Summary

Tonix Pharmaceuticals (NASDAQ: TNXP), a fully-integrated commercial-stage biotechnology company, announced the publication of peer-reviewed Phase 1 data for TNX-1500, its investigational anti-CD40L monoclonal antibody, in the Journal of Clinical Immunology. The study evaluated TNX-1500 in healthy volunteers and highlighted favorable safety, tolerability, and pharmacodynamic results. Specifically, TNX-1500 was generally well tolerated with no serious adverse events, demonstrated sustained suppression of T cell-dependent antibody responses, and showed a half-life supporting monthly intravenous dosing. These promising results support the advancement of TNX-1500 toward a planned Phase 2 investigator-initiated kidney transplant rejection study in the second half of 2026, pending FDA clearance. This development marks a significant step for Tonix in its immunology pipeline, which also includes TNX-4800 for Lyme disease prophylaxis.
