FDA Approves 2 Upsher-Smith sNDAs for Migraine Drug

FDA has approved two Upsher-Smith Laboratories supplemental NDAs for Qudexy XR (topiramate) Extended-Release Capsules for use in preventing migraine headache in adults and adolescents 12 years of age and older. Topiramate is the active ingredient in Janssen Pharmaceuticals’ Topamax (topiramate) and is the molecule that neurologists prescribe most frequently for the prevention of migraines, according to the company.


Qudexy XR has been engineered to deliver a level pharmacokinetic profile and was shown to reduce the peak-to-trough fluctuation of topiramate plasma concentrations that are associated with immediate-release topiramate, the company says. Upsher-Smith has also agreed to address post-marketing requirements with a study to evaluate the efficacy and safety of Qudexy XR for preventing migraine in pediatric patients aged 6-11.
