An Efficacy and Safety Study of JNJ-38518168 in Adult Participants With Rheumatoid Arthritis

Rheumatoid Arthritis Clinical Trial

Official title: A Phase IIa Multicenter, Randomized, Double-Blind, Placebo-Controlled, Parallel Group Study of JNJ-38518168 in Patients With Active Rheumatoid Arthritis Despite Methotrexate Therapy With Synovial Biopsy Substudy

Status Terminated

Clinical Trial Summary

The purpose of this study is to evaluate the efficacy, tolerability and safety of JNJ-38518168 compared with placebo in adult participants with active rheumatoid arthritis (long time systemic disease of the joints, marked by inflammatory changes in the synovial membranes and bones) despite methotrexate (MTX) therapy.

Clinical Trial Description

This is a multi-center (when more than 1 hospital or medical school team work on a medical research study), randomized (the study drug is assigned by chance), double-blind (neither physician nor participant knows the treatment that the participant receives), placebo-controlled (an inactive substance; a pretend treatment [with no drug in it] that is compared in a clinical trial with a drug to test if the drug has a real effect) and parallel-group (each group of participants will be treated at the same time) study. The study will consist of 3 phases; Screening phase (3 weeks), Treatment phase (12 weeks) and Follow-up phase (4 weeks). Each participant will be enrolled in the study for approximately 19 weeks. Participants with active rheumatoid arthritis despite MTX therapy will receive JNJ-38518168, 100 milligram (mg) per day or matching placebo capsules once daily for 12 weeks. Efficacy will be primarily evaluated by change from Baseline in disease activity index score C-reactive protein at Week 12. Participants' safety will be monitored throughout the study. ;
