TissueTech Receives U.S. Food and Drug Administration Clearance to Proceed with Clinical Study using Investigational New Drug TTBT01

Regenerative medicine research pioneer takes the first step towards commercializing human birth tissue-based biologic products for the treatment of ocular surface disease and disorders

Miami, FL – March 1, 2021BioTissue, Inc., a TissueTech, Inc. company and pioneer in the clinical application of human birth tissue-based products, announced today that its parent company TissueTech had received clearance from the U.S. Food and Drug Administration (FDA) to proceed with a Phase 2 study using morselized Cryopreserved Amniotic Membrane (CAM) and Cryopreserved Umbilical Cord (CUC) Investigational New Drug (IND) TTBT01. This clearance represents another milestone as the company works to achieve FDA approval for its graft and morselized human birth tissue products as biologics for important clinical indications.

Already a leader in ocular clinical research and regenerative medicine, BioTissue is now pioneering a pipeline in ocular biologics, as illustrated by the pursuit of morselized human birth tissue product TTBT01 to support regenerative healing in patients with persistent corneal epithelial defect – commonly referred to as dry eye disease.   As a 351 biologic IND, TTBT01 will be subject to a stringent FDA pre-approval process that includes two randomized Phase 3 clinical trials to demonstrate safety and efficacy.

“We have been diligent in building an infrastructure to develop products as biologics under Section 351 of the Public Health Service Act and pursuing the Biologics License Application (BLA) regulatory pathway for several years now,” said TissueTech Co-Founder, President and Chief Executive Officer, Amy Tseng. “Our leadership team determined early on that going after a regenerative therapy based on natural human birth tissue to achieve Ocular Surface Optimization (OSO) would be the right thing to do – affording the company the opportunity to give physicians optimal treatment options to effectively treat common dry eye problems.”

BioTissue’s commercially available product, Prokera® is well recognized as part of the algorithm in achieving ocular surface optimization, by reducing ocular surface disorder severity and improving dry eye classification from severe frequent/constant to mild and/or episodic.1 Prokera was cleared by the FDA in 2003 as a 510(k) medical device and contains the only amniotic membrane designated by the FDA that has anti-inflammatory, anti-scarring, and anti-angiogenic properties for the ocular surface.
