Clinical Trial Summary

This double-blind, randomized, placebo-controlled cross-over clinical trial aims to investigate the effects of riocigaut on migraine inducing properties and cerebral arteries in patients with migraine.


Clinical Trial Description

The investigators believe that activation of sGC could play a role in migraine pathophysiology and propose that stimulation with riociguat causes migraine attacks alongside cranial arterial dilation in patients with migraine. Twenty-one patients with migraine will participate at a screening visit and, if eligible, on two separate study days, where participants, in a randomized cross-over fashion, will ingest either riociguat (active comparator arm) or placebo (placebo comparator arm), serving as their own controls. On the two separate study days the investigators will measure change in diameter of superficial temporal artery and middle cerebral artery blood flow velocity, heart rate, blood pressure and register possible headache/migraine including associated symptoms until 6 hours after intake of riociguat or placebo. At home participants are expected to fill out a headache diary until 12 hours from intake of riociguat or placebo. ;
