简要总结
The purpose of this study is to evaluate the safety and preliminary efficacy of NeoFuse in subjects with a diagnosis of degenerative disc disease (DDD) at 2 or more adjacent cervical vertebral levels between C3-C4 to C7-T1. All subjects in this study will undergo 2 or 3 level anterior cervical discectomy and fusion with Anterior Cervical Plate Fixation.
详细描述
This is a prospective, multicenter, randomized, single-blinded, controlled study evaluating safety and preliminary efficacy of immunoselected, culture-expanded, nucleated, allogeneic MPCs (NeoFuse) combined with MasterGraft Matrix in a commercially available PEEK cervical Spacer compared to an active control in subjects undergoing 2 or 3 level anterior cervical discectomy and fusion with anterior cervical plate fixation.
After the screening and surgical visits, each subject will be evaluated clinically and radiographically within 3 days and 30 days after surgery, and at 3, 6, 12, and 24 months after surgery.
Subjects will be evaluated at the same time points for safety.

盲法说明
This is a single-blinded study. The study participants will be blinded to the study randomisation assignment and study treatment they receive. In addition, every effort will be made by the Sponsor and Investigator to maintain the study blind. Treatment assignment will occur in sequential chronological order according to a central master list of random assignments prepared by the study statistician (master randomization list).
