Study of Safety and Efficacy of Glufosfamide in Combination With Gemcitabine in Cancer

This study, TH-CR-301, is a Phase 1/2 study that will evaluate the efficacy and safety of glufosfamide in combination with gemcitabine in advanced solid tumors or in first line treatment of pancreatic cancer.

Study Hypothesis: Glufosfamide in combination with gemcitabine may provide benefits in survival to patients with advanced solid tumors or metastatic pancreatic cancer.
