Summary

This study tests whether galcanezumab, a monthly injection, can prevent chronic migraine in 312 adolescents aged 12 to 17. Participants receive either the drug or a placebo for 3 months. The main goal is to see if the drug reduces the number of migraine days per month.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance

What this could lead to
If it works, this could give teens with chronic migraine a new preventive option to reduce headache days.
What could go wrong
This is a single phase 3 trial; results may not confirm benefit. Side effects or lack of efficacy are possible.
