Full description

A Phase I, Randomized, Single-centered, Double-blinded Clinical Trial of Allogenic Adipose Tissue-Derived Mesenchymal Progenitor Cells Therapy for Knee Osteoarthritis.

This is a randomized,single-blind, double-blinded,phase I clinical trial. Subjects who are with a clinical diagnosis of knee osteoarthritis cartilage defects and will be randomly distributed 1:1:1 to different dosage group after signing the ICF and screening tests.The treatment will accept Allogenic ReJoinTM at the first and fourth week.The duration of the therapy is 48 weeks.

Enrollment: 22 patients

Sex: All

Ages: 18 to 70 years old

Volunteers: No Healthy Volunteers
