Dose-Escalation Study of TH-302 in Combination With Sunitinib to Treat Patients With Advanced Renal Cell Carcinoma,Gastrointestinal Stromal Tumors and Pancreatic Neuroendocrine Tumors

Status unconfirmed · Phase 1

Conditions studied: Advanced Renal Cell Carcinoma, Gastrointestinal Stromal Tumors, Pancreatic Neuroendocrine Tumors

In brief

The primary objectives are: Dose escalation: 1\. To determine the MTD and DLT(s) of TH-302 when used in combination with sunitinib. Dose expansion: 1. To make a preliminary assessment of the efficacy of TH-302 in combination with sunitinib as determined by the response rate and the progression-free survival in subjects with advanced RCC treated at the RP2D 2. To assess the safety of TH-302 in combination with sunitinib and determine a recommended Phase 2 dose of the combination. The secondary objectives are: Dose expansion: 1\. To make a preliminary assessment of the efficacy of TH-302 in combination with sunitinib as determined by stable disease or better rate, duration of response and overall survival in subjects with advanced RCC treated at the RP2D. The exploratory objective is: 1\. To explore the association of serum hypoxia biomarkers with efficacy endpoints.
