What this trial studies

This is an open-label, single-arm, single-center early-phase 1 trial enrolling adults with refractory moderate-to-severe active rheumatoid arthritis. Participants will receive UTAA91 injections and be monitored primarily for safety using clinical exams, laboratory tests, and adverse event reporting. The study is investigator-initiated and conducted at Union Hospital, Tongji Medical College in Wuhan, with exclusions for recent malignancy, active infections, severe cardiac disease, and pregnancy. Secondary observations will record tolerability and any preliminary signs of clinical activity.

Who should consider this trial

Good fit: Adults (≥18) with moderate-to-severe active rheumatoid arthritis unresponsive to standard treatments, adequate liver/kidney/cardiopulmonary function, no severe psychiatric disorder, and able to give informed consent.

Not a fit: Patients with recent malignancy within five years, positive viral or syphilis tests, severe cardiac or unstable systemic disease, active uncontrolled infections, CNS involvement, or who are pregnant or breastfeeding are unlikely to be eligible or benefit.

Why it matters

Potential benefit: If safe, UTAA91 could provide a new treatment option for patients with refractory moderate-to-severe RA who have exhausted standard therapies.

How similar studies have performed: UTAA91 appears to be an early-phase, novel intervention with limited prior clinical data specifically for this agent, although other injectable targeted therapies for refractory RA have shown mixed early promise.
