The 2010 CONNECT MIP Awards recognize the emerging technologies and cutting-edge products that drive San Diego’s innovation economy. SUMAVEL DosePro received top honors as the most innovative product for 2010 in the Life Sciences – Medical Products category.

SUMAVEL DosePro offers fast-acting, easy-to-use, needle-free subcutaneous administration of sumatriptan for patients suffering from migraine attacks, and has demonstrated consistent monthly growth in total prescriptions since its U.S. commercial launch in January 2010. It is the first drug product approved by the U.S. Food and Drug Administration (FDA) which allows for the needle-free, subcutaneous delivery of medication.

Roger L. Hawley, Chief Executive Officer and Director of Zogenix said, “We are honored that CONNECT has recognized SUMAVEL DosePro, and by extension our proprietary DosePro delivery system, as a significant innovation. San Diego is a rich source of new and exciting technologies, and we are proud to be distinguished in the region as the most innovative medical product within the life sciences category.”

SUMAVEL DosePro is currently approved in the United States and Denmark for the acute treatment of migraine attacks, with or without aura, and the acute treatment of cluster headache. SUMAVEL DosePro may offer a fast-acting and efficacious treatment alternative to oral and nasal triptans with simple, convenient administration when compared to traditional, needle-based sumatriptan injection. These unique attributes may be ideally suited for challenging migraine attacks, such as morning migraines, fast onset migraine and migraines with vomiting.

Zogenix and its co-promotion partner, Astellas Pharma US, Inc., launched SUMAVEL DosePro in the United States in January 2010. Zogenix has a partnership with Desitin Arzneimittel GmbH to develop and commercialize SUMAVEL DosePro in the European Union. Desitin plans to launch SUMAVEL DosePro in Denmark in early 2011.

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. For more information about SUMAVEL DosePro, please visit www.SUMAVELDosePro.com.

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.

SUMAVEL DosePro should not be used within 24 hours of other ergotamine-containing or ergot-type medications or other 5-HT1 agonists and 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.

Zogenix is concurrently conducting a pivotal Phase 3 efficacy study (Study 801) of ZX002. Study 801 is a randomized, 12-week, double-blind, placebo-controlled trial that is continuing to enroll opioid-experienced adult subjects with moderate to severe chronic lower back pain. The primary efficacy endpoint is the mean change in average daily pain intensity scores between ZX002 and placebo. Study 801 is expected to be fully enrolled in early 2011. Initial top-line data from Study 801 are also anticipated in the second half of 2011.

Pending positive Phase 3 clinical results, Zogenix expects to submit an NDA for ZX002 with U.S. Food and Drug Administration (FDA) by early 2012. If approved, ZX002 has the potential to be the first controlled-release version of hydrocodone and also the first hydrocodone product that is not combined with another analgesic.

Stephen J. Farr, Ph.D., President and Chief Operating Officer said, “With the completion of enrollment in our Phase 3 safety study, we believe ZX002 is on track to be the first potential single-entity, controlled-release hydrocodone formulation. Most marketed hydrocodone products contain acetaminophen, an analgesic which can cause liver toxicity at high doses over time. ZX002 is not combined with any other analgesic, and may be suitable for both patients who are using immediate-release opioid products on a chronic basis and patients already using extended-release opioids.”

The American Pain Society estimated in 1999 that 9% of the U.S. adult population suffers from moderate to severe non-cancer related chronic pain. Chronic pain can be treated with both immediate-release and extended-release opioids. Marketed hydrocodone products are the most commonly prescribed pharmaceuticals in the United States, generating $3.1 billion in U.S. sales during the 12 months ended June 2010 (Wolters Kluwer Pharma Solutions, Source®: PHAST Retail). Most of these products contain the analgesic combination ingredient acetaminophen. When used in high dosages over time, acetaminophen can cause liver toxicity.

About ZX002
ZX002 is a novel, oral, single-entity controlled-release formulation of hydrocodone currently in Phase 3 clinical trials for the treatment of moderate to severe chronic pain in patients requiring around-the-clock opioid therapy for an extended period of time. ZX002 uses Elan Pharma International Limited’s proprietary Spheroidal Oral Drug Absorption System, or SODAS® Technology. The SODAS technology serves to enhance the release profile of hydrocodone to provide consistent 12-hour pain relief relative to existing immediate-release combination formulations.

If approved, ZX002 may represent the first available controlled-release version of hydrocodone and also the first hydrocodone product that is not combined with another analgesic. The Phase 3 clinical development program for ZX002 was initiated in March 2010 and initial top-line data are anticipated in the second half of 2011. Pending positive Phase 3 clinical results, Zogenix expects to submit a new drug application (NDA) for ZX002 with U.S. Food and Drug Administration (FDA) by early 2012.
