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.

A Study To Evaluate Hypofractionated Proton Therapy Or IMRT For Recurrent, Oligometastatic Prostate Cancer

This phase II trial studies the side effects of radiation therapy (hypofractionated proton beam therapy or IMRT) for the treatment of prostate cancer that has come back (recurrent) or that has spread to a limited number of sites (oligometastatic) following primary localized treatment. Hypofractionated proton beam radiation therapy delivers smaller doses of radiation therapy over time and may kill more tumor cells and have fewer side effects. IMRT uses high energy x-rays to kill tumor cells and shrink tumors. This trial is being done to find out if a shorter course of radiation therapy is better with fewer side effects for patients with recurrent prostate cancer.

Nivolumab + Docetaxel + ADT in mHSPC Patients With DDRD or Inflamed Tumors

This research study is studying a combination of hormonal therapy, chemotherapy, and immunotherapy as a possible treatment for metastatic hormone-sensitive prostate cancer. The names of the study drugs involved in this study are: * Androgen deprivation therapy (ADT) with a drug of your physician's choice. This may include leuprolide (Lupron), goserelin acetate (Zoladex), or degarelix (Firmagon). * Docetaxel * Nivolumab

Hypofractionated Radiation Therapy for Treating Prostate Cancer High-Risk Features Following Radical Prostatectomy

This phase II trial studies how well hypofractionated radiation therapy works in treating participants with prostate cancer high-risk features following radical prostatectomy. 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.

177-Lutetium-PSMA Before Stereotactic Body Radiotherapy for the Treatment of Oligorecurrent Prostate Cancer, The LUNAR Study

This phase II trial tests whether 177-Lutetium-PSMA given before stereotactic body radiotherapy (SBRT) works to improve cancer control rate in patients with 1-5 prostate cancer tumors that have come back after prior treatment (oligorecurrent). Radioactive drugs, such as 177-Lutetium-PSMA, may carry radiation directly to tumor cells and not harm normal cells. SBRT 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. Giving 177-Lutetium-PSMA before SBRT may make the SBRT more effective.

Focal Therapy With Stereotactic Body Radiation Therapy (SBRT) for Patients With a Single Prostate Tumor

Background: The current standard treatment of prostate cancer is either surgery or radiation. Typically, this includes either the removal or radiation of the whole prostate gland. Many people now seek out focal therapy options to decrease the side effects of treatment. Until now, several forms of physical destruction with heat (thermal ablation), cold (cryotherapy), sound waves (HIFU), laser (FLA), and electrical energy (IRE). A new type of radiation (SBRT) may be an effective way to cure men of early-stage prostate cancer with fewer side effects than standard treatments. Objective: To see how people with untreated localized prostate cancer will respond to focal therapy with SBRT. Eligibility: People aged 18 years and older with untreated localized prostate cancer (prostate cancer which has not spread outside of the prostate gland). Design: * Participants will undergo screening including blood tests, an MRI, a PSMA PET/CT (18F-DCFPyL), and a biopsy. * Small, non-radioactive, gold seeds about the size of a grain of rice will be placed in and/or around the tumor to help target the radiation treatment. * Radiation (SBRT) will occur in 2 separate sessions about 1 week apart. No sedation is used, these sessions are painless. Each session will take about 1-2 hours. Participants can go home afterwards. * Follow-up will continue for 2 years with repeat scans (MRI and PSMA PET/CT) and blood (PSA) tests. * After two years, a biopsy will be done to understand the impact of this new treatment on prostate cancer.

Focal Radiation Therapy (HDR-Brachytherapy) for the Treatment of Prostate Cancer

This clinical trial tests the effect of focal radiation therapy, high dose rate-brachytherapy (HDR-BT), in treating patients with prostate cancer. Prostate cancer is the most diagnosed cancer in men and there are many treatments available, including surgery and radiation therapy. Although surgery and radiation therapy improve survival urinary and sexual function can be significantly affected and can be long lasting. HDR-BT, a type of focal radiation therapy also known as internal radiation therapy, uses radioactive material placed directly into or near a tumor to kill tumor cells. Giving HDR-BT may be effective in providing local control while reducing side effects in patients with prostate cancer.

