Open-label, Multi-center Phase III Extension of the Double-blind, Placebo-controlled BENEFIT Study (no. 92012/304747) to Obtain Long-term Follow-up Data of Patients With Clinically Definite Multiple Sclerosis (MS) and Patients With a First Demyelinating Event Suggestive of MS Treated With 8 MIU (250 µg) Interferon Beta-1b (Betaferon® / Betaseron®) Given Subcutaneously Every Other Day for at Least 36 Months

Abstract

This study will primarily compare the long-term effects of an early and continued treatment with Betaferon/Betaseron (patients who were treated with active medication during the double-blind BENEFIT study) to treatment initiated either after Clinically Definite Multiple Sclerosis (CDMS) has been diagnosed or after two years (those patients who were treated with placebo during the double-blind BENEFIT study).

Analyses are based on the integrated data of the initial BENEFIT study and this follow-up study.

Conditions: Multiple Sclerosis.

Primary outcome: Time to Clinically Definite Multiple Sclerosis (CDMS) Represented by Kaplan-Meier Estimates of the Cumulative Percentage of Participants With CDMS at Selected Points in Time; Time to Confirmed Expanded Disability Status Scale (EDSS) Progression Represented by Kaplan-Meier Estimates of the Cumulative Percentage of Participants With Confirmed EDSS Progression at Selected Points in Time; Functional Assessment of Multiple Sclerosis (FAMS) Trial Outcome Index (TOI) at Month 60.

Enrollment: 468 participants.

How strong is the evidence?

Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 468 participants or records.

How the five levels of evidence work. The level is assigned automatically from the abstract and can be wrong, so check the paper.
