Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The aim of this study is to prospectively investigate the potential for bony fusion of ViviGen® bone graft substitute in comparison to rhBMP-2 in monosegmental ALIF procedure L5/S1 and in monosegmental XLIF procedure L4/5

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The investigator hypothesize that

\- The bony fusion rate on a 12-month CT scan (or earlier at 6-month CT scan) is less than 10% lower in the intervention group compared to the bony fusion rate in the control group

For patients included in the study, all follow-up is recorded, with regards to radiological and clinical outcome. Follow up will be evaluated after 14 days, 6 weeks, 6 and 12 months. Last follow up will be 1 year after surgery.

Study Design

Understand how the trial is structured, including allocation methods, masking strategies, primary purpose, and other design elements.

Allocation Method

RANDOMIZED

Intervention Model

PARALLEL

The study is a prospective randomized assessor blind monocentric trial. It aims for non-inferiority.
Primary Study Purpose

OTHER

Blinding Strategy

SINGLE

Outcome Assessors
The CT Reviewer and data analysts, will be blinded as to which bone graft treatment the patient received. Blinding is ensured by coding the electronic case report forms (eCRFs)/ database and images.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Intervention group 5-5.4 cc ViviGen®

Biological: 5-5.4 cc ViviGen® The ALIF or XLIF fusion patients assigned to this group will receive 5-5.4 cc ViviGen®

Group Type ACTIVE_COMPARATOR

ViviGen®

Intervention Type OTHER

It will investigate the radiological and clinical outcome of ALIF procedure L5/S1 and XLIF L4/L5 procedure using two arms/ treatments, namely either ViviGen® Bone Matrix (intervention group) or rhBMP-2 (control group). ViviGen®/ rhBMP-2 ratio will be 1:1.

Control group 4-6mg rhBMP-2

Biological: 4-6mg rhBMP-2 The ALIF or XLIF fusion patients assigned to this group will receive 4-6mg rhBMP-2

Group Type ACTIVE_COMPARATOR

rhBMP-2

Intervention Type OTHER

It will investigate the radiological and clinical outcome of ALIF procedure L5/S1 and XLIF L4/L5 procedure using two arms/ treatments, namely either ViviGen® Bone Matrix (intervention group) or rhBMP-2 (control group). ViviGen®/ rhBMP-2 ratio will be 1:1.
