Testing the Safety of the Combination of Anti-Cancer Drugs CX-5461 (Pidnarulex) and Trastuzumab Deruxtecan (T-DXd) for Human Epidermal Growth Factor Receptor 2 (HER2)-Positive Solid Tumors and Breast Cancer

This phase I trial tests the safety, side effects, and best dose of pidnarulex in combination with trastuzumab deruxtecan in treating patients with breast cancer and other solid tumors that express varying levels of a protein called HER2 and that has spread from where it first started (primary site) to other places in the body (metastatic), that cannot be removed by surgery (unresectable), or that has spread to nearby tissue or lymph nodes (locally advanced). Pidnarulex is an enzyme inhibitor that causes cell death and prevents tumor cell growth. 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. Giving pidnarulex in combination with trastuzumab deruxtecan may be safe, tolerable and/or effective in treating patients with metastatic, unresectable, or locally advanced HER2-expressing breast cancer or other solid tumors.

Targeted Therapy Directed by Genetic Testing in Treating Patients With Locally Advanced or Advanced Solid Tumors, The ComboMATCH Screening Trial

This ComboMATCH patient screening trial is the gateway to a coordinated set of clinical trials to study cancer treatment directed by genetic testing. Patients with solid tumors that have spread to nearby tissue or lymph nodes (locally advanced) or have spread to other places in the body (advanced) and have progressed on at least one line of standard systemic therapy or have no standard treatment that has been shown to prolong overall survival may be candidates for these trials. Genetic tests look at the unique genetic material (genes) of patients' tumor cells. Patients with some genetic changes or abnormalities (mutations) may benefit from treatment that targets that particular genetic mutation. ComboMATCH is designed to match patients to a treatment that may work to control their tumor and may help doctors plan better treatment for patients with locally advanced or advanced solid tumors.

Testing the Combination of the Anticancer Drugs Trastuzumab Deruxtecan (DS-8201a) and Azenosertib (ZN-c3) in Patients With Stomach or Other Solid Tumors

This phase I trial tests the safety, side effects, and best dose of azenosertib in combination with trastuzumab deruxtecan in treating patients with HER2-positive gastric or gastroesophageal junction cancer and other HER2-positive solid tumors that have spread to nearby tissue or lymph nodes (locally advanced), 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). Azenosertib is in a class of medications called kinase inhibitors. It inhibits a protein called Wee1. Inhibition of the Wee1 protein can make tumor cells more vulnerable to chemotherapy drugs, leading to tumor cell death. 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 cancer cells in a targeted way and delivers deruxtecan to kill them. Giving azenosertib in combination with trastuzumab deruxtecan may be safe, tolerable, and/or more effective in treating patients with locally advanced, metastatic, or unresectable HER2-positive gastric, gastroesophageal junction, or other solid tumors, compared to just trastuzumab deruxtecan alone.

Testing the Combination of the Anti-cancer Drugs ZEN003694 (ZEN-3694) and Talazoparib in Patients With Advanced Solid Tumors, The ComBET Trial

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.

Testing the Addition of an Anti-Cancer Drug, ZEN003694, to the Usual Chemotherapy Treatment (Capecitabine) for Metastatic or Unresectable Cancers

This phase I trial tests the safety, side effects, and best dose of ZEN003694 in combination with the usual treatment with capecitabine in treating patients with cancer that has spread from where it first started (primary site) to other places in the body (metastatic) or cannot be removed by surgery (unresectable) and that it has progressed on previous standard treatment. ZEN003694 is an inhibitor of a family of proteins called the bromodomain and extra-terminal (BET). It may prevent the growth of tumor cells that over produce BET protein. Capecitabine is in a class of medications called antimetabolites. It is taken up by cancer cells and breaks down into fluorouracil, a substance that kills cancer cells. Giving ZEN003694 in combination with capecitabine may be safe in treating patients with metastatic or unresectable solid tumors.

Testing the Combination of DS-8201a and Olaparib in HER2-Expressing Cancers With Expansion in Patients With Platinum Resistant Ovarian Cancer

This phase I trial identifies the side effects and best dose of DS-8201a and olaparib in treating patients with HER2-expressing cancers that have spread to other places in the body or cannot be removed by surgery or ovarian cancer that remains despite treatment with a platinum treatment (platinum resistant). Olaparib is a drug that blocks an enzyme involved in many cell functions, including the repair of deoxyribonucleic acid (DNA) damage. Blocking this enzyme may help keep tumor cells from repairing their damaged DNA, causing them to die. DS-8201a is an antibody-drug conjugate. This agent has two components: an antibody component and a chemotherapy component. The antibody component is attached to the chemotherapy molecules. Upon administration of DS-8201a, the antibody targets and binds to tumor cells that have abundant HER2 (human-epidermal growth factor receptor 2), which is a protein on the surface of some tumor cells. The chemotherapy then enters the cells and blocks DNA replication in the tumor cells with abundant HER2, causing them to die. Giving DS-8201a and olaparib may shrink or stabilize the cancer.

Low Dose, Reduced Frequency Nivolumab for the Treatment of Unresectable or Metastatic Cancer, AFFORD IO Trial

This phase II trial studies how well low dose, reduced frequency nivolumab works in treating patients with cancer that cannot be removed by surgery (unresectable) or that has spread from where it first started (primary site) to other places in the body (metastatic). 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. Nivolumab is a type of immune checkpoint inhibitor (ICI). ICIs have revolutionized the treatment of numerous cancers with remarkable improvement in participant outcomes. However, accessibility of ICIs is extremely poor on a global scale, mainly due to high costs. Previous research has suggested that these drugs can be given at lower doses and reduced frequency than their approved dosing regimens, with similar results. Giving nivolumab at a lower dose and less often may help reduce the cost of therapy, improve immunotherapy accessibility, and therefore improve survival outcomes globally.
