This study is for participants that have colorectal cancer that has been treated before, spread to other parts of the body and they test positive for a protein called PD-L1. PD-L1 is a protein that helps keep T cells from killing other cells, including cancer cells. This study drug (MK-4280A) is used to block this protein so the "brakes" on the immune system are released and the ability of T cells to kill cancer cells is increased. MK-4280A is a mixture of 2 drugs: MK-4280 (favezelimab) and MK-3475 (pembrolizumab also called pembro). MK-4280A has not been approved by the United States Food and Drug Administration (FDA). This purpose of this study is to assess the safety and efficacy of coformulated favezelimab/pembrolizumab (MK-4280A) and to compare MK-4280A with the standard of care treatment of regorafenib and TAS-102 (trifluridine and tipiracil). Participants will be randomized to one of two groups. Group 1 will get MK-4280A and Group 2 will get a standard treatment. This study has 3 phases: Screeing (about 1 month), Treatment (depends on which drug the participant gets, how well their cancer is controlled, and how they are feeling) and Follow-up (1 visit 30 days after the last dose of study drug, then every 9 weeks, then the study team will contact you every 12 weeks). Participants may experience certain side effects and discomforts from taking the study drug. Because the study drug is experimental, all the side effects may not be known.
This study is for patients receiving oxaliplatin for their cancer treatment. The study is being done to see if duloxetine (either 30 mg or 60 mg) prevents numbness, tingling, and/or pain caused by your cancer treatment with oxaliplatin. The study is being done to see if duloxetine can prevent OIPN (oxaliplatin-induced peripheral neuropathy).
This study is for patients with previously untreated metastatic colorectal cancer. The purpose of the study is to see if adding a new drug to the usual combination of drugs can lower the chance of the colorectal cancer growing or spreading.
