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

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.

Enduring Clinical Value of Copaxone® (Glatiramer Acetate) in Multiple Sclerosis after 20 Years of Use

Multiple sclerosis (MS) is a chronic progressive neurodegenerative demyelinating disease affecting the central nervous system. Glatiramer acetate (GA; Copaxone®) was the first disease-modifying treatment (DMT) for MS successfully tested in humans (1977) and was approved by the US Food and Drug Administration in December 1996. Since then, there have been numerous developments in the MS field: advances in neuroimaging allowing more rapid and accurate diagnosis; the availability of a range of DMTs including immunosuppressant monoclonal antibodies and oral agents; a more holistic approach to treatment by multidisciplinary teams; and an improved awareness of the need to consider a patient's preferences and patient-reported outcomes such as quality of life. The use of GA has endured throughout these advances. The purpose of this article is to provide an overview of the important developments in the MS field during the 20 years since GA was approved and to review clinical data for GA in MS, with the aim of understanding the continued and widespread use of GA. Both drug-related (efficacy versus side-effect profile and monitoring requirements) and patient factors (preferences regarding mode of administration and possible pregnancy) will be explored.

Interventions to support risk and benefit understanding of disease-modifying drugs in Multiple Sclerosis patients: A systematic review

OBJECTIVE

The present review evaluates interventions that have been designed to improve understanding of the complex risk-benefit profiles of disease-modifying drugs (DMDs) in patients with Multiple Sclerosis (MS).

METHODS

A systematic search conducted using PubMed, Embase, Google Scholar and PsycINFO identified 15 studies. Interventions which provided treatment information were present across a range of study designs. A narrative synthesis was conducted due to heterogeneity of research findings.

RESULTS

Interventions providing treatment information ranged from comprehensive education programmes to booklets of a few pages. MS patients favoured the interventions they received. Understanding of overall treatment information and treatment risks specifically, generally improved following interventions. Yet overestimation of treatment benefits persisted. There was no conclusive effect on DMD decisions. No superior intervention was identified.

CONCLUSION

Interventions designed to improve understanding of DMD risk and benefit information are moderately successful.

PRACTICE IMPLICATIONS

Additional support provided to MS patients beyond routine healthcare can generally improve understanding of the complex risk-benefit profiles of DMDs. Future interventions need to ensure that patients with symptoms that may confound understanding can also benefit from this additional information.

Multiple Sclerosis Therapy With Disease-Modifying Treatments in Germany: The PEARL (ProspEctive phArmacoeconomic cohoRt evaluation) Noninterventional Study Protocol

Background

Patients with multiple sclerosis (MS) require long-term therapy and have a wide variety of needs for health-related support. The efficacy and safety of MS therapy, as assessed by both clinicians and patients, are important parameters that need to be considered. However, few studies combine data on efficacy and safety outcomes with pharmacoeconomic data.

Objective

Here, we present the study design of the ProspEctive phArmacoeconomic cohoRt evaluation (PEARL), a prospective, multicenter, noninterventional cohort study on patients with relapsing-remitting MS (RRMS) treated with disease-modifying treatments (DMTs).

Methods

During a prospective observational phase of 24 months per patient, PEARL evaluated clinical and patient-perceived efficacy and safety measures, as well as pharmacoeconomic data on RRMS patients treated with DMTs—interferon beta and glatiramer acetate. Measurements of the patients' perceptions included the assessment of patient-reported quality of life, treatment satisfaction, and compliance. The study was planned to include 1800 outpatients from 180 German neurological practices who had continuously been treated with an approved DMT for at least 30 days. The primary statistical analyses of the PEARL study will be descriptive. Particular focus will be on specific subgroups, such as patients who switched DMTs during therapy and patients with disease worsening or disease activity. Subgroups will be compared using stratified analyses.

Results

Data collection for PEARL started in September 2010 and ended in July 2013. As of July 2015, the study is completed and is currently being analyzed and written up.

Conclusions

PEARL is evaluating both the health status and resource utilization of RRMS patients treated with DMTs in Germany. The combination of pharmacoeconomic data with clinical and patients' self-perceived efficacy and safety outcomes will add useful information to the currently incomplete picture of the overall RRMS burden in Germany.
