Abstract
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. Sci Rep 2024; 14:7027.

Abstract
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.

Abstract
The 5-item Medication Adherence Report Scale (MARS-5) is a reliable and valid questionnaire for evaluating adherence in patients with asthma, hypertension, and diabetes. Validity has not been determined in multiple sclerosis (MS). We aimed to establish criterion validity and reliability of the MARS-5 in persons with MS (PwMS). Our prospective study included PwMS on dimethyl fumarate (DMF). PwMS self-completed the MARS-5 on the same day before baseline and follow-up brain magnetic resonance imaging (MRI) 3 and 9 months after treatment initiation and were graded as highly and medium adherent upon the 24-cut-off score, established by receiver operator curve analysis. Health outcomes were represented by relapse occurrence from the 1st DMF dispense till follow-up brain MRI and radiological progression (new T2 MRI lesions and quantitative analysis) between baseline and follow-up MRI. Criterion validity was established by association with the Proportion of Days Covered (PDC), new T2 MRI lesions, and Beliefs in Medicines questionnaire (BMQ). The reliability evaluation included internal consistency and the test-retest method. We included 40 PwMS (age 37.6 ± 9.9 years, 75% women), 34 were treatment-naive. No relapses were seen during the follow-up period but quantitative MRI analysis showed new T2 lesions in 6 PwMS. The mean (SD) MARS-5 score was 23.1 (2.5), with 24 PwMS graded as highly adherent. The higher MARS-5 score was associated with higher PDC (b = 0.027, P<0.001, 95% CI: (0.0134-0.0403)) and lower medication concerns (b = -1.25, P<0.001, 95% CI: (-1.93-(-0,579)). Lower adherence was associated with increased number (P = 0.00148) and total volume of new T2 MRI lesions (P = 0.00149). The questionnaire showed acceptable internal consistency (Cronbach α = 0.72) and moderate test-retest reliability (r = 0.62, P < 0.0001, 95% CI: 0.33-0.79). The MARS-5 was found to be valid and reliable for estimating medication adherence and predicting medication concerns in persons with MS.

Abstract
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.

Abstract
BACKGROUND Patients with multiple sclerosis (MS) receiving disease-modifying therapies (DMT) show published adherence rates of 27.0% to 93.8% and published persistence rates of 49.7% to 96.5%. Improvements in DMT adherence and persistence are key to optimizing MS care, and enhanced understanding could improve MS disease management and identify research gaps. This scoping literature review aims to examine the nature and findings of the literature evaluating factors associated with DMT adherence and persistence in patients with MS. METHODS Eligible articles included in the literature review were quantitative clinical studies written in English, included adherence or persistence as primary outcomes, and accounted for covariates/confounders. The articles were assessed to identify factors associated with adherence/persistence and analyzed according to DMT type (self-injectable, oral, infusion). RESULTS Fifty-eight studies (103,450 patients) were included. Study distribution by DMT type was self-injectable only (n = 41), oral only (n = 2), infusion only (n = 1), and more than 1 type (n = 14). Older age and previous DMT use were associated with increased adherence and/or persistence. Increased alcohol consumption, DMT adverse events, higher education, and higher body mass index were negatively associated with adherence and/or persistence. Greater number and severity of relapses was associated with increased adherence but decreased persistence. CONCLUSIONS Most studies examined factors associated with adherence and persistence to self-injectable DMTs. These factors should be evaluated further for oral and infusion DMTs. Insights into the modifiable factors associated with adherence and persistence could guide treatment decisions and help improve adherence and clinical outcomes.

Abstract
BACKGROUND Phramongkutklao Hospital is one of the largest military hospitals in Thailand. Beginning in 2016, an institutional policy was implemented in which medication prescription length was increased from 30 to 90 days. However, there have been no formal investigations into how this policy has impacted medication adherence among patients in hospitals. As such, this study evaluated how prescription length impacted medication adherence among dyslipidemia and type-2 diabetes patients who were treated at Phramongkutklao Hospital. METHODS This pre-post implementation study compared patients who received prescription lengths of 30 and 90 days based on information recorded in the hospital database between 2014 and 2017. Therein, we used the medication possession ratio (MPR) to estimate patient adherence. Focusing on patients with universal coverage insurance, we employed the difference-in-difference method to examine changes in adherence from before and after policy implementation, then conducted a logistic regression to test for associations between the predictors and adherence. RESULTS We analyzed data from a total of 2,046 patients, with equal amounts of 1,023 placed into the control group (no change to 90-day prescription length) and intervention group (change from 30 to 90-day prescription length). First, we found that increased prescription length was associated with 4% and 5% higher MPRs among dyslipidemia and diabetes patients in the intervention group, respectively. Second, we found that medication adherence was correlated with sex, comorbidities, history of hospitalization, and the number of prescribed medications. CONCLUSION Increasing the prescription length from 30 to 90 days improved medication adherence in both the dyslipidemia and type-2 diabetes patients. This shows that the policy change was successful for patients in the hospital considered for this study.

Abstract
Poor medication adherence is a pervasive issue with considerable health and socioeconomic consequences. Although the underlying reasons are generally understood, traditional intervention strategies rooted in patient-centric education and empowerment have proved to be prohibitively complex and/or ineffective. Formulating a pharmaceutical in a drug delivery system (DDS) is a promising alternative that can directly mitigate many common impediments to adherence, including frequent dosing, adverse effects and a delayed onset of action. Existing DDSs have already positively influenced patient acceptability and improved rates of adherence across various disease and intervention types. The next generation of systems have the potential to instate an even more radical paradigm shift by, for example, permitting oral delivery of biomacromolecules, allowing for autonomous dose regulation and enabling several doses to be mimicked with a single administration. Their success, however, is contingent on their ability to address the problems that have made DDSs unsuccessful in the past.

Abstract
BACKGROUND Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system that particularly affects people in their 30s. Oral disease-modifying therapy (DMT) offers a simple dosage form, good efficacy and safety. Dimethyl fumarate (DMF) is a frequently prescribed oral DMT medication worldwide. The aim of this study was to evaluate the impact of medication adherence on health outcomes in Slovenian persons with MS treated with DMF. METHODS Our retrospective cohort study included persons with relapsing-remitting MS on DMF treatment. The medication adherence was evaluated by AdhereR software package using the proportion of days covered (PDC) measure. The threshold was set at 90%. Health outcomes after treatment initiation were represented by relapse occurrence, disability progression and occurrence of active (new T2 and T1/Gadolinium (Gd) enhancing) lesions between first two outpatient visits and first two brain magnetic resonance imaging (MRI), respectively. For each health outcome a separate multivariable regression model was built. RESULTS The study included 164 patients. Their mean age (SD) was 36.7 (8.8) years, and the majority of patients were women (114 or 70%). Eighty-one patients were treatment naive. The mean (SD) PDC value was 0.942 (0.08) and 82% of patients were considered adherent above the 90% threshold. Older age (OR 1.06 per one year, P = 0.017, 95% CI (1.01-1.11)) and treatment naivety (OR 3.93, P = 0.004, 95% CI (1.64-10.4)) were related to higher adherence. In the 6-year follow-up period after DMF treatment initiation, 33 patients experienced a relapse. Among those, 19 required an emergency visit. Sixteen patients had a 1-point disability progression on the Expanded Disability Status Scale (EDSS) score between two consecutive outpatient visits. Thirty-seven patients were found to have active lesions between first and second brain MRI. Medication adherence showed no impact on relapse occurrence or disability progression. Lower medication adherence (10% lower PDC) was associated with higher occurrence of active lesions (OR 1.25, P=0.038, 95% CI: 1.01-1.56). Higher disability prior to DMF initiation was related to a higher risk for relapse occurrence and EDSS progression. CONCLUSION Our study showed high medication adherence among Slovenian persons with relapse-remitting MS on DMF treatment. Higher adherence was associated with lower incidence of the radiological progression of MS. Interventions for improving medication adherence should be intended for younger patients with higher disability prior treatment with DMF and those switching from alternative DMTs.

