CellSeed's cartilage cell sheets

Osteoarthritis of the knee is a slowly progressive, intractable articular cartilage degeneration for which there is no fundamental treatment. Due to the aging population, the number of patients is expected to increase. Our company is conducting research and development of regenerative medicine products, including a cartilage cell sheet, which is part of our pipeline aimed at treating knee osteoarthritis. In September 2023, we submitted a clinical trial notification for a Phase III study of our allogeneic cartilage cell sheet (CLS2901C), and we will proceed with the initiation of the Phase III clinical trial.
