Arena Pharmaceuticals Announces Second Quarter 2008 Financial Results and Recent and Second Quarter Highlights

SAN DIEGO, Aug 05, 2008 /PRNewswire-FirstCall via COMTEX News Network/ -- Arena Pharmaceuticals, Inc. (Nasdaq: ARNA) today reported financial results for the second quarter ended June 30, 2008.

Total revenues in the second quarter of 2008 were $2.6 million, compared to $4.8 million in the second quarter of 2007, and included $2.0 million in revenue under Arena's contract manufacturing agreement with Siegfried Ltd and $0.6 million in patent reimbursements from Arena's collaborations with Merck & Co., Inc. and Ortho-McNeil Pharmaceutical, Inc. Total revenues in the first half of 2008 were $5.3 million, compared to $9.7 million in the first half of 2007. Arena reported a net loss allocable to common stockholders in the second quarter of 2008 of $65.8 million, or $0.89 per share, and a net loss allocable to common stockholders in the first half of 2008 of $120.8 million, or $1.64 per share. This compares with a net loss allocable to common stockholders in the second quarter of 2007 of $39.1 million, or $0.64 per share, and a net loss allocable to common stockholders in the first half of 2007 of $71.5 million, or $1.18 per share.

"Our commitment to generating a robust lorcaserin NDA, as part of our larger plan for discovering and developing innovative therapies, is capital intensive. However, we believe this helps increase our opportunities for success and improve returns for investors that share our mission to develop the best innovative therapies," stated Jack Lief, Arena's President and Chief Executive Officer. "We are well-positioned to continue to build on our accomplishments and achieve key milestones, including results from our pivotal BLOOM obesity trial, results from our APD125 Phase 2b insomnia trial and the advancement of our pipeline as we explore licensing opportunities for our programs."

Research and development expenses totaled $56.4 million in the second quarter of 2008, compared to $40.9 million in the second quarter of 2007. Research and development expenses in the first half of 2008 totaled $104.0 million, compared to $76.6 million in the first half of 2007. This increase in research and development expenses is primarily attributable to increased clinical trial costs related to the Phase 3 clinical program for lorcaserin hydrochloride, Arena's drug candidate for the treatment of obesity, and the APD125 Phase 2b trial for the treatment of insomnia. Research and development expenses in the first half of 2008 included $2.2 million in non-cash, share-based compensation expense, compared to $2.1 million in the first half of 2007. General and administrative expenses totaled $7.2 million in the second quarter of 2008, compared to $6.8 million in the second quarter of 2007. General and administrative expenses in the first half of 2008 totaled $16.0 million, compared to $11.8 million in the first half of 2007. This increase in general and administrative expenses is primarily attributable to increases in personnel-related expenses and patent costs. Total patent costs, including patent costs related to partnered programs, increased by $1.1 million in the first half of 2008 compared to the first half of 2007, while total personnel-related expenses increased by $1.4 million between these same periods. General and administrative expenses in the first half of 2008 included $2.1 million in non-cash, share-based compensation expense, compared to $2.0 million in the first half of 2007.

Interest and other income and expenses, net, in the second quarter and first half of 2008 included a $2.0 million non-cash charge as a reserve for a contingent liability for the possible settlement of a disagreement with one of Arena's two warrant holders from its series B redeemable convertible preferred stock financing. Arena previously settled in June 2006 a similar disagreement with the other warrant holder.

Cash, cash equivalents and short-term investments totaled $272.2 million at June 30, 2008. Approximately 73.9 million shares of common stock were outstanding at June 30, 2008.

Arena's Recent and Second Quarter Highlights

-- Completed BLOSSOM enrollment with 4,008 obese and overweight patients in about 95 clinical sites in the United States. BLOSSOM is a one-year, randomized, double-blind, placebo-controlled clinical trial. BLOSSOM and BLOOM comprise Arena's pivotal trial program evaluating lorcaserin's safety and efficacy for the treatment of obesity.

-- Reported positive Phase 1b clinical trial results of APD791, Arena's internally discovered oral drug candidate intended for the treatment of arterial thrombosis and other related conditions. This Phase 1b trial was a randomized, double-blind, placebo-controlled multiple-ascending dose trial in 50 healthy volunteers.

-- Dr. Thomas Roth of Henry Ford Hospital presented data from Arena's positive Phase 2a clinical trial of APD125 for the treatment of insomnia in an oral presentation at the SLEEP 2008 22nd Annual Meeting of the Associated Professional Sleep Societies. When compared to placebo, APD125 significantly improved endpoints measuring improvements in sleep maintenance without any next day impairment of cognition or coordination.

-- Initiated a Phase 2b clinical trial of APD125, Arena's internally discovered oral drug candidate intended to reduce insomnia symptoms and improve sleep maintenance and quality. This is a randomized, double-blind, placebo-controlled subjective study that is expected to enroll approximately 675 patients in about 65 clinical sites in the United States.

-- Taisho Pharmaceutical Co., Ltd. initiated a Phase 1 clinical trial of a drug candidate under a GPCR-focused partnership to develop compounds to treat psychiatric disorders. The drug candidate is a novel oral compound intended for the treatment of an undisclosed, common psychiatric disorder.

Updated 2008 Financial Guidance

Arena also reported that it updated its financial guidance for 2008 expenses for external clinical and preclinical study fees and expenses to approximately $130 to $138 million from $114 to $124 million. The change is primarily due to consolidating the lorcaserin pivotal trial program into two trials, BLOOM and BLOSSOM, while maintaining the same number of patients, approximately 7,000, originally planned across a three trial pivotal program. The entire Phase 3 program includes BLOOM, BLOSSOM and a non-pivotal Phase 3 trial, BLOOM-DM, which is expected to enroll approximately 600 patients. The increase is partially offset by reductions in expenses in the other development programs. Due to savings in other areas, including capital expenditures, as well as changes in the company's balance sheet, including an increase in accrued clinical expenses at the end of 2008 as compared to the beginning of 2008, Arena still expects to end 2008 with approximately $160 million in cash, cash equivalents and short-term investments, which assumes that common stock will be issued in connection with the conversion or redemption of outstanding shares of its series B redeemable convertible preferred stock, including any that may be redeemed on the series B-1's December 2008 mandatory redemption date. If Arena partners any of its programs, it would expect that its year-end cash, cash equivalents and short- term investments would be higher.