Abstract
OBJECTIVES To evaluate medication adherence to oral and parenteral disease-modifying therapies (DMTs) and to explore factors associated with medication non-adherence in patients with multiple sclerosis (MS). METHODS A cross-sectional multicentre study was conducted among patients with MS. Patients who attended outpatient clinics of neurology departments from three major referral centres were invited to participate in the study. Medication adherence was measured using the Multiple Sclerosis Treatment Adherence Questionnaire. KEY FINDINGS A total of 319 patients with MS on DMT were included in the final analyses, their average age was 35 years and more than two-thirds (72.1%) of them were women. The adherent group comprised 46.7% of patients. The results of association analyses showed that factors that were associated with adherence level were female gender (P = 0.034), non-smoking/x-smoking (P = 0.007), school education (P = 0.019), unemployment (P = 0.006), history of previous DMT (P = 0.020), longer previous treatment duration (P = 0.008), and type of current DMT (P = 0.020). Among the non-adherent patients, there were significant differences between oral and parenteral DMT users in the importance of barriers to adherence (P < 0.001). Additionally, the degree of treatment satisfaction was higher in oral users than in parenteral users (P < 0.001). CONCLUSIONS The adherence level was quite low. Gender, smoking status, education, employment status, history of previous DMT, previous treatment duration and type of current DMT were associated with medication non-adherence in our patients with MS. These factors should be considered when evaluating medication adherence, and the modifiable factors may represent potential targets for interventions to improve pharmaceutical care planning in patients with MS.

Abstract
Omalizumab, a recombinant anti-immunoglobulin E (IgE) monoclonal antibody, is indicated for moderate to severe allergic asthma, chronic spontaneous urticaria, and nasal polyps, and is approved for self-administration. However, specific guidance on identifying candidates with characteristics suitable for this type of administration is lacking. To help address this issue, this article provides practical considerations for the health care provider treating patients with omalizumab. We encourage health care providers to consider self-administration of omalizumab as an option for all appropriate, but not all, patients, and we recommend an individualized approach when considering self-administration of omalizumab.

Medication habits among persons with multiple sclerosis. Mult Scler Relat Disord 2022; 68:104224.

Abstract
BACKGROUND Though habitual behavior is part of medication-taking behavior, studies of adherence to medication among persons with relapsing remitting multiple sclerosis (PwRRMS) have not prospectively examined habit in relation to disease-modifying treatments (DMTs). OBJECTIVES 1. Examine habit dimensions - repetition, lack of awareness, and lack of control - across time and route of administration (oral vs. injectable). 2. Examine the association (prospective and cross sectional) of the dimension of repetition and the habit index with adherence and persistence in medication taking and to medication perceptions. METHODS PwMS (n = 140), in their first year of treatment with a DMT, were prospectively assessed at three time points: at baseline, 6 months later (Time 1), and 12 months later (Time 2). Clinical and demographic information were obtained in-person, as were patient-reported medication habits and medication perceptions. Adherence and persistence were assessed with a combination of self-reporting and retrospective review of medication claims. RESULTS Repeated measures analysis of variance (ANOVA), with dimension as the within-subject factor at each time point, indicated that the repetition dimensions at all points were significantly higher than lack of awareness and lack of control dimensions. Repeated measures ANOVA, with time as the within-subject factor and route of administration as between-subject factor, yielded a significant time effect in repetition and lack of awareness dimensions so that they increased across time but not in lack of control; administration route effects were found to be nonsignificant in all dimensions. Repetition at Time 1 was positively associated with patient-reported adherence at this time point (rs = 0.33, p = 0.002) but this was not consistently found at other time points . Likewise, reported repetition at Time 1 was higher among PwRMS who persisted with their medication a year later than among those who did not persist. Perceptions of medication (concern, harm, and overtreatment) were significantly negatively associated with reported repetition. CONCLUSIONS Over time, PwRMS reported an increase in two habit dimensions, repetition and lack of awareness, in medication taking. No significant differences in habit by administration modality were found. The habit dimension of repetition was significantly associated with perceptions of medication, adherence, and prospectively predicted persistence. However, the low values obtained for lack of awareness and lack of control, compared with the higher levels of repetition, indicate that the habit is not well ingrained. Hence, intervention to target habit formation and maintenance, to be tailored to the individual, are a promising venue for enhancing medication adherence and improving disease outcomes.

Abstract
Background: A poor patient adherence often limits the real-world effectiveness of an oral disease-modifying therapy (DMT) for multiple sclerosis (MS). In the present study, we aimed to map patient preferences, attitudes toward treatment, and quality of life to identify the predictors of non-adherence to teriflunomide. Methods: This was a single-arm, non-interventional, multicenter study (Czech Act 378/2007 Coll.) consisting of three visits: the first at treatment initiation (teriflunomide 14 mg), and then after 3 and 9 months of therapy. We enrolled both DMT-naïve and patients who had undergone a DMT diagnosed with a clinically isolated syndrome (CIS) or relapsing-remitting multiple sclerosis (RRMS). The functional status and MS activity were estimated using the Expanded Disability Status Scale (EDSS) and annualized relapse rate (ARR); the quality of life via the Multiple Sclerosis Impact Scale (MSIS-29); the medication adherence with the Morisky Medication Adherence Scale (MMAS-8); the confidence in the ability to take medications by the Self-Efficacy for Appropriate Medication Score (SEAMS); and the attitude to the therapy via the Beliefs about Medicines Questionnaire (BMQ). After nine months of therapy, we predicted the adherence to teriflunomide (MMAS-8) by fitting a multivariate ordinal logistic model with EDSS changes, gender, previous DMT, MSIS-29, BMQ, and SEAMS as the explanatory variables. Results: Between 2018 and 2019, 114 patients were enrolled at 10 sites in the Czech Republic. The mean age was 41.2 years, 64.8% were diagnosed with a CIS, 52.4% were DMT-naïve, and 98.1% of patients preferred an oral administration at the baseline. The mean EDSS baseline was 1.97 and remained constant during the 9 months of therapy. The ARR baseline was 0.72 and dropped to 0.19 and 0.15 after 3 and 9 months, respectively. Despite a more than 4-fold higher ARR baseline, the treatment-naïve patients achieved an ARR at 9 months comparable with those previously treated. There were ten non-serious adverse reactions. After nine months of teriflunomide therapy, 63.3%, 21.2%, and 15.4% of patients had a high, medium, and low adherence, respectively, as per the MMAS-8; 100% of patients preferred an oral administration. The SEAMS score (odds ratio (OR) = 0.91; p = 0.013) and previous DMT (OR = 4.28; p = 0.005) were the only significant predictors of non-adherence. The disability, the quality of life, and beliefs about medicines had no measurable effect on adherence. Conclusion: After nine months of teriflunomide therapy, both the disability and quality of life remained stable; the relapse rate significantly decreased, 63.3% of patients had a high adherence, and 100% of patients preferred an oral administration. A low adherence was associated with previous DMT experiences and a low self-efficacy for the appropriate medication (i.e., the confidence in one's ability to take medication correctly).

