Demonstrated efficacy in preventing
migraine attacks1

VYDURA* Significantly Reduces Monthly Migraine Days (MMDs)2Reduction in Migraine Frequency Within the First Week and First Month of Treatment With VYDURA*2,3

Post hoc analysis of an exploratory endpoint. The analysis of this endpoint at Week 1 was not tested in hierarchical order or adjusted for multiplicity. Subjects had ≥1 day of efficacy data in the observation period and ≥1 week in the double-blind treatment phase.3,4

There was a greater reduction in the number of migraine days during the first month of treatment compared to placebo (-2.9 vs -1.7, P<0.0001, nominal P value, and not controlled for multiplicity).2 

VYDURA* demonstrated long-term efficacy for preventing monthly migraine days (MMDs)1
  • Efficacy was sustained for up to an additional 12 months during the open-label study extension in which patients received VYDURA1*
  • In these patients, the overall mean reduction from baseline in the number of MMDs averaged over the 16-month treatment period was 6.2 days1
