Insight on Neurogastrx licensing deal with Daewoong Pharmaceutical to Develop Fexuprazan

Neurogastrx, Inc. has entered into an exclusive license agreement with Daewoong Pharmaceutical Co., Ltd., of Seoul, South Korea, for the development and commercialization of fexuprazan. Fexuprazan is a investigational novel potassium-competitive acid blocker (P-CAB). It is used for the treatment of erosive esophagitis (EE) and other acid-related conditions.

Under the terms of this agreement, Daewoong Pharmaceutical will take a significant equity stake in Neurogastrx, ramping to 13.5% ownership (Daewoong has received a 5 percent equity stake in Neurogastrx as part of the deal and will obtain an additional 8.5 percent share when the firm proceeds with an initial public offering in the future) upon an initial public offering (IPO). Neurogastrx has the exclusive right to develop and commercialize fexuprazan in the U.S. and Canada. Other financial terms of the agreement are not being disclosed.

Under the contract worth $430 million in total, Daewoong will receive milestone payments of undisclosed amounts when stages are completed in the drug’s development process in the US, in addition to royalties based on its future sales in the US and Canada.

Daewoong Pharmaceutical successfully completed a Phase 3 trial with fexuprazan for the treatment of EE in South Korea and will seek marketing approval in that country. Neurogastrx plans to initiate pivotal clinical development for fexuprazan in the U.S. in 2022.
