Magnetic Resonance-Guided Stereotactic Body Radiation Therapy for the Treatment of Prostate Cancer

This clinical trial studies the side effects and how well magnetic resonance (MR)-guided stereotactic body radiation therapy (SBRT) works in treating patients with prostate cancer. SBRT is a type of external radiation therapy that uses special equipment to position a patient and precisely deliver radiation to tumors in the body (except the brain). The total dose of radiation is divided into smaller doses given over several days. This type of radiation therapy helps spare normal tissue. MR-guided SBRT uses magnetic resonance imaging (MRI) to define and localize the area to be treated, which may help provide more accurate delivery of SBRT and lower side effects. MR-guided SBRT may be safe, tolerable, and/or effective in treating patients with prostate cancer.

Two Studies for Patients With High Risk Prostate Cancer Testing Less Intense Treatment for Patients With a Low Gene Risk Score and Testing a More Intense Treatment for Patients With a High Gene Risk Score, The PREDICT-RT Trial

This phase III trial compares less intense hormone therapy and radiation therapy to usual hormone therapy and radiation therapy in treating patients with high risk prostate cancer and low gene risk score. This trial also compares more intense hormone therapy and radiation therapy to usual hormone therapy and radiation therapy in patients with high risk prostate cancer and high gene risk score. Apalutamide may help fight prostate cancer by blocking the use of androgen by the tumor cells. Radiation therapy uses high energy rays to kill tumor cells and shrink tumors. Giving a shorter hormone therapy treatment may work the same at controlling prostate cancer compared to the usual 24 month hormone therapy treatment in patients with low gene risk score. Adding apalutamide to the usual treatment may increase the length of time without prostate cancer spreading as compared to the usual treatment in patients with high gene risk score.

Testing the Addition of the Drug Apalutamide to the Usual Hormone Therapy and Radiation Therapy After Surgery for Prostate Cancer, INNOVATE Trial

This phase III trial studies whether adding apalutamide to the usual treatment improves outcome in patients with lymph node positive prostate cancer after surgery. Radiation therapy uses high energy x-ray to kill tumor cells and shrink tumors. Androgens, or male sex hormones, can cause the growth of prostate cancer cells. Drugs, such as apalutamide, may help stop or reduce the growth of prostate cancer cell growth by blocking the attachment of androgen to its receptors on cancer cells, a mechanism similar to stopping the entrance of a key into its lock. Adding apalutamide to the usual hormone therapy and radiation therapy after surgery may stabilize prostate cancer and prevent it from spreading and extend time without disease spreading compared to the usual approach.

Time-Restricted Eating Versus Nutritional Counseling for the Reduction of Radiation or Chemoradiation Tx Side Effects in Patients With Prostate, Cervical, or Rectal Cancers

This phase II trial studies how well time-restricted eating works in reducing side effects of radiation or chemoradiation side effects when compared to nutritional counseling among patients with prostate, cervical, and rectal cancers. Time-restricted eating, also called short term fasting or intermittent fasting, is an eating plan that alternates between not eating food (fasting) and non-fasting periods. Nutritional counseling involves being asked to follow a healthy, balanced diet that includes instructions on what kinds of food are better tolerated during radiation and chemoradiation therapy. This trial may help researchers determine if certain diets may improve the anti-cancer effects of radiation therapy and reduce the side-effects of this treatment. If successful, these diets may be integrated into the future treatment of prostate, cervical, and rectal cancers.

Abemaciclib Before 177Lu-PSMA-617 for the Treatment of Metastatic Castrate Resistant Prostate Cancer

This phase I/II trial tests the safety, side effects, and best dose of abemaciclib and whether it works before 177Lu-PSMA-617 in treating patients with castration resistant prostate cancer that has spread to other places in the body (metastatic). Abemaciclib is in a class of medications called kinase inhibitors. It is highly selective inhibitors of cyclin-dependent kinase 4 and 6, which are proteins involved in cell differentiation and growth. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. Radioligand therapy uses a small molecule (in this case 177Lu-PSMA-617), which carries a radioactive component to destroys tumor cells. When 177Lu-PSMA-617 is injected into the body, it attaches to the prostate-specific membrane antigen (PSMA) receptor found on tumor cells. After 177Lu-PSMA-617 attaches to the PSMA receptor, its radiation component destroys the tumor cell. Giving abemaciclib before 177Lu-PSMA-617 may help 177Lu-PSMA-617 kill more tumor cells.

ZEN-3694, Enzalutamide, and Pembrolizumab for the Treatment of Metastatic Castration-Resistant Prostate Cancer

This phase II trial investigates how well ZEN-3694, enzalutamide, and pembrolizumab work in treating patients with castration-resistant prostate cancer that has spread to other places in the body (metastatic). ZEN-3694 blocks the expression of the MYC gene to prevent cellular growth in certain types of tumors, including castrate resistant prostate cancer. Enzalutamide has been shown to block testosterone from reaching prostate cancer cells by binding to a receptor on prostate cancer cells, called androgen receptors. This works similar to a lock and key. When enzalutamide (key) inserts into the androgen receptor (lock) testosterone cannot attach to the androgen receptor, which slows the growth of tumor cells and may cause them to shrink. Pembrolizumab is a monoclonal antibody (proteins that can protect the body from foreign organisms, such as bacteria and viruses) designed to block a specific control switch which may be activated by tumor cells to overcome the body's natural immune system defenses. It also enhances the activity of the body's immune cells against tumor cells. The purpose of this study is to find out the effects ZEN-3694, enzalutamide, and pembrolizumab on patients with metastatic castration-resistant prostate cancer who have previously experienced disease progression.

