up period) were calculated.

Results

Patients treated with Rebif® were younger, when compared with other Interferon Beta formulations (p < 0.01). The probability of switching to other DMTs was 60% higher for Betaferon®, 90% higher for Extavia®, and 110% higher for Plegridy®, when compared with Rebif® (p < 0.01). Plegridy® presented with 7% higher adherence (p < 0.01), and Betaferon® with 3% lower adherence (p = 0.03), when compared with Rebif®. The probability of MS-related hospital admissions was 40% higher in Avonex® (p = 0.03), 400% higher in Betaferon® (p < 0.01), and 60% higher in Plegridy® (p = 0.04), resulting into higher non-DMT-related costs, when compared with Rebif®.

Discussion

Interferon Beta formulations presented with different prescription patterns, persistence, adherence, healthcare resource utilisation and costs, with Rebif® being used in younger patients and with less MS-related hospital admissions.

Switching to fingolimod in PREFERMS: Effect of treatment history and naïvety on clinical, MRI and treatment satisfaction outcomes✰

BACKGROUND

Injectable disease-modifying therapies (iDMTs) are often used as first-line treatments for relapsing multiple sclerosis. Fingolimod is frequently used following treatment with iDMTs. Whether prior iDMT treatment impacts the effectiveness of subsequent fingolimod therapy is unclear. Here, we assessed switching from iDMTs to fingolimod, and the impact of treatment history on fingolimod escalation using data from the 12-month 'Prospective, Randomized, active-controlled, open-label study to Evaluate patient retention on Fingolimod versus approved first-line disease-modifying thErapies in adults with Relapsing-remitting Multiple Sclerosis' (PREFERMS). The study design and results at the end of randomized treatment (EoRT) in PREFERMS have been published.

METHODS

Both treatment-naïve patients and those who had previously received an iDMT were eligible for enrolment in PREFERMS, and one treatment switch was permitted on study. Pre-specified exploratory analyses compared outcomes in those randomized to fingolimod or to an iDMT at end of study (EoS), which included time spent on randomized and on switch treatment. Post hoc exploratory analyses (unadjusted for multiplicity owing to the large number of comparisons) among patients randomized to an iDMT who switched to fingolimod, compared outcomes longitudinally before (EoRT) and after (EoS) switching, and compared outcomes at EoRT and EoS among subgroups stratified by iDMT-treatment history. Outcomes included brain volume, various measures of gadolinium-enhancing [Gd+] lesion counts, annualized relapse rate (ARR), Symbol Digit Modalities Test (SDMT) score, patient-reported treatment satisfaction using the Medication Satisfaction Questionnaire (MSQ) and adverse event (AE) rates.

RESULTS

At EoS, 255 of 439 patients randomized to an iDMT had switched to fingolimod and 27 of 436 patients randomized to fingolimod had switched to an iDMT. By EoS, 44.2% of total treatment exposure in the iDMT group was to fingolimod and the mean time spent on fingolimod in this group was 220 days (approximately 7 months). Outcomes in the fingolimod group at EoS (brain volume, changes in Gd+ lesion counts, ARR, oral SDMT score and MSQ score) were similar to those seen at EoRT, but in the iDMT group these outcomes were more favorable at EoS than at EoRT and were similar to rates seen in the fingolimod group. Among patients who switched from iDMT to fingolimod, there were longitudinal improvements in ARR (EoRT, 0.3 [95% confidence interval (CI), 0.2-0.4]; EoS, 0.2 [0.1-0.3]; odds ratio, 0.5 [0.3-0.9]) and in treatment satisfaction (proportion of patients with MSQ > 5; EoRT, 67.4%; EoS, 90.4%; odds ratio, 5.7 [95% CI, 3.4-9.4]) after fingolimod treatment, and changes in brain volume, Gd+ lesion count, and AEs or AEs causing discontinuation were also more favorable at EoS than at EoRT. In all patient groups stratified by iDMT-treatment history, differences in outcomes narrowed or disappeared after fingolimod treatment.

CONCLUSION

These analyses indicate that patients in PREFERMS had improved outcomes within months of switching to fingolimod from an iDMT and that improvements occurred irrespective of the number of iDMTs previously administered. These data provide a unique opportunity to explore clinical, radiological and safety outcomes associated with a range of clinically relevant treatment pathways.

Real-World Treatment of Patients with Multiple Sclerosis per MS Subtype and Associated Healthcare Resource Use: An Analysis Based on 13,333 Patients in Germany

INTRODUCTION

The aim of this study was to describe the real-word treatment and associated healthcare resource use (HCRU) of multiple sclerosis (MS) patients, as stratified by different MS subtypes.

METHODS

All patients with MS continuously insured by two German statutory healthcare insurance funds from 2011 to 2015 were enrolled. These patients were categorized into four subgroups according to their MS type as follows: clinically isolated syndrome (CIS); relapsing remittent MS (RRMS); primary progressive MS (PPMS); and secondary progressive MS (SPMS). Sociodemographic characteristics, treatments, and HCRU for 2015 were analyzed. Treatment cascades for treatment-naïve patients were also determined.

