Abstract

Bone Therapeutics develops innovative osteoblastic cell therapy products for the treatment of orthopedic and spinal conditions. The company is currently evaluating its human allogeneic osteoblastic cell therapy product, ALLOB®, in spinal fusion. Although spinal fusion is routine procedure, non-union and persisting pain is still frequent irrespective of the procedure and bone graft used. The local implantation of osteoblastic cells (such as ALLOB®) in combination with bioceramics granules is expected to provide the necessary osteogenic, osteoinductive and osteoconductive properties for the enhancement of bone formation and fusion. Preclinical studies with ALLOB® have shown excellent safety and efficacy results. For example, in a mouse model of osteotomy, combining granules with ALLOB® significantly accelerates and increases the bone formation and fusion rates as compared to granules alone (fusion was observed in 40% vs. 17% at 4 weeks and in 60% vs. 0% at 8 weeks for the animals treated with ALLOB®/bioceramics and with bioceramics alone respectively). Bone Therapeutics has initiated a proof-of-concept Phase IIA open-label study to assess the safety and efficacy of ALLOB® in patients requiring spinal fusion procedures. Sixteen patients with symptomatic lumbar disc disease will be treated with a single dose of ALLOB® combined with β-TCP granules to promote bone formation and fusion of the vertebral bodies. The ALLOB®-treated patients will be evaluated over a 12-month period using both clinical and radiological parameters. To date, the first two patient cohorts have been treated without any complications or safety issues.
