Long-term Follow-Up of Patients Who Participated in Study 27025 (REFLEX) (REFLEXION)
January 25, 2017 updated by: Merck KGaA, Darmstadt, Germany
Double-blind Extension of the Study 27025 (REFLEX) to Obtain Long-term Follow-up Data in Patients With Clinically Definite MS and Patients With a First Demyelinating Event at High Risk of Converting to MS, Treated With Rebif® New Formulation (REFLEXION)
REFLEXION is a double blind extension of the study 27025 (NCT00404352) (REFLEX).
The purpose of the study is to obtain long-term follow-up data in subjects with clinically definite multiple sclerosis (MS) and subjects with a first demyelinating event at high risk of converting to MS, treated with fetal bovine serum [FBS]-free/human serum albumin [HSA]-free formulation of interferon [IFN]-beta-1a (RNF).

Detailed Description
The objective of the study is to investigate whether RNF treatment initiated after the first clinical event versus delayed treatment results in the prolongation of time to Clinically Definite Multiple Sclerosis (CDMS) conversion up to Month 36 and up to Month 60 since randomization in Study 27025 (REFLEX).
Furthermore, the study is intended to explore whether RNF treatment initiated after the first clinical event versus delayed treatment delays disability (including development of secondary progressive MS) and reduces disease activity (including the annual relapse rate [ARR]) in the long term (up to Month 36 and up to Month 60 since randomization in Study 27025 (REFLEX).
The study will also assess the long-term safety profile of RNF (up to Month 36 and up to Month 60 since randomization in Study 27025 (REFLEX).

Time Frame: Baseline (Day of Study 27025), Month 36
|
The Paced Auditory Serial Addition Test (PASAT) is a measure of cognitive function that specifically assesses auditory information processing speed and flexibility, as well as calculation ability.
Score ranges from '0-60'.
Higher scores reflect better neurological function and a positive change from baseline indicates improvement.
|
Baseline (Day of Study 27025), Month 36

|
Change From Baseline in Expanded Disability Status Scale (EDSS) Score at Month 36
Time Frame: Baseline (Day of Study 27025), Month 36
|
EDSS assesses disability in 8 functional systems.

|
Change From Baseline in Multiple Sclerosis Functional Composite (MSFC) Score at Month 36
Time Frame: Baseline (Day 1 of Study 27025), Month 36
|
The MSFC is a multidimensional clinical outcome measure which consists of three sub-tests; Timed 25-Foot Walk, 9-Hole Peg Test and Paced Auditory Serial Addition Test-3(PASAT-3).
The Timed 25-Foot Walk is a quantitative measure of lower extremity function.
The 9-Hole Peg Test is a quantitative measure of upper extremity (arm and hand) function.
The PASAT is a measure of cognitive function that specifically assesses auditory information processing speed and flexibility, as well as calculation ability.
Standardized results (Z-scores) of these sub-tests and the overall MSFC Z-score as an average of these three Z-scores was calculated.
Higher Z-scores reflect better neurological function and a positive change from baseline indicates improvement.
An increase in score indicates an improvement (range -3 to +3).

Numbers of Participants With Binding Antibodies (BAb) and Neutralizing Antibody (NAb) at Month 36
Time Frame: Month 36
|
BAbs are all antibodies which are capable of binding to the investigational drug molecule (RNF) irrespective of their binding site.
NAbs are defined as a subgroup of BAbs which bind to the active sites of the RNF and therefore neutralize its potency.
NAbs were detected using a viral cytopathic assay.
BAbs were measured by using an ELISA (Enzyme-linked immunosorbent assay).
