Modulation of Autophagy: A Clinical Study of Vorinostat Plus Hydroxychloroquine Versus Regorafenib in Refractory Metastatic Colorectal Cancer (mCRC) Patients (CTMS# 14-2015)
The investigators will give VOR 400 mg PO daily and HCQ 600 mg PO daily in 4-week cycles. Patients will require imaging up to 6 weeks prior to enrollment and will be assessed for measureable evidence of mCRC. This will be a randomized, controlled phase II clinical trial of patients with histological documentation of metastatic colorectal cancer, who have received locally and currently approved standard therapies, excluding RGF. Patients will be randomized 1:1 to RGF or VOR/HCQ (see schema below). Also, crossover is optional after first progression on the initial therapy, and based on physician discretion and in the best interest of the patient. If crossover is not done, then the patient will be off study and can go on to receive other treatments.
