What was measured

A DLT was defined as the occurrence of any of the protocol-specified toxicities occurring up to and including Day 28 for the cohorts where mFOLFOX6 and nab-paclitaxel/gemcitabine are administered and Day 21 for all other chemotherapy regimens in Phase 1, except those with a clear alternative explanation (eg, disease progression) or transient (≤ 72 hours) abnormal laboratory values without associated clinically significant signs or symptoms based on investigator determination.

Analysis population: The safety population included all participants enrolled in the study who received at least 1 dose of epacadostat, pembrolizumab, or an applicable chemotherapy regimen.

Group B: Epa + Pembrolizumab + Nab-Paclitaxel and Gemcitabine

Epa (100 mg) oral BID continuous daily dosing at the protocol-defined dose in combination with pembrolizumab (200 mg) IV in combination with nab-paclitaxel IV and gemcitabine IV.
