Arena Pharmaceuticals, Inc. Announces Fourth Quarter and Full Year 2008 Financial Results

SAN DIEGO, March 12, 2009 /PRNewswire-FirstCall/ -- Arena Pharmaceuticals, Inc. today reported financial results for the fourth quarter and full year ended December 31, 2008.

Arena reported a net loss allocable to common stockholders in the fourth quarter of 2008 of $62.5 million, or $0.84 per share, and a net loss allocable to common stockholders in the full year ended December 31, 2008 of $239.5 million, or $3.24 per share. This compares with a net loss allocable to common stockholders in the fourth quarter of 2007 of $40.9 million, or $0.60 per share, and a net loss allocable to common stockholders in the full year ended December 31, 2007 of $145.3 million, or $2.31 per share. The increased net loss in 2008 over 2007 is due primarily to Arena’s Phase 3 clinical trial program of lorcaserin hydrochloride, or lorcaserin, for the treatment of obesity. Total revenues in the fourth quarter of 2008 were $2.7 million, compared to $4.6 million in the fourth quarter of 2007. Total revenues in the full year ended December 31, 2008 were $9.8 million, compared to $19.3 million in the full year ended December 31, 2007. This revenue decrease in 2008 is due primarily to reaching the end of the research funding portion of Arena’s collaborations with Merck & Co., Inc., and Ortho-McNeil-Janssen Pharmaceuticals, Inc., in the fourth quarter of 2007.

“We are excited that in only a few weeks we will be announcing top-line data from the first of two pivotal trials evaluating the safety and efficacy of lorcaserin, which has the potential to be the first in a new class of drugs selectively targeting a well validated weight loss receptor,” stated Jack Lief, Arena’s President and Chief Executive Officer. “Given the challenging economic environment, we will continue to focus our resources on the lorcaserin program. I am optimistic that data from this program, as well as from other programs in our broad pipeline, will continue to generate interest from prospective collaborators and help in our efforts to strengthen our balance sheet.”

Research and development expenses totaled $53.3 million in the fourth quarter of 2008, compared to $40.7 million in the fourth quarter of 2007. Research and development expenses totaled $204.4 million in the full year ended December 31, 2008, compared to $149.5 million in the full year ended December 31, 2007. This increase in research and development expenses in 2008 over 2007 is primarily attributable to the Phase 3 program of lorcaserin. Research and development expenses for all of 2008 included $5.0 million in non-cash, share-based compensation expense, compared to $4.2 million in 2007. General and administrative expenses totaled $8.6 million in the fourth quarter of 2008, compared to $6.9 million in the fourth quarter of 2007. General and administrative expenses totaled $30.5 million in the full year ended December 31, 2008, compared to $26.6 million in the full year ended December 31, 2007. This increase in general and administrative expenses in 2008 over 2007 is primarily attributable to increases in personnel-related expenses, as well as costs related to managing Arena’s growing and maturing patent portfolio. General and administrative expenses in 2008 included $3.5 million in non-cash, share-based compensation expense, compared to $4.6 million in 2007. Total patent costs, including patent costs related to partnered programs, were $7.3 million in the full year ended December 31, 2008, compared to $6.4 million in the full year ended December 31, 2007.

Total interest and other income in 2008 reflected a net expense due to a decrease in interest income, as well as non-cash charges related to a settlement with one of Arena’s two warrant holders from its Series B Convertible Preferred Stock financing and a write-down of an investment in TaiGen Biotechnology Co., Ltd. Arena redeemed all of its outstanding shares of Series B Convertible Preferred Stock in November 2008 for $55.8 million.

Cash, cash equivalents and short-term investments totaled $110.1 million at December 31, 2008. Approximately 74.1 million shares of Arena’s common stock were outstanding at December 31, 2008.
