Trial Outcomes & Findings for Study of SyntheCelTM Dura Replacement to Other Dura Replacements (NCT NCT00859508)

NCT ID: NCT00859508

Last Updated: 2012-03-08

Results Overview

The primary endpoint for measuring effectiveness is such that an individual patient's treatment success requires the absence of CSF fistula (drainage from wound or sinus) and pseudomeningocele within 6 months post-operatively confirmed by radiographic evaluation and physical examination of the surgical site.

Participant Flow

The trial was approved to enroll subjects from a maximum of 10 US medical institutions (public and academic research center hospitals). Subjects were enrolled from February 2006 to June 2008.

A total of 105 patients that initially met the inclusion/exclusion criteria were enrolled and randomized. Of those 105 patients, 99 received surgical treatment. Of those not treated, reasons included: change in diagnosis, not meeting Inclusion/Exclusion criteria, subject voluntary withdrawl, and investigator decision.
