About Bone Therapeutics

Bone Therapeutics is a leading cell therapy company addressing high unmet needs in orthopaedics and bone diseases. Based in Gosselies, Belgium, the Company has a broad, diversified portfolio of bone cell therapy products in clinical development across a number of disease areas targeting markets with large unmet medical needs and limited innovation.

The Company also has an autologous bone cell therapy product, PREOB^®, obtained from patient's own bone marrow and currently in Phase III development for osteonecrosis of the hip.