RESULTS

A total of 13,333 patients with MS were identified. The largest proportion of patients had RRMS (41.9%), followed by PPMS (17.1%). Mean age of the enrolled patients was 50.2 years, and 70.7% were female. Among all patients, 38.3% of those with CIS, 22.4% with PPMS, 69.6% with RRMS, and 33.9% with SPMS received a prescription of a disease-modifying immunomodulatory agent, with interferon beta-1a being the most frequently prescribed agent. Likewise, 14.5, 18.5, 19.9, and 21.5% of patients with CIS, PPMS, RRMS, and SPMS, respectively, received a flare-up treatment with glucocorticoids. MS-associated overall costs, including indirect costs for MS-associated days absent from work, were € 16,433, with costs related to MS medication (€ 8770; 53.4%) being the main driver of costs in all subgroups. MS-associated costs according to MS subtypes were € 12,427 for CIS patients, € 14,459 for PPMS patients, € 20,583 for RRMS patients, and € 17,554 for SPMS patients.

CONCLUSION

Among the four MS subtypes, RRMS patients most often received a disease-modifying immunomodulatory treatment. Consequently, healthcare costs were highest for patients with this MS subtype. Contrary to the treatment guideline, a substantial percentage of patients with CIS, RRMS, and SPMS did not receive any disease-modifying immunomodulatory treatment.

Medication beliefs in first-line and second-line treated multiple sclerosis patients

BACKGROUND

Immune treatments of multiple sclerosis (MS) can be classified in first-line and second-line approaches. While in both treatment efficacy is often not easy to assess in the short-term, treatment and illness beliefs may differ in first-line and second-line treated patients. The current study aimed to assess differential beliefs about medicine and illness perception between these groups based on the hypothesis that they are closely connected to adherence behaviour.

METHODS

An online survey through the website of the German MS Society was performed investigating beliefs about immune treatments as well as the patients' illness perceptions with validated questionnaires. Demographic factors, disability and self-reported adherence rates were studied as moderator variables.

RESULTS

In total, 630 patients participated. Data of 433 first-line treated and 192 second-line treated patients with MS (PwMS) were analysed. Necessity beliefs and also concerns beliefs were significantly higher in second-line treated PwMS (MANCOVA p =.001 and p =.006) and generally in patients with higher disability, while illness perception did not differ between groups. Self-assessed adherence rates were around 70% for oral treatments and injectables irrespective of first-line or second-line. Nonadherence was below 5% for infusion treatments. However, most patients reported only single omissions.

CONCLUSION

The current study reveals differential behavioural attitudes between first-line versus second-line-treated PwMS. However, follow-up studies are needed to further unravel the relationship between behavioural attitudes and treatment adherence.

BetaEval Global: Prospective, Multinational, Observational Cohort Study of Patients Using BETACONNECT®

PURPOSE

Patients with multiple sclerosis (MS) would benefit from continued long-term treatment with disease-modifying therapies, and autoinjectors may help improve patients' satisfaction with therapy, thereby increasing adherence rates. BETACONNECT® is an autoinjector for interferon beta-1b designed to improve the injection experience for patients. The BetaEval Global study assessed medication intake in patients using BETACONNECT to further investigate the value of this autoinjector.

PATIENTS AND METHODS

The BetaEval Global study was a prospective, non-interventional cohort study across multiple European countries in patients with relapsing-remitting MS (RRMS) or clinically isolated syndrome (CIS) who were starting interferon beta-1b treatment. The decision to administer interferon beta-1b was made independently of the study. Patients were assessed at the initial visits and planned follow-up visits at Weeks 4, 12, and 24. The primary outcome variable was compliance with therapy based on the medication possession ratio (MPR). Injections were automatically recorded by the BETACONNECT device or, in some instances, self-reported by the patients. This allowed for a complete dataset that could be used in the calculation of the MPR.

RESULTS

Four hundred ninety-eight patients were enrolled and completed 93.9%, 95.2%, and 95.4% of prescribed injections at Weeks 4, 12, and 24, respectively. Similarly, 76.4% (n=318), 76.6% (n=297), and 81.1% (n=284) of patients completed at least 80% of their prescribed injections. Median scores assessing patient satisfaction with the autoinjector were consistently high across the study.

CONCLUSION

Overall, the results from BetaEval Global demonstrated that in this cohort of patients with RRMS or CIS on interferon beta-1b, use of the BETACONNECT autoinjector was associated with high rates of compliance, adherence, and patient satisfaction.

Exploring Adherence to First-Line and Second-Line Immunotherapies in Multiple Sclerosis: An Interview Study

Background

Treatment adherence is fundamental in multiple sclerosis (MS) management. Adherence rates vary significantly between studies, ranging from 30% to almost 90%, depending on assessment method and medication type. This study aimed to identify patient-related categories associated with treatment modification or discontinuation in people with MS receiving either first- or second-line treatment.

Methods

Semistructured interviews were performed with 23 people with MS: 11 receiving first-line treatment and 12 receiving second-line treatment. Medication history, experiences with previous medications, decision-making processes regarding immunotherapy, adherence behavior, and reasons for adherence/nonadherence were explored using open-ended questions. Qualitative content analysis was performed using a combined deductive-inductive approach in building a coding frame. Differences in coding frequencies were compared between the two groups and analyzed quantitatively. Cohen's kappas of 0.76 for people with MS receiving first-line treatment and 0.64 for the second-line sample were achieved between the two coders.

