EMBRACE-OBS is the first phase of the EMBRACE research program. This single-site observational registry accesses and analyzes patient-reported outcome data already collected through routine clinical care from adults with migraine who have undergone or plan to undergo middle meningeal artery (MMA) embolization. The study describes changes in headache frequency, headache severity, medication use, migraine-related disability, quality of life, and reported adverse events over time without influencing clinical care.
EMBRACE-OBS is the first phase of the EMBRACE research program and is conducted as a single-site observational registry at Cortex Neurovascular.
Migraine is a prevalent neurological disorder that can significantly affect quality of life and daily functioning. Middle meningeal artery (MMA) embolization is performed using FDA-cleared embolic devices. When used for migraine, the procedure is performed at the discretion of the treating physician as part of routine clinical care and independent of research participation.
The purpose of this registry is to access and analyze clinical and patient-reported outcome data already collected through routine clinical care in patients who have undergone or plan to undergo MMA embolization for migraine. The study does not influence clinical decision-making, procedural technique, device selection, or follow-up care.
The primary objective is to describe changes in patient-reported headache frequency and severity over time following MMA embolization performed as part of routine clinical care.
Secondary objectives include describing changes in acute headache medication use, migraine-related disability, quality-of-life measures, medication use patterns, temporal patterns of symptom change, and the real-world safety profile of the procedure as reflected by reported adverse events and complications.
Patient follow-up occurs through routine clinical care. Data accessed for this registry may include headache diaries, HIT-6 scores, clinical information, procedural information, medication use, and outcomes documented during routine clinical follow-up visits. No study-mandated interventions, procedures, visits, or assessments are performed. The research activity consists solely of accessing and analyzing information already documented during routine care.
EMBRACE-OBS is conducted under a separate IRB-approved protocol (Solutions IRB Study 2026-Jun-1013). A separate interventional phase of the EMBRACE research program (EMBRACE-Full; NCT07313800) may be conducted in the future under appropriate regulatory approvals.
1,657 studies on the registry are indexed under Migraine Disorders; 339 are open to participants now.
This study's planned enrollment of 50 is below the median of 137 across 331 observational studies indexed under Migraine Disorders.

Adults aged 18 to 64 years with a diagnosis of migraine who have undergone or plan to undergo middle meningeal artery (MMA) embolization as part of routine clinical care at Cortex Neurovascular. Participants are enrolled in a prospective observational registry that accesses and analyzes clinical and patient-reported outcome data already documented during routine care. Enrollment does not influence clinical decision-making, procedural technique, device selection, or follow-up care.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Procedure: Middle Meningeal Artery Embolization
Middle meningeal artery (MMA) embolization performed as part of routine clinical care at the discretion of the treating physician. The procedure is independent of study participation and is not assigned by the study protocol. The research activity consists solely of accessing and analyzing data already documented through routine clinical care.
Change in Patient-Reported Headache Frequency
Change in patient-reported headache frequency, measured as headache days per month, from baseline to 12 months following middle meningeal artery (MMA) embolization performed as part of routine clinical care.
Time frame: Baseline and 12 Months
Change in HIT-6 Score
Change in migraine-related disability as assessed by the Headache Impact Test (HIT-6) score (range: 36-78; higher scores indicate greater headache impact/worse outcome) documented during routine clinical care.
Time frame: Baseline and 12 Months
