Additional product patent in the US for HyNap-Dasa

Press release 2020-02-12

STOCKHOLM – February 12, 2020. Xspray Pharma (Nasdaq First North Growth Market: XSPRAY) announces that the United States Patent and Trademark Office (USPTO) has granted Xspray a new US patent for HyNap-Dasa. The new patent, US 10,555,937, covers the pharmaceutical composition of the company's primary product candidate, HyNap-Dasa. This is Xspray's fourth product patent in the United States, which is the company's main market. The patent is valid until January 11, 2033.

“This new patent on our most important market is yet another confirmation of our innovative development work. The formal clinical bioequivalence of the company’s primary product candidate HyNap-Dasa, which has been previously communicated, means that the patent further strengthens our position in negotiations with potential partners”, says Per Andersson, CEO of Xspray.

Xspray strives to obtain patents for both composition and technology and this new patent claims an amorphous solid dispersion (pharmaceutical composition) of dasatinib.

“Our strategic patent work will generate additional patents in the United States on our product candidates in the near future. The new HyNap-Dasa patent makes it significantly more difficult for other companies to launch a dasatinib product based on amorphous solid dispersion in the United States during the lifetime of the patent, i.e. up until January 2033”, Per Andersson concludes.

About Xspray Pharma

Xspray Pharma AB (publ) is a product development company with multiple product candidates in clinical development. Xspray uses its innovative, patented RightSize technology to develop improved and generic versions of marketed drugs, primarily protein kinase inhibitors (PKIs) for the treatment of cancer. The segment is the second largest in oncology, and drug prices are very high.

The company´s innovative technology allows Xspray Pharma to gain entry as the first competitor to today’s original drugs before the secondary patents expire. Xspray’s goal is to become the leader in the development of improved drugs or generic versions of PKIs already marketed for the treatment of cancer, which numbered to 54 in December 2019. The company’s leading product candidates, HyNap-Dasa, HyNap-Sora and HyNap-Nilo, are stable amorphous versions of the three blockbuster cancer drugs Sprycel® (dasatinib), Nexavar® (sorafenib) and Tasigna® (nilotinib), respectively. The launch of the first product candidate, HyNap-Dasa, is planned to take place in 2021. The substance patent for the original drug Sprycel® (dasatinib) expires at the end of 2020, and the secondary patents in 2026, which offers Xspray’s HyNap-Dasa a period of five years of semi-exclusivity before other competitors gain access to the market.
