New hope for teens with chronic migraines?
NCT ID NCT04965675
First seen Jun 27, 2026 · Last updated Aug 21, 2026 · Updated 3 times
Summary
This study tests whether eptinezumab, given as an IV infusion, can reduce the number of migraine days in adolescents aged 12 to 17 who have chronic migraine (15 or more headache days per month). Participants will receive either the drug or a placebo (salt water) and track their headaches for 12 weeks. The goal is to see if the drug safely and effectively prevents migraines better than placebo.
