Assessment of Efficacy and Safety of 3 Different Doses of co.Don Chondrosphere to Treat Large Cartilage Defects
Summary
This is a prospective, randomised, open label, multicentre Phase II clinical trial to investigate the efficacy and safety of the treatment of large defects with 3 different doses of the autologous chondrocyte transplantation product co.don chondrosphere® (ACT3D-CS) in subjects with cartilage defects of the knee. After screening visit patients were booked for arthroscopy and had their cells harvesting from healthy cartilage. After the arthroscopy the patients were randomised in one of the three dose-groups. The cells are cultivated for 8-10 weeks in vitro to develope 3-dimensional spheroids, that are transplanted in an open knee procedure (treatment surgery)into the defect. Patients of all dose groups subsequently followed the same rehabilitation program and had post-surgery visits. The 12-month-visit is defined as final assessment. Then patients have follow-up assessments up to 60 months.