Results

One key reason for nonadherence reported by first-line-treated people with MS was burdensome side effects, and for adherence was belief in medication effectiveness. In people with MS receiving second-line treatment, lack of perceived medication effectiveness was a key category related to changes in or discontinuation of immunotherapy. Reasons for adherence were positive illness beliefs/perceptions and belief in highly active disease. Intentional nonadherence was a major issue for first-line treatment and less relevant for second-line treatment.

Conclusions

These results indicate specific differences in factors mitigating adherence in people with MS receiving first- and second-line treatment.

Multiple modality approach to assess adherence to medications across time in Multiple Sclerosis

BACKGROUND

Medication adherence is especially challenging in a chronic condition such as Relapsing Multiple Sclerosis (RMS). Medication adherence among persons with MS (PwMS) is usually assessed via a single measure, mostly electronic pharmacy records.

OBJECTIVES

Assess medication adherence in multiple modes across time among PwMS; examine consistency across time and associations between measures.

METHODS

PwMS (N = 194) were surveyed prospectively at three time points (baseline, 6 and 12 months later) and their health records and medication claims were retrospectively obtained. Adherence score was based on medication possession ratio (MPR) and two patient-reported outcome (PRO) measures. Electronic monitoring devices assessing medication adherence were also initiated.

RESULTS

MPR of each nonadherent PwMS, once compared to medical records containing prescription changes, was found as underestimating adherence. MPR was between the two PROs in identifying nonadherence and associations between the measures and across time was moderate (Kappa ranged 0.37-0.42). The use of electronic monitoring devices was not adopted by patients. A score indicated adherence as 66% and 64.9% at Time1 and Time 2, respectively, with 21.1% of PwMS nonadherent at both time points. Adherence did not vary significantly by DMT type.

CONCLUSIONS

Being a dynamic behavior, medication adherence should be repeatedly monitored by using multiple modalities and focused on in clinician-patient encounters, especially in chronic diseases such as MS, which requires long-term treatments. Applying PROs in monitoring medication adherence would facilitate implementation of Participatory Medicine and patient-centered strategies in MS care.

Comparative Effectiveness of Rituximab and Other Initial Treatment Choices for Multiple Sclerosis

Importance

Comparative real-world effectiveness studies of initial disease-modifying treatment (DMT) choices for relapsing-remitting multiple sclerosis (RRMS) that include rituximab are lacking.

Objective

To assess the effectiveness and drug discontinuation rates of rituximab among patients with newly diagnosed RRMS compared with injectable DMTs, dimethyl fumarate, fingolimod, or natalizumab.

Design, Setting, and Patients

This retrospective cohort study used prospectively collected data to examine specialized care of 2 Swedish county-based community samples of patients with RRMS. Patients with RRMS who received diagnoses from January 1, 2012, to October 31, 2015, who resided in Stockholm or Västerbotten Counties were identified from a Swedish multiple sclerosis registry.

Main Outcomes and Measures

All reasons for drug discontinuation of initial treatment choice (main outcome) and specific reasons for switching (secondary outcomes) were analyzed with multivariable Cox regression, including propensity scores.

Results

Among 494 patients (median [interquartile range] age, 34.4 [27.4-43.4] years; 158 men [32.0%]), 215 received an injectable DMT (43.5%); 86 (17.4%), dimethyl fumarate; 17 (3.4%), fingolimod; 50 (10.1%), natalizumab; 120 (24.3%), rituximab; and 6 (1.2%), other DMT. Regional preferences were pronounced, with 42 of 52 (81%) and 78 of 442 (18%) receiving rituximab in Västerbotten and Stockholm, respectively. The annual discontinuation rate for rituximab, injectable DMTs, dimethyl fumarate, fingolimod, and natalizumab were 0.03, 0.53, 0.32, 0.38, and 0.29, respectively. Continued disease activity was the main reason for discontinuation of injectable DMTs, dimethyl fumarate, and fingolimod; positive John Cunningham virus serology results were the main reason for discontinuation of natalizumab. Rate of clinical relapses and/or neuroradiologic disease activity were significantly lower for rituximab compared with injectable DMTs and dimethyl fumarate, with a tendency for lower relapse rates also compared with natalizumab and fingolimod. The annual discontinuation rate of initial treatment choice was significantly lower in Västerbotten compared with Stockholm (0.09 and 0.37, respectively).

Conclusions and Relevance

Rituximab was superior to all other DMT in terms of drug discontinuation and displayed better clinical efficacy compared with injectable DMTs and dimethyl fumarate with borderline significance compared with natalizumab and fingolimod. The county where rituximab constituted the main initial treatment choice displayed better outcomes in most measured variables. Collectively, our findings suggest that rituximab performs better than other commonly used DMTs in patients with newly diagnosed RRMS.

Development and usability testing of a patient decision aid for newly diagnosed relapsing multiple sclerosis patients

BACKGROUND

Multiple sclerosis (MS) patients often struggle with treatment decisions, in part due to the increasing number of approved disease modifying therapies, each with different characteristics, and also since physicians can struggle to identify which of these characteristics matter most to each individual patient. Decision uncertainty can contribute to late treatment initiation and treatment non-adherence-causes of 'undertreatment' in MS. An interactive online patient decision aid that informs patients of their options, considers their individual preferences and goals, and facilitates conversations with their physicians, could improve how patients with relapsing forms of MS make evidence-based treatment decisions.

