We are a clinical stage biopharmaceutical company discovering and developing personalized therapeutics for the treatment of solid tumors and blood cancers. We focus on the development of small molecule product candidates that target cell signaling pathways that are important to driving the progression of certain cancers. We aim to employ molecular diagnostics to identify patients with cancers who are likely to benefit from our targeted product candidates. Our lead product candidate, tipifarnib, is a farnesyl transferase inhibitor that we are evaluating as a treatment for patients with certain solid tumors, including thyroid, head and neck, urothelial, and salivary cancers, with mutations in the HRAS oncogene. Collectively, the annual incidence of these cancers containing HRAS mutations is approximately 8,000 patients per year in the United States, and, in general, patients with these cancers have poor prognoses and limited options for treatment. We are also evaluating tipifarnib as a potential treatment for patients with peripheral T-cell lymphoma, which has an annual incidence of approximately 7,000-10,000 patients in the United States.
