Disparities in DMT treatment: Demographic and neurocognitive differences between MS patients currently treated versus not treated with disease-modifying therapies. Mult Scler Relat Disord 2024; 85:105508. [PMID: 38452646 DOI: 10.1016/j.msard.2024.105508] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Revised: 01/26/2024] [Accepted: 02/17/2024] [Indexed: 03/09/2024]
Abstract
BACKGROUND Current treatment guidelines recommend consideration of disease-modifying therapy (DMT) for all multiple sclerosis (MS) patients, but barriers to access have begun to be identified. In particular, prior studies have found that people with higher education have better access to DMTs, perhaps explained by the association of higher education with higher income. And while the majority of people with MS are women, being male is also associated with higher income. These factors argue for the need to better understand whether there are differences in DMT uptake based on sex and education. Finally, in addition to well-documented benefits of DMTs for slowing disease progression, there is growing evidence to suggest benefits of DMTs for cognitive functioning. OBJECTIVE Determine whether rates of DMT treatment differ based on education and sex. Secondarily, we investigate whether neurocognitive test performance differs in treated versus not treated groups. METHODS In cross-sectional data, mixed effects linear regression evaluated differences in education and sex of those treated versus not treated with DMTs. Models included the following predictors: age, disease duration, MS subtype, sex/education, disability, atrophy, and T2 lesion volume. Propensity score weights were extracted to obtain unbiased estimates of the relationship between DMT status and each outcome of interest. The same models evaluated performance differences between groups on an iPad-based processing speed test (PST) and manual dexterity test (MDT). RESULTS Controlling for covariates, individuals with less education (OR=1.09, 95 % CI=[1.03, 1.14], p = 0.003) and women (OR=0.80, 95 % CI=[0.72, 0.90], p < 0.001) were less likely to be currently treated with DMTs. Small effect size association was shown for DMT treatment with better performance on PST (beta=0.09, CI=[0.06, 0.13], p < 0.001) and MDT (beta=0.05, CI=[0.01,0.08], p = 0.011). CONCLUSIONS Women and people with lower education had a lower likelihood of being currently treated with DMTs. After controlling for all relevant variables, an independent (small) association of DMT treatment to better performance on tests of processing speed and fine motor dexterity was found. Reasons for disparities remain to be investigated in future work, and may include employment status, health insurance coverage, or sex differences in risk tolerance.

Abstract
BACKGROUND Limited evidence exists regarding care pathways for stroke survivors who do and do not receive poststroke spasticity (PSS) treatment. METHODS Administrative data was used to identify adults who experienced a stroke and sought acute care between 2012 and 2017 in Alberta, Canada. Pathways of stroke care within the health care system were determined among those who initiated PSS treatment (PSS treatment group: outpatient pharmacy dispensation of an anti-spastic medication, focal chemo-denervation injection, or a spasticity tertiary clinic visit) and those who did not (non-PSS treatment group). Time from the stroke event until spasticity treatment initiation, and setting where treatment was initiated were reported. Descriptive statistics were performed. RESULTS Health care settings within the pathways of stroke care that the PSS (n = 1,079) and non-PSS (n = 22,922) treatment groups encountered were the emergency department (86 and 84%), acute inpatient care (80 and 69%), inpatient rehabilitation (40 and 12%), and long-term care (19 and 13%), respectively. PSS treatment was initiated a median of 291 (interquartile range 625) days after the stroke event, and most often in the community when patients were residing at home (45%), followed by "other" settings (22%), inpatient rehabilitation (18%), long-term care (11%), and acute inpatient care (4%). CONCLUSIONS To our knowledge, this is the first population based cohort study describing pathways of care among adults with stroke who subsequently did or did not initiate spasticity treatment. Areas for improvement in care may include strategies for earlier identification and treatment of PSS.

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 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.

Impact of adherence to disease modifying therapies on long-term clinical and economic outcomes in multiple sclerosis: A claims analysis of real-world data. Mult Scler Relat Disord 2023; 77:104866.

