Arena Pharmaceuticals Announces First Quarter 2011 Financial Results and Recent Developments

SAN DIEGO, May 10, 2011 /PRNewswire/ -- Arena Pharmaceuticals, Inc. (NASDAQ: ARNA) today reported financial results for the first quarter ended March 31, 2011, and reviewed recent developments.

"In collaboration with Eisai, we are making progress in executing activities to support the submission of our response to the FDA's complete response letter for our lorcaserin new drug application," stated Jack Lief, Arena's President and Chief Executive Officer. "We are also continuing to selectively advance our earlier-stage programs, and we look forward to announcing top-line results from our APD811 Phase 1 trial this quarter."

Research and development expenses continued to decline in the first quarter of 2011 to $15.9 million, compared to $18.3 million in the first quarter of 2010. This decrease is primarily attributable to the workforce reduction Arena initiated in January 2011 and ongoing cost-containment efforts. Arena recorded restructuring charges of $3.5 million related to the workforce reduction in the first quarter of 2011. General and administrative expenses in the first quarter of 2011 totaled $6.9 million, compared to $7.0 million in the first quarter of 2010.

Total interest and other expense increased to $14.7 million in the first quarter of 2011, compared to $6.1 million in the first quarter of 2010. This increase is primarily attributable to a non-cash loss on extinguishment of debt of $10.5 million in the first quarter of 2011 due to Arena's principal prepayments on its Deerfield loan of $20.0 million and $17.7 million in January 2011 and March 2011, respectively. Including the $10.5 million non-cash debt extinguishment charge and $3.5 million of restructuring charges, Arena's net loss allocable to common stockholders in the first quarter of 2011 was $42.2 million, or $0.35 per share, compared to $31.3 million, or $0.33 per share, in the first quarter of 2010.

At March 31, 2011, cash and cash equivalents totaled $119.9 million, and approximately 133.7 million shares of common stock were outstanding.

Arena's Recent Developments


  • Published results from a clinical trial evaluating lorcaserin's abuse potential in the March 16, 2011, issue of Clinical Pharmacology & Therapeutics. The randomized, placebo-controlled, double-blind, crossover trial was conducted in subjects with a history of recreational drug use and compared the relative abuse potential of lorcaserin against three comparators: placebo, 15 and 30 mg of zolpidem (a schedule IV controlled substance) and 100 mg of ketamine (a schedule III controlled substance).
  • Published results from a randomized, placebo-controlled, double-blind mechanism of action study evaluating the contributions of energy intake, appetite and energy expenditure on weight loss with lorcaserin treatment in the March 2011 issue of The Journal of Clinical Endocrinology and Metabolism.


  • Craig M. Audet joined Arena as Vice President, Regulatory Affairs. Mr. Audet has 25 years of experience directing global pharmaceutical and medical device registration and marketed product activities, most recently as Vice President, US Regulatory Affairs, for Sanofi-Aventis. Prior to Sanofi-Aventis, he was Senior Director, Global Therapeutic Area Leader, for Pfizer Inc., where he provided strategic direction and oversight across the cardiovascular/metabolic product portfolio.
  • Completed a US workforce reduction of approximately 25%, or 65 employees, which Arena expects will result in annual operating cost savings of approximately $13.5 million.
  • Received gross proceeds of approximately $35.5 million from the sale of 12,150,000 shares of common stock at $1.46 per share and 12,150 shares of Series C Convertible Preferred Stock at $1,460 per share to certain Deerfield entities. As part of this transaction, Arena prepaid approximately $17.7 million of the loan principal that otherwise would have been required to be repaid to Deerfield in June 2013. Arena also reduced the exercise price from $3.45 to $1.68 per share and extended the end of the exercise term from June 17, 2013, to June 17, 2015, for approximately 14.4 million of the 16.2 million outstanding warrants to purchase common stock that Deerfield received in connection with a June 2010 investment in Arena.
  • Announced the issuance of US Reissue Patent No. RE42,190 with claims to methods of identifying compounds that modulate the activity of the GPR119 receptor, a target for identifying small molecules for the treatment of diabetes.
  • Appointed Mr. Lief as principal financial officer and Jennifer K. Bielasz, Arena's Senior Director, Accounting and Controller, as principal accounting officer upon the departure of Robert E. Hoffman, Arena's former Vice President, Finance and Chief Financial Officer.

Lorcaserin Regulatory Update

In collaboration with Eisai, Arena is engaged in activities to address the issues raised by the US Food and Drug Administration (FDA) in its Complete Response Letter (CRL) and subsequent communications, and following is an update:

  • A pathology working group has completed a blinded reassessment of the mammary tumors found in the rat carcinogenicity study, and the final report is being prepared;
  • Arena expects to initiate preclinical prolactin studies of three months and shorter duration once discussions with the FDA to finalize protocols are complete;
  • Arena and Eisai believe that prolactin studies of three months and shorter duration will be sufficient to test the hypothesis that lorcaserin causes mammary tumors in rats by increasing prolactin effects on the mammary gland, and currently do not anticipate initiating a 12-month study in female rats;
  • To address the finding of brain astrocytoma in male rats, Arena has completed dosing, and analyses are ongoing, of a Phase 1 clinical trial that involved collecting cerebrospinal fluid to provide an alternative means of estimating human brain levels at the intended therapeutic doses of lorcaserin; and
  • Further assessments of receptor pharmacology and abuse liability are ongoing.

Depending on the results of these and other ongoing and planned activities, as well as any new guidance from the FDA, Arena plans to submit its response to the CRL late this year.

Updated 2011 Financial Guidance

In 2011, Arena expects to use cash and cash equivalents of approximately $72 million to $78 million for its operating activities and interest expense, and $2 million for capital expenditures. This does not include $37.7 million in payments on the note payable to Deerfield, which Arena paid in the first quarter of 2011, or $10.1 million on the note payable to Siegfried, of which Arena has paid $3.4 million in the first quarter and the balance will be paid later in 2011. The revised guidance for use of cash and cash equivalents compares to prior guidance of $68 million to $74 million (or, if the $10.1 million payment on the note payable to Siegfried was included, $78 million to $84 million). This increase in use of cash and cash equivalents is due primarily to expenses related to unused manufacturing capacity in Arena's Swiss facility. Assuming no additional capital from collaborators, licensees, investors or other sources, Arena expects to end 2011 with approximately $58 million to $64 million in cash and cash equivalents, compared to Arena's previous guidance of $45 to $51 million. This increase in ending cash reflects net proceeds from a financing transaction with Deerfield.
