Primary Outcome Measures:
  • Determine Maximum Tolerated Dose of TRC105 in Combination With Bevacizumab [ Time Frame: 1.5 years ]
    Safety and dose limiting toxicity will be assessed by dose cohort.


Secondary Outcome Measures:
  • TRC105 Pharmacokinetic Concentrations [ Time Frame: 1.5 years ]
    Plasma TRC105 concentrations will be measured at specified timepoints.

  • Immune Response to TRC105 [ Time Frame: 1.5 years ]
    HAMA and HACA titers will be measured at specified time-points.

  • Objective Response According to RECIST 1.1 [ Time Frame: 1.5 years ]
    The best response according to RECIST 1.1 for each patient with measurable disease and who received at least one dose of study drug will be listed by cohort and tumor type


Enrollment: 38
Study Start Date: April 2011
Study Completion Date: December 2013
Primary Completion Date: September 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: TRC105 and Bevacizumab
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.
Drug: TRC105 and Bevacizumab
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.
Other Names:
  • Chimeric Antibody (TRC105) to CD105
  • Avastin

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.