Abstract
BACKGROUND Multiple sclerosis (MS) is a chronic neurodegenerative inflammatory disease that requires long-term commitment to treatment for optimal outcomes. A variety of disease-modifying therapies (DMTs) are now available that reduce relapses and delay disease progression in people with MS. However, adherence remains a significant issue, with a variety of mental, physical, and emotional factors contributing to non-adherence. In a large number of studies, non-adherence has been associated with worse clinical outcomes (relapses and disease severity), a higher economic burden, and loss of work productivity. However, many of these studies were short-term (1-2 years) or cross-sectional studies; thus, more data are needed on the long-term clinical and economic impacts of DMT non-adherence. The objective of this study was to determine the longer-term impact of adherence to DMTs on disease activity and healthcare resource utilization (HCRU) in people with MS. The study hypothesis was that non-adherence to DMTs would be associated long-term with worse clinical outcomes and a higher economic burden. METHODS A retrospective administrative claims analysis of the US MarketScan® Commercial database (2011-2017) in individuals (18-65 years) with MS (based on International Classification of Disease coding) was conducted. Adherence was classified by proportion of days covered (PDC) ≥0.8 and non-adherence by PDC <0.8; sensitivity analyses helped further categorize as moderately (PDC ≥0.6-<0.8) or highly (PDC <0.6) non-adherent. Cohorts were matched using propensity score matching. Time to first relapse, annualized relapse rate (ARR), time to use of assistive devices (cane/walker or wheelchair), and annual HCRU (inpatient, emergency room [ER], outpatient, and MRI visits and costs) were compared between cohorts. RESULTS 10,248 MS cases were identified; 58% met adherence criteria, and 42% met non-adherence criteria. Mean follow-up from diagnosis or first DMT claim was 5.3 years. Adherent individuals had a longer time to first relapse (hazard ratio [HR] 0.83; 95% confidence interval [CI]: 0.77-0.90; p<0.0001), a lower ARR (0.13 vs. 0.18, respectively; rate ratio [RR] 0.75 [95% CI: 0.71-0.79]; p<0.0001), and longer lag times to cane/walker use (HR 0.79 [95% CI: 0.66-0.94]; p=0.0067) and wheelchair use (HR 0.68 [95% CI: 0.55-0.83]; p=0.0002) than non-adherent individuals. Adherent individuals had fewer annual inpatient and ER visits and lower total costs than those who were non-adherent (p<0.0001). Sensitivity analyses showed that differences in disease activity and HCRU were generally more pronounced between matched adherent and highly non-adherent pairs than between matched adherent and moderately non-adherent pairs. CONCLUSION Significant differences in MS disease activity and HCRU were observed based on adherence to DMTs. Our study underscores the negative impact of non-adherence to DMTs on long-term clinical and economic outcomes in MS.

Abstract
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.

Abstract
INTRODUCTION Adherence to disease-modifying therapies is key for achieving optimal outcomes in multiple sclerosis (MS). Diroximel fumarate (DRF) is an oral fumarate approved for treatment of relapsing forms of MS. It has the same pharmacologically active metabolite as dimethyl fumarate (DMF) and similar efficacy and safety profiles, but with demonstrated fewer gastrointestinal (GI) related adverse events (AEs). There are limited data characterizing persistence and adherence to DRF in the real world. METHODS This retrospective analysis of the AcariaHealth Specialty Pharmacy Program included patients with MS initiating DRF from 1 December 2019 to 30 January 2021. This analysis evaluated persistence, measured as proportion of patients remaining on therapy; discontinuation rate due to GI AEs; and adherence measured by proportion of days covered (PDC). RESULTS Overall, 1143 patients were included; 433 (37.9%) patients had been treated with prior DMF and switched to DRF. Persistence was high in both groups: the estimated proportion of patients remaining on DRF at 16 months was 82.3% [95% confidence internal (CI) 77.2-86.3%], and 90.1% (95% CI 82.2-94.6%) in the DMF to DRF group. Fifty-two (4.5%) patients overall and 15 (3.5%) in the DMF switch subgroup discontinued DRF due to GI AEs. Mean PDC was 90.8% (95% CI 89.2-92.5%), and 85.4% (95% CI 83.3-87.4%) of patients achieved PDC ≥ 80% in the overall population. In the DMF to DRF group, mean PDC was 90.7% (95% CI 88.0-93.5%), and 84.8% (95% CI 81.4-88.1%) of patients achieved PDC ≥ 80%. CONCLUSION In this analysis of > 1000 patients treated with DRF in real-world clinical practice, overall persistence at 16 months was high, treatment discontinuation due to GI AEs was low, and patients were highly adherent to therapy. Of 433 patients who switched from DMF to DRF, most (> 90%) were able to tolerate and persist on DRF after switching. Graphical abstract available for this article.

