DUBLIN, May 19, 2014 /PRNewswire/ -- Endo International plc (NASDAQ: ENDP) (TSX: ENL) announced today that affiliates of the company have completed the acquisition of worldwide rights to Sumavel ® DosePro ® (sumatriptan injection), a needle-free delivery system for subcutaneous use, from Zogenix, Inc, for $85 million in cash and rights to additional cash payments based on the achievement of certain commercial milestones. In addition, Endo will assume an existing third party royalty obligation on net sales. The transaction will be financed with Endo's current cash on hand.
Sumavel DosePro is a prescription medicine, given with a needle-free delivery system for the acute treatment of migraine, with or without aura, or cluster headaches in adults. In clinical studies, relief started within 10 minutes for some patients following self-administration, with most achieving relief within 1 or 2 hours. A burst of air delivers sumatriptan just under the skin in less than a second. Sumavel DosePro is designed to be used in just 3 simple steps: SNAP, FLIP, PINCH & PRESS. In a study evaluating ease of use, 51 out of 52 people used Sumavel DosePro correctly the first time with little instruction during a migraine attack.
