SAN DIEGO, May 14, 2012 (GLOBE NEWSWIRE) -- Zogenix, Inc. (Nasdaq:ZGNX), a pharmaceutical company commercializing and developing products for the treatment of central nervous system disorders and pain, today reported financial results for the first quarter ended March 31, 2012.

Roger Hawley, chief executive officer of Zogenix, stated, "During the first quarter, we continued to achieve growth in SUMAVEL DosePro product sales and prescriptions. We also successfully executed our transition plan with Astellas, with our sales force now responsible for detailing the specialist and primary care segments as of April 1st. Our initial experience in the transition of primary care has been encouraging. We fully expect to capitalize on this market segment as we continue to actively engage with potential co-promotion partners."

Stephen J. Farr, Ph.D., president and chief operating officer of Zogenix, said, "We made considerable progress on our research and development programs. On May 1st, we achieved the significant milestone of submitting our NDA for Zohydro to the FDA. The submission was in-line with our timing expectations and puts Zohydro on track to potentially gain approval in the first half of 2013. In addition, we are in final preparations for submitting our Investigational New Drug (IND) application for our second DosePro product candidate, Relday(TM), within the next 30 days. Furthermore, our efforts with Battelle to launch their DosePro marketing campaign this quarter are rapidly progressing, providing the opportunity to continue to enhance the value of Zogenix through new product partnerships and technology out-licensing agreements."

First Quarter 2012 Financial Results

Total revenues for the first quarter 2012, which consist of net product revenue and contract revenue, were $18.3 million, up 103% from $9.0 million in the first quarter 2011. Net product revenue on sales of SUMAVEL DosePro for the first quarter 2012 was $9.9 million, up 32% from $7.5 million in the first quarter 2011. This increase was driven primarily by higher unit volume. Contract revenue for the first quarter 2012 was $8.5 million, reflecting the accelerated amortization of license and milestone payments received from Astellas based on the earlier termination date of the co-promotion agreement. This compares to contract revenue of $1.6 million in the first quarter of 2011. As a result of the termination of the co-promotion agreement with Astellas, no further contract revenue will be recognized related to this agreement.

Cost of sales for the first quarter 2012 was $5.1 million, compared to $4.9 million in the first quarter 2011. Product gross margin was 49% in the first quarter 2012, compared to 35% in the first quarter 2011. The improvement in gross margin was driven primarily by increased net product revenue for the quarter and a decrease in charges for underutilized capacity.

Royalty expense for the first quarter 2012 was $357,000, compared to $297,000 in the first quarter 2011, reflecting the impact of increased net product revenue.

Research and development expenses for the first quarter 2012 were $6.0 million, representing a 30% decrease from $8.5 million in the first quarter 2011. The decrease in research and development expenses was the result of lower clinical costs associated with the Company's Phase 3 clinical trials, which were completed in 2011.

Selling, general and administrative expenses for the first quarter 2012 were $14.6 million, compared to $12.9 million in the first quarter 2011. The 14% increase in selling, general and administrative expenses was due primarily to expansion of the Zogenix sales force completed in the fourth quarter 2011, higher sampling costs, higher service fees to Astellas, and higher stock-based compensation charges.

Other expenses for the first quarter 2012 were $2.6 million, which included the cost of interest expense on our debt obligations with Oxford and Silicon Valley Bank, as well as royalty payments and non-cash mark-to-market adjustments for derivatives and warrant liabilities related to the Company's July 2011 royalty financing and equity investment agreement with Cowen Healthcare Royalty Partners. The Company records interest expense on the Cowen debt obligation on an effective interest method at a rate in the mid-to-high teens, while actual quarterly royalty payments are made at a rate of 5% of net product revenues historically, increasing to 5.75% of net product revenues in April 2012.

Net loss for the first quarter 2012 was $10.3 million, or $0.16 per share, compared to a net loss of $19.0 million, or $0.56 per share, for the first quarter 2011.

The weighted average shares outstanding were 65,369,000 for the first quarter 2012.

Cash and cash equivalents as of March 31, 2012, were $39.8 million.