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.

Abstract
Background Adherence to disease-modifying therapy is important in patients with Multiple Sclerosis (MS) to increase the positive outcomes and improve the quality of life. This study aimed to determine the effects of Continuous Care Model (CCM) using a smartphone application on adherence to treatment and self-efficacy among MS patients. Methods This quasi-experimental study with pre/posttest design was conducted on 72 MS patients in Shiraz, Iran from June 2020 to August 2021. The samples were randomly assigned to intervention (n = 36) and control (n = 36) groups. In the intervention group, the CCM using a smartphone application was implemented during two months. However, no intervention was performed for the control group. The data were collected using the self-report Multiple Sclerosis Treatment Adherence Questionnaire (MS-TAQ) and MS Self-Efficacy Scale (MSSS) at baseline and two and four months after the intervention. Results The results showed an improvement in adherence to treatment and self-efficacy in the intervention group compared to the control group after implementing the virtual CCM and at the two-month follow-up (p < 0.001). Conclusions Implementing the CCM using a smartphone application resulted in improvements in the MS patients’ adherence to treatment and self-efficacy. It can be concluded that providing care using an interactive multimedia application can improve the outcomes as well as patients’ satisfaction, especially during the COVID-19 pandemic. Therefore, this approach is recommended to be used for nurses, healthcare providers, and clinicians.

Abstract
Background: An early treatment start with disease modifying therapies (DMT) and long-term adherence is crucial in the treatment of people with multiple sclerosis (PwMS) to prevent future disability. Objectives: To gain information on the diagnostic process, decision making, treatment start and adherence with regard to DMT as well as satisfaction in PwMS in Switzerland to optimize management of PwMS. Methods: A survey was conducted between June 2017 and March 2018 in six hospital-based MS centres and eight private practices in Switzerland. PwMS according to the 2010 McDonald criteria, aged 18–60 years, having a clinical isolated syndrome, relapsing remitting MS, or secondary progressive MS were eligible. The survey contained 40 questions, covering participants’ background and circumstances, treatment decisions, therapy start, treatment adherence, and satisfaction (EKNZ Req-2016-00701). Results: 212 questionnaires were returned for analysis. Of these, 125 (59.0%) were answered by patients treated by practice-based neurologists and 85 (40.1%) by patients treated in hospitals. That PwMS were satisfied overall with current medical care, that they were free of relapses and disease progression, and that they were able to live independently were the main goals of patients. Satisfaction was reflected by an early therapy start and a high adherence to DMT in our cohort. The treating neurologist played a major role in this regard. Furthermore, a satisfactory first diagnostic consultation (FDC) was crucial for successful long-term patient care positively influencing an early treatment start, longer duration of the initial therapy, as well as adherence to treatments and general satisfaction. Conclusion: The treating neurologist and especially a satisfactory FDC play a major role for the successful long-term treatment of PwMS. Detailed information on various aspects of the disease and time with the treating neurologist seems to be of major importance.

