Active clinical trials for "Prostatic Neoplasms"

1) investigate the feasibility, tolerance, and safety of dose escalation via MR-guided stereotactic body radiation therapy and simultaneous integrated boost to the dominant intraprostatic lesions (DILs), 2) to assess the feasibility of DIL visualization based on multi-parametric MRI (mpMRI), and 3) to characterize longitudinal changes in imaging characteristics and identify urinary biomarkers for treatment response prediction

A prospective, Phase 3, multi center, single-arm, imaging study investigating the safety and diagnostic performance of rhPSMA 7.3 (18F) Positron Emission Tomography (PET) ligand in men with suspected prostate cancer recurrence based on elevated Prostate-specific antigen (PSA) following prior therapy.

Patients suffering either from newly diagnosed very high risk locally advanced and/or oligometastatic prostate cancer (cohort A), metastatic castration-resistant prostate cancer (mCRPC, cohort B), newly diagnosed postate cancer with planned radical prostatectomy (cohort C) or primary bladder cancer with planned radical cystectomy (cohort D) as identified by a multidisciplinary team of specialists, will be included. PET imaging patterns using PSMA- and FDHT PET scans will be correlated with prostate-specific membrane antigen and androgen specific receptor expression patterns in prostate cancer and bladder cancer.

The purpose of this study is to access the safety of combining sodium selenite with abiraterone and to see what doses of sodium selenite can be safely combined with abiraterone in treating castration resistant prostate cancer.

This is a prospective, single-center, open-label pilot study of 68GA-PSMA-11 given at a single time prior to PET/CT imaging in men with localized high risk prostate cancer or biochemical recurrence. The imaging agent (68 Ga-PSMA 11 will be administered on an outpatient basis. It will be administered prior to the PET/CT imaging. The objective is to evaluate the distribution of 68GA-PSMA-11 in tissues and to determine if this alters the planned clinical management.

The purpose of this research study is to compare the effects of a lycopene supplement made from tomatoes to a placebo (a capsule with no active ingredients) in men who have abnormal cells in the prostate, but have not yet had cancer detected. This study will allow us to see if taking lycopene for six months leads to favorable changes in abnormal prostate tissue and in chemicals measured in the blood that go along with a higher risk of developing cancer.

Visual assessment of diagnostic PET/CT (positron emission tomography/computed tomography) images obtained after a single intravenous injection of BAY86-7548 in patients with cancer.

Background: - Sodium fluoride (NaF) is a common compound that is found in various foods and can be used to increase bone strength. When this compound is added to a small dose of radiation (F-18), it collects in the bones, with higher amounts in areas where the bone is rapidly changing, such as the site of a healing fracture or a tumor. By giving F-18 NaF before a combined positron emission tomography/ computed tomography (PET/CT) scan, researchers hope to be able to better measure the changes in the bone that may indicate that a certain type of cancer (such as prostate cancer) has spread to the bones. Objectives: To evaluate the effectiveness of F-18 NaF in imaging studies to measure bone tumors and their change over time and compare with clinical course, in individuals with prostate cancer. To determine the smallest amount of change in the bone tumors that F-18 NaF can accurately measure. Eligibility: - Men at least 18 years of age who have been diagnosed with prostate cancer and have had imaging studies to determine whether the cancer has spread to their bones. Both patients with and without known bone involvement will be enrolled. Design: Participants will be screened with a physical examination, medical history, and imaging studies, and will provide baseline blood samples to evaluate kidney function. For the study, participants will have two F-18 NaF PET/CT scans on separate days for baseline. These repeat scans will be used to determine the amount of change that is due to the imaging process alone (i.e. not due to the disease getting better or worse. Participants will receive a dose of F-18 NaF intravenously, and will have PET/CT scanning over the body (mid ear to upper thighs) over 1 hour, the body followed by a complete whole-body PET/CT scan at approximately 2 hours after F-18 NaF injection. Participants will be watched closely for side effects from the F-18 NaF until the scans are done, and will be asked to drink plenty of water to void the F-18 NaF from the body after the scans. As a followup study, participants will have two more F-18 NaF PET/CT scans, one 4 to 8 months after the first scans and then one 10 to 14 months after the first scans. Participants will provide additional blood samples before the followup scans.

The purpose of this study is to determine whether stereotactic body radiation therapy (SBRT) with simultaneous boost (higher radiation dose) to areas within the prostate with more prominent cancerous growth (intraprostatic lesions) utilizing intensity modulated radiotherapy (IMRT) planning techniques is a safe and effective treatment in patients with low- and intermediate-risk localized prostate cancer.

In this research study, the investigators are looking to determine the safety and efficacy of an investigational drug, STA9090 alone and in combination with dutasteride for the treatment of castrate resistant prostate cancer. STA9090 may cause the growth of cancer to slow down or shrink by targeting proteins required for the cancer to grow. The investigators are also looking to determine whether the use of dutasteride to lower male hormone levels will enhance the effect of STA9090 in the treatment of castrate resistant prostate cancer.
