CollPlant Files U.S. Patent Application for

Next Generation Dermal Filler

Ness Ziona, May 8, 2018, CollPlant (NASDAQ:CLGN , TASE: CLPT), a regenerative medicine company utilizing its proprietary plant-based rhCollagen technology for tissue repair products (recombinant human, “rhCollagen”), announced that it has filed a provisional patent application with the U.S. Patent and Trademark Office (USPTO) for photocurable dermal fillers comprised of rhCollagen and hyaluronic acid, for the aesthetics market.

Yehiel Tal, CollPlant’s Chief Executive Officer, noted, “This application to the USPTO represents an integral part of the Company's strategy to expand the uses for its novel, rhCollagen-based BioInk into new, high value markets. The combination of hyaluronic acid, a naturally-occurring, moisture-binding compound, with CollPlant’s plant-based, tissue regenerating rhCollagen, is intended to form the basis for a new dermal filler product line aimed at addressing the need for ‘healthier,’ more innovative aesthetic products to treat wrinkles. Utilization of photocuring technology is expected to simplify the filler administration process and enable an even more effective treatment.”