Clinical and real-world studies of DRF have demonstrated improved gastrointestinal (GI) tolerability and low (< 1%) GI-related treatment discontinuation versus dimethyl fumarate (DMF) and high rates of treatment adherence. Our aim was to conduct a concept elicitation study to identify treatment-related concepts most meaningful to patients and to evaluate how these concepts shape the patient perspective of DRF. METHODS In-depth qualitative interviews were conducted with patients from October to December 2020. US adults who had been prescribed DRF through routine clinical care and had taken DRF for ≥ 3 weeks in the past 6 months were eligible to participate. Semi-structured interviews explored patient perceptions on treatment selection and impact. RESULTS Seventeen patients participated in the study. Mean (SD) age was 49.3 (12.0) years. Sixteen patients reported prior disease-modifying therapy, while 10 (58.8%) had prior DMF. DRF treatment duration ranged from ~ 6 weeks to 10 months. Four key concepts emerged: (1) overall wellness and quality of life, (2) ease of administration, (3) minimal and manageable side effects, and (4) patient optimism due to MS treatments. Mode of administration (82.4%), no/mild side effects (70.6%), convenience over injectable/infusion medications (58.8%), and effectiveness (64.7%) were cited as positive aspects of DRF treatment. Frequent dosing (52.9%) and food requirements (41.2%) were cited as negative attributes; however, 94.1% had no dietary changes since starting treatment. CONCLUSION The patient perspective is a key aspect when considering a disease-modifying therapy for MS, given the multitude of options currently available. Overall wellness, ease of administration, and minimal and manageable side effects were DRF-related concepts most meaningful to patients on therapy. Acknowledging these patient perceptions in shared decision-making may lead to greater patient adherence and optimal treatment outcomes.

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
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.

Abstract
BACKGROUND Optimal self-management seem to be protective factor of health-related quality of life and psychological well-being in many chronic conditions. However, the results in people with multiple sclerosis (MS) are still inconclusive. Thus, the aim of this study is to assess the associations between self-management, self-esteem and psychological well-being in people with MS when controlled for sociodemographic and clinical variables. METHODS A total of 165 people with MS filled in The Multiple Sclerosis Self-Management Scale, Rosenberg Self-Esteem scale, and General Health Questionnaire-28, to assess main variables under study. Functional status was measured by Kurtzke disability Status Scale. RESULTS We found significant associations between self-esteem and somatic symptoms, anxiety/insomnia, social dysfunction and severe depression. Explained variance of the models ranged from 16% to 38% for somatic symptoms and severe depression, respectively. Self-management significantly contributed to the explained variance in all models sans GHQ social dysfunction. Self-esteem was significant contributor to overall variance in all models. DISCUSSION According to our results, self-management and self-esteem were found to be associated with multiple domains of psychological well-being. These findings may be used in neurological practice, to help people with MS who report psychological distress in one or more domains.

Abstract
BACKGROUND Multiple sclerosis (MS) is a chronic disabling, demyelinating disease of the central nervous system and is often associated with psychiatric comorbidities. Some studies suggest increased prevalence of bipolar disorder (BD) in MS. OBJECTIVE To conduct a systematic review and meta-analysis assessing the prevalence of BD in adults with MS. METHODS We registered this review with PROSPERO and searched electronic databases (Ovid MEDLINE, Central, Embase, PsycINFO and Scopus) for eligible studies from earliest inception to October 2020. Prevalence data of BD in adult patients with MS were extracted. Meta-analysis was conducted using random-effects model. FINDINGS Of the 802 articles that were screened, 23 studies enrolling a total of 68 796 patients were included in the systematic review and meta-analysis. The pooled prevalence rate of BD in patients with MS was 2.95% (95% CI 2.12% to 4.09%) with higher prevalence in the Americas versus Europe. The lifetime prevalence of BD was 8.4% in patients with MS. Subgroup analysis showed a higher prevalence of BD in MS in females (7.03%) than in males (5.64%), which did not reach statistical significance (p=0.53). CONCLUSIONS This meta-analysis suggests a high lifetime prevalence of BD in patients with MS. Patients with MS should be routinely screened for BD. Further assessment of bipolar comorbidity in MS through prospective studies may help in developing effective management strategies and may improve treatment outcomes in patients with MS.

