About

The purpose of this study is to determine whether TissueGene-C, an allogeneic human chondrocytes expressing Transforming Growth Factor(TGF)-b1, is effective and safe in patients with degenerative arthritis.

Full description

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 the Phase 3 clinical trial , we will compare TissueGene-C to placebo in 26, 52 weeks trial with 156 outpatients who have osteoarthritis. The outpatients are randomized to TissueGene-C or placebo in 1:1 ratio, and they will be monitored and recorded in terms of alleviating symptoms, sports activities, function of the knee, and the presence of adverse events.

Patients who had been treated with physical therapy or herbal remedy (acupuncture, heat etc.) within 2 weeks of baseline visit
History of injection within the past 3 months on the target knee
Pregnant or breastfeeding female
With another joint disease apart from degenerative arthritis (e.g., systemic rheumatic inflammatory disease associated with the knee or chondrocalcinosis, hemachromatosis, inflammatory arthritis, necrosis of the trochanter, Paget's disease adjacent to a joint in the femur or tibia, ochronosis, hemophilic arthropathy, infectious arthritis, Charcot's disease in the knee joint, villonodular synovitis, synovial chondromas)
