A broad range of tumors have been shown to contain significant numbers of hypoxic cells and hypoxia has been shown to be associated with a poor prognosis and an increase in resistance to chemotherapy and radiotherapy (Brizel 1997, Vaupel 2007, Shannon 2003).
It is likely that an agent that could effectively target hypoxic regions in tumors would improve efficacy when combined with standard chemotherapy or radiotherapy. TH-302 is activated at lower oxygen concentrations than other bioreductive prodrugs (Duan 2008) and tirapazamine, a hypoxic cytotoxin that has been extensively studied in both preclinical and clinical studies. This should result in an improved therapeutic ratio (tumor vs normal tissue toxicity) as compared with other bioreductive agents. Because TH-302 is expected to be minimally toxic to aerobic cancer cells, optimal efficacy would be expected when TH-302 is combined with treatments that are most effective under aerobic conditions such as radiotherapy and cytotoxic chemotherapy. Preclinical data have shown at least additive efficacy when TH-302 is combined with either docetaxel or gemcitabine. In order to minimize the risk of additive toxicity, TH-302 is not being evaluated in combination with alkylating agents.
