SOUTH SAN FRANCISCO, Calif., April 15, 2025 (GLOBE NEWSWIRE) -- RAPT Therapeutics, Inc. (Nasdaq: RAPT), a clinical-stage, immunology-based biopharmaceutical company focused on discovering, developing and commercializing novel therapies for patients living with inflammatory and immunological diseases, today announced the appointment of Jessica Savage, M.D., M.H.S., as Vice President, Clinical Development to oversee the development of RPT904, a novel, half-life extended monoclonal antibody designed to bind free human immunoglobin E (“IgE”), a key driver of several allergic diseases. RAPT plans to pursue development of RPT904 initially in food allergy and chronic spontaneous urticaria (“CSU”).

“We are thrilled to welcome Jessica to the RAPT leadership team at this pivotal time for the company,” said Brian Wong, M.D., Ph.D., President and CEO of RAPT. “With her deep expertise as both an allergist and immunologist, and particularly her experience in food allergy, she will be instrumental in advancing RPT904 to a Phase 2b clinical trial for food allergy in the second half of 2025 and generating important data to differentiate RPT904 as an attractive therapeutic option for patients.”

Dr. Savage added, “I am excited to join RAPT and apply my experience and expertise to the development of RPT904, which I believe has promise as a best-in-class drug for patients with food allergy. Food allergy is a large and underappreciated health problem affecting millions of people. There is a clear unmet need, and I appreciate the opportunity to be part of an innovative solution. I look forward to initiating our clinical trial and planning for eventual approval in food allergy, CSU and possibly other allergic diseases.”