Abstract
Background Increased understanding of adherence may facilitate optimal targeting of interventions. Objective To utilize group-based trajectory modeling (GBTM) to understand longitudinal patterns of adherence and factors associated with non-adherence in patients with multiple sclerosis (MS) newly-initiating once-/twice-daily oral disease-modifying therapy (DMT) (fingolimod, dimethyl fumarate, or teriflunomide). Methods Commercial plan data were analyzed using proportion of days covered (PDC) to evaluate factors associated with non-adherence. GBTM clustered patient subgroups with similar longitudinal patterns of adherence measured by monthly PDC (≥80%) and multinomial logistic regression identified factors associated with adherence trajectory subgroups. Results Among 7689 patients, 39.5% were non-adherent to once-/twice-daily oral DMTs. Characteristics associated with non-adherence (PDC<80%) included younger age, female, depression or migraine, switching during follow-up, more frequent dosing, relapse, and absence of magnetic resonance imaging. GBTM elucidated three adherence subgroups: Immediately Non-Adherent (14.9%); Gradually Non-Adherent (19.5%), and Adherent (65.6%). Additional factors associated with adherence (i.e. region, chronic lung disease) were identified and factors differed among trajectory subgroups. Conclusion These analyses confirmed that a significant proportion of patients with MS are non-adherent to once-/twice-daily oral DMTs. Unique patterns of non-adherence and factors associated with patterns of adherence emerged. The approach demonstrated how quantitative trajectories can help clinicians develop tailored interventions.

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. JMIR Form Res 2022; 6:e31972. [PMID: 35285806 PMCID: PMC8929528 DOI: 10.2196/31972] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Revised: 12/09/2021] [Accepted: 12/22/2021] [Indexed: 11/13/2022] Open
Abstract
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.

Abstract
Multiple sclerosis (MS) is a chronic, autoimmune, demyelinating disease of the central nervous system (CNS). MS is an incurable disease. The goal of disease-modifying therapies (DMT) is to slow the progression of the disease, prevent relapses and increase the patient’s overall quality of life. According to the World Health Organisation definition, adherence means the extent to which a person’s medication-taking behaviour corresponds with the agreed upon treatment recommendations from a healthcare provider. Accurate adherence is necessary for efficient treatment. Non-adherence is related to unsuccessful treatments, the risk of relapses and increased healthcare costs. The aim of this study is to present the main factors relating to non-adherence in MS patients.

Abstract
Aim: To evaluate adherence, healthcare resource utilization (HRU) and costs for glatiramer acetate (GA; injectable), dimethyl fumarate (oral) and teriflunomide (oral) in relapsing multiple sclerosis. Patients & methods: Retrospective analyses of a claims database. Results: Teriflunomide patients were older with more co-morbidities and fewer relapses versus GA and dimethyl fumarate. GA patients were mostly disease-modifying therapies (DMTs)-treatment naive. Treatment adherence was 61-70%. All DMTs reduced HRU versus pre-index. Costs were comparable across cohorts. High adherence reduced hospitalizations and several costs versus low adherers. Conclusion: Adherence rates were high and comparable with all DMTs. Similar (and high) reductions in HRU and costs occurred with all DMTs. High adherence improved economic outcomes versus low adherence. Thus, investing in adherence improvement is beneficial to improve outcomes in relapsing multiple sclerosis.

Abstract
People with multiple sclerosis (MS) face challenges adhering to disease-modifying drug (DMD) treatment. Poor adherence to treatment reduces its clinical effectiveness which can adversely impact disease progression, MS-related hospitalisation, and mortality rates. Understanding the barriers to adherence is essential to addressing these issues in clinical practice and a consolidation of the literature had not yet been carried out. A systematic search was carried out using the electronic databases PsycINFO, and PubMed (Medline) using the search terms treatment compliance or treatment adherence and multiple sclerosis or MS. Studies included adults, with a diagnosis of relapsing–remitting MS (RRMS) (sample > 80% RRMS), taking a DMD. The studies used an adequate measurement of treatment adherence and analysed possible factors associated with adherence. A total of 349 studies were retrieved, of which 24 were considered eligible for inclusion. Overall adherence rates of the included studies ranged from 52 to 92.8%. Narrative synthesis revealed the most prevalent factors associated with adherence were age, gender, depression, cognition, treatment satisfaction, injection-site reactions, and injection anxiety. There was contradictory evidence for disability in association with treatment adherence. The findings should be used to inform the development of targeted patient support programs which improve treatment compliance. The review also highlights the opportunities for advancing research into treatment adherence in MS.

Abstract
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.

Abstract
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. Allan holds advisory board and consulting positions with Merck and advisory board positions for Bristol Myers Squibb and Novartis, for which Monash Institute of Neurological Diseases receives consulting fees.

Electronic pill bottles to monitor and promote medication adherence for people with multiple sclerosis: A randomized, virtual clinical trial. J Neurol Sci 2021; 428:117612. [PMID: 34392138 DOI: 10.1016/j.jns.2021.117612] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2021] [Revised: 07/25/2021] [Accepted: 08/04/2021] [Indexed: 11/19/2022]
Abstract
OBJECTIVE We perform a randomized trial to test the impact of electronic pill bottles with audiovisual reminders on oral disease modifying therapy (DMT) adherence in people with MS (PwMS). METHODS Adults with multiple sclerosis (MS) taking an oral DMT were randomized 1:1 for 90 days to remote smartphone app- and pill bottle-based (a) adherence monitoring, or (b) adherence monitoring with audiovisual medication reminders. Optimal adherence was defined as the proportion of doses taken ±3 h of the scheduled time. Numbers of missed pills and pills taken early, on time, late, and extra were recorded. A multivariable regression model tested possible associations between optimal adherence and age, MS duration, cognitive functioning, and number of daily prescription pills. RESULTS 85 participants (66 female; mean age 44.9 years) took dimethyl/diroximel fumarate (n = 49), fingolimod (n = 26), or teriflunomide (n = 10). Optimal adherence was on average higher in the monitoring with reminders arm (71.4%) than the monitoring only arm (61.6%; p = 0.033). In a multivariable model, optimal adherence was less likely in younger participants (p < 0.001) and those taking more daily prescription pills (p < 0.001). In the monitoring only arm, 4.0% of doses were taken early, 61.6% on time, 5.6% late, 4.4% in excess, and 24.4% were missed. In the reminders arm, these proportions were 3.4%, 71.4%, 3.7%, 8.7%, and 12.8%, respectively. CONCLUSION We map real-world oral DMT adherence patterns using mHealth technology. PwMS who received medication reminders had higher optimal adherence. Nonadherence was more nuanced than simply missing pills. Developing strategies to improve adherence remains important in longitudinal MS care.

Abstract
Background Treatment-emergent adverse events (TEAEs) that occur close to treatment initiation may negatively affect overall tolerability and adherence. It is important to develop a clear understanding of potential early TEAEs after initiating treatment with cladribine tablets. Objective To identify TEAEs that begin early in the course of treatment in patients enrolled in CLARITY and ORACLE-MS studies. Methods This post hoc analysis of CLARITY and ORACLE-MS safety populations assessed the incidence of TEAEs, serious TEAEs, drug-related TEAEs, and TEAEs leading to discontinuation in patients receiving cladribine tablets or placebo within 2, 6, and 12 weeks after treatment initiation. Results By Week 12, 61.3% of patients treated with cladribine tablets 3.5 mg/kg and 55.2% treated with placebo experienced a TEAE. More patients receiving cladribine tablets versus placebo experienced a drug-related TEAE by Week 12 (34.7% vs. 23.2%). The most common TEAEs reported with cladribine tablets were: headache (7.2%), lymphopenia (6.8%), and nausea (6.0%). Patients receiving cladribine tablets and placebo reported similar proportions of serious TEAEs (2.2% vs. 1.7%) and TEAEs leading to treatment discontinuation (1.6% vs. 1.4%). Conclusion Cladribine tablets were well tolerated during the first 12 weeks as evidenced by a low incidence of TEAEs leading to treatment discontinuation.

