Third Harmonic Bio is a clinical-stage biotechnology company based in San Francisco, California, focused on developing an oral inhibitor of KIT. KIT is a cell-surface receptor that regulates mast cell survival and function, and mast cells are immune cells central to inflammation at the body's interfaces with the external environment. The company's aim is to deliver broad symptomatic relief for inflammatory diseases involving mast cells, including chronic spontaneous urticaria and severe asthma. It operates as a small biotechnology firm with a focused research program rather than a broad product portfolio. In April 2025, Third Harmonic Bio announced a Plan of Liquidation and Dissolution.