Neurol Ther 2021; 10:349-360. [PMID: 33846959 PMCID: PMC8140165 DOI: 10.1007/s40120-021-00242-7] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/01/2021] [Accepted: 03/10/2021] [Indexed: 12/13/2022] Open
Abstract
Introduction Persistence to multiple sclerosis (MS) disease-modifying therapy is fundamental for maximal treatment outcomes. Diroximel fumarate (DRF) is approved in the USA for relapsing MS. Following oral administration, DRF is metabolized to monomethyl fumarate, the active metabolite of dimethyl fumarate (DMF). DRF showed clinically significant improvements in gastrointestinal (GI) tolerability versus DMF in a head-to-head clinical trial; however, real-world persistence/adherence has not been assessed. We evaluated persistence/adherence in DRF-treated patients in a real-world clinical practice. Methods This retrospective analysis of the AcariaHealth Specialty Pharmacy Program included patients initiating DRF from 4 December 2019 through 3 April 2020 and followed until data extraction (31 August 2020). Exclusion criteria included undetermined treatment status (e.g., DRF prescription transfer to a different pharmacy). Endpoints included persistence (overall proportion of patients remaining on DRF), discontinuation rate due to GI adverse events (AEs), and adherence (proportion of days covered [PDC]). GI AEs included GI-related AEs occurring at any time, or any unknown AE without details about the nature of the event if the unknown AE occurred ≤ 90 days after DRF initiation. Results Overall, 160 patients with MS were included. Median (range) patient age was 51 (20−79) years, 80.6% (129/160) of patients were female, and 16.3% (26/160) had prior DMF treatment. Median (range) treatment duration was 7.6 (0.1−10.4) months. Estimated proportion of patients remaining persistent on DRF treatment at 8 months was 88.6% (95% confidence interval [CI] 82.5–2.7). Overall, 3.8% (6/160) of patients discontinued due to GI AEs. Mean PDC was 91.4% (95% CI 89.1−93.7). In a DMF-to-DRF switch subgroup, 92.3% (24/26) remained persistent on DRF, and 3.8% (1/26) discontinued DRF due to GI AEs. Conclusion This real-world analysis of DRF-treated patients showed high overall persistence, low discontinuation rate due to GI AEs, and high adherence to therapy, aligning with expectations based on DRF clinical trials. Data were consistent in the DMF-to-DRF subgroup. Infographic ![]()

Abstract
“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.

Abstract
BACKGROUND Peginterferon beta-1a administered every 2 weeks via subcutaneous (SC) injection is approved to treat adult patients with relapsing-remitting multiple sclerosis (RRMS) and relapsing forms of multiple sclerosis (RMS). However, associated injection site reactions (ISRs) can lead to treatment discontinuation. Prior studies with interferon beta-1a reported a lower frequency of ISRs with intramuscular (IM) administration than with SC administration. IM administration of peginterferon beta-1a may therefore represent a useful alternative treatment option. METHODS A phase I, open-label, two-period crossover study randomized healthy volunteers to receive a single dose of peginterferon beta-1a 125 mcg administered IM followed by a single 125 mcg dose administered SC after a 28-day washout or vice versa. Blood samples were collected up to 504 h post dose to determine pharmacokinetic (PK) and pharmacodynamic (PD) profiles. The primary endpoint was assessment of bioequivalence based on maximum serum concentration (Cmax) and area under the curve from time zero extrapolated to infinity (AUCinf). Other PK parameters, as well as PD (serum neopterin) and safety profiles, were also evaluated. RESULTS The study enrolled 136 participants. Bioequivalence of IM and SC peginterferon beta-1a was established for both Cmax ([least squares (LS)] mean IM/SC ratio: 1.083 [90% confidence interval (CI), 0.975-1.203]) and AUCinf (LS mean IM/SC ratio: 1.089 [90% CI, 1.020-1.162]). Other PK and PD parameters were similar between administration routes, although moderate to high inter-subject variability was observed for IM and SC. Safety profiles were generally balanced between IM and SC administration. ISRs occurred at a lower frequency with IM [14.4% (95% CI, 8.89-21.56%)] than with SC [32.1% (95% CI, 24.29-40.70%)] administration (p = 0.0005). CONCLUSIONS These results demonstrate bioequivalence between peginterferon beta-1a IM and SC and support the consideration of IM injection of peginterferon beta-1a as a viable treatment option in patients with RRMS and RMS.

