NCT ID: NCT03356912 Enrolling by invitation - Prostate Cancer Clinical Trials

CABAzitaxel With or Without Prednisone in Patients With Metastatic CAstration REsistant Prostate Cancer Progressed During or After a Previous Docetaxel-based Chemotherapy

Start date: November 22, 2017
Phase: Phase 2
Study type: Interventional

Patients with metastatic castration resistant prostate cancer (mCRPC) progressed during or after a previous docetaxel-based chemotherapy, for whom cabazitaxel has been scheduled as per clinical practice and label indication. In the "TROPIC" Trial, cabazitaxel, administered concomitantly with prednisone 10 mg daily, showed a significant advantage vs. mitoxantrone in both Overall Survival (OS) and Progression Free Survival (PFS) / radiographic PFS in patients failing docetaxel-based chemotherapy. Similar to docetaxel, cabazitaxel has been approved in combination with daily prednisone, but the benefits of adding daily corticosteroids to taxane chemotherapy remain to be proven. In fact, corticosteroids have a variety of biological effects, and a number of studies in large cohorts of patients show that they may have both favourable effects, mediated by adrenal androgen and cytokine suppression, and detrimental effects related to their adverse events associated with their long-term use as well to the potential promiscuous activation of the AR. In fact, prednisone and dexamethasone can activate some AR variants that make tumors sensitive to glucocorticoids even at low concentrations. It has been showed that point mutations of the AR, which appear to cluster in the ligand-binding domain, are rare in therapy naive patients but occur in 15- 45% of patients with castration-resistant disease and can increase AR affinity for a wide range of steroids. On the other hand, insofar as safety is concerned, omitting daily corticosteroids does not seem to increase toxicity (e.g. hypersensitivity reactions). In fact, in the CHARTEED trial, docetaxel was safely administered without daily corticosteroids. Safety data about the use of cabazitaxel without daily prednisone/prednisone alone are missing. The CABACARE study is designed to assess the effects in terms of efficacy, safety as well as quality of life of omitting daily corticosteroids in patients treated with cabazitaxel. Furthermore, the CABACARE study evaluates the mutational status of the RB gene as well as presence of AR-V7 variant. The AR-V7 status assessed in circulating tumor cells has a strong predictive value for abiraterone/enzalutamide effectiveness, but its role in patients receiving cabazitaxel requires to be defined.

Ketogenic Diet and Prostate Cancer Surveillance Pilot

GCC 1717
Start date: June 12, 2017
Phase: N/A
Study type: Observational

Men with indolent forms of prostate cancer are managed expectantly using active surveillance, with a goal of delaying treatment and its deleterious side effects. However, almost 50% of men experience progression with this approach and require treatment. Elevated body mass index (BMI) is associated with a dramatically increased risk of progression to higher grade prostate cancer. The goal of the proposed research is to gather preliminary data evaluating the effects of a promising dietary strategy to delay cancer progression in overweight and obese prostate cancer patients undergoing active surveillance. The investigators hypothesize that a ketogenic diet intervention may reduce BMI and favorably alter the prostate microenvironment.

Prospective Validation of Prostate Biomarkers for Repeat Biopsy

PRIORITY
Start date: March 31, 2017
Phase: N/A
Study type: Observational

Target enrollment is 1000 prospectively enrolled subjects with an initial negative biopsy scheduled for repeat biopsy. Subjects must have had their negative index prostate biopsy procedure within 30 months of being scheduled for their repeat biopsy. All enrolled subjects will have all core tissues from the initial negative biopsy blinded and tested with the assay. All subjects will have serum and plasma samples obtained prior to DRE, and a urine sample collected immediately following DRE but in advance of the repeat biopsy; samples will be blinded and sent to MDxHealth for evaluation.

Correlation Between SUV on 18F-DCFPyL PET/CT and Gleason Score in Prostate Cancer

Start date: July 1, 2017
Phase: Phase 2
Study type: Interventional

Prostate specific membrane antigen (PSMA) is a unique membrane bound glycoprotein, which is overexpressed manifold on prostate cancer cells and is well-characterized as an imaging biomarker of prostate cancer. Positron emission tomography / computer tomography (PET/CT) is a nuclear medicine procedure based on the measurement of positron emission from radiolabeled tracer molecules. 18F-DCFPyL is a tracer for prostate cancer PET imaging which binds to PSMA. The strength of functional imaging methods is in distinguishing tissues according to metabolism rather than structure. Studies have shown that PET/CT imaging with 18F-DCFPyL can detect prostate cancer lesions with excellent contrast and a high detection rate even when the level of prostate specific antigen is low. The objective of this study is to evaluate if the patient-wide SUVmax on 18F-DCFPyL PET/CT in locoregional and metastatic prostate cancer correlates with histopathologic Gleason score at initial biopsy. It is hypothesized that SUVmax will correlate positively with Gleason score. This is of interest because non-invasive risk stratification may be possible in the future.

