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.

Testing the Effects of Low Dose Apalutamide on Prostate-Specific Antigen (PSA) Levels in Men Scheduled for Removal of the Prostate Gland

Apalutamide is an anti-androgen that blocks the effect of testosterone on prostate cancer growth. This phase IIa trial is designed to determine whether very low doses of apalutamide, given for 3 to 4 weeks before prostate surgery to men with prostate cancer confined to the prostate gland, reduces plasma levels of PSA (a biomarker of apalutamide's ability to block testosterone). If low dose apalutamide lowers PSA levels in this setting, further study of this agent in men with localized prostate cancer who wish to delay definitive therapy with surgery or radiation may be warranted.

Adaptive Radiation Therapy (ART) Stereotactic Ablative Body Radiotherapy (SABR) for Primary Localized Prostate Cancer

This clinical trial evaluates changes in quality of life after two treatments with near margin-less adaptive radiation therapy (ART) compared to five treatments with standard stereotactic ablative body radiotherapy (SABR) in patients with prostate cancer that has not spread to other parts of the body (localized). ART is a type of radiation therapy that uses information gathered during the treatment cycle to inform, guide, and alter future radiation treatments with respect to location and dose. It may be able to deliver radiation to the site of disease over a shorter time and with smaller margins (less treatment delivered to nearby healthy tissues). SABR 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. Shorter duration near margin-less ART may be just as effective at treating patients with localized prostate cancer but have less quality of life side effects than standard SABR.

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.

Image-Guidance and Online Adaptation With Stereotactic Body Radiation Therapy for the Treatment of Localized Prostate Cancer, MANTICORE Trial

This clinical trial studies the side effects of image-guidance and online adaptation with stereotactic body radiation therapy (SBRT) for the treatment of patients with prostate adenocarcinoma that has not spread to other parts of the body (localized). Image-guided SBRT is a standard treatment for localized prostate cancer. This treatment uses imaging of the cancer within the body to define and localize the area to be treated with the radiation. Imaging can be obtained using either computed tomography (CT), magnetic resonance imaging (MRI), or a combination of the two. Typically, with SBRT, a radiation plan is developed based on the CT or MRI images obtained before treatment begins and adjustments are not made to the plan during treatment. However, anatomy can be different from day-to-day which may cause radiation to be delivered to the normal surrounding structures and possibly more side effects. During image-guided SBRT with online adaptation, the initial radiation plan is designed similarly; however, when the patient presents for radiation, the attending radiation oncologist, a dosimetrist, and a medical physicist "re-optimize" the radiation plan using the current anatomy of the day, meaning the changes in bladder and prostate size/shape are taken into account. The initial plan and the re-optimized plan are then compared, and the plan that has the optimal balance between delivering a tumor killing dose of radiation and minimizing radiation dose to normal surrounding structures is delivered. Image-guidance and online adaptation with SBRT may lower side effects and be a safer way to treat localized prostate adenocarcinoma.

Vitamin D for Prostate Endocrine Therapy

This phase III trial tests whether high-dose vitamin D works in treating androgen-deprivation therapy (ADT)-induced bone loss in patients with prostate cancer who are undergoing androgen-deprivation therapy. Vitamins are substances that the body needs to grow and develop normally. Vitamin D helps the body absorb calcium. Calcium is one of the main building blocks of bone. A lack of vitamin D can lead to bone diseases such as osteoporosis or rickets. This trial may help researchers determine if high-dose vitamin D helps keep bones strong, lowers number of falls, and lessens fatigue in men getting androgen-deprivation therapy.

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.

Conventional or Hypofractionated Radiation Therapy in Treating Patients With Prostate Cancer

This phase III trial studies how well hypofractionated radiation therapy works compared to the conventional one in treating patients with prostate cancer. Radiation therapy uses high energy beams to kill tumor cells and shrink tumors. 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.

