Provisional patent for Bone Graft Substitute formulation submitted

Collagen Solutions plc (AIM: COS), the developer and manufacturer of medical grade collagen components for use in regenerative medicine, medical devices and in-vitro diagnostics, announces it has submitted a provisional US patent application covering novel properties of a Bone Graft Substitute formulation.

The provisional patent is related to the Company's development programme for a novel Bone Graft Substitute that addresses approximately 30% of a $1.7 billion orthopaedic market for Bone Graft Substitutes in the United States. The provisional patent leverages the Company's extensive experience in the development of Bone Graft Substitute formulations and covers several novel, proprietary characteristics. These characteristics, which are related to the formulation's superior handling properties and inorganic particle retention, will enhance ease-of-use for the surgeon and ensure that the substitute remains at the operative site. The next steps in the development programme will be to finalise the device design and initiate animal studies which will be used in a 510(k) application for FDA approval.

Jamal Rushdy, CEO of Collagen Solutions, said: "We are encouraged by our Bone Graft Substitute product development work thus far, and this provisional patent application is a step towards realising the commercial potential of this project. In addition to our extensive internal expertise, we are guided by our recently-formed Scientific Advisory Board, which includes members with strong experience and demonstrated successes in the Bone Graft Substitute market."
