Official title: An Extension Study to Evaluate the Long-term Safety and Efficacy of Afimkibart (RO7790121) in Patients With Rheumatoid Arthritis Who Participated in Previous Afimkibart Clinical Trials
Run by Hoffmann-La Roche · NCT07620392 · Data updated 2026-11-12

Is this trial a fit for you?
✓Likely a good fit
Adults with moderate to severe rheumatoid arthritis who completed the parent study, adhered to contraception requirements, and showed improvement in joint swelling scores compared to baseline.
✕Probably not a fit
Patients who withdrew from the parent study, permanently discontinued the drug in the parent study, used prohibited therapies, or developed new uncontrolled conditions may not benefit.

What this trial studies
This is a phase 2 extension trial evaluating the long-term safety and efficacy of Afimkibart (RO7790121) in adults with rheumatoid arthritis who had an inadequate response or intolerance to TNF inhibitors and/or JAK inhibitors and previously received Afimkibart. Participants must have completed the parent study, agreed to contraception requirements, and shown improvement in joint swelling scores relative to baseline. The trial will monitor ongoing safety and track efficacy over an extended follow-up period at multiple sites in the United States. Key exclusion criteria include withdrawal from the parent study, permanent discontinuation of the drug in the parent study, use of prohibited therapies during the parent study, or new uncontrolled medical conditions that could affect participation.
Why it matters
Potential benefit: If successful, the trial could confirm extended safety and potential ongoing benefit of Afimkibart for RA patients who previously benefited from the drug.
How similar studies have gone: Prior studies of Afimkibart in RA have demonstrated some improvements, and this extension aims to assess long-term safety and durability of response.
