Arena Pharmaceuticals Announces First Quarter 2012 Financial Results and Recent Developments

SAN DIEGO, May 1, 2012 /PRNewswire/ -- Arena Pharmaceuticals, Inc. (NASDAQ: ARNA) today reported financial results for the first quarter ended March 31, 2012, and reviewed recent developments.

"Lorcaserin has the potential to provide a new treatment option for the medical management of obesity," said Jack Lief, Arena's President and Chief Executive Officer. "We are focused on preparing for the May 10 advisory committee meeting for lorcaserin, and look forward to discussing the outcome of the meeting and providing a corporate update following the meeting."

First Quarter 2012 Financial Results

Research and development expenses continued to decline in the first quarter of 2012 to $14.5 million, compared to $15.9 million in the first quarter of 2011. General and administrative expenses in the first quarter of 2012 decreased to $6.4 million, compared to $6.9 million in the first quarter of 2011.

Total interest and other expense decreased to $7.0 million in the first quarter of 2012, compared to $14.7 million in the first quarter of 2011. This decrease is primarily attributable to a reduction of $8.8 million in the non-cash loss on extinguishment of debt recorded in the first quarter of 2012, compared to the first quarter of 2011. Also contributing to the decrease was a $1.7 million reduction in interest expense due to principal prepayments on Arena's Deerfield loan totaling $42.7 million between January 2011 and March 2012. These decreases were partially offset by a $2.8 million increase in non-cash losses from revaluation of derivative liabilities. Arena's net loss allocable to common stockholders in the first quarter of 2012 was $29.4 million, or $0.18 per share, compared to $42.2 million, or $0.35 per share, in the first quarter of 2011.

At March 31, 2012, cash and cash equivalents totaled $88.2 million, which includes net proceeds of $52.6 million from two equity financings in the first quarter of 2012. At March 31, 2012, approximately 180.5 million shares of common stock were outstanding.

About Lorcaserin

Lorcaserin, an investigational drug candidate intended for weight management, including weight loss and maintenance of weight loss, in patients who are obese (BMI >30) or patients who are overweight (BMI >27) and have at least one weight-related co-morbid condition, is a new chemical entity that is believed to act as a selective serotonin 2C receptor agonist. The serotonin 2C receptor is expressed in the brain, including the hypothalamus, an area believed to be involved in the control of appetite and metabolism. Arena has patents that cover lorcaserin in the United States, Europe and other jurisdictions that in most cases are capable of continuing into 2023 without taking into account any patent term extensions or other exclusivity Arena might obtain.

Arena resubmitted the lorcaserin NDA to the FDA in December 2011, and the agency has assigned a new Prescription Drug User Fee Act (PDUFA) target date of June 27, 2012. Eisai Inc. has exclusive rights to market and distribute lorcaserin in the United States subject to FDA approval of the lorcaserin NDA. An MAA for lorcaserin was accepted for filing by the EMA in March 2012. Arena currently owns rights to lorcaserin outside of the United States.
