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.

CT- Versus MRI-Based Planning for High-Dose-Rate Prostate Brachytherapy for Prostate Cancer

This clinical trial studies the safety of a computed tomography (CT) scan, with or without a magnetic resonance imaging (MRI) scan, in planning for high-dose-rate (HDR) prostate brachytherapy treatment in patients with prostate cancer. Brachytherapy is a type of radiation therapy in which radioactive implants, such as pellets, seeds, ribbons, wires, needles, balloons, or capsules, are placed in the body, directly into or near the tumor. The radiation is delivered through a flexible tube called a catheter or a larger device called an applicator. Treatment planning, or simulation, is a process used to plan radiation therapy so that the target area is precisely located and marked. A CT scan is a procedure that uses a computer linked to an x-ray machine to make a series of detailed pictures of areas inside the body. The pictures are taken from different angles and are used to create 3-dimensional views of tissues and organs. An MRI is a procedure in which radio waves and a powerful magnet linked to a computer are used to create detailed pictures of areas inside the body. The addition of MRI to CT for HDR prostate brachytherapy treatment planning may help patients have less urine leakage and less pain after treatment.

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.

Testing the Effects of Exercise on Colorectal Cancer Development After Treatment With Pelvic Radiation Therapy for Prostate Cancer

This clinical trial evaluates the effects of exercise therapy on signs of colorectal cancer in colon tissue and blood in people who completed pelvic radiation therapy for prostate cancer. People who get radiation in the pelvic area have a higher chance of developing colon cancer years later. This is because radiation can cause new mutations and inflammation. Research shows that exercise lowers colon cancer risk by about 30%. The results of this trial may help researchers better understand how exercise affects the development of colorectal cancer in patients who were treated with pelvic radiation therapy for prostate cancer.

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.

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.

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.

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.

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.

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.

Robot-Assisted Radical Prostatectomy With or Without Vesicopexy in Patients With Prostate Cancer

This phase III trial compares the effects of robot-assisted radical prostatectomy (RARP) with or without vesicopexy on urinary continence (a person's ability to control their bladder) and quality of life in patients with cancer of the prostate. RARP is the most adopted surgical approach for treatment of prostate cancer that has not spread to other places in the body (non-metastatic). Urinary incontinence (inability to control the bladder) is one of the most common complications of RARP, impacting patients' quality of life and psychological well-being. Different techniques have been proposed to improve urinary continence following RARP. Vesicopexy is one technique that restores the bladder to its normal position in the body after RARP. This study aims to evaluate whether RARP with vesicopexy may improve urinary continence and quality of life after surgery in prostate cancer patients.

Testosterone Replacement Therapy for the Treatment of Low Testosterone in Hypogonadal Men With Localized Prostate Cancer on Active Surveillance

This phase IV trial studies the effects of testosterone replacement therapy (TRT) on treatment outcomes in hypogonadal men with prostate cancer that has not spread to other parts of the body (localized) and who are on active surveillance (AS). AS in prostate cancer involves closely watching the patient's condition through regular physical exams and blood tests, but not giving treatment unless there are changes in test results. It can be a practical alternative to treatment in localized prostate cancer. Hypogonadal men have low testosterone associated with symptoms such as low libido and erectile problems. TRT can be used to treat hypogonadism by increasing testosterone levels, which may improve associated symptoms. TRT is often not used in men with prostate cancer due to concerns it may lead to the cancer growing or spreading. This may lead hypogonadal men to have a poor quality of life or to discontinue AS. TRT may improve treatment and quality of life outcomes in hypogonadal men with localized prostate cancer on active surveillance.

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.

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.
