3 Clinical Trials for Various Conditions
This phase II trial tests how well atezolizumab works in combination with tiragolumab in treating patients with rare solid tumors that may have spread from where they first started to nearby tissue, lymph nodes, or distant parts of the body (advanced stage). Immunotherapy with monoclonal antibodies, such as atezolizumab and tiragolumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. The study biopsy takes small pieces of cancer tissue from a tumor. The purpose of these biopsies is to compare the body's immune response against the tumor before and after treatment with the study drugs. Blood samples will also be collected for the study. The researchers will use the samples to learn more about how atezolizumab and tiragolumab work and which patients in the future might be most likely to respond to atezolizumab and tiragolumab. Using atezolizumab in combination with tiragolumab may help to shrink tumors in patients diagnosed with advanced stage rare solid-tumor cancers.
This phase II trial tests whether combination of talazoparib and temozolomide works to shrink tumors in patients with rare cancer that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Talazoparib is an inhibitor of poly adenosine diphosphate-ribose polymerase (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. Temozolomide is in a class of medications called alkylating agents. It damages the cell's DNA and may kill cancer cells. Giving talazoparib in combination with temozolomide may help shrink advanced rare cancers or stop them from growing.
This phase II trial studies how well pembrolizumab works in treating patients with rare tumors that cannot be removed by surgery or have spread to other parts of the body. Monoclonal antibodies, such as pembrolizumab, may block specific proteins found on white blood cells which may strengthen the immune system and control tumor growth.