Hemi-Gland Cryoablation for Prostate Cancer at UCLA

This is a prospective data collection of men who are electing to undergo prostate hemi-gland cryoablation. The purpose of this observational research study is to investigate the localized treatment of prostate cancer using hemi-gland cryoablation. UCLA patients undergoing hemi-gland cryoablation are a unique cohort compared to prior research because all patients at UCLA have had a pre-treatment multi-parametric MRI and Ultrasound fusion targeted biopsy; they will be followed in a similar fashion. This results in more precise assessment of a target region of cancer for ablation which may, in turn, result in improved clinical outcomes.

High-Risk prostatE Cancer radiatiOn Versus surgERy

Prospective cohort study comparing robot-assisted radical prostatectomy and external beam radiotherapy +/- androgen deprivation therapy for high-risk non-metastatic prostate cancer in terms of health-related quality of life, functional outcomes, cost-effectiveness, progression-free survival and distant metastasis-free survival.

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.

Hypofractionated Radiation Therapy or Conventional Radiation Therapy After Surgery in Treating Patients With Prostate Cancer

This randomized phase III trial studies how well hypofractionated radiation therapy works compared to conventional radiation therapy after surgery in treating patients with prostate cancer. 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. Conventional radiation therapy uses high energy x-rays, gamma rays, neutrons, protons, or other sources to kill tumor cells and shrink tumors. It is not yet known whether giving hypofractionated radiation therapy or conventional radiation therapy after surgery may work better in treating patients with prostate cancer.

A Study on the Effects of Exercise Therapy on Signs of Prostate Cancer

To determine the effects of exercise therapy on molecular, radiologic, and pathologic nimbosus hallmarks versus usual care control in men on Active Surveillance for localized prostate cancer.

Hyperpolarized Pyruvate (13C) MR Imaging in Monitoring Patients With Prostate Cancer on Active Surveillance

This phase II trial studies the side how well hyperpolarized carbon C 13 pyruvate (HP C-13 pyruvate) magnetic resonance imaging (MRI) works in monitoring patients with prostate cancer on active surveillance who have not received treatment. Diagnostic procedures, such as MRI, may help visualize HP C-13 pyruvate uptake and breakdown in tumor cells.

Treating Prostate Cancer That Has Come Back After Surgery With Apalutamide and Targeted Radiation Based on PET Imaging

This phase III trial tests two questions by two separate comparisons of therapies. The first question is whether enhanced therapy (apalutamide in combination with abiraterone + prednisone) added to standard of care (prostate radiation therapy and short term androgen deprivation) is more effective compared to standard of care alone in patients with prostate cancer who experience biochemical recurrence (a rise in the blood level of prostate specific antigen \[PSA\] after surgical removal of the prostate cancer). A second question tests treatment in patients with biochemical recurrence who show prostate cancer spreading outside the pelvis (metastasis) by positron emission tomography (PET) imaging. In these patients, the benefit of adding metastasis-directed radiation to enhanced therapy (apalutamide in combination with abiraterone + prednisone) is tested. Diagnostic procedures, such as PET, may help doctors look for cancer that has spread to the pelvis. Androgens are hormones that may cause the growth of prostate cancer cells. Apalutamide may help fight prostate cancer by blocking the use of androgens by the tumor cells. Metastasis-directed targeted radiation therapy uses high energy rays to kill tumor cells and shrink tumors that have spread. This trial may help doctors determine if using PET results to deliver more tailored treatment (i.e., adding apalutamide, with or without targeted radiation therapy, to standard of care treatment) works better than standard of care treatment alone in patients with biochemical recurrence of prostate cancer.

Whole Versus Partial Gland Boost During Prostate SBRT

This phase 2/3 randomized trial evaluates whether dose escalation to the dominant intra-prostatic lesion (DIL) compared to whole gland dose escalation during prostate stereotactic body radiotherapy (SBRT) results in differences in genitourinary (GU) and gastrointestinal (GI) toxicities.

