Trial Comparing BST-CarGel and Microfracture in Repair of Articular Cartilage Lesions in the Knee

A Randomized, Comparative Multicenter Clinical Trial Evaluating BST-CarGel™ and Microfracture in Repair of Focal Articular Cartilage Lesions on the Femoral Condyle

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 80 (actual)

• Healthy volunteers: Not accepted

Summary

This study will investigate whether the treatment of damaged cartilage in the knee with BST-CarGel will increase the amount and quality of cartilage repair tissue when compared with microfracture alone. Furthermore, the effect of BST-CarGel in decreasing cartilage related pain and improving cartilage-related function in the knee will be assessed.

Detailed description

Cartilage repair currently remains a problematic orthopedic concern with no effective solution. The development of new surgical techniques or therapies is critical in meeting this medical need. This Canadian trial will be a pivotal protocol study, conducted as a randomized, controlled trial. A total of 80 subjects, 40 subjects in each of the two groups (BST-CarGel applied to a microfractured lesion or microfracture alone), will be enrolled in this study. The subjects and investigative medical staff will not be blinded to treatment due to the difference in surgical incision size. However, although the treatment will not be blinded, the primary effectiveness assessment will be blinded. The primary endpoint of this study will be cartilage repair at 12 months proved by demonstrating that BST-CarGel treatment effectively fills cartilage lesions with high quality cartilaginous tissue. The secondary endpoints will be pain, stiffness and function while other tertiary endpoints will include safety, quality-of-life (QOL), as well as macroscopic characterizations of tissue repair. The primary measure of this study will occur at 12 months, when imaging of repair tissue using magnetic resonance (MR) and associated analyses will compare tissue volume, quality and other anatomical variables. Radiographic evaluations will be blinded. Volunteer biopsies at 13 months may be obtained. Pain, stiffness, function and QOL will be assessed prior to treatment, and at 3, 6 and 12 months following treatment using self-administered validated scores (WOMAC and SF-36). In addition, subject safety will be assessed through a record of adverse events.
