Summary
The goal of this clinical research study is to learn if giving metformin in combination with
radiation therapy is more effective than radiation therapy alone. In this study,
participants will receive either metformin or a placebo. A placebo is not a drug. It looks
like the study drug but is not designed to treat any disease or illness. It is designed to
be compared with a study drug to learn if the study drug has any real effect.
Clinical Details
Official title: Tumor Mutation Status Will Predict Metabolic Response to Metformin in Non Small Cell Lung Cancer (NSCLC)
Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment
Primary outcome: Tumor Response Between Metformin and Placebo Cohorts
Secondary outcome: Genotype Comparisons of Kras, STK11, and TP53 Mutations
Detailed description:
Study Groups:
If you are found to be eligible to take part in this study, you will be randomly assigned
(as in the roll of dice) to receive either metformin or a placebo. This is done because no
one knows if one study group is better, the same, or worse than the other group. For every
7 participants enrolled in this study, 6 will receive metformin and 1 will receive a
placebo.
Only the study staff will know if you are receiving the study drug or the placebo.
Study Drug/Placebo Administration:
You will begin taking metformin/placebo 3 weeks before you begin radiation therapy. You
will take it each week during radiation therapy. You will take the drug/placebo 3 times a
day (in the morning, at noon, and in the evening).
To decrease the GI side effects you will start metformin at 1000 mg daily in a divided dose
(in the morning and in the evening) for 1 week.
You will keep a log for each time that you take metformin/placebo. You should bring the log
with you to each study visit.
You will also receive Benadryl (diphenhydramine) and prednisone to help prevent side
effects.
There will be no change to your radiation therapy. You will receive a separate consent form
that describes the radiation therapy and its risks.
Study Visits:
Every week while you are taking the study drug/placebo, blood (about 2-3 teaspoons) will be
drawn for routine tests.
You will have a positron emission tomography-computed tomography (PET-CT) scan 3 weeks after
starting metformin/placebo to check the status of the disease.
Length of Study:
You may continue taking the study drug/placebo for up to a total of 2 weeks during radiation
treatment. You will no longer be able to take the study drug/placebo if the disease gets
worse, if intolerable side effects occur, or if you are unable to follow study directions.
Follow-Up:
Your medical records will be checked for up to 6 months after your SBRT.
This is an investigational study. Metformin is FDA approved for the treatment of diabetes.
Its use in this study to be given with radiation therapy to treat lung cancer is
investigational. The study doctor can explain how the study drug is designed to work.
Up to 70 participants will be enrolled in this study. All will take part at MD Anderson.
Eligibility
