We have been discussing the promising initial results of the Bone Biologics (NASDAQ:BBLG) treatment known as NB1, and now the company has announced an important milestone—the first two human patients have been treated in the company’s NB1 bone graft device. This marks the start of the pilot clinical study that will evaluate NB1 in 30 adult subjects who undergo transforaminal lumbar interbody fusion (TLIF) to treat degenerative disc disease (DDD) and will evaluate safety and effectiveness, fusion success, pain, function improvement and adverse events. According to the company, in order to be enrolled in the study, patients must have DDD at one level from L2-S1 and may also have up to Grade 1 spondylolisthesis or Grade 1 retrolisthesis at the involved level. These two initial patients were treated in Australia. As we’ve noted before, the study design was previously reviewed and agreed upon by the U.S. Food and Drug Administration’s Division of Orthopedic Devices in a Pre-submission to support progression to a pivotal clinical trial in the United States.
There are approximately 350,000 spinal fusion surgeries done in the US every year with varying degrees of success in alleviating often debilitating back pain. The existing dominant technology, known as rhBMP, has been quite successful in advancing the spinal fusion procedure but there are also challenges that can come along with using that technology. Patients can experience such impacts as rapid, uncontrolled bone growth that causes an unsound structure and unwanted bone formation where bone will grow where it is not intended. Back pain impacts 65 million Americans, with 16 million of those having what would be considered chronic back pain, leading to an estimated $12 billion per year in health care and indirect cost according to the Georgetown Policy Institute. While spinal fusion surgery isn’t the appropriate treatment for every kind of back pain, it can help to relieve the pain associated with a variety of conditions.
The NELL-1 technology at the heart of NB1 is the centerpiece of what Bone Biologics is developing. It was developed by UCLA TDG and Bone holds the exclusive worldwide rights to that technology. NELL-1 has been reviewed positively in over 45 peer reviewed publications demonstrating technological viability. NELL-1 has shown spine fusion effectiveness across three animal species—rodent, sheep and nonhuman primate and has completed two clinically relevant sheep studies that demonstrated NELL-1 increases the fusion rate and quantity of bone compared to the control group.
