Study Summary

Primary objective is to assess the efficacy of combined Indoleamine 2,3-dioxygenase (IDO) and PD-1 inhibition in a single arm phase II trial of epacadostat and pembrolizumab in patients with advanced imatinib-refractory GIST, using a primary endpoint of overall response rate. Secondary objectives are to evaluate the progression free survival (PFS), the overall survival (OS), the response rate and to evaluate the safety and tolerability of combined epacadostat and pembrolizumab treatment. The investigator hypothesizes that treatment with epacadostat and pembrolizumab will increase the response rate compared to what has been historically achieved with salvage tyrosine kinase inhibitors.

Primary Outcome

The primary endpoint is the overall response rate as defined as the best response using RECIST v1.1 criteria. A standard way to measure how well a cancer patient responds to treatment. It is based on whether tumors shrink, stay the same, or get bigger. To use RECIST, there must be at least one tumor that can be measured on x-rays, CT scans, or MRI scans. The types of response a patient can have are a complete response (CR), a partial response (PR), progressive disease (PD), and stable disease (S
