Study type
Interventional
Description of intervention(s) / exposure
A randomised, double-blinded parallel group controlled study to evaluate the safety and efficacy of eptinezumab against lignocaine in the inpatient treatment of status migrainosus.

Participants randomised to the Eptinezumab arm will receive 300mg via intravenous infusion over 30 minutes followed by placebo infusion (saline) for up to five days or until the migraine is aborted.
Intervention code [1] 322016 0
Treatment: Drugs
Comparator / control treatment
The control treatment for this study is lignocaine as per standard treatment for status migrainosus at the study site.

Participants randomised to the lignocaine arm will receive a placebo (saline) intravenous infusion for 30 minutes followed by lignocaine 2mg/min via intravenous infusion for up to five days (as per site standard procedure) or until the migraine has been aborted.

The placebo infusion for both groups will be identical.