OBJECTIVE

To develop and evaluate a prototype patient decision aid (PtDA) for first-line disease modifying therapies for relapsing-remitting multiple sclerosis.

METHODS

Informed by previous studies and International Patient Decision Aid Standards guidelines, a prototype PtDA was developed for patients with relapsing multiple sclerosis considering first line treatment. Patients with relapsing multiple sclerosis were recruited from the University of British Columbia's Multiple Sclerosis Clinic to participate in either an online survey or a focus group. Online survey participants completed the PtDA, followed by measures of acceptability, usability, and preparedness for decision-making, and provided general feedback. Focus group participants assessed usability of the revised PtDA. The analysis of qualitative and quantitative data led to improvements of the PtDA prototype.

RESULTS

The prototype PtDA received high ratings for acceptability and usability, and after its use, participants reported high-levels of preparedness for decision-making. Analysis of all qualitative data identified three key themes: the need for credible information; the usefulness of the PtDA; and the importance of normalizing and sharing experiences. Nine content areas were identified for revision. Overall, participants found the PtDA to be a valuable tool for facilitating treatment decisions.

CONCLUSIONS

This mixed methods study has led to the development of a PtDA that can support patients with RRMS as they make treatment decisions. Future studies will assess the feasibility of implementation and the impact of the PtDA on both the timely treatment initiation and longer-term adherence.

Persistence and adherence to interferon and glatiramer acetate in patients with multiple sclerosis

Objectives

To analyse persistence and adherence in patients with multiple sclerosis receiving first-line treatment with subcutaneous glatiramer acetate 20 mg (GA), subcutaneous interferon β1a (IFNβ1a-sc), intramuscular interferon β1a (IFNβ1a-im) and subcutaneous interferon β1b (IFNβ1b-sc) and to identify associated factors and reasons for discontinuation.

Methods

An observational retrospective study was performed between January 1999 and November 2014. Persistence was defined as the time from treatment initiation until discontinuation, and adherence as the number of units dispensed since treatment initiation until its interruption divided by the theoretical number of units needed to cover said period as a percentage. A patient was considered adherent if ≥95%. Persistence was measured using the Kaplan-Meier method and univariate Cox regression; adherence was measured using a univariate binary logistical regression model.

Results

The study included 224 patients. The median persistence was 1349 days (95% CI 1017.4 to 1680.6). Patients receiving IFNβ1a-im continued treatment for a longer time (1720 days; 95% CI 1196.8 to 2243.2), while patients treated with IFNβ1a-sc had the lowest persistence (771 days; 95% CI 377.4 to 1164.6) (HR=1.7; 95% CI 1.02 to 2.72). Patients with Expanded Disability Status Scale (EDSS) 1.5-6 discontinued treatment earlier than those with EDSS 0-1 (HR 1.5; 95% CI 1.01 to 2.25); 94.4% of patients discontinued treatment due to medical decision, primarily due to lack of efficacy (24.6%) and adverse effects (17.4%), while 80.8% of patients had good adherence. GA had the highest adherence, with no major difference from IFNβ1a-im, while IFNβ1b-sc showed the highest non-adherence (OR 3.5; 95% CI 1.29 to 9.28).

Conclusions

The persistence levels obtained were lower than in similar studies. EDSS was identified as an independent predictor of treatment interruption. Acceptable adherence was achieved among the population, comparable to other studies and influenced by the drug.

Cost-effectiveness of Teriflunomide Compared to Interferon Beta-1b for Relapsing Multiple Sclerosis Patients in China

Background and Objective

Teriflunomide is a once-daily oral immunomodulatory agent approved in 80 countries for the treatment of patients with relapsing multiple sclerosis (RMS). The study objective was to estimate the cost effectiveness of teriflunomide (14 mg tablet, daily) versus interferon beta-1b (250 mcg subcutaneous injection, every other day) among RMS patients from the Chinese healthcare system perspective.

Methods

A Markov model with annual cycles and a lifetime horizon was utilized to assess cost-effectiveness of teriflunomide in comparison with interferon beta-1b in RMS patients. Treatment effects, including 3-month confirmed disability worsening and annualized relapse rate, were derived from a network meta-analysis. Cost inputs included costs related to treatment acquisition, administration, monitoring, natural disease management through Expanded Disability Status Scale states, relapse treatment, and adverse event management. These costs were calculated as the product between unit costs from published sources and healthcare resource utilization patterns identified in a survey conducted among 11 neurologists across different areas in China. Health effects were expressed as quality-adjusted life years (QALYs) with costs in local currency (¥) and US dollars (US$), 2018.

Results

Teriflunomide dominated interferon beta-1b and was associated with lower total costs (teriflunomide ¥1,887,144 vs interferon beta-1b ¥2,061,393) and higher QALYs (teriflunomide 9.60 QALYs vs interferon beta-1b 8.88 QALYs). In probabilistic sensitivity analysis, teriflunomide was dominant in 62.2% of model runs.

Conclusion

Teriflunomide is a cost-effective therapy over a lifetime time horizon compared to interferon beta-1b in the treatment of RMS patients in China. Results should be interpreted with caution as head-to-head comparisons are not available.

