Ticagrelor Therapy for RefrACTORy Migraine Study

Phase 4

Completed

• Conditions: Migraine; Headache; Migraine Headache
• Interventions: Drug: Ticagrelor 90 mg twice per day

• Registration Number: NCT02518464
• Lead Sponsor: Columbia University

Brief Summary

This is a prospective, open-label, single-arm pilot study treating 40 subjects to assess the hypothesis that P2Y, G protein-coupled 12 (P2Y12) inhibition with Brilinta/ticagrelor (90 mg by mouth (PO) twice a day) reduces episodic and/or chronic migraine headache symptoms in patients with right to left shunt. Headache frequency while on Brilinta/ticagrelor will be compared with the documented baseline for each subject. If the Brilinta/ticagrelor therapy was effective (\> 50% reduction in monthly headache days), the subject could elect to continue therapy for an additional two months (56 days), while continuing to complete daily headache logs.

Detailed Description

Migraine headaches are poorly understood, and can be severely debilitating. Many types of drugs have been tried in migraine sufferers including anti-depressants, anti-seizure medications, blood pressure medicines and others. The investigators have shown that in a small number of patients, a certain type of blood thinner (Clopidogrel) can reduce or eliminate migraine headaches in patients who also have a hole in the heart wall that allows flow from the right side of the heart to the left. Ticagrelor is a blood thinning drug which works in the same way as the clopidogrel, but is broken down by the body differently and thus allows everyone to use it. The investigators wish to test this medication to see if it works as well, or better than the clopidogrel.

Arm && Interventions

Group	Intervention	Description
Ticagrelor 90 mg twice per day	Ticagrelor 90 mg twice per day	Interventions include the following: All participants will have a loading dose of Ticagrelor (Brilinta) 180 mg administered in the office at the time of enrollment. Thereafter, for 28 days, Ticagrelor 90 mg tablet will be taken once in the morning and once in the evening, as close to 12 hours apart as possible. Each day, the subject will receive a text message reminder to login to the website, to record her/his headache activity.

Primary Outcome Measures

Name	Time	Method
Total Number of Responders	1 month from baseline	A participant will be considered to have achieved the primary efficacy endpoint (a "Responder") if she/he has \>50% reduction in the number of monthly headache days during the month of therapy compared with participant's own baseline. If there is \< 50% reduction in the number of migraine days, she/he will be considered a Non-Responder.
