MET-PET for Newly Diagnosed Glioblastoma

Study Purpose

This research study is a prospective pilot study. The purpose of a pilot clinical study is to obtain preliminary data to support the reason for doing a larger clinical trial on testing the clinical effectiveness of an investigational intervention. "Investigational" means that the role of MET-PET scans is still being studied and that research doctors are trying to find out more about it. It also means that the FDA has not approved this intervention for your type cancer. In this research study, the investigators are evaluating whether or not MET-PET scans have value in predicting response to standard chemoradiation therapy in participants with newly-diagnosed glioblastoma. A standard treatment for glioblastoma is treatment with a combination of radiation therapy and chemotherapy with the drug temozolomide. In PET scans, a radioactive substance is injected into the body. The scanning machine finds the radioactive substance, which tends to go to cancer cells. With standard PET scans, the radioactive substance used is FDG. FDG goes to many areas of the normal brain which makes it difficult for use in distinguishing brain tumors from normal tissue. For the PET scans in this research study, the investigators are using a radioactive substance called MET, instead of the standard substance FDG. MET gets absorbed by cancer cells but not by normal brain and therefore may be better than FDG in evaluating brain tumors and therefore may be better than FDG in evaluating brain tumors and their response to treatment. In this research study, participants will receive standard chemotherapy and radiation therapy for glioblastoma as well as standard MRI scans. In addition, participants will undergo L-[Methyl]-11C Methionine Positron Emission Tomography (MET-PET) scans twice. The first MET-PET scan will occur after enrollment but prior to radiation therapy. The second MET-PET scan will occur approximately one month after completion of radiation therapy.

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.

 NCT01867593
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.

Additional Details

After agreeing to take part in this research study you will be asked to undergo some screening tests or procedures to confirm that you are eligible. Many of these tests and procedures are likely to be part of regular cancer care and may be done even if it turns out that you do not take part in the research study. If you have had some of these tests or procedure recently, they may or may not have to be repeated. The screening process will include the following: A medical history, performance status, physical exam, routine blood tests, assessment of your tumor, diagnosis confirmation and pregnancy test. If these tests show that you are eligible to participate in the research study, you will begin the study treatment. If you do not meet the eligibility criteria, you will not be able to participate in this research study. Within 3 weeks after your surgery you will undergo a MET-PET scan to define residual metabolic activity. After completion of radiation therapy at 1,3,5,7,9 and 11 months following radiation therapy you will undergo: a medical history, physical exam, assessment of your tumor by MRI, documentation of your current dose of steroids, blood tests and an evaluation for side effects. At one month after the completion of radiation therapy you will undergo the second and final MET-PET scan to assess response to therapy. After the 11 month follow-up visit, we would like to keep track of your medical condition for the rest of your life as part of our routine care. If we no longer see you in person in the clinic, we would like to do this by calling you on the telephone once a year to see how you are doing. Keeping in touch with you and checking your condition every year helps us look at the long-term effects of the research study.
