A Phase 1/2, Double-Blind, Placebo-Controlled Study of the Pharmacokinetics, Safety and Tolerability of GSK3196165 in Combination With Methotrexate Therapy, in Japanese Subjects With Active Moderate-Severe Rheumatoid Arthritis Despite Treatment With Methotrexate (NCT03028467)

This is a randomized, double-blind, parallel group, 3 dosage level, placebo-controlled, Phase 1/2 study designed to evaluate the pharmacokinetics, safety, tolerability, and efficacy of the monoclonal antibody GSK3196165, in Japanese subjects with active moderate-severe rheumatoid arthritis (RA) despite treatment with methotrexate(MTX).
