WIKI ANALYSISTheshold Pharmaceuticals is a biopharmaceutical company based in South San Francisco, CA that seeks to discover and develop new therapeutics for cancer via targeting tumor hypoxia, a specific condition that occurs in most tumor microenvironments that causes low oxygen concentrations. Theshold's approach is to exploit the lack of oxygen in cancer cells as opposed to normal cells by developing Hypoxia-Activated Prodrugs (HAPs).
Its lead candidate, TH-302, which is activated preferentially under hypoxic conditions has demonstrated anticancer activity in several preclinical cancer models.
