Cerapedics announces i-FACTOR biologic bone graft study results in PLIF spine surgery

Cerapedics, Inc., a medical device company focused on developing and commercializing novel osteobiologic products, announced the results of a prospective, randomized, controlled trial of its i-FACTOR™ biologic bone graft for patients undergoing posterior lumbar interbody fusion (PLIF) spine procedures. The trial was performed by Philippe Lauweryns, MD, PhD from the Department of Orthopaedic Surgery, Regionaal Ziekenhuis Sint Trudo Hospital in Sint Truiden, Belgium.

The objective of the study was to evaluate the safety and efficacy of Cerapedics’ novel i-FACTOR biologic bone graft compared to autologous bone delivered via interbody fusion cages in single- and multi-level PLIF surgery. All patients served as their own control and also received posterior pedicle screw instrumentation. Outcomes included VAS for pain, Oswestry Disability Index (ODI) and radiographic images. The occurrence of complications or adverse events was also recorded. In addition to x-rays, the study utilized CT scans taken at 6-month and 1-year intervals. Fusion at the operative levels was defined as the presence of “bridging bone” and was assessed by a board certified independent radiologist.

At 6- and 12-months after treatment, data from 40 patients (45 levels) demonstrated superiority of i-FACTOR biologic bone graft over autologous bone. A radiological fusion rate of 97.7% for patients treated with i-FACTOR compared to 59.1% for patients treated with autograft (p<0.01). These results compare with the one-year data, which demonstrated a radiological fusion rate of 97.8% for patients treated with i-FACTOR compared to 82.2% for patients treated with autograft (p<0.01). No wound problems, infection, hematoma nor radicular pain problems were reported in either group.
