Clinical Trial Summary

This is a prospective, single arm, single center clinical study to evaluate efficacy and safety of a Supercritical CO2 viral-inactivated allogenic bone paste in cervical interbody fusion. Patient eligible for 1- or 2-level ACDF (Anterior Cervical Discectomy and Fusion) combined with bone graft after failure of well-conducted medical treatment will be screened for the study.


Description:

Cervical and lumbar fusion are often the best option for various degenerative conditions that do not respond to conservative treatment. Historically, the reference technique for cervical fusion was the use of iliac crest autogenic bone graft (ICBG). However, the use of ICBG has several drawbacks, including the morbidity of the donor site, the increase in operating time and the variable quality of autograft. Alternatives to ICBG for cervical fusion include the use of allografts, graft extensions and osteobiological materials to improve fusion rates. This is a prospective, single arm, single center clinical study to evaluate efficacy and safety of a Supercritical CO2 viral-inactivated allogenic bone paste in cervical interbody fusion. Patient eligible for 1- or 2-level ACDF (Anterior Cervical Discectomy and Fusion) combined with bone graft after failure of well-conducted medical treatment will be screened for the study. Subjects will be followed up postoperatively per standard of care at 3 months, 6 months, 12 and 24 months at the clinic. The following outcomes will be measured: overall success, Neck Disability Index (NDI), VAS neck and arm pain, SF-12 health survey, major complications, subsequent surgery rate, and fusion rate on radiological examinations. The primary endpoint is a FDA composite definition of success comprising clinical improvement and absence of major complications and secondary surgery events.

Outcome

Type Measure Description Time frame Safety issue
Primary Overall subject study success Change from baseline Neck Disability Index (NDI): Patients will be evaluated preoperatively, at 3 months, 6 months, 12 and 24 months
Rate of Adverse Events (AEs) and Serious Adverse Events (SAEs) and reoperations during Follow-up visits
Interbody fusion rate measured by CT scans and standard radiographs at 3 months, 6 months, 12 and 24 months
Overall subject study success is defined as (1) no device or implantation procedure related SAEs; (2) no additional surgical intervention at the operative level, including supplemental fixation, revision, and/or device removal; and (3) minimum 15-point improvement in NDI scores.
3, 6,12 and 24 months
Secondary Pain and Self reported outcomes Change from baseline neck and arm pain measured by Visual Analogue Scale (VAS): Patients will be evaluated preoperatively, at 3 months, 6 months, 12 and 24 months
Change from baseline Health Survey measured by SF-12: Patients will be evaluated preoperatively, at 3 months, 6 months, 12 and 24 months
Potential product benefits assessment by:
Surgery time (from incision to wound closure)
Product ease of use measured by Visual Analogue Scale (VAS) at immediate postoperative visit.
3, 6, 12 and 24 months