Extremely Hypofractionated Intensity Modulated Stereotactic Body Radiotherapy for the Treatment of Prostate Cancer With Rising PSA After Radical Prostatectomy

This phase II trial investigates the effect of extremely hypofractionated intensity modulated stereotactic body radiotherapy in treating patients with prostate cancer that has rising prostate specific antigen (PSA) after radical prostatectomy. 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. 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.

Testing the Addition of a New Anti-Cancer Drug, Niraparib, to the Usual Treatment (Hormone and Radiation Therapy) for Prostate Cancer With a High Chance of Recurring

This is a phase I-II trial to find the safety and activity of adding a new drug (neraparib) to the usual treatment (radiation combined with male hormone deprivation therapy) in lowering the chance of prostate cancer growing or returning. Niraparib 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. Adding niraparib to the usual care may lower the chance of prostate cancer growing or returning.

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.

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.

Cryoablation Combined With Stereotactic Body Radiation Therapy for the Treatment of Painful Bone Metastases, the CROME Trial

This trial compares cryoablation combined with stereotactic body radiation therapy to stereotactic body radiation therapy alone to see how well they work in treating patients with pain from cancer that has spread to the bones (bone metastases). Bone is a common site of metastasis in advanced cancer, and bone metastases often result in debilitating cancer-related pain. The current standard of care to treat painful bone metastases is radiation therapy alone. However, many patients do not get adequate pain relief from radiation therapy alone. Another type of therapy that may be used to provide pain relief from bone metastases is cryoablation. Cryoablation is a procedure in which special needles are inserted into the tumor site. These needles grow ice balls at their tips to freeze and kill cancer cells. The goal of this trial is to compare how well cryoablation in combination with radiation therapy works to radiation therapy alone when given to cancer patients to provide pain relief from bone metastases.

Accuracy of 18F-rhPSMA-7.3 PET/ MRI for Prediction of Lymph Node Metastasis in Localized High-Risk Prostate Cancer

This clinical trial evaluates the use of an imaging scan (18F-rhPSMA-7.3 positron emission tomography \[PET\]/magnetic resonance imaging \[MRI\]) for identifying patients who are at risk of having their disease spread to the lymph nodes in those undergoing radical prostatectomy for prostate cancer that has not spread to other parts of the body (localized). Prostate specific membrane antigen (PSMA) PET/computed tomography (CT) has emerged as an option to stage newly diagnosed high risk prostate cancer patients. PSMA PET/CT has demonstrated improved diagnostic accuracy for identifying metastasis. PET is procedure in which a small amount of radioactive glucose (sugar) is injected into a vein, and a scanner is used to make detailed, computerized pictures of areas inside the body where the glucose is used. Because cancer cells often use more glucose than normal cells, the pictures can be used to find cancer cells in the body. MRI is procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body. These pictures can show the difference between normal and diseased tissue. This study may help researchers learn whether 18F-rhPSMA-7.3 PET/ MRI may improve predicting which patients are at risk of lymph node metastases and who are suitable candidates for pelvic lymph node dissection in patients with localized high-risk prostate cancer undergoing radical prostatectomy.

REVELUTION-2: Relugolix+Abiraterone Acetate (AA) Versus Leuprolide+AA Cardiac Trial

This phase III/IV trial compares the impact of leuprolide and abiraterone acetate (AA) versus relugolix and AA on the heart in hormone-naive patients with advanced prostate cancer receiving pelvic radiation therapy. Leuprolide is in a class of medications called gonadotropin-releasing hormone agonists (GNRHa). It prevents the body from making luteinizing hormone-releasing hormone (LHRH) and luteinizing hormone (LH). This causes the testicles to stop making testosterone (a male hormone) in men and may stop the growth of prostate tumor cells that need testosterone to grow. Abiraterone acetate, an androgen biosynthesis inhibitor, works by decreasing the amount of certain hormones in the body. Relugolix, a GNRH antagonist, works by decreasing the amount of testosterone produced by the body. This may slow or stop the spread of prostate tumor cells that need testosterone to grow. The use of hormone therapy with radiation therapy has been shown to improve survival, however, studies have suggested that the addition of hormone therapy may worsen heart (cardiac) disease and high blood pressure. In fact, studies have shown that the most common cause of death in prostate cancer patients is due to heart disease or heart attacks. Computed tomography (CT) scans create a series of detailed pictures of areas inside the body; the pictures are created by a computer linked to an x-ray machine. In this study, sophisticated cardiac CT images are used to take pictures of patients' heart and coronary arteries to help assess damage to the heart. Using cardiac CT and blood tests, this trial may help doctors determine which patients are at risk of cardiac disease when treated with combination hormone therapy, as well as the differential risk of leuprolide versus relugolix in combination with abiraterone acetate.

A Clinical Study Evaluating The Benefit of Adding Rucaparib to Enzalutamide for Men With Metastatic Prostate Cancer That Has Become Resistant To Testosterone-Deprivation Therapy

This randomized, placebo-controlled phase III trial is evaluating the benefit of rucaparib and enzalutamide combination therapy versus enzalutamide alone for the treatment of men with prostate cancer that has spread to other places in the body (metastatic) and has become resistant to testosterone-deprivation therapy (castration-resistant). Enzalutamide helps fight prostate cancer by blocking the use of testosterone by the tumor cells for growth. Poly adenosine diphosphate (ADP)-ribose polymerase (PARP) inhibitors, such as rucaparib, fight prostate cancer by prevent tumor cells from repairing their DNA. Giving enzalutamide and rucaparib may make patients live longer or prevent their cancer from growing or spreading for a longer time, or both. It may also help doctors learn if a mutation in any of the homologous recombination DNA repair genes is helpful to decide which treatment is best for the patient.
