Brief summary in scientific language

This study delves into the complex relationship between hormones, specifically oxytocin, and migraine attacks. Migraine, affecting 15% of the global population, poses a significant health burden, especially for women. Hormonal fluctuations, especially during menstruation, have been associated with triggering migraines. While the focus was historically on estrogen, attention has now shifted to alternative hormones, with oxytocin emerging as a key player. In this placebo-controlled, double-blind, randomized human provocation study using a commercially available oxytocin receptor antagonist (atosiban), our goal is to investigate the impact of inhibiting oxytocin as a migraine trigger and understand the underlying pathophysiological pathways involved in migraine. We hypothesize that an inhibited effect of oxytocin due to receptor antagonism will lead to migraine-like attacks in women with migraine. Beyond examining oxytocin antagonization as a trigger for migraine attacks, our study seeks to uncover the underlying mechanisms by exploring its impact on vascular parameters and serological migraine biomarkers, such as calcitonin gene-related peptide (CGRP). Continuous hormonal contraception is implemented as an inclusion criteria to minimize the influence of fluctuating sex hormones. A control group of men with migraines is included to assess sex-specific impacts. Previous human provocation studies indicate that only individuals with migraines experience provoked attacks, while healthy volunteers, at most, develop a mild headache. Therefore, another control group comprisin healthy women without migraine using a continuous hormonal contraception will be included. Both control groups will undergo the same study protocol. In summary, this investigation seeks to advance our understanding of hormone-dependent aspects of migraine pathophysiology, potentially paving the way for innovative therapeutic interventions centered around the oxytocin pathway.

Interventions, Observational Groups

Arm 1:
Women with migraine using continuous hormonal contraception. Participants will receive an intravenous infusion of atosiban (6.75mg, equivalent to 0.9ml, as a bolus over 1 minute, followed by an additional 30.75mg, equivalent to 4.1ml, over 1.5 hours) or placebo (0.9ml NaCl as a bolus over 1 minute, followed by 4.1ml NaCl/min over 1.5 hours) via a peripheral intravenous access in the cubital vein. Following the cross-over design, patients who received atosiban at the first visit will receive placebo at the second visit, and vice versa. There must be a minimum of 7 days between the first and second visits.
Arm 2:
Men with migraine. Participants will receive an intravenous infusion of atosiban (6.75mg, equivalent to 0.9ml, as a bolus over 1 minute, followed by an additional 30.75mg, equivalent to 4.1ml, over 1.5 hours) or placebo (0.9ml NaCl as a bolus over 1 minute, followed by 4.1ml NaCl/min over 1.5 hours) via a peripheral intravenous access in the cubital vein. Following the cross-over design, patients who received atosiban at the first visit will receive placebo at the second visit, and vice versa. There must be a minimum of 7 days between the first and second visits.
Arm 3:
Healthy women using continuous hormonal contraception. Participants will receive an intravenous infusion of atosiban (6.75mg, equivalent to 0.9ml, as a bolus over 1 minute, followed by an additional 30.75mg, equivalent to 4.1ml, over 1.5 hours) or placebo (0.9ml NaCl as a bolus over 1 minute, followed by 4.1ml NaCl/min over 1.5 hours) via a peripheral intravenous access in the cubital vein. Following the cross-over design, patients who received atosiban at the first visit will receive placebo at the second visit, and vice versa. There must be a minimum of 7 days between the first and second visits.

Endpoints

Primary outcome:
Incidence of migraine-like attacks within a 12-hour observation period following administration of atosiban vs. placebo in women with migraine using continuous hormonal contraception.
Secondary outcome:
Incidence of headache attacks (all kinds) within a 12-hour observation period following administration of atosiban vs. placebo in women with migraine under continuous hormonal contraception / men with migraine / healthy female controls under continuous hormonal contraception. Headache intensity within a 12-hour observation period following administration of atosiban vs. placebo in women with migraine under continuous hormonal contraception / men with migraine / healthy female controls under continuous hormonal contraception. Changes in mean arterial blood pressure following administration of atosiban vs. placebo in women with migraine under continuous hormonal contraception / men with migraine / healthy female controls under continuous hormonal contraception, calculated as the area under the curve (AUC) between baseline and 180 minutes after migraine induction. Changes in mean heart rate following administration of atosiban vs. placebo in women with migraine under continuous hormonal contraception / men with migraine / healthy female controls under continuous hormonal contraception, calculated as the AUC between baseline and 180 minutes after migraine induction. Changes in the diameter of the superficial temporal artery following administration of atosiban vs. placebo in women with migraine under continuous hormonal contraception / men with migraine / healthy female controls under continuous hormonal contraception, calculated as the AUC between baseline and 180 minutes after migraine induction. Changes in blood flow velocity of the middle cerebral artery following administration of atosiban vs. placebo in women with migraine under continuous hormonal contraception / men with migraine / healthy female controls under continuous hormonal contraception, calculated as the AUC between baseline and 180 minutes after migraine induction. Changes in CGRP levels in saliva following administration of atosiban vs. placebo in women with migraine under continuous hormonal contraception / men with migraine / healthy female controls under continuous hormonal contraception, calculated as the AUC between baseline and 180 minutes after migraine induction.
