Randomized Controlled Trial
A Phase 2 Trial of Peresolimab for Adults with Rheumatoid Arthritis.
Peresolimab is a humanized IgG1 monoclonal antibody designed to stimulate the endogenous programmed cell death protein 1 (PD-1) inhibitory pathway. Stimulation of this pathway would be a novel approach to the treatment of patients with autoimmune or autoinflammatory diseases. ⋯ Peresolimab showed efficacy in a phase 2a trial in patients with rheumatoid arthritis. These results provide evidence that stimulation of the PD-1 receptor has potential efficacy in the treatment of rheumatoid arthritis. (Funded by Eli Lilly; ClinicalTrials.gov number, NCT04634253.).
