Brief summary: This phase II trial studies how well binimetinib and palbociclib work compared to TAS-102 in treating patients with KRAS and NRAS mutation positive colorectal cancer that has spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable). Binimetinib and palbociclib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as TAS-102, 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 binimetinib and palbociclib may work better compared to TAS-102 alone in treating patients with colorectal cancer.

Detailed description: PRIMARY OBJECTIVE:

I. The primary objective is to compare the progression-free survival (PFS) between those randomized to palbociclib/binimetinib and those randomized to trifluridine and tipiracil hydrochloride (TAS-102) in patients with refractory KRAS- or NRAS-mutant metastatic colorectal cancer (CRC).

SECONDARY OBJECTIVES:

I. To compare the overall response rate by Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 criteria between those randomized to palbociclib/binimetinib and those randomized to TAS-102 in patients with refractory KRAS- or NRAS-mutant metastatic CRC.

II. To compare the overall survival (OS) between those randomized to palbociclib/binimetinib and those randomized to TAS-102 in patients with refractory KRAS- or NRAS-mutant metastatic CRC.

III. To determine the safety and tolerability of the recommended phase II dose of palbociclib in combination with binimetinib in patients with refractory KRAS- or NRAS-mutant metastatic CRC.

CORRELATIVE RESEARCH OBJECTIVES:

I. To determine the tumor mutational profiles that characterize groups of patients that predict for response or resistance to combination of palbociclib/binimetinib.

II. To determine the correlation between circulating tumor deoxyribonucleic acid (DNA) and tumor response or resistance to therapy with palbociclib/binimetinib or TAS-102.

III. To determine the association between Consensus Molecular Subtype based on gene expression profiling and response or resistance to combination of palbociclib/binimetinib.

OUTLINE: Patients are randomized to 1 of 2 arms.

ARM A: Patients receive binimetinib orally (PO) twice daily (BID) on days 1-28 and palbociclib PO once daily (QD) on days 1-21. Treatment repeats every 28 days for up to 24 cycles in the absence of disease progression or unacceptable toxicity.

ARM B: Patients receive trifluridine and tipiracil hydrochloride PO BID on days 1-5 and 8-12. Treatment repeats every 28 days for up to 24 cycles in the absence of disease progression or unacceptable toxicity. Patients with disease progression may optionally crossover to Arm A.

After completion of study treatment, patients are followed up within 30-37 days and then every 12 weeks for up to 24 months.
