Summary: this phase i trial studies the side effects and best dose of trametinib and trifluridine and tipiracil hydrochloride in treating patients with colon or rectal cancer that has spread to other places in the body (advanced/metastatic) or cannot be removed by surgery. trametinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. drugs used in chemotherapy, such as trifluridine and tipiracil hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. giving trametinib and trifluridine and tipiracil hydrochloride may prevent cancer cells from dividing and work better in treating patients with colon and rectal cancer.

primary objectives: i. determine the maximum tolerated dose (mtd) for the combination of trametinib and trifluridine and tipiracil hydrochloride (tas-102) in patients with chemotherapy-resistant metastatic colorectal cancer. secondary objectives: i. describe the safety of the combination of trametinib and tas-102 across all investigated dose levels. ii. describe the clinical activity including objective response rate (orr), progression-free survival (pfs), and overall survival (os) of the combination in an expansion cohort using response evaluation criteria in solid tumors (recist) 1.1 criteria. outline: patients receive trifluridine and tipiracil hydrochloride orally (po) twice daily (bid) on days 1-5 and 8-12 and trametinib po once daily (qd) on days 1-28. cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. after completion of study treatment, patients are followed up at 30 days and then bi-annually thereafter.