Adherence to Subcutaneous IFN β-1a in Multiple Sclerosis: Final Analysis of the Non-Interventional Study READOUTsmart Using the Dosing Log and Readout Function of RebiSmart®

INTRODUCTION

Patient adherence is a key determinant of treatment success in multiple sclerosis (MS). The RebiSmart^® autoinjector facilitates patient self-injection of subcutaneous interferon β-1a (sc IFN β-1a) and allows quantitative measurement of adherence via its automated dosing log. We evaluated patient adherence and patient-reported cognitive and health-economic outcomes over 2 years in patients using RebiSmart^®.

METHODS

In this non-interventional, single-arm study, enrolled patients were 12-65 years of age, had relapsing-remitting MS or a single demyelinating event, and had been prescribed 44 or 22 μg sc IFN β-1a. Quantitative adherence (proportion of scheduled injections administered) and qualitative adherence (proportion of weeks with treatment schedule correctly followed) were monitored over 2 years. Other end points included self-assessed adherence, patient-reported outcomes (fatigue, depression and quality of life), cognitive outcomes and health-economic outcomes.

RESULTS

A total of 368 of 392 (93.9%) enrolled patients were analyzed. Mean quantitative adherence was 85.3% overall (months 1-24), 89.6% for months 1-12 and 83.3% for months 13-24. No major impact on quantitative adherence was observed for sex, age (< 37 years vs. ≥ 37 years), prior medication or participation in the patient support program RebiSTAR^®. Mean qualitative adherence was 67.0% overall (months 1-24). Self-assessed adherence was reported as being higher than RebiSmart^®-monitored adherence. There was a trend toward more MS-related visits to physicians among patients with high adherence.

CONCLUSIONS

Patients using RebiSmart^® demonstrated high adherence to treatment that was associated with a slight improvement in information processing speed and working memory and an overall tendency for more intensive self-management.

Drug-use patterns and severe adverse events with disease-modifying drugs in patients with multiple sclerosis: a cohort study based on German claims data

Purpose: To describe drug-use patterns in patients with multiple sclerosis (MS) using disease-modifying drugs (DMDs) and to estimate the incidence of severe adverse events (SAEs) of treatment. Methods: We conducted a cohort study within the German Pharmacoepidemiological Research Database between January 1, 2006 and December 31, 2013. MS patients on DMDs were described in terms of clinical characteristics and drug-use patterns. Next, we assessed the incidence of AEs in new users of fingolimod, natalizumab, glatiramer acetate, and IFNβ_1a. Results: Among approximately 11 million insured members of German Statutory Health Insurance, the DMD-user cohort comprised 15,377 patients with MS, with a mean age of 39.6 years and 68% females. Nearly half of all DMD users had a diagnosis of depression, with prevalence ranging from 40.1% for IFNβ_1a to 62.3% for immunoglobulins. The overall rate of MS relapses per patient and year was 0.34 (95% CI 0.33-0.34). During an average follow-up of 1,650 days, the majority (42.4%) of MS patients were adherent to DMD treatment ("continuous single users"), followed by patients interrupting treatment (39.5%, "interrupters"). Switch of DMD treatment (11.9%) was less frequent, and only 5.6% discontinued treatment. Treatment discontinuation was most common in users of natalizumab (7.5%) and IFNβ_1b (7.0%). The most frequent SAE was hospitalization for depression, followed by any infectious disease and any malignancy. The incidence rate of all adverse events did not significantly differ across different DMDs. Conclusion: Treatment discontinuation with DMDs and treatment switch were rare. Causes of rather frequent DMD-treatment interruption have to be evaluated in further studies based on primary data collection. Active safety monitoring of new DMDs based on claims data requires large data sets to detect rare AEs and availability of up-to-date data.

Outcomes of Stable Multiple Sclerosis Patients Staying on Initial Interferon Beta Therapy Versus Switching to Another Interferon Beta Therapy: A US Claims Database Study

INTRODUCTION

This study was designed to assess real-world outcomes of patients with multiple sclerosis (MS) who were stable on interferon (IFN) beta therapy in the year prior to switching to another IFN beta therapy versus those who continued on the initial treatment.

METHODS

This study used administrative claims from MarketScan Commercial Claims and Encounters Database, from January 1, 2010, to March 31, 2015, to identify MS patients aged 18-64 years who remained relapse free for at least 1 year while continuously treated with an IFN beta therapy. Stable patients remaining on their initial IFN beta therapy (no-switch patients) were matched with stable patients who switched IFN beta therapy (switch patients) using propensity score matching (first claim = index date). Outcome measures included annualized relapse rate (ARR), the percentage of patients who relapsed, medication possession ratio, and the proportion of days covered and were measured during the year following the index date.

RESULTS

This study identified 531 patients in the no-switch group and 177 patients in the switch group, with subsets of 270 patients in the no-switch group and 90 patients in the switch group stable on intramuscular (IM) IFN beta-1a therapy. All outcomes during the follow-up year were significantly better in the no-switch group than in the switch group. For all patients, ARR in the switch group was more than twice that in the no-switch group (P = 0.002). For patients stable on IM IFN beta-1a at baseline, ARR was twice as high in the switch group as in the no-switch group (P = 0.012).

CONCLUSION

Among all patients stable on IFN beta therapy and the subset stable on IM IFN beta therapy in particular, those who remained on therapy had significantly better outcomes than those who switched to another IFN beta therapy.

