A Pilot Study to Enhance F18 FDG-PET Imaging of Prostate Cancers With the Metabolic Inhibitor Ranolazine

November 29, 2018 updated by: University of Colorado, Denver
This pilot clinical trial studies fludeoxyglucose F18 (FDG)-positron emission tomography (PET) in imaging patients with prostate cancer treated with ranolazine. Diagnostic procedures, such as FDG-PET, may help find prostate cancer and find out how far the disease has spread. Giving ranolazine may enhance FDG-PET imaging by increasing the amount of glucose available for uptake by the scan.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

PET scans have traditionally not been very good at detecting prostate cancers. This is because prostate cancer cells do not take up glucose well so the signals are very weak. The ability of PET imaging to detect cancers requires that the cancer cells take up glucose into the cells. Different methods are being tested to see if we can improve the detection of prostate cancers using PET scans.

Ranolazine is a drug that is already approved by the FDA for treatment of chronic chest pain in people with heart disease. Ranolazine has been studied in the laboratories at the University of Colorado Denver, Anschutz Medical Campus. Ranolazine has been added to prostate cancer cells and grown in petri dishes and in animals in the laboratory. It has been shown to increase the glucose uptake of prostate cancer cells. The goal of this study is to see if patients taking ranolazine will have better PET imaging of their prostate cancers.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

19 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No
