A phase 2A, randomized, double-blind, placebo-controlled, parallel-group study of CE-224,535, an antagonist of the P2X7 receptor, in the treatment of the signs and symptoms of rheumatoid arthritis in subjects WHO are inadequately controlled on methotrexate

100 participants

Abstract

CE-224,535 is known to block a chemical that acts as a gateway to some of your immune cells. Blocking this gateway prevents the cells from pushing out 2 chemicals called IL-1 and IL-18 that are known to cause some of the inflammation seen in rheumatoid arthritis. It is hoped that taking this drug will reduce the symptoms of rheumatoid arthritis

Conditions: Arthritis, Rheumatoid.

Primary outcome: Percentage of Participants With American College of Rheumatology 20% (ACR20) Response at Week 12.

Enrollment: 100 participants.
