VANCOUVER, BC and UTTENWEILER, GERMANY / ACCESSWIRE / October 18, 2022 / XPhyto Therapeutics Corp. (CSE:XPHY)(OTCQB:XPHYF)( FSE:4XT) ("XPhyto" or the "Company") is pleased to report the results of its Rotigotine transdermal ("TDS") patch human skin cadaver study and dissolution data. The Company's Rotigotine patch is based on the TDS platform technology developed by its wholly owned German subsidiary, Vektor Pharma TF GmbH ("Vektor").

Further to the Company's product update on October 11, 2022, XPhyto is pleased to report excellent results from its recent Rotigotine TDS human cadaver skin absorption study. The study compared drug absorption between XPhyto's optimized new formula and the name brand product in three separate samples over a 24-hour period in accordance with EMA's Guideline on quality of transdermal patches.

The study results demonstrate exceptionally similar dissolution and absorption profiles between XPhyto's drug formulation and the name brand product ("NB"):

"As our lead product we are extremely pleased with these results. They have exceeded our expectations," said Hugh Rogers, XPhyto CEO & Director. "We are confident that our Rotigotine patch is fully optimized and ready for further human clinical evaluation. This is a major milestone in the pathway to product commercialization."

Rotigotine is a non-ergoline dopamine agonist approved for the treatment of Parkinson's disease and restless legs syndrome (RLS) in Europe and the United States. The active pharmaceutical ingredient is not well absorbed via oral delivery and is formulated as a once-daily TDS patch to increase bioavailability and provide a slow and steady supply of the drug over the course of 24 hours. The therapeutic market for Parkinson's disease is over 10 million people worldwide and growing. The top selling name brand product launched by the originator in 2007 independently sold over $375 million of its Rotigotine TDS patches in 2021. According to Wissen Market Research, total global sales for Rotigotine patches were approximately US$518 million in 2021 with the market expected to surpass US$766 million by 2030.

XPhyto's Rotigotine transdermal product is a single product based on its 100% owned platform technology which represents a scalable opportunity for additional TDS drug development and manufacturing programs. According to Research and Markets, the global transdermal skin patch market had a value of nearly US$6.5 billion in 2020 while Kuick Research, Pharmaceutical and Healthcare, estimate the market will reach approximately US$20 billion by 2028.
