Study Summary

This is an open-label, non-randomized, single-institution, single arm Phase II study conducted using a Simon two-stage design with an additional safety lead-in. The overall objective is to determine the efficacy of combination doxorubicin with dual checkpoint blockade with anti-CTLA-4 antibody AGEN1884 and anti-PD-1 antibody AGEN2034. The investigators will estimate the progression-free survival rate at 6 months (PFS6mo) of doxorubicin plus AGEN1884/AGEN2034 in comparison to historical PFS6mo with doxorubicin monotherapy, calculated as the mean from two large randomized Phase 3 clinical trials.

Primary Outcome

Determine the progression-free survival rate at 6 months of combination therapy with doxorubicin, AGEN1884, and AGEN2034 in anthracycline-naïve patients with advanced or metastatic soft tissue sarcomas.
