Study Summary

The main purpose of this study is to find the best dose of hydroxychloroquine (HCQ) when given in combination with regorafenib and entinostat.

Primary Outcome

Participants were evaluable for toxicity if they have taken one dose of HCQ and one dose of entinostat. To be considered for evaluability in a Phase I cohort in the absence of dose-limiting toxicity, patients should have completed \> 85% of HCQ doses, and at least 3 of 4 entinostat doses. The MTD will be defined as a) the dose producing DLT in 1 out of 6 patients, or b) the dose level below the dose which produced DLT in ≥ 2 out of 3 patients, or in ≥ 2 out of 6 patients. DLTs will be defined by