The Safety and Efficacy of 18F-Fluoromethylcholine (18F-FCH) PET/CT in Prostate Cancer

Start date: September 2016
Phase: Phase 3
Study type: Interventional

The objectives of this study are to confirm the safety and efficacy of FCH-PET/CT and to establish our ability to reproduce results from the literature using FCH-PET/CT as a diagnostic and decision making tool in the management in two predefined groups of prostate cancer patients, specifically, biochemical recurrence and high risk staging. The primary endpoints of the study are the incidence of adverse events (AE) in the study population up to 24 hours following the scan, and the sensitivity and specificity of FCH-PET/CT vs CT on a per-patient and per-lesion basis.

NCT ID: NCT02796807 Enrolling by invitation - Prostate Cancer Clinical Trials

Correlation Between SUV on 68Ga-HBED-CC-PSMA and Gleason Score in Prostate Cancer

Start date: May 2016
Phase: Phase 2
Study type: Interventional

Prostate cancer is the second leading cause of cancer death in North American men older than 50 years. Prostate specific membrane antigen (PSMA) is a unique membrane bound glycoprotein, which is overexpressed manifold on prostate cancer cells and is well-characterized as an imaging biomarker of prostate cancer. Positron emission tomography / computer tomography (PET/CT) is a nuclear medicine procedure based on the measurement of positron emission from radiolabeled tracer molecules. 68Ga-HBED-CC-PSMA (DKFZ-11) (abbreviated 68Ga-PSMA) is a tracer for prostate cancer PET imaging. The strength of functional imaging methods is in distinguishing tissues according to metabolism rather than structure. Studies have shown that PET/CT imaging with 68Ga-PSMA can detect prostate cancer lesions with excellent contrast and a high detection rate even when the level of prostate specific antigen is low. Study Objectives: The objective of this study is to evaluate if the patient-wide SUVmax on 68Ga-PSMA PET/CT in locoregional and metastatic prostate cancer correlates with histopathologic Gleason score at initial biopsy. It is hypothesized that SUVmax will correlate positively with Gleason score. This is of interest because non-invasive risk stratification may be possible in the future. This will be a single-site JGH-only open label study in which one (1) 68Ga-PSMA PET/CT will be performed on study participants. A PET/CT scan takes 2-3 hours.

Fusion Guided Focal Laser Ablation of Prostate Cancer

Start date: April 22, 2016
Phase: Phase 3
Study type: Interventional

Background: Prostate cancer is the most common non-skin cancer in U.S. men. Treatments for early or less aggressive disease are limited. Researchers want to test a device that destroys cancerous tissue with laser energy. They want to see if using it with ultrasound is more comfortable than using it with magnetic resonance imaging (MRI). Objectives: To test a cooled laser applicator system to treat prostate cancer lesions. To see if ultrasound imaging is a practical and feasible treatment with laser ablation for focal prostate cancer treatment. Eligibility: Men at least 18 years old with prostate cancer seen on MRI that has not spread in the body. Design: Participants will be screened with standard cancer care tests. These can include physical exam, lab tests, and MRI. For the MRI, they lie in a machine that takes pictures. Participants will have a prostate biopsy. Needle samples will be taken from 12 places in the prostate. This will be guided by MRI and ultrasound, which is obtained through a coil in the rectum. Participants will stay at the clinic for 1 2 days. A cooling catheter (plastic tube) will be put in the bladder. Ultrasound will guide the laser applicator directly to the tumor. The cooling catheter will be removed. A different catheter will be put in the urethra to keep the bladder emptied. The next day, participants will have a physical exam and a PSA blood test. Participants will have 6 follow-up visits over 3 years. At each visit, they will have a physical exam and lab tests. At some visits, they will also have an MRI or other scans and a prostate biopsy.