Abstract
Supplemental digital content is available in the text. BACKGROUND: Gastrointestinal (GI) adverse events (AEs) are commonly encountered with delayed-release dimethyl fumarate (DMF), an approved treatment for relapsing multiple sclerosis (MS). METHODS: Two hundred thirty-nine MS nurses from 7 countries were asked to complete a 2-round Delphi survey developed by a 7-member steering committee. Questions pertained to approaches for mitigating DMF-associated GI AEs. RESULTS: Ninety-six percent of nurses followed the label recommendation for DMF dose titration in round 1, but 77% titrated the DMF dose more slowly than recommended in round 2. Although 86% of nurses advised persons with relapsing forms of MS (PWMS) to take DMF with food, patients were not routinely informed of appropriate types of food to take with DMF. Most nurses recommended both pharmacologic and nonpharmacologic symptomatic therapies for PWMS who experienced GI AEs on DMF. Pharmacologic and nonpharmacologic symptomatic therapies were regarded as equally effective at keeping PWMS on DMF. In round 2, 58% of nurses stated that less than 10% of PWMS who temporarily discontinued DMF went on to permanently discontinue treatment. Sixty-six percent of nurses stated that less than 10% of PWMS permanently discontinued DMF because of GI AEs in the first 6 months of treatment in round 1. Most nurses agreed that patient education on potential DMF-associated GI AEs contributes to adherence. CONCLUSION: This first real-world nurse-focused assessment of approaches to caring for PWMS with DMF-associated GI AEs suggests that, with implementation of slow dose titration, symptomatic therapies, and educational consultations, most PWMS can remain on DMF and, when necessary after temporary discontinuation, successfully restart DMF.

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 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.

Abstract
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.

Abstract
BACKGROUND Considering the multiple treatments approved for multiple sclerosis (MS) by the Food and Drug Administration (FDA) and European Medicines Agency (EMA), determining a treatment strategy for patients with clinically isolated syndrome (CIS) and relapsing-remitting MS (RRMS) can be challenging. To date, an overview of the needs and preferences of patients at each treatment decision-making moment is lacking. Therefore, the aim of this systematic review is to examine the existing literature about the needs and preferences of patients with CIS and RRMS when making treatment decisions. METHODS A systematic search was done using Embase, Medline, PsychINFO, Web of Science and Google Scholar. Eligibility criteria included whether the article described a study of adults with CIS/RRMS and reported patient needs or preferences regarding first-line disease modifying treatment (DMT) decisions. Publications were categorized by treatment decision: initiation of first DMT (D1), DMT adherence/discontinuation (D2a/D2b), and switch to a second DMT (D3). A separate category was created for stated preference studies such as discrete choice experiment methods to examine the relative importance of different treatment attributes. Publications were compared to identify key factors. RESULTS The search yielded 2789 articles after removal of duplicates and 434 full-text publications were reviewed for eligibility. Twenty-four articles fulfilled all criteria: n = 5 (D1), n = 12 (D2a), n = 13 (D2b), and n = 3 (D3); six articles studied more than one treatment decision. The need for social support is important during D1. The most commonly reported reasons for adherence/discontinuation/switch included forgetfulness, side-effects, and injection-related reasons. Eight articles described preference studies; the most important DMT attributes were efficacy, mode and frequency of administration, and side-effect profile. CONCLUSIONS Understanding the needs and preferences of CIS/RRMS patients regarding DMT attributes and non-treatment related attributes are important to improve treatment decision-making and reduce non-adherence. Studies are needed to understand patient preferences upon treatment initiation. Furthermore, preference studies should include attributes based on the patient perspective.

