Bone Therapeutics completes recruitment of the first half of patients in ALLOB® Phase IIA spinal fusion trial

ALLOB®’s positive safety profile confirmed at mid-point in trial

Gosselies, Belgium, 15 December 2015 - BONE THERAPEUTICS (Euronext Brussels and Paris: BOTHE), the bone cell therapy company addressing high unmet medical needs in the field of bone fracture repair and bone fracture prevention, today announces it has successfully completed recruitment of the second cohort of four patients in its ALLOB® Phase IIA spinal fusion trial without any safety concerns. Recruitment for this trial remains on track at the midpoint of the trial, with eight out of a total of 16 patients treated.

Spinal fusion is considered the gold standard for the treatment of a broad spectrum of spine disorders and aims to relieve pain and improve function. Approximately one million spinal fusion surgeries are performed each year in Europe and the US (of which approximately half involve lumbar spinal fusion)1 and the global market is estimated to reach $7 billion by 2017.2 Although spinal fusion surgery is routine, it is associated with failure rates of up to 35%.3 Bone Therapeutics’ cell therapy product ALLOB® has been designed to accelerate the fusion process and reduce the failure rate of current surgeries.
The pilot Phase IIA study will enrol 16 patients with symptomatic degenerative lumbar disc disease who require interbody fusion surgery.4 An interbody cage is implanted according to the standard-of-care surgical approach, which will be supplemented with ALLOB® in combination with bioceramic granules. Safety and efficacy of this treatment will be assessed over 12 months, using clinical and radiological evaluation. The trial is currently running in eight centres across Belgium. Today, the procedure has been performed in eight patients without any complications or safety issues.
ALLOB® is also being evaluated in the treatment of delayed-union fractures and has already reported strong safety and efficacy results. Recently, the Company initiated a novel Phase IIA study with ALLOB® for the treatment of patients with failed spinal fusions. This is the first minimally invasive revision spinal surgery using a bone cell therapy product.

Enrico Bastianelli, CEO of Bone Therapeutics commented: "We are pleased to report today that the spinal fusion trial is on schedule with half of the patients now treated without any safety concerns. We expect to update the market in the first half of 2016 on the efficacy of ALLOB® in the first cohort patients in this trial after the 12-month follow-up period. The excellent safety and efficacy results reported for ALLOB® so far reinforce our confidence in the success of the product and we look forward to further positive data in 2016".

4 Interbody fusion is a type of spinal fusion surgery that involves removal of the disc between two vertebral bodies. To maintain the normal alignment of the spine, an implant, such as a spacer or cage, will be inserted in the space created by the removal of the disc. Subsequently, a bone graft or bone graft substitute is placed between the neighbouring vertebrae to stimulate the fusion process.
