OptiNose Announces FDA Approval for ONZETRA™ Xsail™ (sumatriptan nasal powder), a New Treatment for Acute Migraine Using Bi-Directional™ Breath Powered® Technology

Product expected to be available in the U.S. in coming months

YARDLEY, PA, January 28, 2016
— OptiNose, a privately-held specialty biopharmaceutical company, today announced that its licensing partner, Avanir Pharmaceuticals, Inc. has reported that the U.S. Food & Drug Administration (FDA) approved ONZETRA™ Xsail™ (sumatriptan nasal powder), formerly AVP-825, for the acute treatment of migraine with or without aura in adults (see Full Prescribing Information and Limitations of Use at www.ONZETRA.com). ONZETRA Xsail is the first product developed by OptiNose to receive FDA approval and is an intranasal medication delivery system using the novel Xsail Breath Powered Delivery Device. The Xsail device is based on OptiNose’s unique and patented Bi-Directional Breath Powered technology platform and delivers a low dose of sumatriptan powder into the nose in a new and different way.


“Our whole team is pleased and excited about this approval and about the opportunity to see migraine patients benefit from using a product based on our Bi-Directional Breath Powered technology platform,” said Ramy Mahmoud, MD, MPH, President of OptiNose.   “This approval highlights the ability of OptiNose to successfully bring differentiated new products that use our innovative technology to the market.  We love the idea of helping people, and our team is working hard to create even more new treatments to do just that.”


“Many patients report that they are not fully satisfied with currently available migraine treatments, and ONZETRA Xsail will provide physicians and patients with a new alternative that offers relief in an innovative way–by using an exhaler,” commented Stephen Silberstein, MD, Neurologist at the Headache Center, Thomas Jefferson University Hospital in Philadelphia, PA, Past President of the American Headache Society and a Principal Investigator in the OptiNose clinical development program for ONZETRA Xsail.  “The design of the Xsail Breath Powered Delivery Device harnesses the patient’s own breath to seal off the nose from the throat and deliver a low dose of a trusted medication to the richly vascular passages deep in the nose.  It’s an alternate approach to treating migraines that is both unique and effective.”


After completing Phase III development, OptiNose out-licensed the North American commercialization and further development rights for ONZETRA Xsail to Avanir Pharmaceuticals, Inc. (a subsidiary of Otsuka America, Inc.). Under the terms of the licensing agreement, OptiNose receives upfront and milestone payments collectively valued at up to $110 million and tiered double digit royalty payments based on net sales.


“In addition to making an important treatment option available to a suffering patient population, the approval of ONZETRA Xsail also provides OptiNose the ability to use the licensing proceeds to help with the research, development, and future commercialization of our next product candidate, OPN-375,” noted Peter Miller, Chief Executive Officer of OptiNose. “If approved, we believe that OPN-375, which is a late phase pipeline asset, may play a valuable role in helping to treat patients for indications associated with chronic nasal inflammatory disease, such as nasal polyposis and chronic sinusitis.  The proceeds will also help us pursue other pipeline assets in 2016.”

About OptiNose Technology: Bi-Directional™ Breath Powered® Drug Delivery Systems


OptiNose’s patented technology for closed-palate Bi-Directional Breath Powered drug delivery systems is unique in that its exhaler devices use the natural functions of a patient’s breath to help effectively and efficiently deliver medications beyond the nasal valve into deep, targeted areas of the nasal cavity. A user exhales into the device, naturally closing the soft palate and sealing off the nasal cavity from the throat. The exhaled breath carries medication from the device into one side of the nose through a specially shaped sealing nosepiece, balancing the pressure on the soft palate. Narrow nasal passages are gently expanded and medication is transported well beyond the nasal valve to targeted sites. After delivering medication to the targeted sites, air flows around to the opposite side of the nasal cavity and exits through the other side of the nose rather than into the throat or lungs.
