January 30, 2017 updated by: Erik Mittra

To evaluate 18F-FDOPA PET obtained from PET/CT or PET/MRI imaging in patients with newly diagnosed or recurrent gliomas.

Study Overview

Status

Status

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

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

This clinical trial compares fluorine F-18 fluoro-dihydroxyphenylalanine (18F-fluorodopa or 18F-FDOPA) positron emission tomography (PET) with standard magnetic resonance imaging (MRI) in measuring tumors in patients with glioma that is newly diagnosed or recurrent (has returned). 18F-FDOPA is a radioactive drug that binds to tumor cells and is captured in images by PET. Computed tomography (CT) and MRI are used with PET to describe information regarding the function, location, and size of the tumor. PET/CT or PET/MRI may be more accurate than standard MRI in helping doctors find and measure brain tumors.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. 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

16 years and older (Child, Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Greater than 15 year-old at the time of radiotracer administration
  • Provides written informed consent
  • Suspected new diagnosis or suspected recurrence of glioma
  • Able to remain still for duration of each imaging procedure (about 20 minutes)

Exclusion Criteria:

  • Less than 15 year-old at the time of radiotracer administra
  • Unable to provide informed consent
  • Inability to lie still for the entire imaging time
  • Inability to complete the needed investigational and standard-of-care imaging examinations due to other reasons (severe claustrophobia, radiation phobia, etc.)
  • Any additional medical condition, serious intercurrent illness, or other extenuating circumstance that, in the opinion of the Investigator, may significantly interfere with study compliance

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Number of Suspicious Lesions Identified by 18F FDOPA PET
Time Frame: Up to 30 minutes after injection of F18 FDOPA
The number of suspicious lesions will be identified by uptake of F18 FDOPA radiopharmaceutical using a positron emission tomography (PET) scan. Uptake of F-18 FDOPA is a measure of amino acid uptake and metabolism in tumors. Suspicious lesions will be visually identified by a board certified nuclear medicine physician.
Up to 30 minutes after injection of F18 FDOPA
Percent Agreement of 18F FDOPA PET With Pathology
Time Frame: Up to 30 minutes post-injection (at time of scan)
For the subset of lesions where pathology is available (mainly biopsied lesions), the accuracy of 18F FDOPA PET as percent agreement with pathology will be calculated. If the number of biopsy positive lesions is at least 10, an estimate of sensitivity will be calculate; if the number of biopsy negative lesions is at least 10 an estimate of specificity will be calculated.
Up to 30 minutes post-injection (at time of scan)
