About this study

Official title: Metformin for the Prevention of Episodic Migraine: a Randomized, Double-blind, Placebo-controlled, Crossover Study

The investigators will evaluate the safety and efficacy of metformin for preventive treatment of migraine in a randomized, double-blind, placebo-controlled, crossover trial.

Read the detailed description

This will be a single-center, double-blind, randomized, placebo-controlled, crossover study. The investigators will enroll 40 subjects. Subjects will be recruited from the outpatient Mayo Headache Clinic, Mayo Women's Health Clinic, Mayo Community Internal Medicine, and the Mayo Clinic- Arizona State University Neurology Clinic. The Headache Clinic employs 6 headache specialists and 1 fellow which is sufficient staffing to support this study and recruitment of patients with migraine.

Before study enrollment, patients will undergo a 2-hour oral glucose tolerance test to confirm the absence of diabetes mellitus.

Subjects will then keep a headache diary for 4 weeks to establish baseline characteristics, including number of migraine days per month, number of moderate to severe headache days per month, and number of days per month of acute medication use. The 4-week baseline period will be followed by 2 treatment periods of 12 weeks each, separated by a washout period of 4 weeks (total study duration, 32 weeks). For the 12-week treatment periods, subjects will receive either metformin 500mg twice daily or matching placebo twice daily.

Subjects will have 7 study visits. Routine laboratory studies and a pregnancy test will be performed at enrollment and week 20. Abnormal kidney or liver function will exclude subjects. Pregnancy will exclude subjects. General and neurologic examinations will be performed during 3 of the 7 visits. At each visit, subjects will receive medication for the period until the next visit. A headache diary will be used for the trial. For every day that the subject has a headache of any type, she or he will record headache characteristics, associated features, and medications used.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Metformin in people with Migraine, run by Mayo Clinic at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 1 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Jul 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Headache Days (time frame: Baseline through end of study for a total of approximately 32 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02593097, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 1 Jul 2020.
