SAN DIEGO, Nov. 10, 2011 (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 third quarter ended September 30, 2011.

Roger Hawley, chief executive officer of Zogenix, stated, "In August, we announced positive pivotal phase 3 efficacy results for our most advanced investigational product candidate, Zohydro. In addition to meeting the primary endpoint of the study, Zohydro demonstrated strong results for several important secondary efficacy endpoints. Combined with our long-term safety study, we believe we are well positioned for our NDA submission. We have a pre-NDA meeting scheduled with the FDA in the fourth quarter and remain on track to submit our NDA for Zohydro by early 2012."

Mr. Hawley added, "SUMAVEL DosePro prescriptions continued to grow in the third quarter. Growth was driven primarily by continued performance of the Zogenix sales force. Our expanded team will enhance our presence with neurologists and high prescribing primary care physicians. Based on weekly prescription data from the first four weeks in October, we believe SUMAVEL DosePro growth in the fourth quarter will accelerate. With two important financings completed, our team is focused on executing our strategic business plan to help migraine patients with unmet medical needs while also building the value of our product pipeline."

Third Quarter 2011 Financial Results

Since launch in early 2010, Zogenix has recognized SUMAVEL DosePro revenue based on product dispensed through patient prescriptions as estimated by Wolters Kluwer Pharma Solutions. Beginning in July 2011, the Company revised its revenue recognition methodology and began to recognize net product revenues upon the shipment of SUMAVEL DosePro to wholesale distributors and retail pharmacies. The Company believes this change in methodology is consistent with other products at this stage of commercialization within the industry.

Total revenues for the third quarter 2011, which consist of net product revenue and contract revenue, were $10.4 million, up 47% from $7.1 million in the third quarter 2010. Net product revenue on sales of SUMAVEL DosePro for the third quarter 2011 was $8.8 million, up 55% from $5.7 million in the third quarter 2010, and up 2% from $8.7 million in the second quarter 2011. Due to the change in the Company's revenue recognition methodology in July 2011, net product revenue was reduced by $1.0 million related to the estimate for potential returned product and partially offset by the recognition of deferred product revenue. Contract revenue for the third quarter 2011 was $1.6 million, reflecting the amortization of license and milestone payments received from Astellas Pharma US, Inc.

Cost of sales for the third quarter 2011 was $5.5 million compared to $2.9 million in the third quarter 2010. Product gross margin was 38% in the third quarter 2011 compared to 49% in the third quarter 2010. The decline in gross margin was primarily driven by excess capacity charges due to lower production volume in order to manage inventory levels. Cost of sales for third quarter of 2011 also includes the recognition of deferred cost of sales related to the change in the Company's revenue recognition methodology.

Royalty expense for the third quarter 2011 was $343,000 compared to $216,000 in the third quarter 2010, reflecting the impact of increased net product revenues.

Research and development expenses for the third quarter 2011 were $10.1 million, up 27% from $8.0 million in the third quarter 2010. The increase in research and development expenses includes a one-time $2.25 million up-front license payment to Durect Corporation made in connection with the execution of the Relday development and license agreement and a $750,000 milestone payment to Alkermes, Inc. made in connection with the completion of the pivotal Phase 3 efficacy trial, Study 801, for Zohydro. These increases were partially offset by a decrease in clinical costs associated with Study 801 which was completed in August 2011.

Selling, general and administrative expenses for the third quarter 2011 were $14.7 million, up 17% from $12.5 million in the third quarter 2010. The increase in selling, general and administrative expenses is primarily due to higher service fees payable to Astellas, expansion of the Zogenix sales force, higher general and administrative costs associated with operating as a public company and higher stock-based compensation charges.

Other expense for the third quarter 2011 was $1.8 million compared to $5.5 million in the third quarter 2010. Other expense for the third quarter 2011 includes the cost of royalty payments and non-cash mark-to-market adjustments for derivatives and warrant liabilities related to the Company's July 2011 royalty and equity financing with Cowen Healthcare Royalty Partners (Cowen Royalty) in addition to interest payments on the Company's debt facilities with Oxford Finance LLC and Silicon Valley Bank.

In the third quarter 2011, the Company closed a royalty and equity financing with Cowen Royalty resulting in aggregate net proceeds of $29.5 million. The Company received $30.0 million from the royalty financing, $10.0 million of which will be repaid each year from 2015 through 2017, and is obligated to make quarterly payments of tiered royalties to Cowen Royalty ranging from 0.5% to 5% based on the Company's revenues. This is reflected as a debt financing arrangement on the Company's balance sheet, net of customary fees and discounts. The royalty payments are reflected as interest expense on the Company's statement of operations and recorded based on an estimated cost of capital in the high-teens. The Company also issued a warrant for 225,000 shares of the Company's common stock at an exercise price of $9 per share for 10 years. In addition, the Company sold 388,601 shares of common stock to Cowen Royalty for total net proceeds of $1.4 million.

