Migraine Headaches Elimination With Patent Foramen Ovale-Directed Therapy

Criteria the registry did not label

• Patient Inclusion Criteria:
• Age: ≥18 and \<55 at time of screening
• Migraine headache with aura, or migraine headache without aura, fulfilling conditions of the Neurology Screening Tool (meeting ICHD-3 criteria)
• Diagnosis of migraine for ≥ 1 year; onset of migraine symptoms \< 40 years of age
• By history, an average headache burden of greater than one migraine headache day per week:
• without current preventative therapy, OR
• despite preventative therapy, OR
• with reason to come off effective therapy (e.g. cost, aversion to injections, side effects)
• If patient is taking preventive migraine medications, dose must be stable for at least 3 months prior to the screening visit. Patient agrees to continue preventive medication at the current dosage throughout the duration of the Baseline and On-treatment monitoring periods (Study Weeks 1 - 17).
• Female patients capable of becoming pregnant agree to use two forms of birth control or abstinence during their participation in the study.
  • Patient Exclusion Criteria:
  • Exclusions due to underlying patient medical issues:
• Headache disorder other than migraine with aura, or migraine without aura
• Patient has history of stroke, TIA, or intracranial hemorrhage.
• Patient has a history of thrombocytopenia within one year, or platelet count \<100,000/mm3 identified during the screening laboratory evaluation.
• Patient has severe hepatic impairment with reduced synthetic function as documented by prolongation of PT/PTT, or with total bilirubin \>3.0 mg/dL identified during the screening laboratory evaluation.
• Patient has previously implanted pacemaker, IVC filter, PFO closure device, ASD closure device, or left atrial appendage closure device or any cardiac history which, in the investigator's opinion, would preclude them from study participation.
• Patient has documented right-to-left shunt source in addition to PFO such as atrial septal defect or pulmonary arteriovenous malformation.
• Patient has a history of clinically significant bleeding within 6 months of the screening visit, any active bleeding, or active peptic ulcer disease.
• Patient has an uncontrolled arrhythmia, or if on therapy, has evidence of arrhythmia control failure within the past 90 days (e.g., supraventricular tachycardia or atrial fibrillation while under rhythm control).
• Patient has elevated PVR which in the opinion of the implanting physician precludes safe PFO closure.
• Patient has active infection at the time of screening that cannot be treated.
• Patient is planning surgery during the study timeframe.
• A female patient is pregnant or is planning pregnancy during the anticipated duration of the study. Urine or blood pregnancy screening will be performed as part of the screening laboratory evaluation.
• Patient has documented nickel allergy/sensitivity
• Patient has a documented history of non-compliance with medical care, which would preclude them, in the opinion of the study team
  • Exclusion Due to Medication Restrictions:
• Patient has known hypersensitivity or contraindication to thienopyridines
• Patient has another medical condition requiring chronic antithrombotic therapy with antiplatelet, oral anticoagulant or injectable agents
• Patient has need for daily use of NSAIDs other than for treatment of migraines