The BETACONNECT™ system: MS therapy goes digital

Adherence to long-term treatment in chronic diseases such as multiple sclerosis is challenging. Many disease-modifying drugs (DMDs) for MS need to be injected. Injection devices may improve satisfaction with the injection procedure and boost adherence. Meeting patients' needs in handling and design of autoinjectors and other supporting elements may be key to successful therapy. The BETACONNECT™ system is a platform-based approach in DMD therapy. It combines autoinjector technology with digital tools to support patient self-management and facilitate communication between patients and healthcare providers. Here, we describe the components of the BETACONNECT system and review data on patients' satisfaction with the BETACONNECT autoinjector and how it compares to other devices. Additionally, we present first data on patients' satisfaction with the myBETAapp™.

Treatment retention on fingolimod compared with injectable multiple sclerosis therapies in African-American patients: A subgroup analysis of a randomized phase 4 study

BACKGROUND

Suboptimal persistence with injectable disease-modifying therapies (iDMTs; interferon beta-1a/b, glatiramer acetate) is common in patients with relapsing forms of multiple sclerosis (MS), reducing the effectiveness of these agents. Adherence to, and persistence with, an effective therapy is important for patient populations at increased risk of rapid disease progression. African-American individuals with multiple sclerosis may experience a more aggressive disease course than Caucasian patients, with a greater risk of developing ambulatory difficulties and other disabilities, and may also have a diminished response to some disease-modifying therapies compared with patients of other ethnicities. Retention on oral fingolimod and on iDMTs was evaluated in a post hoc analysis of data from African-American patients in the parallel-group, 48-week 'Prospective, Randomized, active-controlled, open-label study to Evaluate patient retention on Fingolimod versus approved first-line disease modifying thErapies in adults with Relapsing-remitting Multiple Sclerosis' (PREFERMS).

METHODS

In PREFERMS, patients with relapsing-remitting MS aged 18-65 years with an Expanded Disability Status Scale score ≤6 enrolled at 117 US study sites were treatment-naïve or had received only one iDMT class. Patients were randomized 1:1 (fingolimod 0.5 mg/day:preselected iDMT) using an interactive voice-and-web-response system without blinding, followed up quarterly, and allowed one study-approved treatment switch after 12 weeks, or earlier, for efficacy or safety reasons only. The primary outcome was patient retention on randomized treatment over 48 weeks. In this post hoc analysis of African-American patients in PREFERMS, outcome variables included rate of patient retention on randomized treatment, reasons for discontinuing randomized treatment, patient-reported treatment satisfaction, and safety. Clinical and radiographic outcomes such as annualized relapse rate, brain volume loss, and lesion count changes were also investigated.

RESULTS

In PREFERMS, 141 of 875 patients (16.1%) randomized to a study drug were African-American. Analysis of data for the full analysis set of 67 patients receiving fingolimod and 69 receiving iDMTs showed that the retention rate over 48 weeks was significantly higher with fingolimod than with iDMTs (80.6% [n = 54] vs 30.4% [n = 21]; between-group difference: 50.2%; 95% confidence interval 35.8-64.6%; p < 0.0001). The most common treatment switch was from an iDMT to fingolimod for injection-related reasons, and patient satisfaction was greater with fingolimod than with iDMTs. Adverse events were consistent with the respective prescribing information for each treatment.

CONCLUSION

In PREFERMS, fingolimod was associated with better treatment retention than iDMTs in African-American patients. Optimal outcomes in the management of multiple sclerosis depend on good persistence with treatment, and this is particularly important in patient populations at increased risk of a rapidly progressing disease course.

Phase IV study of retention on fingolimod versus injectable multiple sclerosis therapies: a randomized clinical trial

OBJECTIVE

In relapsing-remitting multiple sclerosis (RRMS), suboptimal adherence to injectable disease-modifying therapies (iDMTs; interferon β-1a/b, glatiramer acetate) is common, reducing their effectiveness. Patient retention on oral fingolimod and iDMTs was evaluated in PREFERMS, a randomized, parallel-group, active-controlled, open-label, 48-week study.

METHODS

Patients were included if they had RRMS, were aged 18-65 years and had Expanded Disability Status Scale score up to 6, enrolled at 117 US study sites, were treatment naïve or had received only one iDMT class. Patients were randomized 1:1 (fingolimod 0.5 mg/day; preselected iDMT) by interactive voice-and-web-response system without blinding, followed up quarterly, and allowed one study-approved treatment switch after 12 weeks, or earlier for efficacy or safety reasons. The primary outcome was patient retention on randomized treatment over 48 weeks. Secondary endpoints included patient-reported outcomes, brain volume loss (BVL), and cognitive function.

RESULTS

Analysis of 433/436 patients receiving fingolimod and 428/439 receiving iDMTs showed that patient retention rate was significantly higher with fingolimod than with iDMTs [352 (81.3%) versus 125 (29.2%); 95% confidence interval 46.4-57.8%; p < 0.0001]. The most common treatment switch was from iDMT to fingolimod for injection-related reasons. Patient satisfaction was greater and BVL less with fingolimod than with iDMTs, with no difference in cognitive function. Adverse events were consistent with established tolerability profiles for each treatment.

CONCLUSIONS

In RRMS, fingolimod was associated with better treatment retention, patient satisfaction and BVL outcomes than iDMTs. Patients may persist with iDMTs, but many may switch treatment if permitted. Treatment satisfaction fosters adherence, a prerequisite for optimal outcomes.

