Third Harmonic Bio, Inc. develops pharmaceutical products for the treatment of allergic and immune diseases and disorders. The company is headquartered in San Francisco, California and currently employs 53 full-time employees. The company went IPO on 2022-09-15. The firm is focused on advancing the next wave of medicine for inflammatory diseases through the development of novel, small-molecule inhibitors of KIT, a cell surface receptor that serves as the master regulator of mast cell function and survival. The company is developing medicine for the treatment of inflammatory diseases, including dermal, respiratory, and gastrointestinal diseases. Its lead product candidate, THB335, is a titratable, oral, small molecule inhibitor. Dysfunctional mast cell activity has been implicated in the pathophysiology of a broad range of mast cell driven inflammatory disorders, including urticaria, asthma and gastrointestinal disorders, among others. THB335 maintains the nonclinical pharmacology and selectivity profile of THB001, with structural modifications that are designed to functionally block the site of reactive metabolite formation to mitigate hepatotoxicity risk.
