Modulation of autophagy: a Phase II study of vorinostat plus hydroxychloroquine versus regorafenib in chemotherapy-refractory metastatic colorectal cancer (mCRC).

ABSTRACT:

Background

In metastatic colorectal cancer (mCRC), regorafenib (RGF), a multi-kinase inhibitor with angiogenic inhibition has modest effects on survival. We reported that autophagy modulation using hydroxychloroquine (HCQ), enhances the anticancer activity of the histone deacetylase inhibitor, vorinostat (VOR), in mCRC, is well tolerated, and has comparable activity to RGF. Thus, we conducted a prospective study of VOR/HCQ versus RGF in mCRC.

Methods

This is a randomised, controlled trial of VOR 400 mg and HCQ 600 mg orally daily versus RGF 160 mg orally daily (3 weeks on/1 week off), every 4 weeks, in patients with mCRC.

Primary endpoint

median progression-free survival (mPFS). Secondary endpoints: median overall survival (mOS); adverse events; pharmacodynamic analys
