SECONDARY outcome

Timeframe: 1.5 years

Population: All patients who received at least a portion of a dose of TRC105

Serial blood samples will be tested for anti-drug antibody (ADA) immune response to TRC105. Patients who are positive at baseline (prior to receiving TRC105) are excluded from analysis.

SECONDARY outcome

Timeframe: 1.5 years

Population: Patients who had measurable disease at baseline and received at least one follow up scan were evaluable for the primary efficacy outcome of ORR by RECIST 1.1

The best response according to RECIST 1.1 for each patient with measurable disease who received at least one dose of study drug will be listed by cohort and tumor type
