Evaluate the proportion of patients in each arm who complete 2 cycles of treatment and who intend to initiate cycle 3 if no progression is noted on the planned 8-week scan.
This randomized phase II trial studies how well lower-dose compared to standard dose regorafenib works in treating patients with colorectal cancer that has spread from the primary site (place where it started) to other places in the body and does not respond to treatment. Regorafenib may stop the growth of colorectal cancer by blocking the growth of new blood vessels necessary for tumor growth and by blocking some of the enzymes needed for cell growth. It is not yet known whether lower-dose or standard dose regorafenib is more effective in treating patients with colorectal cancer. Clobetasol propionate is a steroid cream that is commonly used to treat a variety of skin conditions and may help prevent hand-foot skin reactions in patients receiving regorafenib.