Abstract
BACKGROUND: For multiple sclerosis (MS) patients taking disease-modifying therapies (DMTs), adherence to treatment is a key component of achieving beneficial outcomes, such as delayed disease progression and the reduction and prevention of symptoms and relapses. OBJECTIVES: The aim of this study was to assess the impact of a claims-based measure of MS disease severity on DMT adherence in a one-year study period. METHODS: Patients were identified from Humana Medicare Advantage claims data from January 1, 2013 to December 31, 2015. Patients over the age of 18 with at least 12 months of continuous enrollment and > 1 outpatient MS visit with DMT use prior to the index date were included. Patients who switched DMT type (oral, platform, IV) during the study period were excluded. Medication possession ratios (MPR) for DMTs were calculated from pharmacy and medical claims over 12 months of claims data, and a previously developed claims algorithm was used to determine MS disease severity. Patients with MPRs of 0.8 or higher were considered adherent to DMT treatment. Multivariable logistic regression was used to evaluate the association of MS disease severity, gender, DMT type, and age category with DMT adherence. RESULTS: The study population of 3,347 patients had an average MPR of 84.7 (75% were classified as adherent). Multivariable logistic analysis demonstrated that compared to the 18-45 age group, the 46-64 and 65+ age groups were 1.33 (OR: 1.33 [95% CI 1.08-1.64]) and 1.55 (OR: 1.55, [95% CI 1.18-2.05]) times more likely to be adherent. Patients with a high level of MS disease severity were 53% (OR: 0.47, [95% CI 0.36-0.62]) less likely to be adherent compared to those with low MS disease severity. No significant difference was identified for gender or DMT type (oral, platform, or IV). CONCLUSIONS: Increased age and lower MS disease severity were associated with better DMT adherence. MS disease severity should be considered when assessing risk for low DMT adherence. DISCLOSURES: No funding supported this project. The authors have nothing to disclose. Preliminary results were previously presented virtually at AMCP Annual 2020 in April 2020.

Abstract
Growing concern about neurodegenerative diseases is becoming a global issue. It is estimated that not only will their prevalence increase but also morbidity and health burden will be concerning. Scientists, researchers and clinicians share the responsibility of raising the awareness and knowledge about the restricting and handicapping health restrains related to these diseases. Multiple Sclerosis (MS), as one of the prevalent autoimmune diseases, is characterized by abnormal regulation of the immune system that periodically attacks parts of the nervous system; brain and spinal cord. Symptoms and impairments include weakness, numbness, visual problems, tingling pain that are quietly variable among patients. Amyotrophic Lateral Sclerosis (ALS) is another neurodegenerative disease that is characterized by the degeneration of motor neurons in the brain and spinal cord. Unlike MS, symptoms begin with muscle weakness and progress to affect speech, swallowing and finally breathing. Despite the major differences between MS and ALS, misdiagnosis is still influencing disease prognosis and patient's quality of life. Diagnosis depends on obtaining a careful history and neurological examination as well as the use of Magnetic Resonance Imaging (MRI), which are considered challenging and depend on the current disease status in individuals. Fortunately, a myriad of treatments is available now for MS. Most of the cases are steroid responsive. Disease modifying therapy is amongst the most important set of treatments. In ALS, few medications that slow down disease progression are present. The aim of this paper is to summarize what has been globally known and practiced about MS and ALS, as they are currently classified as important growing key players among autoimmune diseases. In terms of treatments, it is concluded that special efforts and input should be directed towards repurposing of older drugs and on stem cells trials. As for ALS, it is highlighted that supportive measurements and supplementary treatments remain essentially needed for ALS patients and their families. On the other hand, it is noteworthy to clarify that the patient-doctor communication is relatively a cornerstone in selecting the best treatment for each MS patient.

Abstract
OBJECTIVES The aim of this study was to examine the indirect burden of employed multiple sclerosis (MS) patients initiating disease-modifying therapies (DMTs) in the US. METHODS DMT-treated MS patients (DMT users) and direct-matched controls without MS (1:3) were captured using the IBM MarketScan Commercial Claims and Encounters Database and the Health and Productivity Management Database between 1 January 2009 and 1 January 2017. DMT users were also stratified by route of administration. Time loss and costs from absenteeism, short-term disability, and long-term disability were assessed for DMT users and matched controls. RESULTS A total of 3022 DMT users were matched to 9066 controls. Compared with injectable DMT users, oral DMT users took twice as long to initiate therapy but had numerically lower absenteeism costs and significantly lower long-term disability costs in the first year after DMT initiation. The mean (standard deviation) indirect costs of absenteeism, short-term disability, and long-term disability were US$6474 (US$6779), US$2368 (US$5777), and US$280 (US$2578), respectively, for DMT users and US$4468 (US$3814), US$328 (US$1950), and US$36 (US$938), respectively, for controls in the first year (all p < 0.001). CONCLUSIONS Employed DMT users in the US incurred incremental increased indirect burden ($2007 in absenteeism, $2040 in short-term disability, and $244 in long-term disability) compared with matched controls. Despite evidence of delays in treatment initiation, oral DMT users had evidence of reduced work loss compared with injectable users, suggesting that open access to all treatment options may reduce the indirect burden of MS. Additional research into the impact of route of administration on the burden of long-term disability among MS patients is needed.

Abstract
Objectives To explore adherence, persistence, and treatment patterns in patients with multiple sclerosis (MS) in Finland treated with disease‐modifying therapies (DMTs) for active MS in 2005‐2018. Materials and Methods The study cohort was identified using the Drug Prescription Register of Social Insurance Institute, Finland. All patients had at least one prescription of glatiramer acetate (GA), beta‐interferons, teriflunomide, or delayed‐release dimethyl fumarate (DMF). Adherence was calculated using proportion of days covered (PDC) (cutoff ≥0.8). Time to non‐persistence was calculated by the number of days on index DMT treatment before the first treatment gap (≥90 days) or switch and analyzed with time‐to‐event methodology. Results The cohort included 7474 MS patients (72.2% female; mean age 38.9 years). Treatment switches were steady over 2005‐2012, peaked in 2015. PDC means (standard deviations) were GA, 0.87 (0.17); beta‐interferons, 0.88 (0.15); DMF, 0.89 (0.14); teriflunomide, 0.93 (0.10). Adherence frequencies were GA, 78.4%; beta‐interferons, 81.3%; DMF, 86.9%; teriflunomide, 91.7%. Logistic regression showed that age group, DMT and the starting year, sex, and hospital district independently affected adherence. Patients receiving teriflunomide and DMF, males, and older patients were more likely to persist on treatment. There was no difference in persistence between patients prescribed teriflunomide and DMF, or between GA and beta‐interferons. Conclusions Oral DMTs had greater adherence and persistence than injectable DMTs.

