A Pilot Study Using 18F-DOPA PET-guided Radiotherapy in Gliomas

Study Purpose

For most brain tumors, radiation treatment is guided by a Magnetic Resonance Imaging (MRI) scan. In this study, information from a special scan, called a Positron Emission Tomography/ Computed Tomography (PET/CT) scan using an amino acid called Fluorine-18-L-dihydroxyphenylalanine (18F-DOPA) will also be used. This type of scan has shown promise in being able to better distinguish tumor from normal brain tissue and may help to more accurately plan radiation treatment. This type of scan can also assist the radiation oncologist in identifying the most aggressive regions of the tumor. The goal of this study is to compare the 18F-DOPA PET/CT scan with the MRI scan for identifying where the disease is that needs to be treated with radiation.

Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

No
Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.


An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.


Searching Both is inclusive of interventional and observational studies.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.

NCT02104310
Phase

Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Lead Sponsor

The sponsor is the organization or person who oversees the clinical study and is responsible for analyzing the study data.
