Overview
Phase II study in participants with moderately-to-severely active rheumatoid Arthritis (RA) to evaluate efficacy and safety of AZD1163.
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 days.
Eligibility
- Inclusion
- Diagnosed with adult-onset RA as defined by the 2010 ACR/EULAR classification criteria for at least 12 weeks prior to screening.
- Moderately-to-severely active RA as defined by: a. \>= 6 swollen joints on 66SJC and \>= 6 tender joints on 68TJC; b. CRP \> upper limit of normal.
- Have a positive ACPA at screening.
- A history of inadequate response, or loss of response, or intolerance to: a. at least one csDMARD treatment, AND/OR b. At least one and at most 2 TNFi.
- A history of at least 12 weeks treatment and \>= 4 weeks stable on a csDMARD and/or SC TNFi prior to the day of randomisation.
- Exclusion
- History or evidence of an alternate autoimmune or other condition that could confound the diagnosis of RA. Participants with RA and secondary Sjogren's disease are eligible.
- Have received or planning to receive any biologic DMARDs (except for TNFi) or targeted synthetic DMARDs.
