Condition(s) targeted: Multiple Sclerosis, Relapsing-Remitting

Phase: N/A

Status: Completed

Sponsored by: Merck KGaA

Official(s) and/or principal investigator(s):
Michalis Arvanitis, MD, Study Director, Affiliation: Merck A.E., Greece

Summary

The present study aims to assess the adherence to therapy with interferon beta-1a (Rebif) and at investigating potential factors that are involved in its outcome, in a representative sample of patients with relapsing remitting multiple sclerosis (RRMS), under real life conditions.

Clinical Details

Official title: A Multicentre, Non Interventional, Non Randomized, Observational Study for the Assessment of Compliance and Persistence With Rebif Therapy of Patients With Relapsing-Remitting Multiple Sclerosis as Well as for the Evaluation of Potential Factors Influencing These Parameters, in Real Life Clinical Practice

Study design: Observational Model: Cohort, Time Perspective: Prospective

Primary outcome:

Assessment of subjects' compliance with physicians' instructions on the proper use of the treatment

Assessment of subjects' compliance with physicians' instructions on the proper use of the treatment after 6 months of therapy

Assessment of subjects' persistence to therapy

Secondary outcome: Assessment of the factors and their potential correlation with the defined subjects' compliance and persistence to therapy

Detailed description: In the relapsing-remitting type of the disease the objective of the therapy is the reduction of relapse rate, duration and severity, as well as the delay of transition to the progressive form of the disease. Subjects' adherence to long-term therapy of MS plays a pivotal role in the optimization of therapeutic outcome and maximization of the derived clinical benefit for the treated subjects. Rebif current formulation has been developed by assessing and refining the physicochemical characteristics of existing formulations aiming at further improving product's tolerability profile. Studies performed for the assessment of Rebif have demonstrated a 3-fold reduction in injection site reactions as well as improved overall tolerability and safety profile. This is a multicentre, prospective, non interventional, non randomized, open label study for the assessment of the adherence to therapy with Rebif of subjects with RRMS. The participating subjects shall be already on treatment with (Rebif) prior to their enrolment into the study, according to the approved Summary of Product Characteristics (SPC) and the clinical, imaging and laboratory findings of the disease, as evaluated by their treating physician, in real life clinical practice. Data will be collected retrospectively from a sample of 150 subjects' medical files and through questions that will be posed to the subjects, and prospectively during the course of the study. The total duration of the study is estimated to be 18 months. OBJECTIVES Primary objective:

- To assess the compliance and persistence with Rebif therapy in MS subjects, after six

months of therapy, in "real life" clinical settings in Greece Secondary objective:

- To investigate the potential factors influencing compliance and persistence to Rebif

therapy.
