A Trial of TH-302 in Combination With Doxorubicin Versus Doxorubicin Alone to Treat Patients With Locally Advanced Unresectable or Metastatic Soft Tissue Sarcoma
- Conditions
- Soft Tissue Sarcoma
- Interventions
- Registration Number
- NCT01440088
- Lead Sponsor
- Threshold Pharmaceuticals
- Brief Summary
The purpose of this study is to determine whether TH-302 in combination with Doxorubicin is safe and effective in the treatment of Locally Advanced Unresectable or Metastatic Soft Tissue Sarcoma.
- Detailed Description
TH-302 is designed to target the hypoxic regions of tumors which are generally located distant from tumor vessels. Doxorubicin has poor tissue penetration and targets the regions of tumors that are located in proximity to the tumor vessels. The presence of hypoxia in solid tumors is associated with a more malignant phenotype and resistance to chemotherapy. The hypoxia-activated prodrug, TH-302, is designed to selectively target the hypoxic microenvironment. Soft tissue sarcomas have evidence supporting the presence of hypoxia based on pO2 histography, F-MISO and gene expression profiling. There is an absence of therapeutic options for subjects with soft tissue sarcoma. Combining doxorubicin with TH-302 may enable the targeting of both the normoxic and hypoxic regions of soft tissue sarcoma.

- Females who are pregnant or breast-feeding
- Concomitant disease or condition that could interfere with the conduct of the study, or that would, in the opinion of the investigator, pose an unacceptable risk to the subject in this study
- Unwillingness or inability to comply with the study protocol for any reason
