In this Phase I/II clinical trial, the investigators seek to pilot the addition of hydroxychloroquine (HCQ) to the standard front-line therapy of colorectal cancer, FOLFOX/bevacizumab. In toxicity terms, the investigators previous studies lead them to believe that a full dose (800mg) of HCQ will be well-tolerated in this setting. By starting at 600 mg, the investigators will ensure that the full dose is approached with an eye to safety, and if needed, the investigators will use the lower dose. Both doses achieve autophagy inhibition in our current studies.
