INTRODUCTION Cutaneous adverse events (AEs) have been observed in clinical studies of daclizumab high-yield process (HYP) in relapsing-remitting multiple sclerosis (RRMS). Here, we report cutaneous AEs observed in the randomized, double-blind, active-comparator DECIDE study (ClinicalTrials.gov identifier, NCT01064401). METHODS DECIDE was a randomized,(More)
The study's primary objective was to compare the pharmacokinetics (PK) and pharmacodynamics (PD) of single subcutaneous (SC) or intramuscular (IM) 300-mg doses of natalizumab with IV 300-mg doses of natalizumab in patients with multiple sclerosis (MS). Secondary objectives included investigation of the safety, tolerability, and immunogenicity of repeated SC(More)
BACKGROUND Natalizumab, an anti-α4 integrin monoclonal antibody, has demonstrated efficacy in phase 2 and 3 studies of predominantly Caucasian patients with relapsing-remitting multiple sclerosis (RRMS). OBJECTIVE To evaluate the efficacy, safety, pharmacokinetics (PK), and pharmacodynamics (PD) of natalizumab in Japanese RRMS patients. METHODS This(More)
INTRODUCTION The efficacy of natalizumab was evaluated in Japanese patients with relapsing-remitting multiple sclerosis (RRMS) in a 24-week, phase 2 bridging study. An open-label, 2-year extension study from this trial was conducted to assess the safety and efficacy of natalizumab treatment in Japanese patients. METHODS A total of 97 patients (43(More)
