Active clinical trials for "Prostatic Neoplasms"

Background: Prostate cancer is the second leading cause of cancer deaths in American men. Few options exist to create images of this type of cancer. Researchers think an experimental radiotracer called 18F-DCFPyL could find sites of cancer in the body. Objective: To see if 18F-DCFPyL can identify sites of prostate cancer in people with the disease. Eligibility: People ages 18 and older who have metastatic prostate cancer Design: Participants will be screened with: Blood tests Physical exam Medical history Participants will be assigned to 1 of 2 groups based on their PSA. Participants will have 18F-DCFPyL injected into a vein. About 2 hours later they will have a whole-body Positron Emission Tomography/Computed Tomography (PET/CT). For the scan, they will lie on their back on the scanner table while it takes pictures of the body. This lasts about 50 minutes. On another day, participants will have 18F -NaF injected into a vein. About 1 hour later, they will have a whole-body PET/CT. Participants will be contacted 1 3 days later for follow-up. They may undergo PET/Magnetic Resonance Imaging (MRI) either after having a 18F-DCFPyL PET/CT, or in place of PET/CT imaging. A tube may be placed in the rectum. More coils may be wrapped around the outside of the pelvis. If the 18F-DCFPyL PET/CT is positive participants will be encouraged to undergo a biopsy of one of the tumors. The biopsy will be taken through a needle put through the skin into the tumor. Participants will be followed for 1 year. During this time researchers will collect information about their prostate cancer, such as PSA levels and biopsy results. About 4-6 months after scanning is completed, participants may have a tumor biopsy. The biopsy will be taken through a needle put through the skin into the tumor. ...

The purpose of the study is to find out the feasibility and effects of ultra-hypofractionated radiotherapy to the prostate and dominant lesion as definitive treatment for intermediate risk prostrate cancer.

Patients will take 150 mg of GSE product by mouth twice daily and will be evaluated every 6 weeks for 3 months, then every 3 months thereafter for up to one year.

The study is to examine a moderate hypofractionation regimen of proton beam therapy for high risk or unfavorable intermediate risk prostate cancer. The prostate and seminal vesicles are treated with 6750 centigray (RBE) in 25 fractions (i.e. 270 centigray/fraction), while the regional pelvic nodes receive 4500 centigray (RBE) in 25 fractions (i.e. 180 centigray/fraction) simultaneously. The overall treatment time is 5 weeks.

The objectives of this study are to replicate the safety and efficacy of 68Ga-PSMA PET/CT and as a diagnostic and decision making tool in the management prostate cancer patients.The primary endpoints of the study are the incidence of adverse events (AE) in the study population up to 7 days following the scan, and the sensitivity and specificity of 68Ga-PSMA PET/CT vs CT on a per-patient and per-lesion basis.

This phase I trial studies the side effects and best dose of metformin hydrochloride when given together with enzalutamide in treating patients with prostate cancer that has not responded to previous treatment with hormones. Hormone therapy using enzalutamide may fight prostate cancer by lowering the amount of androgens the body makes and blocking the use of androgens by the tumor cells. Metformin hydrochloride, used for diabetes, may also help kill tumor cells. Giving enzalutamide together with metformin hydrochloride may kill more tumor cells.

The main purpose of this study is to determine if Magnetic Resonance Imaging (MRI), along with MRI targeted biopsy of suspicious lesions, is of value in detecting patients who would be likely to require treatment earlier.

The purpose of this study is to evaluate the effectiveness of niraparib in combination with abiraterone acetate plus prednisone (AAP) compared to AAP and placebo.

MAGIC-8 is a two-arm, multicenter, phase 1b/2 study to assess the efficacy of immunotherapy with either Nivolumab (anti-PD-1) or Nivolumab plus BMS-986253 combined with ADT using Degarelix (LHRH antagonist) for men with hormone-sensitive prostate cancer and a rising prostate-specific antigen (PSA). The purpose of this study is to see whether immunotherapy with either Nivolumab alone or Nivolumab plus BMS-986253 combined with Degarelix, which suppresses testosterone, is safe and can decrease the chance that the cancer will come back. The primary objectives are to 1) determine the rate of PSA recurrence defined as a PSA >0.2ng/ml for radical prostatectomy patients or PSA >2.0ng/ml for patients who received primary radiation therapy at a time point of 10 months after start of therapy; and 2) determine the safety and tolerability of either nivolumab or nivolumab plus BMS-986253 in combination with degarelix in men with hormone-sensitive prostate cancer. The secondary objectives include determining relapse-free survival (RFS) and % change in PSA to immunotherapy alone.

This is a global, multi-center, open-label, randomized phase 1b/2, active-controlled safety and efficacy study of oral administration of tazemetostat in combination with enzalutamide or abiraterone/prednisone (phase 1b) versus enzalutamide or abiraterone/prednisone alone in asymptomatic or mildly symptomatic subjects with progressive, metastatic castration-resistant prostate cancer (mCRPC) who have progressed on either abiraterone acetate, enzalutamide, or apalutamide or who are second generation anti-androgen treatment naive, and who have not received chemotherapy for mCRPC. This study is designed to determine the recommended phase 2 doses (RP2D) of tazemetostat in combination with either enzalutamide or abiraterone/prednisone, based on safety, tolerability, pharmacokinetic, pharmacodynamic, and efficacy profiles.