Placebo-Controlled Trial of Urolithin A Supplementation in Men With Prostate Cancer Undergoing Radical Prostatectomy, URO-PRO Trial

This phase II randomized control trial assesses the effect of Urolithin A (Uro-A) supplementation compared to placebo in men with biopsy-confirmed prostate cancer undergoing radical prostatectomy (RP) progressive disease. A total of 90 men will be accrued and randomized 1:1 to receive a 1000 mg daily dose of Uro-A in two 250 mg capsules PO BID or two placebo capsules BID daily for 3 to 6 weeks prior to RP. The primary endpoint is to determine the effect of Uro-A on decreasing prostate tumor tissue oxidative stress (measured by 8-OHdG) compared to placebo.

Hypofractionated Accelerated Pelvic Nodal Radiotherapy (GCC 2048)

A phase I trial to determine the safety of delivering three sequentially shorter RT schedules (20, 16, and 12 fractions) of HypoFx pelvic nodal RT in combination with a HypoFx, simultaneous integrated boost (SIB) to the prostate that have been designed to incrementally increased the biological equivalent dose (BED) to prostate cancer, while maintaining a constant BED to normal tissue toxicity.

CT-guided Stereotactic Body Radiation Therapy and MRI-guided Stereotactic Body Radiation Therapy for Prostate Cancer, MIRAGE Study

This phase III trial studies compares CT-guided stereotactic body radiation therapy and MRI-guided stereotactic body radiation therapy (SBRT) in treating prostate cancer. Image-guided SBRT is a standard treatment for prostate cancer, which combines imaging of the cancer within the body with the delivery of therapeutic radiation doses produced on a linear accelerator machine. Imaging modalities for image-guided SBRT can be either computed tomography imaging (CT), magnetic resonance imaging (MRI), or a combination of the two. This research is being done to help determine whether there are benefits to MRI-guidance over CT-guidance in patients who are receiving the same radiation dose by SBRT to treat prostate cancer.

Single-Port Transvesical Partial Prostatectomy Versus High Intensity Focused Ultrasound

This study aims to compare the novel single-port robotic partial prostatectomy to High-intensity focused ultrasound (HIFU) in patients with low to intermediate risk localized prostate cancer. These interventions have become acceptable focal therapies prevalent with beneficial oncologic outcomes and therefore need to be examined further.

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.

Nutrition and Exercise Interventions for Androgen Deprivation Therapy-Induced Obese Frailty in Elderly and Non-Elderly Survivors of Advanced Prostate Cancer

This trial studies how well nutrition and exercise interventions work in reducing androgen deprivation therapy-induced obese frailty in prostate cancer survivors. Individualized nutrition and exercise advice for prostate cancer patients on androgen deprivation therapy may help to reduce obese frailty and change the levels of myokines in blood.

Testing Shorter Duration Radiation Therapy Versus the Usual Radiation Therapy in Patients With High Risk Prostate Cancer

This phase III trial compares stereotactic body radiation therapy (SBRT), (five treatments over two weeks using a higher dose per treatment) to usual radiation therapy (20 to 45 treatments over 4 to 9 weeks) for the treatment of high-risk prostate cancer. SBRT 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 of time. This trial is evaluating if shorter duration radiation prevents cancer from coming back as well as the usual radiation treatment.

Utilization of Flotufolastat 18F PET for Post-Focal Therapy Prostate Cancer Evaluation

This is a phase II single arm, open-label clinical trial determining diagnostic accuracy of Flotufolastat F18 PET in subjects with prostate adenocarcinoma. These are subjects who have not previously received treatment for prostate cancer.

Intermittent Fasting Using a Fasting-Mimicking Diet to Improve Prostate Cancer Control and Metabolic Outcomes

This is a Phase 2, randomized two-armed, multi-site study of 138 patients with metastatic castrate sensitive prostate adenocarcinoma. Patients will be randomized 1:1 to receive the fasting mimicking diet, or usual diet. All patients will receive standard of care treatment for their prostate cancer. The fasting mimicking diet will be consumed for 5 days per month for a total of 6 months and will be monitored by trained research dietitians. This study aims to examine the effects of a fasting mimicking diet (5 days per month eating L-Nutra products only for 6 months) vs. usual diet on response to cancer treatment of metastatic castrate sensitive prostate adenocarcinoma.
