TissueGene, Inc. reported that the U.S. Food and Drug Administration (FDA) accepted the proposed brand name Invossa for TissueGene-C, the Company's proprietary product in development for treatment of osteoarthritis of the knee. FDA's acceptance of the proprietary brand name is subject to the Agency's final determination prior to any approval of the product's Biologic License Application (BLA) and market launch. The United States Adopted Names Council (USAN) of the American Medical Association also approved Tonogenchoncel-L as Invossa's generic name for the U.S. market.

The FDA reviews proposed proprietary names, taking into account potential for confusion between the proposed name and the names of marketed drugs and pending products for which marketing applications are currently under review. The brand name also has been submitted for registration to the U.S. Patent and Trademark Office, the European Union, and 19 additional countries.
