Evaluation of MIG-SPRAY Treatment on Migraine

The goal of this clinical trial is to evaluate the real-world tolerability of the MIG-SPRAY device in adults aged 18-55 diagnosed with migraine (according to nternational Classification of Headache Disorders 3rd edition, code 1.1(ICHD-3)) for over 1 year. The main questions it aims to answer are: * Does MIG-SPRAY significantly reduce the composite score of expected adverse events (e.g., allergic reactions, nausea, headache) compared to no intervention, graded via a Likert scale (using the Common Terminology Criteria for Adverse Event (CTCAE v5.0))? * Are there differences in unexpected adverse events, monthly migraine frequency, or Migraine Disability Assessment (MIDAS) scores between groups? Researchers will compare the intervention group (MIG-SPRAY) to the control group (no device) to assess: 1. Tolerability (primary outcome). 2. Unexpected adverse events, migraine frequency, and disability (secondary outcomes). Participants will: * Be randomized (2:1) to MIG-SPRAY (n=30) or control (n=15). * Use an electronic diary daily to report adverse events and migraine episodes. * Complete the MIDAS questionnaire at baseline and post-treatment. * Undergo monthly physician calls to review and grade adverse events. Study design: * Post-marketing, monocentric, open-label, randomized trial (Clermont-Ferrand University Hospital). * Category 4.2 clinical investigation (CE-marked Class I device, used per labeling). * No changes to background migraine therapy permitted. Key eligibility: * Age 18-55, migraine diagnosis ≥1 year (ICHD-3). * Effective contraception (females of childbearing potential). * Social security coverage and written informed consent.
