Multiple Postmarket Clinical Studies Nearing Completion In Europe, Supporting Broad Range Of Applications For TissuGlu® Surgical Adhesive

Cohera Medical, Inc.® is completing clinical series in Germany, Switzerland, Netherlands, and the United Kingdom for surgical indications including drain-free mastectomy, DIEP, decubitus, and large open ventral hernia repair.

Raleigh, N.C (GLOBE NEWSWIRE) - Six postmarket clinical series studying outcomes associated with the use of TissuGlu Surgical Adhesive in a variety of surgical procedures are nearing completion in Europe. The studies, involving over 200 patients in four European countries, all evaluate TissuGlu in surgical procedures adhering a skin flap to the underlying tissue to minimize dead space and facilitate the healing process. In some procedures, the use of postsurgical drains to manage fluid during recovery were eliminated. These studies will expand the growing body of evidence of positive TissuGlu outcomes and will support future indication expansions into the US market. TissuGlu Surgical Adhesive is approved in the EU for the approximation of tissue layers where subcutaneous deadspace exists between the tissue planes in large flap surgical procedures such as abdominoplasty.

Mastectomy: Two prospective, randomized Level I studies evaluated TissuGlu in mastectomy procedures with positive preliminary outcomes. Both compared overall invasiveness of standard mastectomies with subcutaneous drains, which generally stay in place from 4-9 days, vs. drain-free mastectomies in which TissuGlu was used to adhere the tissue flap. The first is a single center randomized trial with 61 patients at a German university hospital. Enrollment was completed in May and the study is nearing the end of the patient follow-up period. The second mastectomy trial involved 84 patients from 11 investigator sites in Germany and the UK.

DIEP: Breast reconstruction using an abdominal tissue flap, in a procedure similar to a “tummy tuck”, is considered the gold standard for breast cancer patients in Europe. Prof. Chris Andree of the SANA Clinic in Gerresheim, Germany, an international thought leader in this procedure, has been documenting outcomes using TissuGlu to eliminate drain use in the abdominal donor site. He and his team are nearing completion of a series of 50 patients using this drain-free technique and expect to present their promising outcomes in a publication this fall.

Decubitus: Grade IV decubitus (pressure sores) often require flap surgery for repair, leading to long recoveries. Dr. Reto Wettstein of the Swiss Paraplegic Center in Nottwil, Switzerland is nearing completion of a 15 patient pilot series evaluating TissuGlu for its potential to improve postoperative recovery in decubitus patients. The Center is internationally recognized for their specialization in the management of wheelchair-bound patients.

Ventral Hernia: A pilot series of 10 high BMI patients undergoing open ventral hernia repair (OVHR) is near completion in Germany. The patients are being followed after use of TissuGlu to eliminate postsurgical drain placement. This patient group is at particularly high risk of postoperative wound healing complications, and use of the adhesive without drains may be able to improve outcomes. Similarly, in the Netherlands another pilot series of 15 OVHR patients have undergone procedures using TissuGlu without drain placement. Data from this series is favorable and is expected to be submitted for publication soon.

Mart Pearson, VP Europe for Cohera Medical, Inc. said, “We are very fortunate to be able to work with such an impressive group of clinicians and researchers. This broad range of studies is indicative of the need to improve the wound healing process after flap surgeries and the postoperative recovery for patients. Generating this clinical data will help surgeons everywhere better understand how TissuGlu can help improve their patients’ recovery.”
