YARDLEY, Pa., Sept. 26, 2019 (GLOBE NEWSWIRE) -- OptiNose, Inc. (Optinose) (NASDAQ:OPTN), a pharmaceutical company focused on patients treated by ear, nose and throat (ENT) and allergy specialists, today announced the signing of an agreement between its Norway-based subsidiary OptiNose AS and Currax Pharmaceuticals LLC (Currax) which grants Currax the exclusive rights to certain Optinose intellectual property for the purpose of marketing ONZETRA® XSAIL® (sumatriptan nasal powder) in the United States, Canada, and Mexico.

Additionally, Optinose is eligible to receive a one-time 10% royalty on ONZETRA net sales in excess of $3 million solely for calendar year 2020, and an additional $1 million milestone payment subject to the achievement of a specified regulatory milestone.