Abstract
PURPOSE Although all disease-modifying therapies (DMTs) reduce risk of relapse in multiple sclerosis (MS), many factors, including route of administration, influence selection of first-line DMT. Knowledge of real-world treatment patterns and effectiveness in reducing relapses across DMTs is important to understanding factors influencing this choice. This study sought to describe treatment patterns and relapses among newly treated adults with MS and by DMT route of administration (oral, injectable, and infusion). METHODS IBM MarketScan research databases were used to identify MS adults newly initiating DMTs (index event) from January 1, 2011-April 1, 2016, who had 12 months of continuous preindex and postindex medical and pharmacy benefits. Newly treated patients were those with ≥2 nondiagnostic claims with an International Classification of Diseases, Ninth Revision, Clinical Modification (340) or Tenth Revision, Clinical Modification (G35) code and no DMT prescription claims in the 12 months' preindex. Persistence and adherence were measured from index until the earliest of ≥60 days without DMT, switching DMTs, or end of follow-up. Relapses were defined using a validated claims-based algorithm and measured in the 12-month preindex and postindex periods. Regression analysis adjusting for patient characteristics and prior relapses was used to determine the association between DMT route of administration and odds of 12-month persistence, odds of postindex relapse, and number of postindex relapses. FINDINGS Of 9378 newly treated MS patients meeting inclusion criteria; average age was 46.7 years, and 73.3% were female. Most patients initiated an injectable (65.5%) or oral (26.1%) DMT. Relapses decreased markedly from preindex to postindex (32.9%-24.0%), which was highest among oral users (35.8%-21.6%). Patients with no (vs ≥3) relapses preindex were more likely to be relapse free postindex (81.6% vs 31.4%). Nonpersistence (39.1% overall) was lowest among oral users (33.4%) and higher among those with versus without a postindex relapse (50.6% vs 35.5%). Patients initiating oral versus injectable agents were more likely to be persistent at 12 months (odds ratio [OR], 1.45; p < 0.0001) and less likely to relapse (OR, 0.75; p < 0.0001) postindex. Switches were uncommon (~10%) across cohorts. Preindex relapses were associated with increased odds of postindex relapses (OR, 1.73; p < 0.0001) but not with odds of persistence at 12 months. IMPLICATIONS The 12-month nonpersistence rate was high among all MS patients but lower among oral users. Oral users were also less likely to relapse postindex. Despite the effectiveness of DMTs in reducing relapses, the low persistence, lack of switching to a new DMT, and continued relapses highlight an unmet need in the MS treatment landscape.

Abstract
BACKGROUND Oral fingolimod is convenient to use than injectable disease modifying agents (DMAs) in patients with multiple sclerosis (MS). However, the existing literature regarding the comparative adherence trajectories between oral fingolimod and injectable DMAs is limited. OBJECTIVE To compare the adherence trajectories between oral DMA, fingolimod, and injectable DMAs in patients with MS. METHODS A retrospective longitudinal study was conducted using adults (≥18 years) with MS (ICD-9-CM: 340 and a DMA prescription) from the IBM MarketScan Commercial Claims and Encounters Database between 2010 and 2012. Patients were grouped into oral fingolimod or injectable DMA users based on the index DMA among patients with MS. The annual DMA adherence trajectories, based on the proportion of days covered (PDC), were examined using group-based trajectory modeling (GBTM) during the one-year follow-up period after treatment initiation. Multivariable multinomial logistic regression using stabilized inverse probability treatment weights (IPTW) was performed to assess the association between the DMA route of administration (Oral vs Injectable) and the adherence trajectory groups. The balance of covariates between oral and injectable DMAs before and after IPTW was checked against a standardized difference threshold of 0.25. RESULTS The study cohort consisted of 1,700 MS patients who were initiated with oral (15.8%) or injectable (84.2%) DMAs between 2010 and 2012. The adherence rates (PDC≥0.8) in oral fingolimod and injectable DMA users were found to be 64.7% and 50.8%, respectively. The GBTM grouped individuals in the study cohort into three adherence trajectories - rapid discontinuers (23.5%), complete adherers (49.9%), and slow decliners (26.6%). The multinomial logistic regression model with stabilized IPTW revealed that oral fingolimod users had higher odds to be a complete adherer (adjusted odds ratio [AOR]: 2.78, 95% CI: 1.85-4.16) or a slow discontinuer (AOR: 2.62, 95% CI: 1.70-4.05) than injectable DMA users. CONCLUSIONS Oral DMA fingolimod was associated with better adherence than injectable DMAs across group-based trajectories. Further research is warranted to evaluate the adherence trajectories with newer oral DMAs introduced in the last decade for MS.

Abstract
Background Positive psychology (PP) uses targeted activities to increase the frequency and intensity of positive feelings and may improve overall well-being in medically ill populations. In this phase 1 randomized controlled trial, we examined the feasibility, acceptability, and potential impact of a 5-week, telephone-delivered PP intervention for individuals with multiple sclerosis (MS). Methods Participants were randomized 1:1 to a 5-week at-home PP intervention or a waitlist control condition. Participants engaged in weekly telephone calls with a study trainer and completed one PP exercise, such as recalling a past success, each week. Feasibility was determined by the number of sessions completed, and acceptability was assessed by weekly postexercise participant ratings of ease and utility. Efficacy was explored by examining between-group differences in changes from baseline on psychological variables, health-related quality of life, and self-reported functional activities at 5 and 10 weeks. Results Of 30 patients enrolled in the study, 28 (93%) completed all exercises. Ease scores ranged from 7.7 to 8.7 of 10 and utility scores ranged from 8.2 to 8.7 of 10. The PP intervention was associated with significantly greater increases (P < .05) in positive affect, optimism, state and trait anxiety, general health, and resilience in the intervention group versus the control group. Approximately half of the PP participants maintained at least 50% of the improvement at 10 weeks. Conclusions This 5-week, telephone-based PP intervention was feasible and acceptable to individuals with MS. Larger randomized controlled trials are warranted to further investigate the utility of this intervention to improve well-being and other health outcomes in MS.

Abstract
BACKGROUND Nonadherence to disease-modifying drugs (DMDs) for multiple sclerosis (MS) is associated with poorer clinical outcomes, including higher rates of relapse and disease progression, and higher medical resource use. A systematic review and quantification of adherence and persistence with oral DMDs would help clarify the extent of nonadherence and nonpersistence in patients with MS to help prescribers make informed treatment plans and optimize patient care. The objectives were to: 1) conduct a systematic literature review to assess the availability and variability of oral DMD adherence and/or persistence rates across 'real-world' data sources; and 2) conduct meta-analyses of the rates of adherence and persistence for once- and twice-daily oral DMDs in patients with MS using real-world data. METHODS A systematic review of studies published between January 2010 and April 2018 in the PubMed database was performed. Only studies assessing once- and twice-daily oral DMDs were available for inclusion in the analysis. Study quality was evaluated using a modified version of the Newcastle-Ottawa Scale, a tool for assessing quality of observational studies. The random effects model evaluated pooled summary estimates of nonadherence. RESULTS From 510 abstracts, 31 studies comprising 16,398 patients with MS treated with daily oral DMDs were included. Overall 1-year mean medication possession ratio (MPR; n = 4 studies) was 83.3% (95% confidence interval [CI] 74.5-92.1%) and proportion of days covered (PDC; n = 4 studies) was 76.5% (95% CI 72.0-81.1%). Pooled 1-year MPR ≥80% adherence (n = 6) was 78.5% (95% CI 63.5-88.5%) and PDC ≥80% (n = 5 studies) was 71.8% (95% CI 59.1-81.9%). Pooled 1-year discontinuation (n = 20) was 25.4% (95% CI 21.6-29.7%). CONCLUSIONS Approximately one in five patients with MS do not adhere to, and one in four discontinue, daily oral DMDs before 1 year. Opportunities to improve adherence and ultimately patient outcomes, such as patient education, medication support/reminders, simplified dosing regimens, and reducing administration or monitoring requirements, remain. Implementation of efforts to improve adherence are essential to improving care of patients with MS.

