Osteotech’s New Product, GraftCage(TM) ACX, Receives FDA Clearance

EATONTOWN, N.J., Dec. 13 /PRNewswire-FirstCall/ -- Osteotech, Inc. announced today that the Food and Drug Administration ("FDA") has cleared its 510(k) application for the Company's new GraftCage(TM) ACX, for use in the thoracic and lumbar spine, which the Company expects to launch in the first quarter of 2006. The GraftCage(TM) ACX is designed for strength and ease of insertion by surgeons and can be implanted utilizing existing Osteotech instrumentation. The GraftCage(TM) ACX features titanium markers to facilitate intra-operative and post-operative radiographic assessments and an opening for the insertion of bone grafting materials, including a new form of the recently introduced Xpanse(TM) Bone Insert, to allow for maximum graft exposure. This new version of Xpanse(TM) Bone Insert is expected to be launched concurrently with the launch of the GraftCage(TM) ACX.

Sam Owusu-Akyaw, Osteotech's President and Chief Operating Officer, stated, "The GraftCage(TM) ACX is the first in a series of new products from Osteotech manufactured from PEEK material that we expect to introduce into the market over the course of 2006. These products will participate in the overall spinal interbody market, which, in 2005, is approximately $558 million of which PEEK products represent approximately $221 million. Used together, the Xpanse(TM) Bone Insert and GraftCage(TM) ACX create a unique vertebral body spacer allowing for maximum end-plate contact, structural support, osteoinductivity and osteoconductivity, which are the four key functional requirements in order to achieve a successful fusion."

The GraftCage(TM) ACX is intended to replace a collapsed, damaged, or unstable vertebral body in the thoracic or lumbar spine. It is indicated for a partial or total vertebrectomy in cases of tumor or trauma related damage to the vertebral body. The GraftCage(TM) ACX is intended to restore the height of a collapsed vertebral body.