Abstract
Interferon beta (IFNβ) was the first disease-modifying therapy available to treat multiple sclerosis (MS), providing patients with a treatment that resulted in reduced relapse rates and delays in the onset of disability. Four IFNβ drugs are currently approved to treat relapsing forms of MS: subcutaneous (SC) IFNβ-1b, SC IFNβ-1a, intramuscular IFNβ-1a, and, most recently, SC peginterferon beta-1a. Peginterferon beta-1a has an extended half-life and requires less frequent administration than other available treatments (once every 2 weeks vs every other day, 3 times per week, or weekly). Large randomized controlled clinical trials have confirmed the efficacy of interferons for the treatment of relapsing MS. The most frequent adverse events in patients receiving IFNs include injection site reactions and flu-like symptoms. Patient education and mitigation strategies are key to managing these adverse events and supporting therapy adherence. With fewer injections needed, peginterferon beta-1a is associated with less frequent discomfort, which may translate to improved adherence, a major factor in treatment efficacy. Because the available interferon therapies differ in administration route and frequency of injection, switching among these therapies may be a viable option for patients who experience issues with tolerability. Although a variety of disease-modifying therapies are now available to treat relapsing MS, the efficacy and long-term safety profile of interferons make them an important first-line option for treatment.

Abstract
Introduction In addition to a wide range of disease-related burdens, patients with multiple sclerosis (MS) are challenged by long-term medication and complex disease management plans, often leading to decreased adherence. Earlier studies have indicated that patient support through intensified communication can positively impact adherence. During recent years, the use of mobile health applications has gained importance in patient communication and disease management. Objective Our objective was to describe a novel software application providing innovative features that engage patient–physician contact and to evaluate users’ acceptance. Methods A novel software application ensuring data security was developed. Various innovative modules have been implemented, enabling bidirectional communication between treating physicians and patients, supporting therapy monitoring and management, and allowing the collection of large sets of anonymous patient data. The currently conducted FASTER study will analyze the acceptance of patients and physicians using this novel application. Results PatientConcept is a free app available for download since 2016. Meanwhile, it has been successfully implemented. First preliminary results indicate high acceptance among users. The clinical benefit will have to be tested in larger patient populations. Conclusion This ID-associated application may provide a secure, feasible, and cost-optimized possibility to intensify and simplify the communication between patients and their treating physicians, thus promising an exceptional benefit to both.

Abstract
Background:
Multiple Sclerosis (MS) is one of the most common causes of neurological disability in young and middle-aged adults. Patients with MS face many challenges, both physical and emotional, and see an overall reduction in their autonomy.
There is no definitive treatment for MS, though Disease Modifying Drugs (DMDs) have proved effective in reducing the frequency and severity of relapses. Unfortunately, long-term adherence to these therapies is a significant challenge due to practical difficulties as well as a general distrust towards the drugs
.
Objective:
This study follows an original research carried out in 2008. In the first study, patients answered questions on their clinical history and expressed their judgment on the pharmacological treatment, their perceived effectiveness and factors that may undermine compliance. They have been recalled after two years to verify if the reported symptoms have changed and to assess how their knowledge of the disease and “acceptance” of the treatment have been modified.
Methods:
In spite of the relatively high number of patients participating in the first study (141 patients followed at a single neurological centre), only 16 patients have completed the questionnaire for the long-term survey. A detailed descriptive analysis has been carried out, as well as a pairwise correlation analysis.
Results and Conclusions:
The interviews carried out gave an insight into how patients’ behavior may have changed over time. Compliance rate is different in newly-diagnosed patients and long-term patients; the latter are more likely to be compliant, given their personal experience with the disease. Communications with neurologists and health personnel should aim at forming therapeutic alliances with patients and detecting their preferences for a qualitatively adequate assistance throughout their illness.