Abstract
BACKGROUND Multiple sclerosis (MS) is a chronic, inflammatory, central nervous system demyelinating disease that requires long-term use of disease-modifying therapies (DMT). Patient adherence to DMT is key in reducing the inflammation that leads to relapses and neurodegeneration. Dimethyl fumarate (DMF) poses unique challenges to adherence including being the only twice-daily dosing DMT. Previous research suggests there are direct roles that providers play on improving their patients' adherence rates, such as focusing on the patient-provider relationship, helping put the patient at ease so that they feel understood and respected. Also, route of administration affects adherence in other chronic healthcare conditions. However, the issue of adherence to DMT in MS is more complex than just route of administration, with adverse effects being the main predictor of adherence. OBJECTIVES (1) To define various patient specific factors (e.g. fatigue and mood disorders) that affect adherence with DMF and (2) to understand how patients' perceptions of treatment satisfaction (such as effectiveness, convenience, side effects and global satisfaction) and DMFs impact on quality of life (such as social support, activities of daily living, coping) influence adherence. METHODS Our study was a prospective, observational measurement of adherence to treatment with DMF in MS patients over 52 weeks. Twenty-five out of thirty-five patients enrolled completed the study. Adverse event (AE) data was reviewed on all participants. RESULTS Adherence rates correlated with patient's perceived effectiveness (0.25, p < 0.023) and the level of bothersome symptoms the patient experienced (0.45, p < 0.0001). The majority of new AE onset was reported within 12 weeks of DMF initiation. This is consistent with previously published data with DMF use. CONCLUSION Adherence rates are an important factor to be considered when starting patients on DMT. DMF creates its own barriers to adherence with our study highlighting some, including twice-daily dosing and AEs experienced following treatment initiation. Healthcare providers should be aware of these barriers prior to treatment initiation and counsel patients appropriately.

The Impact of Patient Support Programs on Adherence to Disease-Modifying Therapies of Patients with Relapsing-Remitting Multiple Sclerosis in Germany: A Non-Interventional, Prospective Study. Adv Ther 2020; 37:2999-3009. [PMID: 32333326 PMCID: PMC7467433 DOI: 10.1007/s12325-020-01349-3] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2020] [Indexed: 10/25/2022]
Abstract
INTRODUCTION Disease-modifying therapies (DMTs) in multiple sclerosis (MS) are chronic therapies, and patients are likely to face challenges in adhering to DMT dosing regimens over time. DMT manufacturers offer patient support programs (PSPs) to increase adherence. PSPs are managed offerings typically encompassing nurse services, phone services, online resources, or mobile offerings. This study evaluated whether PSPs have a positive impact on adherence to DMTs among patients with mild-to-moderate relapsing-remitting multiple sclerosis (RRMS) in Germany, independent of the treatment duration on DMT. METHODS This was a non-interventional, prospective, cross-sectional, multi-center study with patient-reported outcomes. Patients reported their DMT adherence using patient adherence questionnaires at four visits during an observation period of 24 weeks; PSP participation for this period was reported at the last visit. The primary objective was to evaluate the impact of PSPs on adherence across different DMTs by comparing patients with PSP participation versus no participation; adherence was defined as not missing a single dose of DMT. RESULTS One hundred eighty-four patients were analyzed (mean age: 44.6 years; 73.4% female; mean time on DMT: 7.2 years). Adherence across DMTs was significantly higher for PSP participants (92.9%) compared with non-participants (61.8%) (P = 0.0197). The observed rate of PSP participation (7.6%) was significantly lower than reported in earlier studies (P < 0.0001); PSP awareness among patients analyzed was low (22.3%). CONCLUSION We consider this study to have shown that PSPs have a positive impact on adherence to DMTs in MS, independent of the treatment duration on DMT. The majority of PSP participants also believe in this positive effect. PSP participation and patient awareness were low, and real-world adherence levels were found to be higher with self-injectable DMTs than with oral DMTs. In summary, physicians should actively advise patients with MS to participate in PSPs and, together with their patients, consider achievable real-world adherence under different DMTs when deciding MS treatment strategies.

Abstract
BACKGROUND Persons with multiple sclerosis (PwMS) are disproportionately burdened by depression compared to the general population. While several factors associated with depression and depression severity in PwMS have been identified, a prediction model for depression risk has not been developed. In addition, it is unknown if depression-related genetic variants, including Apolipoprotein E (APOE), would be informative for predicting depression in PwMS. OBJECTIVE To develop a depression prediction model for PwMS who did not have a history of depression prior MS onset. METHODS The study population included 917 non-Hispanic white PwMS. An optimized multivariable Cox proportional hazards model for time to depression was generated using non-genetic variables, to which APOE and a depression-related genetic risk score were included. RESULTS Having a mother who had a history of depression, having obstructive pulmonary disease, obesity and other physical disorders at MS onset, and affect-related symptoms at MS onset predicted depression risk (hazards ratios (HRs): 1.6-2.3). Genetic variables improved the prediction model's performance. APOE ε4/ε4 and ε2/x conferred increased (HR = 2.5, p = 0.026) and decreased (HR = 0.65, p = 0.046) depression risk, respectively. CONCLUSION We present a prediction model aligned with The Precision Medicine Initiative, which integrates genetic and non-genetic predictors to inform depression risk stratification after MS onset.

Abstract
BACKGROUND Adherence to specialty and nonspecialty medications is often calculated using pharmacy claims data. However, specialty medication regimens are complex and may require periods of intentional gaps in therapy. Common adherence calculations are insufficient in identifying reasons for gaps in therapy. Because adherence reporting is a growing measure of quality care for specialty pharmacy accreditation and payer and manufacturer contracts, a better understanding of the rates and reasons for nonadherence within a specialty population is needed. OBJECTIVE To identify rates and reasons for misidentified and true nonadherence in patients who are prescribed specialty medications. METHODS A single center, retrospective cohort study was conducted using pharmacy claims data between March 2017 and February 2018. Medication adherence was calculated using proportion of days covered (PDC). Electronic medical records of a random 10% sample of nonadherent patients (PDC < 80%) were manually reviewed to identify reasons for nonadherence. Patients were then classified as either (a) misidentified as nonadherent (i.e., a provider-directed discontinuation or disruption of treatment that varies from the prescribed administration schedule or transfer of the prescription to an external pharmacy) or (b) truly nonadherent (discontinuation or disruption of treatment that varies from the prescribed administration instruction that is not directed or recommended by the provider or health care team). RESULTS Of the 7,488 included prescription records from 18 specialty areas, 1,059 met criteria for nonadherence. 105 prescription records (representing 105 unique patients) were manually reviewed; most of these patients (58%) were truly nonadherent, driven by inability to contact patients for refills (59%). However, 40% were misidentified as nonadherent, most due to provider-directed medication holding (69%). Two percent of patients were nonadherent for unknown reasons. CONCLUSIONS Many patients classified as nonadherent based on pharmacy claims experienced gaps in therapy due to medically appropriate reasons. Methods to better measure and identify true nonadherence are needed to efficiently and adequately affect specialty medication adherence behavior.

