Brief Summary
The purpose of this study is to determine if TH-302, in combination with A) Gemcitabine, or B) Docetaxel or C) Pemetrexed methotrexate, are safe and effective in the treatment of Pancreatic Cancer, Ca...
Detailed Description
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 ...
