Osteotech Receives Its First Grafton(R) DBM 510(k) FDA Clearance

EATONTOWN, N.J., Nov. 29 /PRNewswire-FirstCall/ -- Osteotech, Inc. announced today that the Food and Drug Administration (“FDA”) has cleared its 510(k) for Grafton Plus(R) DBM Paste for use as a bone graft extender, bone graft substitute and bone void filler in orthopedic procedures.

Sam Owusu-Akyaw, Osteotech’s President and Chief Operating Officer, stated, “The Grafton Plus(R) DBM Paste 510(k) for orthopedic use is the first of five previously reported 510(k) applications that the Company has filed with the FDA covering its family of Grafton(R) DBM products. We are particularly pleased that this 510(k) application has been cleared for all the indications for which we applied. To our knowledge, this is the only DBM product on the market to receive clearance as a bone graft extender, bone graft substitute and bone void filler.”

Mr. Owusu-Akyaw concluded, “We look forward to the FDA clearing, in the near future, the remaining four 510(k) applications covering our Grafton(R) DBM family of products. We have been working diligently with the FDA reviewers on all of our 510(k) applications and we believe that they will receive clearance by the Agency.”

Grafton Plus(R) DBM Paste is a demineralized bone product that has been proven to be osteoinductive in an athymic rat in vivo model as well as being osteoconductive. Further, results of bone formation studies in animals showed that Grafton Plus(R) DBM Paste performed comparably to autograft. Grafton Plus(R) DBM is prepared utilizing a proprietary processing method that has been validated to consistently produce DBM that is osteoinductive in an athymic rat model and has been validated to inactivate a panel of viruses, including: HIV-1, hepatitis B (using a duck hepatitis virus as a model), hepatitis C (using a bovine diarrhea virus as a model), CMV and polio. This validated process is used to further reduce the risk of disease transmission beyond the protection provided by donor testing and screening procedures.
