Researchers are studying AZD1163, a new bispecific antibody, to assess its effectiveness and safety in adults with moderately-to-severely active rheumatoid arthritis (RA) who test positive for anti-citrullinated peptide antibodies (ACPA). This Phase II, randomized, double-blind, placebo-controlled trial involves participants already receiving standard treatments such as conventional synthetic disease-modifying antirheumatic drugs (csDMARDs) or tumor necrosis factor inhibitors (TNFi). Participants will be randomly assigned to one of four groups to receive subcutaneous injections of either one of three doses of AZD1163 or a placebo, alongside their standard care, for 24 weeks. Following this treatment period, there will be a 28-week safety follow-up to monitor participants. Throughout the study, researchers will evaluate changes from baseline in disease activity scores using C-reactive protein levels at 12 weeks. Participants will undergo regular assessments including joint counts and laboratory tests to monitor disease status and safety. The total involvement in the study spans over 52 weeks, including treatment and follow-up periods.
