    Biovail Reports Second-Quarter 2007 Financial Results  Aug 8, 2007
    The issue raised by the FDA in its letter related to the design of the pharmacokinetic studies required to support the NDA. Biovail's NDA included a single-dose, fed and fasted bioavailability study; a single-dose, dose-proportionality study; and a multiple-dose, bioequivalence (BE) study comparing BVF-033 to bupropion hydrochloride. The FDA contends that a single-dose, comparative BE study should have been conducted instead of the multiple-dose BE study in Biovail's NDA. Biovail believes the... (Canada Newswire)
