Institutional Review Board, Hospital for Special Surgery
The safety of our participants is our top priority. The trial/study is approved and periodically reviewed by the Institutional Review Board (IRB), which includes doctors, administrators, ethicists, and members of the general public. The safety of clinical trials is reviewed by the U.S. Food and Drug Administration.
Before enrolling in a clinical trial or research study, the investigator will explain the purpose of the trial/study, its expected benefits, any possible risks or side effects, and what your role will be. If you want to join the trial/study, you must sign informed consent documents. You can leave a trial/study at any time without penalty.

Summary
We are conducting a study investigating the effects of of JointStem, an autologous adipose tissue-derived mesenchymal stem cell injection, in patients with knee osteoarthritis. This product consists of adult stem cells that are isolated from a patient’s own abdominal fat tissue and expanded to the desired dose for injection, and it is administered to synovial cavity to improve symptoms and to delay the progression of osteoarthritis by regenerating and restoring damaged cartilage. Please note that this is a randomized blinded study, with study participants receiving either the JointStem injection or a placebo control injection in a 1:1 ratio. If you qualify for this study the costs of lipoaspiration and injection would be completely covered.
• 2-week Screening period, 48-week treatment to follow up period
• 140 subjects to be randomized
– 12 month enrollment period, competitive enrollment
• Subjects are randomly assigned into one of the following two arms in a 1:1 ratio (1 JointStem : 1 Placebo):
– Test product: JointStem (1x108 cells in 2.1mL Normal Saline with 0.9mL Autologous Serum)
– Placebo control: 2.1mL Normal Saline with 0.9mL Autologous Serum

- Subject who has history of stem cell therapy
- Subject who have significant lab abnormalities for the following parameters (If the value is within 10% of the listed laboratory exclusion criterion value and the value is considered not to be clinically significant by the investigator, the subject can be considered for enrollment):
