Androgen Ablation Therapy With or Without Niraparib After Radiation Therapy for the Treatment of High-Risk Localized or Locally Advanced Prostate Cancer

This phase II trial studies the effect of androgen ablation therapy with or without niraparib after standard of care radiation therapy in treating patients with prostate cancer that has not spread to other parts of the body (localized) or that has spread to nearby tissue or lymph nodes (locally advanced). Androgen ablation therapy (also known as hormone therapy) lowers the levels of male hormones called androgens in the body. Androgens stimulate prostate cancer cells to grow. There are 2 types of androgen ablation therapy given in this study: AAP + ADT and Apa + ADT. AAP + ADT is the treatment combination of the drugs abiraterone acetate and prednisone (AAP) given with androgen deprivation therapy (ADT, also known as androgen deprivation therapy or androgen suppression medication, which is used as standard of care to lower testosterone levels in men with high risk localized or metastatic prostate cancer). Apa + ADT is the treatment combination of the drug apalutamide (Apa) given with ADT. Androgen ablation therapy with or without niraparib after radiation therapy may help to control the disease in patients with prostate cancer.

Proton Radiation Therapy for the Treatment of Patients With High Risk Prostate Cancer

This phase II trial investigates whether proton radiation therapy directed to the prostate tumor, pelvic, and para-aortic lymph nodes, is an effective way to treat patients with high-risk or lymph node positive prostate cancer who are receiving radiation therapy, and if it will result in fewer gastrointestinal and genitourinary side effects. Proton beam therapy is a new type of radiotherapy that directs multiple beams of protons (positively charged subatomic particles) at the tumor target, where they deposit the bulk of their energy with essentially no residual radiation beyond the tumor. By reducing the exposure of the healthy tissues and organs to radiation in the treatment of prostate cancer, proton therapy has the potential to better spare healthy tissue and reduce the side effects of radiation therapy.

RElugolix VErsus LeUprolide Cardiac Trial

This clinical trial investigates the impact of prostate cancer treatment, specifically androgen deprivation therapy (ADT), on the heart and coronary vessels among men with localized, non-metastatic prostate cancer undergoing definitive radiation therapy and concomitant ADT. Recently, cardiovascular toxicity from hormone therapy that is routinely used for prostate cancer (e.g. leuprolide) has emerged as a concern, yet studies identifying who is at risk and the mechanism of cardiac damage are lacking. Additionally, a new hormone therapy drug, relugolix, has recently been Food and Drug Administration (FDA)-approved and may reduce toxicity to the heart. This trial intends to investigate the mechanism of cardiovascular toxicity from ADT, investigate the mechanism by which relugolix reduces cardiovascular toxicity, and identify predictive biomarkers to improve individualized risk-assessment for cardiovascular toxicity from ADT.

Carboplatin Chemotherapy Before Surgery for People With High-Risk Prostate Cancer and an Inherited BRCA1 or BRCA2 Gene Mutation

This phase II trial tests how well carboplatin before surgery works in treating patients with high-risk prostate cancer and an inherited BRCA1 or BRCA2 gene mutation. Carboplatin is in a class of medications known as platinum-containing compounds. It works in a way similar to the anticancer drug cisplatin, but may be better tolerated than cisplatin. Carboplatin works by killing, stopping, or slowing the growth of tumor cells. Giving carboplatin before surgery may shrink tumors in patients with high-risk prostate cancer with BRCA1 and BRCA2 gene mutations.

PI3Kbeta Inhibitor AZD8186 and Docetaxel in Treating Patients Advanced Solid Tumors With PTEN or PIK3CB Mutations That Are Metastatic or Cannot Be Removed by Surgery

This phase I trial studies the side effects and best dose of PI3Kbeta inhibitor AZD8186 when given together with docetaxel in treating patients with solid tumors with PTEN or PIK3CB mutations that have spread to other places in the body (metastatic) or cannot be removed by surgery. PI3Kbeta inhibitor AZD8186 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as docetaxel, 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. Giving PI3Kbeta inhibitor AZD8186 and docetaxel may work better in treating patients with solid tumors.

Aspirin and Rintatolimod With or Without Interferon-alpha 2b in Treating Patients With Prostate Cancer Before Surgery

This phase II trial studies how well enteric-coated (EC) aspirin and rintatolimod with or without interferon-alpha 2b work in treating patients with prostate cancer before surgery. EC Aspirin may help to keep the prostate cancer from coming back. Rintatolimod may stimulate the immune system and interfere with the ability of tumor cells to grow and spread. Interferon-alpha 2b may improve the body's natural response to infections and may slow tumor growth. It is not yet known how well rintatolimod, EC aspirin, and interferon-alpha 2b work in treating patients with prostate cancer undergoing surgery.

High Dose-Rate Brachytherapy and Stereotactic Body Radiotherapy for the Treatment of Prostate Adenocarcinoma

This phase II trial investigates the effect of high dose-rate brachytherapy and stereotactic body radiotherapy in treating patients with prostate adenocarcinoma. Brachytherapy, also known as internal radiation therapy, uses radioactive material placed directly into or near a tumor to kill tumor cells. Stereotactic body radiation therapy uses special equipment to position a patient and deliver radiation to tumors with high precision. This method may kill tumor cells with fewer doses over a shorter period and cause less damage to normal tissue.

Extending Prostate Genetic Awareness, Navigation, and Delivery: The EXPAND Network

This trial evaluates whether a network of peer genetic coaches is useful for addressing disparities in genetic testing and screening among African American men with prostate cancer that has spread from where it first started (primary site) to other places in the body (metastatic). While genetic testing has become central to prostate cancer care, African American men are less likely seek testing due to lack of awareness, cultural beliefs, financial limitations, fear of discrimination, and mistrust in the healthcare system. A network of peer genetic coaches may help address barriers, beliefs, and needs of African American men in the community and provide navigation to increase engagement in genetic testing.
