CGRP Inhibition, Autonomic Function, and Migraine

Austria120 participantsStarted 2020-10-01

Plain-language summary

The purpose of this clinical study is to better understand the function of the autonomic nervous system in patients with migraine. We aim to understand whether the autonomic functions change depending on the migraine status (i.e. whether they are between or during attacks) and whether the CGRP monoclonal antibody (mAb) class of drugs affects the autonomic functions. The aim is not to investigate the effect of CGRP-mAb on migraine frequency. Calcitonin gene-related peptide (CGRP) is a neurotransmitter in the nervous system that plays an essential role in the development of migraine headache. Monoclonal antibodies can block the function of this messenger substance. Several studies have shown that this blockade leads to a reduction in the frequency of migraine. In addition to its role in migraine, CGRP also acts on the blood vessels and the autonomic nervous system. The autonomic nervous system is responsible for everything we have no control over in our body. This includes everything from heart rate and blood pressure to our digestion.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
