Neurocrine Announces Plans to Resubmit NDA for Indiplon Capsules in Q2 2007

SAN DIEGO, Jan. 22 (HSMN NewsFeed) -- Neurocrine Biosciences, Inc. (Nasdaq: NBIX ) announced today that the Company plans to resubmit its New Drug Application (NDA) for indiplon capsules by the end of 2nd Quarter 2007. The decision to accelerate the resubmission is based on the results of interactions with the Food and Drug Administration (FDA) regarding further analyses of data previously submitted on indiplon capsules, as well as reviewing this data with independent statistical, regulatory and clinical consultants. Neurocrine expects that the FDA will characterize the resubmission as Class 2 which has a targeted review timeline of 6 months.

"We believe that indiplon will offer an important new alternative for the treatment of insomnia by providing flexibility to treat insomnia as needed, to help patients quickly fall asleep or return to sleep after a nighttime awakening," said Gary Lyons, President & CEO of Neurocrine Biosciences.

The Company's discussions with the FDA on the indiplon capsules NDA have been focused on the actions necessary to provide a complete response to the agency's questions thus allowing for its resubmission. The FDA requested that the resubmission include further analyses and modifications of analyses previously submitted to address questions raised by the Agency in its initial review. The FDA also requested, and the Company has completed, a supplemental pharmacokinetic/food effect profile of indiplon capsules including several meal types. No other trials were requested for the re-submission. The Company has decided that it will not conduct an additional 3-month safety and efficacy study as previously announced but rather direct these resources to pre-commercialization and Phase IIIb/IV activities as well as to continue to evaluate indiplon for traditional sleep maintenance.
