Neurocrine Biosciences Reports Third Quarter 2008 Results

SAN DIEGO, Calif., Oct. 28 /PRNewswire-FirstCall/ -- Neurocrine Biosciences, Inc. today announced its financial results for the quarter ended September 30, 2008. For the third quarter of 2008, the Company reported a net loss of $17.7 million, or $(0.46) per share compared with a net loss of $27.2 million, or $(0.72) per share, for the same period in 2007. For the nine months, the Company reported a net loss of $59.8 million, or $(1.56) per share, as compared to $79.3 million, or $(2.09) per share, for the same period last year.

Revenues for the third quarter of 2008 were $0.8 million compared with $0.5 million for the same period last year. Revenues for the nine months ended September 30, 2008 were $3.2 million, compared with $0.7 million for the same period in 2007. The increase in revenues is primarily due to revenues recognized in 2008 under collaboration agreements with GlaxoSmithKline (GSK) and Dainippon Sumitomo Pharma Co., Ltd.

Research and development expenses decreased to $13.0 million during the third quarter of 2008 compared with $19.8 million for the same period in 2007. For the nine months ended September 30, 2008, research and development expenses were $43.4 million, compared to $57.6 million for the same period last year. The decrease in research and development expenses is primarily due to cost savings related to our restructuring in the fourth quarter of 2007.

General and administrative expenses were $3.5 million for the third quarter of 2008 and $9.6 million during the same period last year. For the nine months ended September 30, 2008, general and administrative expenses were $16.4 million, compared to $26.7 million for the first nine months of 2007. The reduction in general and administrative expenses is primarily due to cost savings related to recent restructurings.

The Company's balance sheet on September 30, 2008 reflected total assets of $207.7 million, including cash and investments of $118.2 million compared with balances at December 31, 2007 of $276.7 million and $179.4 million, respectively. The Company expects to end 2008 with approximately $100 million in cash and investments.

"We are pleased with the progress of our GnRH program, especially the recent positive results of our 603 study where once a day elagolix showed profound efficacy with minimal impact on bone mineral density. We are also nearing completion of the final preclinical studies of urocortin 2 to allow for long-term Phase II clinical studies and our scientists have just recently identified a clinical candidate from our VMAT2 development program for movement disorders," said Kevin Gorman, Chief Executive Officer and President of Neurocrine Biosciences. "While we are making great strides in advancing our pipeline, we continue to prioritize expenditures and diligently manage our cash burn."

R & D Pipeline Update

Neurocrine's clinical development group and corporate partners have five programs in clinical development. Neurocrine scientists continue to supply Neurocrine's pipeline to meet the Company-wide goal of bringing one new compound into development each year.

Elagolix for Endometriosis

The Company recently announced the positive safety and efficacy results from the completed 6-month treatment phase of its Phase IIb clinical trial (PETAL Study) using its proprietary, orally-active nonpeptide Gonadotropin-Releasing Hormone (GnRH) receptor antagonist, elagolix.

The primary endpoint, percent change from baseline in mean bone mineral density (BMD) demonstrated elagolix did not induce significant bone loss over the six month treatment period. Additionally, elagolix also met the secondary endpoints of improvement in endometriosis symptoms using several different scales for endometriosis pain. The 6-month results from this study, together with data from the other Phase II studies, will be the basis for securing agreement on a registration plan with the Food and Drug Administration (FDA).

The Company is also currently conducting two additional randomized placebo-controlled Phase II clinical trials. The clinical endpoints for both of these trials are a reduction in pelvic pain associated with endometriosis, utilizing a scale proposed by the FDA. The first Phase II trial includes our selected commercial formulation tablet in two doses, (150 mg and 250 mg); this trial has completed randomization in 155 patients. The Company expects topline results from the first three months of treatment in the first quarter of 2009. The second trial is a four arm comparator trial of two doses of elagolix (150 mg and 250 mg), placebo or leuprolide depot. This trial is being conducted in Central and Eastern Europe. Topline data from this 3-month double-blind trial of approximately 180 patients should be available at the end of the first half of 2009.

Neurocrine is also investigating the potential of certain GnRH antagonists in treating other hormone-dependent diseases in Men's and Women's Health.

Corticotropin Releasing Factor (CRF1) Receptor Antagonists for Anxiety/Depression and IBS

The CRF collaboration between Neurocrine and GSK has identified multiple unique high affinity and selective antagonists for the CRF1 receptor that are currently in clinical development for mood disorders and irritable bowel syndrome (IBS). There are currently three distinct CRF compounds in clinical development that have arisen out of the GSK collaboration. The compound (876008) is in a Phase II "proof of concept" trial to evaluate its safety and efficacy in patients with IBS. Approximately 130 patients meeting established diagnostic criteria for IBS have been entered into this cross-over design trial. The trial contains standard assessments of safety, tolerability and pharmacokinetics. The clinical endpoints reflect change in symptom frequency and severity and the data should be available later in 2008.

GSK has advanced a novel lead CRF1 receptor antagonist compound, 561679, into a Phase II trial in patients with major depressive disorder. Enrollment of approximately 150 subjects is anticipated in this 6-week randomized, double-blind, placebo-controlled trial.

In addition to the two compounds listed above, GSK has also successfully completed a Phase I single dose-escalating clinical trial with a third CRF1 compound, 586529, for the treatment of anxiety and depression.

Urocortin 2 for Congestive Heart Failure (CHF) Continues Preclinical Evaluation

Initiation of longer term (up to 72 hours in duration) Phase II clinical trials of urocortin 2 are awaiting additional preclinical data. The Company has identified five preclinical studies necessary to support the longer period of infusion in the clinical program. Two of these five preclinical studies were successfully completed by July 2008. The two completed studies were non- GLP toxicology and safety assessment studies over 14 days of continuous infusion in distinct species models. The favorable results of these studies now await confirmation in the GLP preclinical studies anticipated later in 2008.

Indiplon Update

The Company met with the FDA in July for an end of review meeting related to the December 12, 2007 approvable letter for indiplon capsules. The FDA meeting focused on the three additional requirements outlined in the approvable letter. After exchange of correspondence regarding meeting minutes, the Company is awaiting the FDA's final version of these minutes to determine the next course of action related to indiplon capsules.
