NCT01034579

Brief Summary

This study, REbif® vs Glatiramer acetate in relapsing multiple sclerosis (MS) disease - pharmacogenetic(s) (REGARD-PGx) is a single blood sampling exploratory pharmacogenetic study of the REGARD trial. The aim of this trial is to provide additional data on the factors influencing interferon (IFN) beta response. This is a Phase 4 trial involving subjects who previously participated in the REGARD trial. To address the trial objectives, a single visit follow-up trial will be performed during which a blood sample will be collected.

Outcome Measures

Primary Outcomes (1)

  • Percentage of Responders as Defined by Single Nucleotide Polymorphism (SNP) Markers

    A responder was defined as a participant with no multiple sclerosis (MS) relapse and no Expanded Disability Status Scale (EDSS) progression during 96 weeks in 24735 (NCT00078338). All responders were categorized on the basis of following six SNP markers: SNP1, SNP2, SNP3, SNP4, SNP5, and SNP6. Two types of variables were possible for each SNP marker: two-level genotype-based or three-level allele-based association variables. For the two-level genotype-based SNP markers (SNP2, SNP4, and SNP6), the absence or presence of the genotype was analyzed as the dichotomous variable as 0 (absence of the genotype) and 1 (presence of the genotype). For the three-level allele-based association SNP markers (SNP1, SNP3, and SNP5), the analysis was based on the number of copies of the allele (0, 1 and 2). Percentage of responders segregated on the basis of SNP marker variable were reported.
