• Tr1X has received an $8 million grant from the California Institute for Regenerative Medicine to support its Phase 1/2a clinical trial of TRX103, an engineered Tr1 Treg cell therapy for preventing graft-versus-host disease in mismatched stem cell transplants.
• The company has reported positive initial persistence and safety data in the first two patient cohorts of the TRX103 trial, with additional results expected later in 2025.
• TRX103 represents a potentially transformative approach to preventing GvHD without the immunosuppression drawbacks of current treatments, potentially expanding access to curative therapies for patients without matched donors.
