Star Therapeutics, a late clinical-stage biotechnology company discovering and developing best-in-class antibodies for bleeding disorders and other diseases, today announced that Adam Rosenthal, Ph.D., CEO and Founder, will present at the 44^th Annual J.P. Morgan Healthcare Conference on Monday, January 12, 2026, at 4:30 p.m. PT in San Francisco, CA.

Dr. Rosenthal will provide an overview of the company and its lead program, VGA039, a first-in-class monoclonal antibody therapy that targets Protein S, with dual actions promoting platelet attachment and enhancing fibrin deposition to restore hemostasis. VGA039 has potential to be a universal hemostatic therapy that can treat numerous bleeding disorders, starting with von Willebrand disease (VWD), and is currently being evaluated in a pivotal Phase 3 study for the treatment of VWD. Interim data from the ongoing Phase 1/2 multidose study of VGA039 in VWD were presented at the 67^th American Society of Hematology (ASH) Annual Meeting in December 2025, demonstrating substantial bleed reductions in all patients, across all types of VWD and all types of bleeds.
