A Phase 2b/3a Study to Evaluate the Efficacy and Safety of JointStem in Patients Diagnosed as Knee Osteoarthritis
November 7, 2023 updated by: Nature Cell Co. Ltd.
A 48-Weeks, Phase 2b/3a, Double-Blind, Randomized, Placebo Controlled, Multi-center, Superiority Study to Evaluate the Efficacy and Safety of JointStem, Autologous Adipose Tissue Derived Mesenchymal Stem Cells in Patients Diagnosed as Knee Osteoarthritis
This study is a double-blind, randomized, placebo controlled, multi-center, superiority study to evaluate the efficacy and safety of JointStem, autologous adipose tissue derived mesenchymal stem cells (AdMSC), in patients diagnosed as knee osteoarthritis.
Following a 2-week screening period, approximately 140 subjects will be randomly assigned into one of the following two arms in a 1:1 ratio (1 JointStem : 1 Placebo).
After each subject completes 48-Weeks visit (Visit 8) and the data management team confirms all individual data have no issue, the individual database will be locked and the blinding will be open for the statistical analysis.

Description
Inclusion Criteria:
- Subject who had osteoarthritis of knee diagnosed (according to the clinical and American College of Rheumatology Criteria)
- Subject who has ≥ 34 on WOMAC function score at Screening and Baseline
- Subject who has knee pain ≥ 70 mm for one knee out of 100 mm on VAS (Visual Analog Scale) at Screening and Baseline
- Subject who has radiographic evidence of grade 3 osteoarthritis in the study knee based on the Kellgren and Lawrence radiographic criteria.
- Subjects whose knee pain persists for at least 12 weeks (about 3 months) prior to screening and does not improve symptoms with non-operative treatment options
- Subject who is willing to discontinue all pain medications for osteoarthritis except rescue medication (< acetaminophen 3.25 g per day) at least 72 hours prior to screening and throughout the duration of study
- Subject who is willing and able to give written informed consent for participation in the study
Exclusion Criteria:
- Subject who has Body Mass Index (BMI) > 35 kg/m2
