Active clinical trials for "Prostatic Neoplasms"

The purpose of this study is to establish the maximum tolerable dose of niraparib when combined with prostate stereotactic body radiotherapy (SBRT), abiraterone, leuprolide, and prednisone (the phase 1 portion of the study) and determine 3-year biochemical PSA recurrence free-survival with this treatment approach (the phase 2 portion of the study).

The objective of this study is to see if providing an appropriate therapy based on the genomic testing of prostate tumour tissue will result in an improved clinical response. Each participant will be treated with 8 weeks of a luteinizing hormone-releasing hormone agonist (LHRHa) plus apalutamide (APA) while genome sequence characterization is being done. Participants with biopsy specimens deemed unevaluable for genomic testing will remain on LHRHa plus APA for an additional 16 weeks. Participants with evaluable tissue will be assigned to one of the open-label sub-studies on the basis of genomic profiling results. Within each group, they will be randomized to a specific treatment arm either LHRHa plus APA alone or adding abiraterone acetate and prednisone, docetaxel or niraparib. The study will evaluate the response rate and outcomes after radical prostatectomy in each arm of the trial.

A phase IIR cmRCT trial companion to PERa registry, investigating the merit of SABR consolidation in men with metastatic prostate cancer. 80 patients will be randomly selected to be offered experimental SABR based on PSMA-PET detected disease after maximal systemic response. The primary endpoint is the rate of FFS at 1 year. Patients will be stratified according to hormone sensitive vs resistant disease prior to randomisation.

The main purpose of study is to evaluate hypofractionated stereotactic radiotherapy (SBRT) using CyberKnife for Patients with low and intermediate risk of progression prostate cancer.

The purpose of this study is to determine the feasibility and effects of an adapted Exercising Together, a partnered resistance training program, on the physical and mental health of prostate cancer survivors and their informal caregiver. The Exercising Together program is designed to promote teamwork during supervised group exercise classes delivered remotely through videoconferencing software. The intervention period will be 3-months with a 3-month follow-up.

The purpose of this study is to determine the pharmacokinetics, dosimetry, tolerance, tumor detection rate of 68Ga-PSMA-33 in patient with Prostate Cancer (PCa).

Prostate cancer is the second leading cause of cancer death in men. According to estimates by the American Cancer Society Prostate for 2022, about 268,490 men would be diagnosed with prostate cancer and 34,500 would die from the disease. Clinical evolution follows the clinical stages are: localized disease, biochemical recurrence after surgery or radiotherapy, and castration-sensitive or castration-resistant metastatic disease. Localized disease is often classified according to a risk stratification system, which includes assessment of the Gleason score, prostate-specific antigen (PSA) at diagnosis, number of involved fragments per disease at biopsy, and clinical T-staging. Gleason score greater than or equal to 8, PSA greater than or equal to 20 ng/dL at diagnosis, and/or involvement of the prostatic capsule or seminal vesicle are high-risk criteria for biochemical recurrence and later development of metastases, for which the standard treatment is radical prostatectomy or radiotherapy plus androgen deprivation therapy. Prostate-specific membrane antigen (PSMA) is highly expressed on the surface of prostate cancer cells, with relatively low expression in normal tissue. PSMA has been explored as a target in imaging studies using positron emission tomography (PSMA-PET) to reveal occult metastatic disease, as well as a target in the development of PSMA-based treatments with radioligands. According to Hoffman et al., performing PSMA-PET demonstrated greater sensitivity (85% vs. 38%) and specificity (98% vs. 91%), and determined more changes in patient management (28% vs. 15% ) compared to conventional images. Other studies have also demonstrated the greater accuracy of PSMA-based radiotracers compared to conventional images. Finding strategies that increase PSMA expression is a necessity for patients with prostate cancer. According to researchers, high SUVmax values are associated with better outcomes in patients treated with 177-lutetium-PSMA-617. PSMA expression can be rapidly modulated by androgen suppression. The investigators understand that there is great potential to evaluate darolutamide as a PSMA expression enhancer. However, to date there are no prospective data evaluating the effect of ARSI in increasing PSMA expression in localized disease. Here the investigators propose a phase 2 study to investigate the efficacy of a limited course of darolutamide as a PSMA expression enhancer in men with localized prostate cancer according to conventional imaging. PSMA-PET/CT scans will be acquired before and after treatment with darolutamide, as detailed in the protocol. Slides of prostate biopsies and prostatectomies stained with hematoxylin and eosin (H&E) will be reviewed by two pathologists to select the most representative tumor block. Immunohistochemical (IHC) reaction using standard protocols will be performed using an anti-PSMA antibody and intraprostatic anti-androgens. Gene expression analysis will be performed using RNA extracted from biopsies and prostatectomies and evaluated by a panel of over 300 transcripts. For methylation patterns, hematoxylin and eosin (H&E) slides from prostate biopsies and prostatectomies will undergo DNA extraction and evaluation of the methylation profile performed using a kit. It is expected to identify that treatment with darolutamide increases PSMA expression and that the biochemical mechanisms involved can be better evidenced.

This is prospective single-arm case-control study designed to compare in parallel PSMA PET/TRUS (trans-rectal or trans-perineal) fusion biopsy ("experimental test") with mpMRI/TRUS fusion prostate biopsy ("standard test") in men with a high suspicion of PCa after at least one negative biopsy.

The purpose of this research is to test intervention strategies that encourage and support Black or African American men who are 40 and older to complete prostate cancer screening, and specifically to complete a prostate-specific antigen (PSA) test.

Background: People with prostate cancer usually have their cancer imaged with a CT scan and bone scan. They then have their prostate gland removed. Researchers want to test a scan that might predict if prostate cancer will return after this surgery. Objective: To test if a PET/CT scan before the prostate gland is removed can predict if prostate cancer will return. Also, to test if this approach is better or worse than the usual approach for prostate cancer. Eligibility: Men ages 18 and older with prostate cancer that appears to be contained within the prostate but is at risk of having spread Design: Participants will be screened with: Medical history Blood tests CT and MRI scans: Participants will lie in a machine. The machine will take pictures of the body. Bone scan Participants will have a radiotracer injected into a vein. They will have a PET/CT scan of their whole body 60 90 minutes later. During the scan, they will lie on their back and stay still. Within 60 days after the scan, participants will have surgery. This will remove the prostate gland and lymph nodes around it. Some tissue will be used for genetic testing. If the PET/CT scan suggests the cancer has spread, participants may need to have another biopsy within 60 days after the scan. After surgery, participants will have follow-up visits for 5 years. They will have 5 visits the first year and 2 the second. Then they will have visits once a year. If participants cancer returns, they will have repeat PET/CT scans.
