Adherus™ Dural Sealant in Spinal Procedures

This is a prospective, randomized, controlled, single-blind, multicenter, pivotal trial that will evaluate the safety and effectiveness of Adherus Dural Sealant when used in conjunction with standard methods of dural repair in spinal procedures. This trial uses the commercially available DuraSeal Exact as an active control. The trial is designed to demonstrate non-inferiority of Adherus Dural Sealant to DuraSeal Exact. Subjects who are undergoing spinal surgery, consent to participate in this trial and experience a durotomy will be considered for study enrollment. Following a two-tiered inclusion/exclusion consideration, subjects will be randomized intraoperatively using a 1:1 randomization ratio. Up to 90 subjects will be randomized to treatment with either Adherus Dural Sealant or DuraSeal Exact with at least 50% of subjects undergoing procedures at lumbar or lumbosacral levels. Up to 30 investigational sites within the United States will participate in this trial. A primary composite endpoint evaluating safety and effectiveness will be measured within a 90-day required follow-up period post-procedure. Subjects will be followed at discharge or between postoperative days (POD) 1-4 from the index procedure (whichever occurs first) and at 30 days and 90 days post-index procedure.
