The US agency, which has a preliminary 60-day period to decide whether there will be a full review of the dossier submitted after a New Drug Application (NDA) is submitted, decided that the US company’s application was not sufficiently complete.

Its ruling raises important questions concerning the way the FDA interprets requirements for stability data, said Adventrx’s chief executive Brian Culley.
