FDA Delays Approval for Migraine Drug Trexima

Trexima, a combination of sumatriptan (Imitrex) and naproxen sodium (found in Aleve and other NSAIDs), was expected to receive FDA approval last week. Requesting more safety data, the FDA has delayed approval of Trexima.

The concern is about one of the four tests of genotoxicity, which is toxicity to DNA. The requested data are available from a study that has already been conducted. The FDA will meet with Pozen and GSK soon to discuss additional requirements.
