Vernalis plc: Endo Provides Update on FrovaŽ sNDA

08 April 2008

Vernalis plc (LSE: VER) today announces that Endo Pharmaceuticals Inc. has notified the US Food and Drug Administration (FDA) of the withdrawal of the supplemental new drug application (sNDA) without prejudice to refiling as afforded under 21 CFR 314.65 for Frova® (frovatriptan succinate) 2.5 mg tablets. This sNDA was for the additional indication of Frova® for the short-term (six days per month) prevention of menstrual migraine. Vernalis and Endo are continuing to evaluate the potential for Frova® for this indication and other related indications. In its business restructuring, announced on 20 February 2008, Vernalis based its strategy on the assumption that, for the immediate future, Frova® would only be approved for the acute treatment of migraine.
