We are also accelerating the clinical development of ALLOB, Bone Therapeutics’ scalable allogeneic cell therapy platform. In addition, we are building on our success in orthopedics and moving our formidable Mesenchymal stromal cell (MSC) capabilities to target wider indications. These developments make it even more important for Bone Therapeutics to have a CMO with the experience to match our recently appointed CSO,” said Miguel Forte, CEO, Bone Therapeutics. “Anne Leselbaum has extensive professional experience in bringing advanced therapeutics through the clinical stage to marketing authorization. This includes her experience with Takeda’s approved allogeneic cell therapy product, Alofisel. In addition to her experience of building strong connections with key opinion leaders, her interactions and existing relationships with regulators, specifically the EMA and FDA will also be vital at this stage.”

It is also continuing with clinical development of its allogeneic cell therapy platform ALLOB, and using its considerable MSC experience to target wider indications outside orthopedics,” said Anne Leselbaum, MD, Chief Medical Officer of Bone Therapeutics. “Whilst the cell and gene therapy sector continues to develop, joining Bone Therapeutics, which is seeking to commercialize one therapy whilst moving into whole new areas of cutting edge research and clinical development is an excellent opportunity. I look forward to combining my experience with that of Bone Therapeutics’ senior team to drive its therapies to patients of a range of therapies with few alternative options.”

About Bone Therapeutics

Bone Therapeutics is a leading biotech company focused on the development of innovative products to address high unmet needs in orthopedics and other diseases. The Company has a, diversified portfolio of cell and biologic therapies at different stages ranging from pre-clinical programs in immunomodulation to mid-to-late stage clinical development for orthopedic conditions, targeting markets with large unmet medical needs and limited innovation.

Bone Therapeutics is developing an off-the-shelf next-generation improved viscosupplement, JTA-004, which is currently in Phase III development for the treatment of pain in knee osteoarthritis. Consisting of a unique combination of plasma proteins, hyaluronic acid - a natural component of knee synovial fluid, and a fast-acting analgesic, JTA-004 intends to provide added lubrication and protection to the cartilage of the arthritic joint and to alleviate osteoarthritic pain and inflammation. Positive Phase IIb efficacy results in patients with knee osteoarthritis showed a statistically significant improvement in pain relief compared to a leading viscosupplement.

Bone Therapeutics’ core technology is based on its cutting-edge allogeneic cell therapy platform with differentiated bone marrow sourced Mesenchymal Stromal Cells (MSCs) which can be stored at the point of use in the hospital. Currently in pre-clinical development, BT-20, the most recent product candidate from this technology, targets inflammatory conditions, while the leading investigational medicinal product, ALLOB, represents a unique, proprietary approach to bone regeneration, which turns undifferentiated stromal cells from healthy donors into bone-forming cells. These cells are produced via the Bone Therapeutics’ scalable manufacturing process. Following the CTA approval by regulatory authorities in Europe, the Company has initiated patient recruitment for the Phase IIb clinical trial with ALLOB in patients with difficult tibial fractures, using its optimized production process. ALLOB continues to be evaluated for other orthopedic indications including spinal fusion, osteotomy, maxillofacial and dental.

Bone Therapeutics’ cell therapy products are manufactured to the highest GMP (Good Manufacturing Practices) standards and are protected by a broad IP (Intellectual Property) portfolio covering ten patent families as well as knowhow. The Company is based in the BioPark in Gosselies, Belgium. Further information is available at www.bonetherapeutics.com.
