SAN DIEGO--Zogenix, Inc. (Nasdaq:ZGNX), a pharmaceutical company developing and commercializing products for the treatment of central nervous system disorders and pain, and Mallinckrodt (NYSE:MNK) announced today that the co-promotion of SUMAVEL® DosePro® (sumatriptan injection) Needle-free Delivery System will end on January 31, 2014.

SUMAVEL DosePro is Zogenix's first commercial product and was launched in January 2010 for the acute treatment of migraine and cluster headache.  

Beginning February 1, 2014, Zogenix will assume full responsibility for the continued commercialization of the brand, with a focus on headache specialists, pain specialists and neurologists who treat a significant number of migraine patients. The early termination of the co-promotion by five months, originally scheduled to end on June 30, 2014, is timed to precede the previously disclosed expansion of the Zogenix sales force planned in February 2014. 

The companies have agreed to a detailed customer transition plan with a goal of uninterrupted access and

service to prescribers of SUMAVEL DosePro.

Under the amended co-promotion agreement, neither company will incur any penalty payments related to the early termination of the agreement which was originally slated to expire June 30, 2014. Mallinckrodt will continue to earn a service fee based on product sales to its physician segment through January 31, 2014. Zogenix will no longer pay service fees to Mallinckrodt for sales of SUMAVEL DosePro beginning February 1, 2014.

the acute treatment of cluster headache in adults. 

Limitations of Use

SUMAVEL DosePro is intended for use only if a clear diagnosis of migraine or cluster headache has been established. If a patient has no response to the first migraine attack treated with SUMAVEL DosePro, reconsider the diagnosis of migraine before SUMAVEL DosePro is administered to treat any subsequent attacks. SUMAVEL DosePro is not indicated for the prevention of migraine attacks.

Dosage and

Administration

The maximum single recommended dose of Sumavel DosePro for the acute treatment of migraine or cluster headache is 6 mg given subcutaneously. SUMAVEL DosePro is intended for subcutaneous use only. SUMAVEL DosePro is intended for use as an acute treatment of migraine or an acute treatment of cluster headache. For the treatment of cluster headache, the efficacy of a lower dose has not been established. The maximum cumulative dose of SUMAVEL DosePro in a 24-hour period is 12 mg, with doses separated by at least 1 hour. SUMAVEL DosePro is intended to be administered only to the abdomen or thigh.

IMPORTANT SAFETY INFORMATION

SUMAVEL DosePro is contraindicated in patients with ischemic coronary artery disease (CAD) (angina pectoris, history of myocardial infarction, or documented silent ischemia) or coronary artery vasospasm, including Prinzmetal's angina; Wolff-Parkinson-White syndrome or arrhythmias associated with other cardiac accessory conduction pathway disorders; history of stroke or transient ischemic attack (TIA); hemiplegic or basilar migraine; peripheral vascular disease; ischemic bowel disease; uncontrolled hypertension; recent (within 24 hours) use of another 5-HT1 agonist (e.g., another triptan) or of an ergotamine-containing medication; current or recent (past 2 weeks) use of monoamine oxidase-A inhibitor; and known hypersensitivity to sumatriptan.

There have been rare reports of serious cardiac adverse reactions, including acute myocardial infarction, occurring within a few hours following administration of SUMAVEL DosePro. Some of these reactions occurred in patients with no known CAD. SUMAVEL DosePro may cause coronary artery vasospasm (Prinzmetal's angina), even in patients without a history of CAD. 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.

Warnings and Precautions

Discontinue use of SUMAVEL DosePro if the following occur: arrhythmias; cerebral hemorrhage, subarachnoid hemorrhage, and stroke; gastrointestinal ischemia and infarction events, peripheral vasospastic reactions; serotonin syndrome; and/or anaphylactic/anaphylactoid reactions. Perform cardiac evaluation in patients with multiple cardiovascular risk factors, including myocardial ischemia/infarction and Prinzmetal's angina. While generally not associated with myocardial ischemia; evaluate for CAD in patients at high risk with the following symptoms: chest/throat/neck/jaw pain, tightness, pressure, or heaviness. In the event of a headache associated with medication overuse, detoxification may be necessary. In the event of an increase in blood pressure, monitor blood pressure. Use with caution in patients with epilepsy or a lowered seizure threshold.

Adverse Reactions

In controlled clinical trials with sumatriptan injection, the most common adverse reactions were injection site reactions, tingling, dizziness/vertigo, warm/hot sensation, burning sensation, feeling of heaviness, pressure sensation, flushing, feeling of tightness, and numbness.
