A Phase 1b Study of Imvotamab in Moderate to Severe Rheumatoid Arthritis

This is a Phase 1b, randomized, placebo-controlled, multicenter study to determine the safety, tolerability, pharmacokinetics (PK), and pharmacodynamics (PD) of imvotamab in adult participants with active RA who are refractory or intolerant to 2 previous biologic disease-modifying anti-rheumatic drugs (bDMARD) or targeted synthetic disease-modifying anti-rheumatic drugs (tsDMARD) therapies. Approximately 40 participants will be sequentially assigned to different dose escalation cohorts.
