Active clinical trials for "Prostatic Neoplasms"

This is an open-labeled, single-arm, interventional pilot study. It is being done to determine the feasibility of the administration of transdermal testosterone alternating with enzalutamide, as well as the safety and efficacy.

Stereo-Re-Pro aims to provide further evidence of Stereotactic Body Radiotherapy (SBRT) as a supplementary non-invasive curative treatment for local recurrence following radiotherapy. The objective of the first part of the trial (Phase I) is to select the recommended dose for salvage SBRT (either 5 x 6 Gy, 6 x 6 Gy, or 5 x 5 Gy) based on dose-limiting toxicity observed during the 18 weeks following the initiation of salvage-SBRT. Particular attention will be paid to the quality of life and tolerance of the treatment. The objective of the second part of the trial (phase II) is to estimate the efficacy of the salvage-SBRT in terms of biochemical relapse-free survival rate.

Background: Sometimes prostate cancer comes back after a person s prostate is removed. In this case, radiation is a common treatment. Radiation kills prostate cancer cells. It can be very effective. It is usually given in short doses almost every day for 6 or 7 weeks. Researchers want to see if a shorter schedule can be as effective. They want to see if that causes the same or fewer side effects. Usually, radiation is used to treat the entire area where the prostate was before surgery. In some patients, an area of tumor can be seen on scans. Researchers are also trying to see if they can give less dose to the area usually treated with radiation if the full dose is given to the tumor seen on scans. Objective: To find the shortest radiation schedule that people can tolerate without strong side effects. Eligibility: People at least 18 years old who have had a prostatectomy and will get radiation Design: Participants will be screened with: Medical history Physical exam Blood and urine tests Scan that uses a small amount of radiation to make a picture of the body Scan that uses a magnetic field to make an image of the body Participants will provide documents that confirm their diagnosis. Participants may have a scan of the abdomen and pelvis. Before they start treatment, participants will have another physical exam and blood tests. Participants will get radiation each day Monday through Friday. Treatment may last 2, 3, or 4 weeks. Participants may provide a tissue sample from a previous procedure for research. Participants will answer questions about their general well-being and function. About 4-5 weeks after they finish radiation treatment, participants will have a follow-up visit. They will be examined and give a blood sample. They will have 6 follow-up visits for the next 2 years.

The purpose of this first-in-man study is to evaluate safety and tolerability of ODM-208 in patients with metastatic castration-resistant prostate cancer.

This study aims to compare the treatment results of HIFU and Radical prostatectomy.

Phase 1/2 dose escalation study to assess the safety and tolerability of ARV-110 in men with mCRPC who have progressed on prior approved systemic therapies for their castrate resistant disease (one of which must be enzalutamide or abiraterone).

A dose-response relationship for radiation in the management of prostate cancer is well established. Local recurrence of prostate cancer after external beam radiotherapy occurs in at least 40% of patients treated because of inability to deliver sufficient dose through external beam techniques. These patients respond well to re-irradiation using brachytherapy with about 50% of selected patients remaining free of recurrence 5 years after salvage. Advanced imaging using multiparametric Magnetic Resonance Imaging (mpMRI) allows identification of the site of recurrence, permitting partial prostate salvage brachytherapy. There is extensive literature on Low Dose Rate salvage brachytherapy but less on High Dose Rate.

The main objective of the phase I/II trial is to determine the safety and efficacy of a single fraction SBRT at a dose of 19 Gy in patients with localized prostate cancer.

This phase I/II trial studies the best dose and side effects of olaparib and how well it works with radium Ra 223 dichloride in treating patients with castration-resistant prostate cancer that has spread to the bone and other places in the body (metastatic). PARPs are proteins that help repair DNA mutations. PARP inhibitors, such as olaparib, can keep PARP from working, so tumor cells can't repair themselves, and they may stop growing. Radioactive drugs, such as radium Ra 223 dichloride, may carry radiation directly to tumor cells and not harm normal cells. Giving olaparib and radium Ra 223 dichloride may help treat patients with castration-resistant prostate cancer.

The purpose of this study is to test the safety, tolerability, and effectiveness of the investigational drug nivolumab (Opdivo™) in combination with high dose radiation. Investigators also want to see if these study drugs help to delay the progression of prostate cancer.
