About this trial

ENCANTO is a randomized, controlled, multi-center phase II clinical trial for the treatment of patellofemoral osteoarthritis (PFOA) with an Advanced Therapy Medicinal Product (ATMP), nasal chondrocyte-based tissue engineered cartilage (N-TEC) implantation in comparison with current standard of care depending on the stage of osteoarthritis. The goal of this phase II trial is to evaluate the efficacy of N-TEC treatment in comparison to an active comparator Autologous Matrix Induced Chondrogenesis (AMIC) for early stage PFOA or patellofemoral arthroplasty (PFA) for late stage PFOA.

The N-TEC engineered cartilage graft is obtained by culturing expanded autologous nasal chondrocytes within a collagen type I/III membrane.

Eligibility criteria

Qualifiers
