Stage IV Colon Cancer AJCC v8

This clinical trial compares patient (proband)-mediated communication to provider-mediated communication for improving genetic testing in first-degree relatives of patients with newly diagnosed colorectal cancer. It is estimated that 30% of cases of colorectal cancer have a genetic basis and about 15% of these patients have a disease-causing (pathogenic) inherited (germline) variant in a cancer susceptibility gene. Most individuals carrying a pathogenic germline variant are unaware of their cancer risk and may not meet guidelines for genetic testing. Identifying pathogenic germline variants or hereditary cancer syndromes in cancer patients has important implications for their at-risk relatives who may not know that they are at high risk for cancer. The burden of communicating this risk to first-degree relatives often falls on the patients, who may lack sufficient knowledge to correctly share and explain their genetic test results. Receiving provider-mediated communication of genetic testing results may be more effective at communicating genetic risk to first-degree relatives than the usual practice of proband-mediated communication.

This phase Ib/II trial tests the safety and side effects of BMS-986504 in combination with pemetrexed and how well the combination works in treating patients with solid tumors with MTAP deletion and that has spread from where it first started (primary site) to other places in the body (metastatic). The MTAP gene helps cells recycle important parts needed to make deoxyribonucleic acid (DNA), which is needed for cell growth and function. MTAP deletion means that the MTAP gene is missing. BMS-986504, a PRMT5 inhibitor, may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Pemetrexed is in a class of medications called antifolate antineoplastic agents. It works by stopping cells from using folic acid to make DNA and may kill tumor cells. Giving BMS-986504 in combination with pemetrexed may be safe, tolerable, and/or effective in treating patients with metastatic solid tumors with MTAP deletion.

This phase II trial tests whether NBT-NM108 works in reducing chemotherapy-induced diarrhea in patients with colon cancer that has spread to other places in the body (metastatic). Irinotecan is one of the most used medicine for colon cancer, but it leads to diarrhea in most patients receiving it and among some of them, severe diarrhea can occur. NBT-NM108 is a high dietary fiber formula that is developed based on research findings that have shown that high fiber diets can help maintain healthy bacteria in the gut and improve gut function. Giving NBT-NM108 to patients with colon cancer receiving chemotherapy may help relieve or lessen diarrhea symptoms and lead to improved tolerance of the chemotherapy drug, irinotecan.
