A Study to Investigate Efficacy and Safety of AZD1163 in Participants With Rheumatoid Arthritis

Summary

Phase II study in participants with moderately-to-severely active rheumatoid Arthritis (RA) to evaluate efficacy and safety of AZD1163.

Detailed Description

AZD1163 is a novel bispecific antibody that inhibits the activity of extracellular peptidyl arginine deiminase 2 (PAD2) and peptidyl arginine deiminase 4 (PAD4) enzymes, which are responsible for protein citrullination. In RA, citrullinated proteins lead to the production of pathogenic anti-citrullinated peptide antibodies (ACPA). This is a Phase II, randomised, double-blind, multicentre, 4 arm placebo-controlled study designed to evaluate the efficacy and safety of AZD1163 in ACPA + adults with moderate-to-severely active RA on standard of care (SoC) (conventional synthetic disease-modifying antirheumatic drugs \[csDMARDs\] or tumour necrosis factor inhibitor \[TNFi\] +/- csDMARD). The study will have a screening period followed by a randomisation period wherein approximately 320 participants will be randomised in a 1:1:1:1 ratio to receive study intervention. Participants will receive subcutaneous (SC) injection of one of three different doses of AZD1163 or placebo, along with SoC until Week 24 followed by a safety follow-up (FU) period of 28 weeks.