Assessment of Medication Adherence Using a Medical App Among Patients With Multiple Sclerosis Treated With Interferon Beta-1b: Pilot Digital Observational Study (PROmyBETAapp). J Med Internet Res 2019; 21:e14373. [PMID: 31359863 PMCID: PMC6690164 DOI: 10.2196/14373] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2019] [Revised: 06/04/2019] [Accepted: 06/15/2019] [Indexed: 12/18/2022] Open
Abstract
Background Accurate measurement of medication adherence using classical observational studies typically depends on patient self-reporting and is often costly and slow. In contrast, digital observational studies that collect data directly from the patient may pose minimal burden to patients while facilitating accurate, timely, and cost-efficient collection of real-world data. In Germany, ~80% of patients with multiple sclerosis (MS) treated with interferon beta 1b (Betaferon) use an electronic autoinjector (BETACONNECT), which automatically records every injection. Patients may also choose to use a medical app (myBETAapp) to document injection data and their well-being (using a “wellness tracker” feature). Objective The goal of this pilot study was to establish a digital study process that allows the collection of medication usage data and to assess medication usage among patients with MS treated with interferon beta-1b who use myBETAapp. Methods The PROmyBETAapp digital observational study was a mixed prospective and retrospective, noninterventional, cohort study conducted among users of myBETAapp in Germany (as of December 2017: registered accounts N=1334; actively used accounts N=522). Between September and December 2017, users received two invitations on their app asking them to participate. Interested patients were provided detailed information and completed an electronic consent process. Data from consenting patients’ devices were collected retrospectively starting from the first day of usage if historical data were available in the database and collected prospectively following consent attainment. In total, 6 months of data on medication usage behavior were collected along with 3 months of wellness tracker data. Descriptive statistics were used to analyze persistence, compliance, and adherence to therapy. Results Of the 1334 registered accounts, 96 patients (7.2%) provided informed consent to participate in the study. Of these, one patient withdrew consent later. For another patient, injection data could not be recorded during the study period. Follow-up of the remaining 94 patients ended in May 2018. The mean age of participants was 46.6 years, and 50 (53%) were female. Over the 6-month study period, persistence with myBETAapp usage was 96% (90/94), mean compliance was 94% of injections completed, and adherence (persistence and ≥80% compliance) was 89% (84/94). There was no apparent difference between male and female participants and no trend across age groups. The wellness tracker was used by 21% of participants (20/94), with a mean of 3.1 entries per user. Conclusions This study provides important information on medication usage among patients with MS treated with interferon beta-1b and on consenting behavior of patients in digital studies. In future studies, this approach may allow patients’ feedback to be rapidly implemented in existing digital solutions.

Abstract
Multiple sclerosis treatment faces tremendous changes owing to the approval of new medications, some of which are available as oral formulations. Until now, the four orally available medications, fingolimod, dimethylfumarate (BG-12), teriflunomide, and cladribine have received market authorization, whereas laquinimod is still under development. Fingolimod is a sphingosine-1-phosphate inhibitor, which is typically used as escalation therapy and leads to up to 60% reduction of the annualized relapse rate, but might also have neuroprotective properties. In addition, there are three more specific S1P agonists in late stages of development: siponimod, ponesimod, and ozanimod. Dimethylfumarate has immunomodulatory and cytoprotective functions and is used as baseline therapy. Teriflunomide, the active metabolite of the rheumatoid arthritis medication leflunomide, targets the dihydroorotate dehydrogenase, thus inhibiting the proliferation of lymphocytes by depletion of pyrimidines. Here we will review the mechanisms of action, clinical trial data, as well as data about safety and tolerability of the compounds.

Abstract
PURPOSE Adherence to disease-modifying treatments is essential in order to maximize the beneficial effects of treatment for multiple sclerosis (MS). There are numerous treatments that have been approved. Treatment selection is essential in patient adherence. In addition, patient preference plays an increasingly significant role in treatment decision-making. This study aims to evaluate the degree of adherence, along with other variables that may influence this adherence, in Spain. METHODS A cross-sectional study was conducted with 157 MS patients with disease-modifying treatments. Adherence was assessed using the Morisky Green scale, and other related factors were measured using a questionnaire that addressed demographics, disease characteristics, global perception of pathology, impact of medication on patient's life, and treatment decision-making. RESULTS The adherence rate was 71% and was associated with the following variables: older age, more treatments received, time to diagnosis 5-10 years, absence of exacerbations, better cognitive status, being married/in a union, clear information about the disease, and higher treatment satisfaction. The main cause for non-compliance was forgetfulness (27%). CONCLUSION The adherence rate is acceptable. It is widely known that treatment satisfaction is related to adherence. In our study, patients' level of satisfaction was higher with oral treatments. However, oral administration showed a greater lack of adherence. The main cause of lack of adherence was forgetfulness. In relation to other variables, cognitive status and family support showed a correlation with treatment adherence.

Abstract
INTRODUCTION Despite the increasing age of the multiple sclerosis (MS) patient population, data are lacking on MS patients in later life. This retrospective study investigated treatment patterns, healthcare resource utilization (HCRU), and healthcare costs (HCCs) for patients enrolled in Medicare, in relation to disease-modifying therapy (DMT) and corticosteroid treatment as a marker for relapse. METHODS Medical and pharmacy claims between January 1, 2010 and July 31, 2015 identified MS patients. The anchor date was defined as the most recent MS claim. Analyses were performed on claims in the 12-month baseline period before the anchor date. Outcomes were stratified by DMT use and number (0, 1, or ≥ 2) of corticosteroid treatments. RESULTS Among Medicare MS patients (n = 7072; mean age 57 years), 66% received DMT during the baseline period; 31% had 1 claim and 16% had ≥ 2 claims for corticosteroids. Compared with patients not receiving DMT, patients on DMT were less likely to receive corticosteroids (39% vs 62%) and had fewer all-cause hospitalization episodes and ER visits. DMT use was associated with lower HCRU but higher HCCs in patients both with and without corticosteroid treatment. DMT switching rates were low, both among patients with no corticosteroid (5.6%) and patients with 1 (9.3%) or ≥ 2 (11.1%) corticosteroid treatments. DMT switches were most frequently from an injectable to an oral therapy. CONCLUSION In Medicare patients with MS, DMT use was associated with higher HCCs but lower HCRU, indicative of better health outcomes; however, low DMT switching rates may be an indicator of possible clinical inertia.

Abstract
OBJECTIVE To examine persistence and adherence to the oral disease-modifying therapies (DMTs) for multiple sclerosis (MS). METHODS Population-based health administrative databases in British Columbia, Canada were accessed to identify all individuals filling an oral DMT prescription for MS (fingolimod, dimethyl fumarate, teriflunomide) between January 2011 and December 2015. Predictors of persistence and adherence at 6 and 12 months were assessed using logistic regression, with estimates expressed as adjusted odds ratios (aORs), and 95% confidence intervals (CIs). RESULTS Of 858 individuals with ≥6 months of follow-up, the mean age at first prescription was 43.0 (SD:10.3) years; 74.2% were women. By 6 months 11.0% (94/858) had discontinued their initial oral DMT; by 12 months the proportion was 19.6% (113/577). Over 6 and 12 months, among those persisting with their oral DMT, 82.5% (630/764) and 81.7% (379/464) exhibited optimal adherence (proportion of days covered ≥80%). Age, sex, calendar year and comorbidity were not associated with persistence or adherence. Individuals with higher neighbourhood-level socioeconomic status had higher odds of discontinuation within 6 months (aOR = 2.2; 95%CI:1.3-3.7). Those who had previously used another DMT had higher odds of optimal adherence (6 months aOR = 2.4;95%CI:1.6-3.6, and 12 months aOR = 2.4; 95%CI:1.5-3.9). CONCLUSION Approximately 1 in 10 individuals discontinued their first oral DMT within 6 months, and 1 in 5 did so within one year. However, among those who did continue drug, a high proportion (>80%) exhibited optimal adherence. Predictors of persistence or adherence with immediate practical application were lacking; this highlights the challenges in optimizing drug therapy.

