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.

The purpose of this study is to see how well PROSTVAC -V/F works in stopping prostate cancer from coming back or relapsing. This study will also look at the safety of PROSTVAC-V/F.

Single center, single-arm, open-label, 60-month follow-up phase IIb clinical trial. Men with localized prostate cancer will receive TOOKAD® Soluble VTP under general anesthesia. To evaluate the absence of biopsy detectable Gleason grade 4 or 5 prostate cancer tumors anywhere in the prostate gland on 12-month, post-treatment biopsy following TOOKAD® Soluble-VTP in men with prostate cancer Gleason score 7(3+4).

Background: Some people with prostate cancer have a rise in prostate-specific antigen (PSA). This can happen even after treatments like radiation and surgery. Androgen deprivation therapy (ADT) drugs and close monitoring are one standard way to treat this group of people. Another way is to monitor people and their PSA values over time. Researchers want to see if a combination of new drugs can help these people. Objective: To see if the combination treatment of PROSTVAC, CV301, and MSB0011359C (M7824) can induce an anti-tumor attack in people with biochemically recurrent prostate cancer. Eligibility: People ages 18 and older with certain kinds of prostate cancer Design: Participants will be screened with Medical history Physical exam Blood and urine tests A scan of the neck, chest, abdomen, and pelvis A bone scan A sample of tissue that was already taken will be tested. This will confirm the diagnosis, stage, and disease status. Some participants will have close monitoring with four monthly PSA checks. All participants will get two study drugs as shots under the skin. They will get the third drug in a vein. They will get the drugs over at least 7 months. Their vital signs will be checked before they get the drugs and for up to 1 hour after. Participants will have frequent study visits. They will have physical exams, urine and blood tests, and scans. Participants will return to the clinic about 4 weeks after they stop taking the study drugs. They will have a medical history, physical exam, and blood tests. They may also have long-term follow-up visits.

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 purpose of this study is to assess enzalutamide plus leuprolide in patients with high-risk nonmetastatic prostate cancer progressing after radical prostatectomy or radiotherapy or both. The randomized / blinded portion of the study is now completed following primary endpoint analyses. The study remains ongoing in open label format.

Determine the effect of enzalutamide and dutasteride or finasteride on the time to prostatic-specific antigen level increase in patients age 65 or older.

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.

This phase II trial studies how well apalutamide works in treating patients with prostate cancer before radical prostatectomy. Androgen can cause the growth of prostate cancer cells. Hormone therapy using apalutamide may fight prostate cancer by lowering the amount of androgen the body makes and may make it less likely for patients to receive radiation therapy after surgery.
