Cohera Medical, Inc.® submits PMA Supplement to expand indications for TissuGlu® Surgical Adhesive

RALEIGH, N.C., March 01, 2018 (GLOBE NEWSWIRE) -- Cohera Medical, Inc., a leading innovator and developer of absorbable surgical adhesives and sealants, announced today that it has submitted a Premarket Approval Application (PMA) supplement to the U.S. Food and Drug Administration (FDA) for its TissuGlu Surgical Adhesive.  The supplement contains new clinical evidence supporting a review by the FDA to expand the indication for TissuGlu in the United States.

TissuGlu is currently approved in the U.S. for the approximation of tissue layers where subcutaneous dead space exists between tissue planes in abdominoplasty.  TissuGlu Surgical Adhesive was the first 100% synthetic internal surgical adhesive approved for sale in the United States.

The Company recently completed multiple favorable clinical studies and compiled its real-world evidence collected in over six years of use outside the U.S. to support the application of expanded indication to use TissuGlu in all large tissue flap surgeries.

“The submission of the PMA supplement to expand the U.S. indications of TissuGlu is a significant milestone for the Company,” said Patrick Daly, Cohera Medical President and Chief Executive Officer for Cohera. “We are excited about the potential to make TissuGlu available to more surgeons and patients in the United States.”

TissuGlu is designed to meet a surgeon’s need for a strong, biocompatible, and easy-to-use surgical adhesive. The primary evidence included in the supplement application consists of data from a multi-center, prospective clinical trial comparing the use of TissuGlu to the standard of care in mastectomy procedures.  The results of this study concluded that TissuGlu is a safe and effective alternative to the use of postoperative fluid collection drains in mastectomy surgeries. This evidence is combined with recent clinical studies in DIEP flap and decubitus pressure sore flap procedures.

“This PMA supplement for TissuGlu culminates several years of work by the company, its clinical partners, and customers,” said Chad Coberly, JD, Chief Clinical & Legal Officer for Cohera.  “The company looks forward to working with the FDA and its review team during the review of this important application.” 

TissuGlu is targeted for use in large flap procedures where elimination of deadspace created between the tissue layers is beneficial to facilitate natural healing of the tissues.  The product has been on the market in the EU since 2011, and currently more than 5,000 procedures have been conducted with TissuGlu bringing great benefit to patients, surgeons, and caregivers.