Computed Tomography-Guided Stereotactic Body Radiation Therapy With Intrafraction Motion Monitoring for the Treatment of Localized Prostate Cancer, ILLUSION Trial

This clinical trial studies the side effects of computed tomography (CT)-guided stereotactic body radiation therapy (SBRT) with intrafraction motion monitoring and to see how well it works in treating patients with prostate cancer that has not spread to other parts of the body (localized). In CT-guided SBRT, x-ray-based imaging and cone-beam CTs are used to define and localize the area to be treated with SBRT. 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. A recent randomized trial showed that while SBRT is associated with less urinary incontinence and erectile dysfunction than complete surgical removal of the prostate, there are more urinary irritative side effects and more bowel side effects than with surgery. One source of uncertainty in SBRT that may contribute to genitourinary (GU) and gastrointestinal (GI) side effects is the necessity of treating a "margin" of volume around the prostate to account for its movement during SBRT. Intrafraction motion monitoring is any technique or system designed to track the movement of the body and target during fractions of external beam radiation to keep the beam on target. This allows for the patient to be repositioned, if needed, to ensure delivery of the SBRT to only the planned treatment area. CT-guided SBRT with intrafraction motion monitoring may lower GU and GI side effects by allowing tighter margins, as has been demonstrated with magnetic resonance imaging (MRI)-guided SBRT.

Feasibility and Effect of Wrapping Nerves With a Multi-Layer Perinatal Tissue Allograft During Prostatectomy

This clinical trial studies whether a new multi-layer perinatal tissue allograft, MLG-Complete (Trademark), can be used to improve complications after nerve-sparing robot-assisted radical prostatectomy (RARP) in patients with prostate cancer that has not spread to other parts of the body (localized). Two major complications that can happen after complete surgical removal of the prostate (radical prostatectomy) include erectile dysfunction and urinary incontinence, both of which greatly affect a patient's quality of life and social well-being. The goal of nerve-sparing radical prostatectomy is to preserve erectile and urinary function, but damage to the surrounding nerves and blood vessels can still occur causing the patient to experience the complications. An allograft is the transplant of an organ, tissue, or cells from one individual to another individual of the same species who is not an identical twin. The MLG-Complete allograft is made up of perinatal tissue and is placed on the nerve bundles during a nerve-sparing RARP. It is meant to serve as a barrier and provide coverage to the nerve bundles from the surrounding environment, which may improve post-nerve-sparing RARP complications.

Comparison of High-Dose Rate Brachytherapy and Stereotactic Ablative Radiotherapy as Monotherapy for the Treatment of Localized Prostate Cancer

This phase II trial compares high-dose rate brachytherapy and stereotactic ablative radiotherapy as monotherapy in treating patients with prostate cancer that has not spread to other parts of the body (localized). High-dose rate brachytherapy delivers radiation directly into the prostate within a few minutes by a single radioactive seed through temporarily placed plastic catheters inside the prostate gland. Stereotactic ablative radiotherapy is an external beam radiation method that delivers large doses of radiation to the cancer in a short period of time, usually 5 treatments. This trial aims to find which of these two approaches is better in terms of patient-reported quality of life.

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.

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.

rhPSMA-73 PET-MRI Imaging for the Detection of Prostate Cancer Among Men Who Are Otherwise Candidates for Active Surveillance

This clinical trial evaluates whether positron emission tomography-magnetic resonance imaging (PET-MRI) using the radioactive drug radiohybrid prostate-specific membrane antigen (rhPSMA)-7.3 may help in detecting higher grade or stage disease in men with low and favorable intermediate risk prostate cancer who are candidates for active surveillance. A PET scan is a test that uses a radioactive drug and a computer to create images of how organs and tissues in the body are functioning. The radioactive drug used in this study, rhPSMA-7.3, attaches to the abnormal cells in the body at a different rate than normal cells which allows the scanner to create a detailed picture of how the body is working. An MRI scan uses strong magnets and computers to create detailed images of the soft tissue in your body. A multiparametric (mp)MRI is a type of MRI scan that creates a more detailed picture of the prostate gland. Using rhPSMA-73 with PET-MRI and mpMRI may be more effective in detecting higher grade or stage disease in men with low and favorable intermediate risk prostate cancer.
