简要总结
The primary purpose of the this study is to evaluate the safety of TissueGene-C, a gene therapy product that uses allogenic human chondrocytes expressing Transforming Growth Factor(TGF)-β1 by assessing the inflammation at the injection site, the incidence and severity of the adverse events, the physical examination findings, and the laboratory test results after the intra-articular injection of TissueGene-C.
And Secondary purpose is to evaluate the biological efficacy (knee pain, range of motion, functional tests, and MRI) of TissueGene-C and the distribution of TissueGene-C outside the injection site.
详细描述
TissueGene-C is a biological new drug which consists of normal chondrocyte cells and transduced chondrocyte cells that express growth factor to modify osteoarthritis symptom for long term period.
During clinical trial Phase 1, we compare three different dose levels of TisssueGene-C in 6 months with 12 outpatients with degenerative arthritis. The patients are randomized by three different dose levels of TisssueGene-C in 1:1:1 ratio, and they are monitored and recorded for alleviating symptoms, sports activities, function of the knee, and the presence of adverse events.