Cost-Effectiveness of Peginterferon Beta-1a and Alemtuzumab in Relapsing-Remitting Multiple Sclerosis

BACKGROUND

Multiple sclerosis (MS) is a chronic inflammatory disorder of the central nervous system, affecting 2.5 million people globally and 400,000 people in the United States. While no cure exists for MS, the goal is to manage the disease using disease-modifying therapies (DMTs), which have been shown to slow disease progression and prevent relapses. Relapsing-remitting MS (RRMS) is the most common form of MS at the time of diagnosis. Peginterferon beta-1a (PEG) and alemtuzumab (ALT) were recently approved and have demonstrated good clinical outcomes, including reduced relapse rates in clinical trials. High costs associated with these DMTs necessitates cost-effectiveness analyses to understand their overall value in RRMS management.

OBJECTIVES

To assess the cost-effectiveness of (a) Model 1: PEG relative to intramuscular interferon beta-1a (IM IFN), subcutaneous interferon beta-1b (SC IFN), glatiramer acetate 20 mg per mL (GA), fingolimod (FIN), natalizumab (NAT), and dimethyl fumarate (DMF), and (b) Model 2: ALT relative to subcutaneous interferon beta-1a 44 μg (IFN beta-1a 44 μg). Both analyses were conducted from a U.S. third-party payer perspective.

METHODS

Two static decision models were used to compare the cost-effectiveness of PEG and ALT over a 1-year and a 2-year time horizon, respectively. Model inputs were drug acquisition costs (wholesale acquisition cost from RED BOOK); drug administration and monitoring costs (package inserts and Centers for Medicare & Medicaid Services 2015 Physician Fee Schedule); relapse rates and relapse rate reduction (clinical trials); and cost of managing relapses (published literature). All costs were adjusted to 2015 U.S. dollars using the medical care component of the Consumer Price Index. Outcomes measured were total cost of therapy per patient, cost per relapse avoided, and incremental cost-effectiveness ratios (ICERs) calculated as cost per relapse avoided. Sensitivity analysis was conducted to test model robustness given the uncertainty of model inputs and study assumptions.

RESULTS

Model 1 results showed that PEG dominated IM IFN and GA, compared with SC IFN; PEG had an ICER of $1,978,000 per relapse avoided. Compared with FIN, NAT, and DMF, PEG was less expensive and less effective. Model 2 showed that ALT had an ICER of $25,276 per relapse avoided relative to IFN beta-1a 44 μg.

CONCLUSIONS

In patients with RRMS, PEG is a viable alternative when compared with the DMTs in our model. Deciding whether to choose PEG over other DMTs would depend on multiple factors. On the other hand, ALT had an ICER of $25,276 cost per relapse avoided relative to IFN beta-1a 44 μg. The study results will assist payers in evaluating different medication choices for effective therapy.

Adherence to disease-modifying therapies in patients with multiple sclerosis

BACKGROUND

Multiple sclerosis (MS) is a chronic, inflammatory progressive demyelinating disease of the central nervous system. MS is one of the main causes of disability among young adults, and its management is a serious challenge for the healthcare system.

PURPOSE

The main purpose of this study was to examine adherence to first-line disease-modifying therapy (DMT) in MS patients using the self-report Multiple Sclerosis Treatment Adherence Questionnaire (MS-TAQ).

MATERIALS AND METHODS

The participants consisted of 226 MS patients (166 women and 60 men) who were treated with first-line immunomodulatory DMT. This study used a questionnaire designed by the authors, which contained questions about sociodemographic data, and the Polish version of the MS-TAQ.

RESULTS

The overall adherence was 76.5% according to the first criterion (missed ≥1 injection or tablet). There were no statistically significant differences due to sociodemographic variables between adherent and nonadherent patients. However, patients taking Avonex^® significantly more often belonged to the adherent group (P=0.042). The most frequently mentioned reasons why nonadherent patients forget to take the drug included the following: too busy in their daily activities, indisposition to take the drug, unwillingness to take the drug, interference with daily activities, and dissatisfaction with the drug. The degree of adherence among MS patients treated with immunomodulatory drugs is high; however, some patients do not take medications regularly.

CONCLUSION

Due to the utility of the MS-TAQ, the caregivers of MS patients are able to quickly and easily assess the occurrence of side effects, ways to cope with them, and the occurrence of barriers to taking medication.

Relapse outcomes, safety, and treatment patterns in patients diagnosed with relapsing-remitting multiple sclerosis and initiated on subcutaneous interferon β-1a or dimethyl fumarate: a real-world study

OBJECTIVE

To estimate real-world treatment patterns, safety, and relapse outcomes of subcutaneous (sc) interferon (IFN) β-1a (Rebif) vs dimethyl fumarate (DMF; Tecfidera), to treat relapsing-remitting multiple sclerosis (RRMS).

