MicroOrganoSphere (MOS) Drug Screen Pilot Trial in Colorectal Cancer

Patient-derived models of cancer, called MOS, will be generated from a biopsy of a subject's adenocarcinoma of the colon and/or rectum that is metastatic to the liver and a drug screen using standard-of-care drugs used will be completed (oxaliplatin, irinotecan, 5-FU/capecitabine (Xeloda), bevacizumab, panitumumab or cetuximab, trifluridine/tipiracil (Lonsurf), regorafenib and pembrolizumab or nivolumab). Subjects will receive standard-of-care therapy for CRC dictated by their treating physicians.
