Summary

This study tests the long-term safety of eptinezumab (Vyepti) in 600 children and teens aged 6 to 17 with chronic or episodic migraine. Participants must have completed a prior study. The main goal is to track side effects over time, with additional measures of drug levels and immune response.

What this could mean

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

Active substance
eptinezumab (Vyepti)
What this could lead to
If successful, this could confirm that eptinezumab is a safe long-term option to reduce migraine frequency in children and teens.
What could go wrong
This is an extension study focused on safety, not effectiveness. It may not show strong benefits, and side effects or lack of response could limit its use.

This is an AI summary of the original study and may miss details. Read our disclaimer.
