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

A Study to Compare Darolutamide Given With Androgen Deprivation Therapy (ADT) With ADT in Men With Hormone Sensitive Prostate Cancer and Raise of Prostate Specific Antigen (PSA) Levels After Local Therapies
Recruiting
Researchers are looking for a better way to treat men at high-risk of biochemical recurrence (BCR) of prostate cancer. BCR means that in men who had prostate cancer and were treated by either surgery and/ or radiation therapy, the blood level of a specific protein called PSA rises. PSA is a marker of prostate cancer cells activity. The PSA increase means that the cancer has come back even though conventional imaging such as computed tomography (CT) scans, magnetic resonance imaging (MRI) and bo... Read More

Palbociclib and Binimetinib in RAS-Mutant Cancers, A ComboMATCH Treatment Trial
Recruiting
This phase II ComboMATCH treatment trial evaluates the effectiveness of palbociclib and binimetinib in treating patients with RAS-mutated cancers. Palbociclib and binimetinib are both in a class of medications called kinase inhibitors. They work by blocking the action of abnormal proteins that signals cancer cells to multiply. This trial may help researchers understand if giving the combination of palbociclib and binimetinib can help improve the amount of time before the cancer grows in patients... Read More

Testing the Use of the Combination of Selumetinib and Olaparib or Selumetinib Alone Targeted Treatment for RAS Pathway Mutant Recurrent or Persistent Ovarian and Endometrial Cancers, A ComboMATCH Treatment Trial
Recruiting
This phase II ComboMATCH treatment trial compares selumetinib plus olaparib to selumetinib alone in women with endometrial or ovarian (fallopian tube and primary peritoneal) cancer that has come back (recurrent) or that remains despite treatment (persistent) and harbors a mutation in the RAS pathway. Selumetinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Olaparib is an inhibitor of PARP, an enzyme that helps repair deoxyribonucleic acid (DNA) when... Read More
