Registered outcomes2
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Change is assessed of cranaial arteries; MMA, STA and MCA | Before and after infusion of levcromakalim compared with before and after infusion of saline. Time of measurements is baseline, 20 min, 110 min, 200 min, 290 min and 350 min after the infusion. | The investigator will obtain repeated MRA measurements covering the diameter of MMA and MCA before and after levcromakalim/placebo infusion. |
| Secondary | Headache | Before (-10 min) and after infusion (+16 hours) of levcromakalim compared with before and after infusion of saline | Headache intensity will be recorded on a verbal rating scale (VRS) from 0 to 10 (0, no headache; 1, a feeling of pressure; 10, worst imaginable headache). Time of headache measurements is before (-10 min) and after infusion (+16 hours) of levcromakalim compared with before and after infusion of saline |
