Bone Therapeutics to enhance value of its severe osteoporosis program by transitioning to allogeneic development
Recent encouraging efficacy data with PREOB® in osteoporosis combined with positive efficacy and safety data in other allogeneic programs supports new strategy
Gosselies, Belgium, 19 May 2016 - BONE THERAPEUTICS (Euronext Brussels and Paris: BOTHE), the bone cell therapy company addressing high unmet medical needs in the fields of bone fracture repair, fracture prevention and spinal fusion, today announces that it plans to commence a Phase II trial for the treatment of severe osteoporosis with its allogeneic “off the shelf”1 bone cell therapy product, ALLOB®.
Enrico Bastianelli, Chief Executive Officer of Bone Therapeutics commented: "Bone Therapeutics’ allogeneic product has several advantages with regards to dosing, logistics and scalability, which offer potential benefits for commercialisation in a larger patient population. Following encouraging preliminary data from the osteoporosis study with our autologous product PREOB®, combined with promising efficacy and safety results obtained with ALLOB® in other studies, we believe investigating ALLOB’s potential in severe osteoporosis, instead of PREOB®, could create a better solution for patients and enhance value creation from a partnership deal for this product."
Osteoporosis is a condition characterized by an excessive loss of bone mass due to impaired bone turnover. The natural balance between bone formation and bone resorption is disturbed, leading to bone fragility and increased fracture risk. The disease affects a large population of more than 30 million patients in Europe and the US, with the total market estimated to be worth up to $8.4 billion, of which up to 30% does not respond to available therapies, so called “severe” osteoporosis.
The encouraging results of the first cohort of patients in the Phase IIA trial of PREOB® for severe osteoporosis demonstrated a sustained beneficial effect from a single intravenous PREOB® administration on pain and bone turnover markers. Additional biomarker analyses confirm the trends observed during the 12-month follow-up period. In an early phase, a decrease in bone resorption markers were observed, as well as a limited decrease in bone formation markers. In later phases, while bone resorption markers tend to re-increase, bone formation markers2 show a progressive increase. Interestingly, the inhibitors of bone formation3 show a clear decrease up to 12 months. Overall, these preliminary data seem to indicate that bone resorption is reduced in the first months after PREOB® administration, while the formation of new bone is stimulated in later phases.
The preparation for the Phase II trial with ALLOB® for the treatment of severe osteoporosis has already started and the trial is expected to commence early in 2017.

1 Allogeneic", or “off the shelf” therapies are those in which the cells are harvested from healthy donors, as opposed to “autologous” where the cells come from the patient him/herself.
2 Relevant bone-formation markers include CTX, B-ALP, P1NP, osteocalcin, IGFBP-1 and periostin.
3 Inhibitors of bone formation include SOST and IGFBP-7.
