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