Study start date: December 5, 2025

Actual date on which the first participant was enrolled.

This study focuses on evaluating how effective and safe a drug called Afimkibart (RO7790121) is for people suffering from moderate to severe rheumatoid arthritis. These individuals have not had satisfactory results or cannot tolerate treatment with TNF and/or JAK inhibitors, which are common medications for managing this condition. The study is important because it aims to find an alternative treatment option for those who have limited or no benefit from existing therapies, potentially improving their quality of life. Participants in the study will receive either Afimkibart or a placebo, which is a substance with no active medication, to compare the effects. The treatment will be administered under controlled conditions, and researchers will closely monitor participants to determine how well the drug works in reducing symptoms of rheumatoid arthritis and to check for any side effects. Although no specific primary outcomes are listed, the study's main focus is on assessing both the effectiveness and safety of Afimkibart.
