Comparison of HDR vs. LDR Brachytherapy as Monotherapy for Intermediate Risk Prostate Cancer
Prostate CancerThis study will offer men with intermediate risk prostate cancer who are suitable for, and interested in, prostate brachytherapy, the opportunity to be randomized between low dose rate (LDR) brachytherapy using permanent implantation of radioactive seeds (the current standard of care in BC) and high dose rate (HDR) or temporary brachytherapy which is also available as a standard of care in BC but only when used as a boost in addition with external beam radiotherapy. In addition, men will be offered the opportunity for testing the aggressiveness of their cancer using Cell Cycle Progression Gene Profile.
Enzalutamide in Androgen Deprivation Therapy With Radiation Therapy for High Risk, Clinically Localised,...
Prostatic NeoplasmsThe purpose of this study is to determine the effectiveness of enzalutamide as part of adjuvant androgen deprivation therapy (ADT) with a luteinizing hormone releasing hormone analogue (LHRHA) in men having radiation therapy for localised prostate cancer at high risk of recurrence.
Phase I Trial of 225Ac-J591 in Patients With mCRPC
Prostate CancerThis is an open-label, single-center Phase I dose escalation study designed to determine the dose-limiting toxicity (DLT) and the maximum tolerated dose (MTD) of 225Ac-J591 in a single dose regimen.
Study Evaluating the Addition of Pembrolizumab to Radium-223 in mCRPC
Prostate CancerThis research study is studying the safety and tolerability of an investigational combination of drugs, radium-223 plus pembrolizumab as a possible treatment for castration-resistant prostate cancer. The interventions involved in this study are: Radium-223 Pembrolizumab
VMAT for Dominant Intraprostatic Lesion
Prostate CancerThe aim of this study was to determine the efficacy and safety of the implementation of a program of " image-guided focal Intensification dose to intraprostatic dominant lesion " in men with localized prostate cancer (PCa) of intermediate and high risk (criteria NCCN) eligible to receive radiotherapy in the Department of Radiation Oncology of HUP (Hospital Universitario de La Princesa), within the established dose escalation protocol with intensity modulated image-guided radiotherapy (IMRT / IGRT).
Olaparib in Men With High-Risk Biochemically-Recurrent Prostate Cancer Following Radical Prostatectomy,...
ProstateOlaparib has demonstrated preliminary efficacy in metastatic castration-resistant prostate cancer. In a trial of 49 evaluable patients treated with olaparib, 11 / 49 experienced a PSA response, and every patient with a radiographic response also had a PSA5 response. Ten of 11 responders had mutations in DNA repair genes. While PARP inhibition is showing promise in these initial studies, reserving its use for end-stage patients may not be the optimal timing for olaparib therapy in some patients. In addition, PARP enzymes function in roles beyond DNA repair, and specifically for prostate cancer are involved transcriptional regulation of the androgen receptor. PARP inhibition has not been tested in earlier disease states for prostate cancer.

Abiraterone With Discontinuation of Gonadotropin-Releasing Hormone Analogues in Metastatic Prostate...
Prostatic NeoplasmsThe goal of this study is to find out if patients with prostate cancer being treated with the medications abiraterone and prednisone can discontinue hormone injections (examples include leuprolide, goserelin, triptorelin and degarelix). Abiraterone and prednisone are pills used to treat patients with prostate cancer. When abiraterone and prednisone are used, hormone injections are usually continued to maintain a low testosterone level in the blood. This study is being done to find out if testosterone in the blood will stay low while abiraterone and prednisone are used without continued hormone injections.
FOcal Radiation for Oligometastatic Castration-rEsistant Prostate Cancer (FORCE)
Prostate CancerThis clinical trial will determine whether the addition of radiotherapy to standard of care systemic therapy improves objective progression-free survival compared to systemic therapy alone in patients with oligometastatic castration-resistant prostate cancer.
Prostate SBRT for Locally Recurrent Prostate Cancer After Prior Radiotherapy
Prostate CancerProsatatic NeoplasmBackground: Prostate cancer is the second leading cause of cancer death in U.S. men. Radiation is an effective treatment for most patients with localized prostate cancer, but sometimes the tumor returns. Researchers want to see if a highly focused type of radiation can help. It is given in only 5 treatments. It is called stereotactic body radiation therapy (SBRT). Objective: To study the maximum tolerated dose and side effects of stereotactic body radiation therapy in people with a local recurrence of prostate cancer after radiation. Eligibility: Men at least 18 years old who have recurrent prostate cancer after radiation therapy and no evidence of distant metastatic disease Design: Participants will be screened with blood tests, physical exam, and medical history. They may also have: Magnetic resonance imaging (MRI) scan of the prostate.. PET/CT scan. Participants will get an injection of 18F-DCFPyL for the PET scan. They will lie very still on their back on the scanner table. Small samples of prostate tumor tissue will be taken by a needle through the skin or rectum to see if the cancer is in the prostate. Small metal seeds will be placed into the prostate at the same time to help guide the radiation. About 2 weeks later, participants will have a radiation treatment planning CT scan. Participants will answer questions about their urine function, bowel function, erectile function, and mood. Participants will receive SBRT. They will have 5 radiation treatments over 2 weeks. Participants will have follow-up visits. They will have a physical exam, blood tests, and questionnaires. Six months after ending SBRT, the 18F-DCFPyL PET/CT will be repeated. Participantes will continue to have routine visits until two years after treatment is completed....
