About this trial
The goal of this observational study is to compare, in real-world clinical practice, the effect of fremanezumab on menstrual migraine to the effect of fremanezumab on non-perimenstrual attacks. The main question it aims to answer is, if menstrually-related migraine attacks respond equally well to anti-CGRP mAb treatment with fremanezumab as non-menstrually-related attacks.
Participants diagnosed with episodic or chronic migraine with menstrually-related migraine with or without aura and treated with fremanzumab according to the SmPC will be required to maintain a headache diary over at least 3 months prior to and 6 months after fremanezumab initiation.

Trial population
Premenopausal women ≥18 years of age, diagnosed with episodic or chronic migraine, with menstrually-related migraine with or without aura according to IHS Classification (ICHD-3 code A1.1.2 or A1.2.0.2)\*, and have been prescribed fremanezumab according to the SmPC as a treatment decision of their physician and enrollment in this study at baseline.

Treatments tested in this trial
Fremanezumab
DrugInitiation of anti-CGRP mAb (fremanezumab) treatment according to the Summary of Product Characteristics (SmPC) during clinical routine as a treatment of their physician (no study-specific intervention). This means that patients have to fulfil criteria for treatment with anti-CGRP mAbs in Switzerland, i.e. they have at least 8 days of migraine per month in the last three months.
Treatment groups
Trial outcomes
Primary outcomes
Change of migraine days per month
Difference in relative reduction of migraine days per month between menstrually-related and non-menstrual migraine days at follow-up (months 4 to 6 after initiation of anti-CGRP mAb) compared to baseline (months -3 to -1 prior to initiation).
Secondary outcomes
Change of disability score MIDAS in points
Change from baseline in disability score, as measured by the Migraine Disability Assessment (MIDAS) questionnaire, at month 6.
Change of headache-related disability score HIT-6 in points
Headache-related disability score, as measured by the HIT-6, at month 6.
Migraine-specific quality of life in MSQ score in points
Migraine-specific quality of life, as measured by the MSQ version 2.1, at month 6.
Anxiety in GAD-7 score, in points
Change from baseline in anxiety (GAD-7).
