Conditions: Adult Solid Tumor
Keywords: TRC105 CD105 Endoglin Solid Tumors Avastin Bevacizumab
Allocation: NA | Intervention model: SINGLE_GROUP
Enrollment: 38
Healthy volunteers: no

Brief summary:
The purpose of the study is to evaluate safety and tolerability and determine a recommended Phase 2 dose for TRC105 when added to standard dose bevacizumab in patients with advanced solid tumors for which bevacizumab is indicated.

Detailed description:
Bevacizumab is a monoclonal antibody to vascular endothelial growth factor (VEGF) that inhibits angiogenesis and extends survival in patients with a wide variety of solid tumor types. TRC105, a monoclonal antibody to CD105, is a novel angiogenesis inhibitor that complements bevacizumab in preclinical models. Together, these antibodies may result in more effective angiogenesis inhibition and improved clinical efficacy over that seen with bevacizumab alone. The purpose of the study is to evaluate safety and tolerability and determine a recommended Phase 2 dose for TRC105 when added to standard dose bevacizumab in patients with advanced solid tumors for which bevacizumab is indicated.

Arms:
arm 1: Escalating doses of i.v. TRC105 will be administered weekly beginning with 3 mg/kg in combination with 15 mg/kg bevacizumab given every 3 weeks. Patients will receive TRC105 treatment on Days 1, 8, and 15 and bevacizumab treatment on Day 1 of each 21-day cycle.
