Designing a Dyad-Based mHealth Intervention to Improve Adherence to Lifestyle Recommendations in Colorectal Cancer Survivors and Their Family Caregivers

This clinical trial develops and tests a mobile health (mHealth) intervention to improve adherence to lifestyle recommendations in colorectal cancer (CRC) survivors and their family caregivers. The current challenge for cancer survivorship is identifying novel approaches to help adhere to the lifestyle recommendations that have been shown to improve symptom burden, health outcomes, and health-related quality of life (HRQoL). The development of a digital health intervention specifically for CRC survivors and family caregivers may improve adherence to the American Cancer Society Nutrition and Physical Activity Guideline for Cancer Survivors and improve family health.

Testing the Combination of Two Anti-cancer Drugs, DS-8201a and AZD6738, for The Treatment of Advanced Solid Tumors Expressing the HER2 Protein or Gene, The DASH Trial

The dose escalation phase of this trial identifies the safety, side effects and best dose of ceralasertib (AZD6738) when given in combination with trastuzumab deruxtecan (DS-8201a) in treating patients with solid tumors that have a change (mutation) in the HER2 gene or protein and have spread to other places in the body (advanced). The dose expansion phase (phase Ib) of this trial compares how colorectal and gastroesophageal cancers with HER2 mutation respond to treatment with a combination of ceralasertib and trastuzumab deruxtecan versus trastuzumab deruxtecan alone. Ceralasertib may stop the growth of tumor cells and may kill them by blocking some of the enzymes needed for cell growth. Trastuzumab deruxtecan is a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called deruxtecan. Trastuzumab attaches to HER2 positive cancer cells in a targeted way and delivers deruxtecan to kill them. Ceralasertib and trastuzumab deruxtecan may be safe, tolerable and effective in treating patients with advanced solid tumors expressing the HER2 protein or gene.

Testing the Addition of Nivolumab to Standard Treatment for Patients With Metastatic or Unresectable Colorectal Cancer That Have a BRAF Mutation

This phase II trial tests whether adding nivolumab to the usual treatment (encorafenib and cetuximab) works better than the usual treatment alone to shrink tumors in patients with colorectal cancer that has spread to other places in the body (metastatic) or that cannot be removed by surgery (unresectable) and whose tumor has a mutation in a gene called BRAF. Encorafenib is in a class of medications called kinase inhibitors. It is used in patients whose cancer has a certain mutation (change) in the BRAF gene. It works by blocking the action of mutated BRAF that signals cancer cells to multiply. This helps to stop or slow the spread of cancer cells. Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of cancer cells. This may help keep cancer cells from growing. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving nivolumab in combination with encorafenib and cetuximab may be more effective than encorafenib and cetuximab alone at stopping tumor growth and spreading in patients with metastatic or unresectable BRAF-mutant colorectal cancer.

Zanidatamab Before Surgery for the Treatment of HER2 Positive Colon and Rectal Cancer in Patients Planned for Curative Intent Treatment

This phase II trial studies how well giving zanidatamab before surgery (neoadjuvant) works in treating patients with colon and rectal cancer that is human epidermal growth factor receptor 2 positive (HER2+ve) who are planned for curative intent treatment. Zanidatamab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. A monoclonal antibody is a type of protein that can bind to certain targets in the body, such as molecules that cause the body to make an immune response (antigens).

Combination Chemotherapy With or Without Atezolizumab in Treating Patients With Stage III Colon Cancer and Deficient DNA Mismatch Repair

This phase III trial studies combination chemotherapy and atezolizumab to see how well it works compared with combination chemotherapy alone in treating patients with stage III colon cancer and deficient deoxyribonucleic acid (DNA) mismatch repair. Drugs used in combination chemotherapy, such as oxaliplatin, leucovorin calcium, and fluorouracil, 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. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving combination chemotherapy with atezolizumab may work better than combination chemotherapy alone in treating patients with colon cancer.

Testing the Use of BRAF-Targeted Therapy After Surgery and Usual Chemotherapy for BRAF-Mutated Colon Cancer

This phase II/III trial compares treatment with encorafenib and cetuximab to usual care (patient observation) for reducing the chance of cancer recurrence after standard surgery and chemotherapy in patients with BRAF-mutated stage IIB-III colon cancer. Encorafenib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Cetuximab is in a class of medications called monoclonal antibodies. It binds to a protein called EGFR, which is found on some types of tumor cells. This may help keep tumor cells from growing. Giving encorafenib and cetuximab after standard surgery and chemotherapy may be more effective at reducing the chance of cancer recurrence compared to the usual patient observation.

SX-682 and Nivolumab for the Treatment of RAS-Mutated, MSS Unresectable or Metastatic Colorectal Cancer, the STOPTRAFFIC-1 Trial

This phase Ib/II trial studies the side effects and best dose of SX-682 that can be given alone and in combination with nivolumab in treating patients with RAS-Mutated, microsatellite stable (MSS) colorectal cancer that has spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable). SX-682 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as nivolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving SX-682 alone and together with nivolumab may kill more tumor cells.

Family Communications After Genetic Testing

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.

Panitumumab, Regorafenib, or TAS-102, in Treating Patients With Metastatic and/or Unresectable RAS Wild-Type Colorectal Cancer

This phase II trial studies how well retreatment with panitumumab works compared to standard of care regorafenib or trifluridine and tipiracil hydrochloride (TAS-102) in treating patients with colorectal cancer that is negative for RAS wild-type colorectal cancer has spread to other places in the body (metastatic), and/or cannot be removed by surgery (unresectable), and is negative for resistance mutations in blood. Treatment with panitumumab may interfere with the ability of tumor cells to grow and spread. Some tumors need growth factors to keep growing. Growth factor antagonists, such as regorafenib, may interfere with the growth factor and stop the tumor from growing. Drugs used in chemotherapy, such as TAS-102, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving panitumumab may work better in treating patients with colorectal cancer than with the usual treatment of regorafenib or TAS-102.