Net loss for the third quarter 2011 was $22.0 million, or $0.59 per share, compared to a net loss of $22.1 million, or $16.00 per share, in the third quarter 2010. On a non-GAAP basis, excluding non-cash items outlined in the reconciliation table included in this press release, adjusted net loss for the third quarter 2011 was $20.4 million.

The majority of the Company's outstanding shares in the third quarter of 2010 consisted of preferred stock, which is not included in the weighted average shares outstanding. The weighted average shares outstanding for the third quarter 2011 reflects the conversion of the preferred stock and issuance of common stock in connection with the Company's initial public offering in November 2010, the $1.5 million equity investment by Cowen Royalty closed in July 2011, and the $60.0 million follow-on equity offering closed in September 2011. The weighted average number of shares outstanding during the third quarter 2011 was 37,320,000.

Cash and cash equivalents as of September 30, 2011 were $70.8 million. In October 2011, the Company sold 711,566 shares of common stock to underwriters in connection with the over-allotment of the follow-on equity offering which resulted in net proceeds of $1.3 million.

Ann Rhoads, chief financial officer of Zogenix, commented, "During the third quarter we closed on two significant financings and ended the quarter with approximately $71 million in cash. This puts us in an excellent position to continue to drive sales of SUMAVEL DosePro while also advancing our Zohydro program through approval and preparing to file an IND for Relday."

2011 Full Year Financial Guidance

The Company is updating its revenue and gross margin guidance for the year to reflect the transition to the Company's revised revenue recognition methodology.

      contract revenues, under the revised methodology (previously anticipated
      range was $43 million to $47 million)

  --  Research and development expenses are expected to be $34 million to $36
      million (previously anticipated range was $37 million to $39 million)

About SUMAVEL DosePro

SUMAVEL DosePro (sumatriptan injection) is indicated for the acute treatment of migraine attacks, with or without aura, and the acute treatment of cluster headache episodes.

SUMAVEL DosePro should only be used where a clear diagnosis of migraine or cluster headache has been established. SUMAVEL DosePro is not intended for the prophylactic therapy of migraine or for use in the management of hemiplegic or basilar migraine and should not be administered intravenously. For a given attack, if a patient does not respond to the first dose of SUMAVEL DosePro, the diagnosis of migraine or cluster headache should be reconsidered before administration of a second dose.

Important Safety Information

SUMAVEL DosePro is contraindicated in patients with uncontrolled hypertension, in patients with history, symptoms or signs of ischemic heart disease, coronary artery vasospasm, cerebrovascular or peripheral vascular disease including ischemic bowel disease and in patients with other significant underlying cardiovascular diseases or known hypersensitivity to sumatriptan. SUMAVEL DosePro should not be given to patients in whom unrecognized coronary artery disease is predicted by the presence of risk factors without a prior cardiovascular evaluation.

Serious cardiovascular events, including death, have been reported when taking sumatriptan, including patients with no findings of cardiovascular disease. Considering the extent of use of sumatriptan in patients with migraine, the incidence of these events is extremely low. Cerebrovascular events, some fatal, have been reported in patients treated with sumatriptan. In a number of cases, it appears possible that the cerebrovascular events were primary, sumatriptan having been administered in the incorrect belief the symptoms experienced were a consequence of migraine when they were not. It is important to advise patients not to administer SUMAVEL DosePro if a headache being experienced is atypical.

Do not use SUMAVEL DosePro and any ergotamine-containing or ergot-type medication within 24 hours of each other; do not use SUMAVEL DosePro and another 5-HT1 agonist (e.g. triptan) within 24 hours of each other (with the exception of a single dose of another sumatriptan product, provided the doses are separated by at least 1 hour). SUMAVEL DosePro is not generally recommended for use with MAO-A inhibitors. The development of a potentially life-threatening serotonin syndrome may occur with triptans, including treatment with SUMAVEL DosePro, particularly during combined use with selective serotonin reuptake inhibitors (SSRIs) and serotonin-norepinephrine reuptake inhibitors (SNRIs). SUMAVEL DosePro should be used during pregnancy only if the potential benefit justifies the potential risk.

In controlled clinical trials with sumatriptan injection, the most common adverse reactions were injection site reactions, tingling, warm/hot sensation, burning sensation, feeling of heaviness, pressure sensation, feeling of tightness, numbness, feeling strange, tight feeling in head, flushing, tightness in chest, discomfort in nasal cavity/sinuses, jaw discomfort, dizziness/vertigo, drowsiness/sedation and headache.
