Zogenix to Present Additional SUMAVEL(R) DosePro(R) Phase 4 Results at Headache Meetings in June


New Data Analyzes Efficacy, Tolerability, and Patient Preference for SUMAVEL DosePro Among Current Triptan Users Requiring a Change in Migraine Therapy

SAN DIEGO, May 27, 2011 (GlobeNewswire via COMTEX) -- Zogenix, Inc. (Nasdaq:ZGNX) today announced that additional data from the Company's Phase 4 clinical study of SUMAVEL(R) DosePro(R) (sumatriptan injection) Needle-free Delivery System will be presented at two upcoming scientific meetings: the American Headache Society(R) 53rd Annual Scientific Meeting (AHS), to be held June 2 -- 5, 2011 in Washington, DC; and the 15th Congress of the International Headache Society (IHS), to be held June 23 -- 26, 2011 in Berlin, Germany.

The Phase 4 open-label, multicenter U.S. study evaluated overall satisfaction, confidence and preference for SUMAVEL DosePro in treating multiple migraine attacks in more than 200 adult patients diagnosed with migraine and currently taking triptan therapy. Efficacy, including onset and sustained duration of pain relief/freedom from pain, and tolerability of therapy with SUMAVEL DosePro were also measured. Data will also be reported from a subset of 90 patients identified by a clinical assessment of current migraine therapy as requiring a change in therapy.

Posters to be presented at these meetings include the following:

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.


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.
