A Study of NCR100 Injection for the Treatment of Knee Osteoarthritis（ KOA）

Phase 1

Not yet recruiting

• Conditions: Knee Osteoarthritis
• Interventions: Biological: NCR100; Other: 0.9% Normal saline

• Registration Number: NCT06741098
• Lead Sponsor: Nuwacell Biotechnologies Co., Ltd.

Brief Summary

This clinical study is to investigate the safety and efficacy of NCR100 injection in subjects with knee osteoarthritis (KOA). It contains two parts dose-escalating, and blind random study in adult KOA subjects.

Detailed Description

Knee osteoarthritis(KOA) is a kind of degenerative joint disease characterized by chronic inflammation loss of articular cartilage and subchondral bone remodeling.In China, the estimated number of patients diagnosed with KOA reached 37.35millon. The aim of this sudy is to evaluate the safety tolerability and efficacy of human pluripotent stem cell derived mesenchymal stromal cells (NCR100) injection in the treatment of subjects with knee osteoarthritis.
