This is a Phase IB/II, 2-stage, open-label, multicenter study to determine the efficacy and
safety of durvalumab in combination with novel oncology therapies (i.e. therapies designed
for immune modulation) with or without paclitaxel and durvalumab + paclitaxel as first-line
treatment in patients with metastatic triple negative breast cancer (TNBC). The study is
designed to concurrently evaluate potential novel treatment combinations with clinical
promise using a 2-stage approach. The study will use a Simon 2-Stage design to evaluate which
cohorts may proceed to expansion.
Part 1 is a Phase IB study of safety and initial efficacy, and Part 2 may expand patient
enrollment if adequate efficacy signal is observed in Part 1. The treatment regimens
evaluated in Part 2 will depend on the evaluation of safety and efficacy outcomes in Part 1.
