Unresectable Malignant Solid Neoplasm clinical trials at UC Davis

This phase I trial tests the safety, side effects, and best dose of neratinib in combination with trastuzumab deruxtecan in treating patients with solid tumors that have spread from where it first started (primary site) to other places in the body (metastatic) or that cannot be removed by surgery (unresectable), and have changes in a gene called human epidermal growth factor receptor 2 (HER2). Neratinib is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals tumor cells to multiply. This helps slow or stop the spread of tumor cells. Trastuzumab deruxtecan is in a class of medications called antibody-drug conjugates. It is composed of a monoclonal antibody, called trastuzumab, linked to a chemotherapy drug, called deruxtecan. Trastuzumab attaches to HER2 positive tumor cells in a targeted way and delivers deruxtecan to kill them. Adding neratinib to trastuzumab deruxtecan may be able to shrink cancer with a change in the HER2 gene.

This phase I trial studies the side effects and best dose of M6620 and irinotecan hydrochloride in treating patients with solid tumors that have spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable). M6620 and irinotecan hydrochloride may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

This phase I trial studies the side effects and best dose of pembrolizumab and recombinant interleukin-12 in treating patients with solid tumors. Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Recombinant interleukin-12 may kill tumor cells by blocking blood flow to the tumor and by stimulating white blood cells to kill tumor cells. Giving pembrolizumab and recombinant interleukin-12 may work better than giving pembrolizumab alone in treating patients with solid tumors.

This phase I/II trial studies the best dose and side effects of peposertib and to see how well it works with avelumab and hypofractionated radiation therapy in treating patients with solid tumors and hepatobiliary malignancies that have spread to other places in the body (advanced/metastatic). Peposertib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Immunotherapy with monoclonal antibodies, such as avelumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Hypofractionated radiation therapy delivers higher doses of radiation therapy over a shorter period of time and may kill more tumor cells and have fewer side effects. Giving peposertib in combination with avelumab and hypofractionated radiation therapy may work better than other standard chemotherapy, hormonal, targeted, or immunotherapy medicines available in treating patients with solid tumors and hepatobiliary malignancies.

This phase II trial tests whether ZEN003694 (ZEN-3694) in combination with talazoparib works to shrink tumors in patients with solid tumors that are unlikely to be cured or controlled with treatment and that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Another aim of this study is to find out if, and how, patients' genes influence their response to this specific drug combination. For this part of the study, investigators will run tests using samples of patients' tumor tissue and blood that will be collected during the study. ZEN-3694 is an inhibitor of a family of proteins called the bromodomain and extra-terminal (BET). It may prevent the growth of tumor cells that overproduce BET protein. Talazoparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when it becomes damaged. Blocking PARP may help keep cancer cells from repairing their damaged DNA, causing them to die. PARP inhibitors are a type of targeted therapy. Genes are pieces of the DNA code that individuals inherit from their parents. Some genes work to protect against cancer by correcting damage that can occur in the DNA when cells divide. BRCA1 and BRCA2 are two examples of these types of genes, and they are called tumor-suppressor genes. For example, if a person has a mutation in a BRCA1/2 gene they have a greatly increased risk of developing breast and ovarian cancer because their cells may no longer be able to completely repair damaged DNA. It is the accumulation of DNA damage which causes a cell to change into a cancerous cell. Other genes are also involved in this process, and these are called DNA damage repair genes. The KRAS mutation is a change in a protein in normal cells. Normally KRAS serves as an information hub for signals in the cell that lead to cell growth, but when there is a mutation in KRAS it signals too much and cells grow without being told to, which causes cancer. Combination therapy with ZEN-3694 and talazoparib may be effective at slowing or stopping tumor growth in patients with advanced cancer.
