KemPharm and twoXAR Announce Technology Collaboration to Develop Prodrug-Based Therapies for Multiple Indications

Drug Development Approach Combines twoXAR’s Artificial-Intelligence-Driven Drug Discovery Technology with KemPharm’s LATTM Prodrug Technology

Coralville, IA and Mountain View, CA – October 23, 2018 –KemPharm, Inc. (NASDAQ: KMPH), a clinical-stage specialty pharmaceutical company focused on the discovery and development of proprietary prodrugs, and twoXAR, Inc., an artificial-intelligence (AI)-driven biopharmaceutical company, together announced todaythat they have entered into a technology collaboration to develop prodrug-based therapies for multiple therapeutic areas and indications.  This collaboration will combine twoXAR’s AI-based technology to identify and de-risk drug product candidates with KemPharm’s LATTM technology developed to create new prodrugs that are designed to address unmet patient needs, improve the profile of drug product candidates and generate long-lived composition-of-matter patents.

In connection with this collaboration, KemPharm has executed a research and license agreement with Novoxar, Inc. a wholly-owned subsidiary of twoXAR, under which KemPharm will begin research to develop a prodrug that may form the basis of a target drug product candidate of Novoxar in a therapeutic area which has yet to be disclosed. Under this agreement, KemPharm is eligible to receive specified license fees upon successful delivery of the target prodrug, payments upon achievement of certain product development and commercial milestones, and royalties on commercial sales of any product developed under this agreement.

“Today’s announcement of a technology collaboration between twoXAR and KemPharm, and the related research and license agreement with Novoxar, provide KemPharm’s team with another opportunity to apply our prodrug expertise to a potentially under-served therapeutic area, and ultimately bring potential new benefits to patients,” said Travis C. Mickle, Ph.D., President and Chief Executive Officer of KemPharm.  “We believe this collaboration has the potential to create long-term value for our shareholders by potentially extending KemPharm’s reach into new therapeutic areas, creating long-term patent protection and, together with twoXAR, further de-risk and accelerate the product development cycle.”

“KemPharm’s LATTM technology provides a path to creating unique and valuable drug candidates,” said Andrew A. Radin, Co-Founder and CEO of twoXAR. “The KemPharm team’s technology and drug development experience combined with twoXAR’s discovery technology enables a route to greater efficiency in drug development.”