Abstract
BACKGROUND Shared decision making (SDM) and adherence to treatment are an integral part of multiple sclerosis (MS) care. A collaborative process, SDM actively involves the patient, the health care provider, and an extended network in making treatment decisions. Adherence to disease-modifying drug therapies in patients with MS presents an ongoing challenge for patients and health care providers due to the chronic nature of this disease. This narrative review aims to explore the impact of SDM on adherence based on existing literature and to identify new approaches to optimizing adherence. METHODS A search was conducted using medical subject heading terms, including decision-making, adherence, shared decision-making, compliance, and patient-centered care. RESULTS Shared decision making between patients and clinicians promotes adherence to the treatment plan in MS. A proactive SDM approach is based on patient preferences, education, and engagement. Providing credible and accurate sources of information is essential for improving patient engagement. Home monitoring, computerized models, and active patient engagement are a few new approaches to improve adherence in patients with MS. CONCLUSIONS Shared decision-making interventions can have a positive effect on patient adherence to disease-modifying drug therapy in MS care. A range of new strategies is emerging that may help promote optimal disease management.

Abstract
OBJECTIVE The introduction of oral disease-modifying drugs (DMDs) in addition to the available, injectable, ones for relapsing-remitting multiple sclerosis (RRMS) could be expected to improve medication persistence due to a greater acceptability of the route of administration. The aim of the study was to compare the proportion of patients discontinuing injectable DMDs (interferon beta 1a/1b, pegylated interferon, glatiramer acetate) with those discontinuing oral DMDs (dimethylfumarate and teriflunomide) during an observation period of at least 12 months. Secondary aims were to compare the time to discontinuation and the reasons for discontinuation between the two groups and to explore the demographic and clinical factors associated with DMD discontinuation. METHODS In this prospective, multi-center, real-life observational study, patients commencing any first-line DMD between 1 January 2015 and 31 July 2016 were enrolled and followed up for at least 12 months or until the drug was discontinued. RESULTS Of the 520 included patients, 262 (49.6%) started an injectable and 258 (50.4%) an oral DMD. There was no difference in the proportion of patients on oral (n = 62, 24%) or on injectable (n = 60, 23%) DMDs discontinuing treatment, the most frequent reason being adverse events/side-effects. Higher baseline Expanded Disability Status Scale (EDSS) scores and younger age increased the odds of treatment withdrawal. Time to treatment discontinuation was not different between the two groups and was not influenced by the initiated DMD (oral versus injectable), even after adjustment for baseline differences. CONCLUSION The route of administration alone (i.e. oral versus injectable) was not a significant predictor of persistence with first-line DMDs in RRMS.

Abstract
PURPOSE Treatment adherence is a prerequisite for treatment success and therefore an important consideration to assure that therapeutic goals are achieved both from a patient point of view and for optimal health care resource utilization. Published data on treatment adherence with fingolimod (Gilenya®) are limited. Therefore, this study investigated treatment adherence in patients with relapsing-remitting multiple sclerosis (RRMS) treated with fingolimod in Denmark. PATIENTS AND METHODS This was a 24-month, multicenter, open-label study, investigating treatment adherence, satisfaction, motivation, and health-related quality of life (QoL) in RRMS patients treated with fingolimod. In addition, the effect of a motivational interview support program on these measures was evaluated. Treatment adherence was assessed by pill count. Treatment satisfaction, motivation, and QoL were assessed by patient-reported outcomes (PROs). RESULTS A total of 195 patients were enrolled in the study. A very high treatment adherence was observed during the entire study with no statistically significant difference between study visits before (99%) and after (97%) the motivational interview. In accordance, a high level of treatment satisfaction was found in the Treatment Satisfaction Questionnaire for Medication 9, which was scored high throughout the study with the highest scores seen for the convenience domain (ranging from 94.51 to 95.78). Furthermore, additional PROs demonstrated a high health-related QoL, a self-determined form of motivation for taking medication, and a patient perception of an autonomy supportive approach provided by the health care provider, at all study visits. CONCLUSION High levels of treatment adherence, satisfaction, motivation, and QoL were observed in Danish RRMS patients treated with fingolimod. As these positive measures were observed at all study visits and throughout the study, no effect of the motivational interview support program was found.

Abstract
Multiple sclerosis treatment faces tremendous changes as a result of the approval of new medications. The new medications have differing safety considerations and risks after long-term treatment, which are important for treating physicians to optimize and individualize multiple sclerosis care. Since the approval of the first multiple sclerosis capsule, fingolimod, the armamentarium of multiple sclerosis therapy has grown with the orally available medications dimethyl fumarate and teriflunomide. Fingolimod is mainly associated with cardiac side effects, dimethyl fumarate with bowel symptoms. Several reports about progressive multifocal leukoencephalopathy as a result of dimethyl fumarate or fingolimod therapy raised the awareness of fatal opportunistic infections. Alemtuzumab, a CD52-depleting antibody, is highly effective in reducing relapses but leads to secondary immunity with mainly thyroid disorders in about 30% of patients. Development of secondary B-cell-mediated disease might also be a risk of this antibody. The follow-up drug of the B-cell-depleting antibody rituximab, ocrelizumab, is mainly associated with infusion-related reactions; long-term data are scarce. The medication daclizumab high yield process, acting via the activation of CD56bright natural killer cells, can induce the elevation of liver function enzymes, but also fulminant liver failure has been reported. Therefore, daclizumab has been retracted from the market. Long-term data on the purine nucleoside cladribine in MS therapy, recently authorized in the European Union, have been acquired during the long-term follow-up of the cladribine studies. The small molecule laquinimod is currently under development. We review data of clinical trials and their extensions regarding long-term efficacy and side effects, which might be associated with long-term treatment.

Abstract
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.

Abstract
OBJECTIVES Adherence to multiple sclerosis (MS) treatment is essential to optimize the likelihood of full treatment effect. This prospective, observational, single-center cohort study investigated adherence to fingolimod over the 2 years following treatment initiation. Two facets of adherence - implementation and persistence - were examined and compared between new and experienced users of disease-modifying treatments (DMTs). MATERIALS AND METHODS Implementation rates were based on the proportion of days covered and calculated as percentages per half-yearly visits and over 2 years, captured through refill data, pill count, and self-report. Nonadherence was defined as taking less than 85.8% of prescribed pills. Implementation rates were classified as nonadherent (<85.8%), suboptimally adherent (≥85.8% but <96.2%), and optimally adherent (≥96.2%), including perfectly adherent (100%). Persistence, ie, time until discontinuation, was analyzed by Kaplan-Meier analysis. Reasons for discontinuation were recorded. RESULTS The cohort included 98 patients with relapsing MS, all of whom received a dedicated education session about their medication. Of these 80% were women, 31.6% had fingolimod as first DMT, and 68.4% had switched from other DMTs. The mean implementation rate over 2 years was 98.6% (IQR1-3 98.51%-98.7%) and did not change significantly over time; 89% of measurements were in the optimally adherent category, 45.6% in the perfectly adherent category. There was one single occurrence of nonadherence. New users of DMTs were 1.29 times more likely to be adherent than experienced users (OR 1.29, 95% CI 1.11-1.51; P<0.001), but not more persistent. Nineteen of 98 patients discontinued fingolimod. CONCLUSION The very high implementation rates displayed in this sample of MS patients suggest that facilitation by health care professionals in preserving adherence behavior may be sufficient for the majority of patients. Targeted interventions should focus on patients who are nonadherent or who stop treatment without intention to reinitiate.