METHODS

A US retrospective chart review of 450 randomly selected adults newly diagnosed with RRMS who received sc IFN β-1a (n = 143) or DMF (n = 307) was conducted. Patients were either (a) treatment-naïve, initiating first-line treatment with sc IFN β-1a or DMF, or (b) previously treated, switching to sc IFN β-1a or DMF. Two years' follow-up data were captured. Patient characteristics, persistence, and adverse events between treatment groups were compared using t-tests or Chi-square tests. Kaplan-Meier curves with log-rank tests and Cox proportional hazards models were used to compare time to, and risk of non-persistence. Annualized Relapse Rates (ARR) were calculated using a robust variance Poisson model adjusting for covariates. Propensity scores were used to address possible selection bias.

RESULTS

One hundred and twelve patients became non-persistent, most commonly due to an adverse event (n = 37). No difference was observed in time to overall non-persistence between sc IFN β-1a and DMF patients. Among treatment-naïve patients, those receiving DMF had 2.4-times the risk (HR = 2.439, 95% CI = 1.007-5.917, p = .0483) of experiencing a discontinuation than patients receiving sc IFN β-1a. Non-persistent patients receiving DMF had 2.3-times the risk (HR = 2.311, 95% CI = 1.350-3.958, p = .0023) of experiencing an adverse event at a given time point than patients prescribed sc IFN β-1a. No differences in relapse risk or ARR between sc IFN β-1a- and DMF-treated patients were observed.

CONCLUSIONS

sc IFN β-1a-treated patients had comparable persistence and relapse outcomes, and better safety outcomes vs DMF-treated patients across 2 years.

What should a person with relapsing-remitting multiple sclerosis know? - Focus group and survey data of a risk knowledge questionnaire (RIKNO 2.0)

BACKGROUND

Risk knowledge is relevant to make informed decisions in multiple sclerosis (MS). The risk knowledge questionnaire for relapsing-remitting MS (RIKNO 1.0) was developed and piloted in Germany.

OBJECTIVE

To produce a revised RIKNO 2.0 questionnaire using mixed methodology in a European setting.

METHODS

The questionnaire was translated in seven languages. MS patient and health professional (HP) expert feedback was obtained from Germany, Italy, Estonia, Serbia, and the UK. A German web-based survey of RIKNO 2.0 compared the tool with the MS Knowledge Questionnaire (MSKQ), each one used with two versions (with/without a "don't know" DN option).

RESULTS

While RIKNO 2.0 was considered difficult, it was rated as highly educational. One item was reframed, and two new items were added. The web-based German survey (n = 708 completers) showed that the DN version did not increase participation rate and did not produce significantly higher scores. Internal consistency (Cronbach alpha) without SN response was 0.73. RIKNO 2.0 scores showed normality distribution irrespective of the answering format. Item difficulty was high ranging from 0.07 to 0.79. Less than 50% of questions were answered correctly (mean 8.9) compared to 80.4% in the MSKQ (mean 20.1). Higher numeracy competency and education were significantly, albeit weakly, associated to higher scores for both RIKNO 2.0 and MSKQ.

CONCLUSION

Including "don't know" options in knowledge questionnaires does not increase percentage of correct replies. RIKNO 2.0 is a complex questionnaire to be used in an educational context and studies on patient information. The tool is now available in seven languages.

Adherence, satisfaction and functional health status among patients with multiple sclerosis using the BETACONNECT® autoinjector: a prospective observational cohort study

BACKGROUND

Maintaining patient adherence to disease modifying drugs in multiple sclerosis is a challenge, which can be improved by autoinjectors. The BETACONNECT® is a fully electronic autoinjector for the injection of interferon beta-1b (IFN beta-1b) automatically recording injections.

METHODS

The BETAEVAL study was a prospective, observational, cohort study over 24 weeks among patients with relapsing remitting multiple sclerosis or clinically isolated syndrome treated with IFN beta-1b in Germany using the BETACONNECT®. The primary aim was to investigate treatment adherence, secondary aims included assessing satisfaction and functional health status. Adherence was evaluated from injection data recorded by the device. Patient-related data were obtained from clinical examinations and patient questionnaires.

RESULTS

Of the 151 patients enrolled, 143 were available for analysis. Thirty-four patients discontinued the study prematurely. 107/143 (74.8%) patients still used the BETACONNECT® at the end of the study. Injection data from the device at any visit was available for 107 patients. Among those, the percentage of adherent patients injecting ≥80% of doses and still participating in the study was 57.9% at week 24. 29% of patients prematurely stopped the study, 13.1% injected <80%. Among patients with BETACONNECT® data at the respective visit, the proportion of adherent patients was high over the entire study period (week 4: 81.1% [N = 95], week 12: 86.7% [N = 83], week 24: 80.5% [N = 77]). Participants (N = 143) indicated high satisfaction with the BETACONNECT®. At week 24, 98.0% of patients who completed the corresponding questionnaire (strongly) agreed that it was user-friendly, 81.2% felt confident in using it compared to their previous way and 85.5% preferred it to their previous way of injection. Injection-related pain was rated as mild to moderate at all follow-up visits. Whereas 17.2% of patients with corresponding questionnaire indicated using analgesics prior to injection at week 4, only 9.1% did at week 24. Outcomes from questionnaires assessing functional health status, depression, fatigue and cognitive function were very similar throughout the study course.

CONCLUSIONS

The majority of patients continued using the BETACONNECT® for IFN beta-1b treatment during the 24-week study period. Adherence was high among participants still using the BETACONNECT® and patients were highly satisfied with the device. Ongoing studies will evaluate long-term adherence and treatment outcomes in patients using the BETACONNECT®.
