Bone Repair Cell (BRC) Treatment of Patients With Osteonecrosis of the Femoral Head
Multi-center Clinical Trial of the Application of Tissue Repair Cell (TRC) Therapy of Osteonecrosis of the Femoral Head

The purpose of this study is to determine if autologous Bone Repair Cell (BRC) grafting with demineralized bone matrix bound in autologous plasma after core decompression surgery (BRC therapy) is superior to core decompression with demineralized bone matrix bound in autologous plasma (Control therapy) in preventing progression of osteonecrosis to a more severe disease stage (Stage II to III or higher) from the time of surgery until 24 months later, in patients with University of Pennsylvania (UPenn) Stage IIB or C disease at diagnosis.

This study is an event-driven, multi-center, prospective, independent observer-blinded, controlled, randomized Phase III clinical trial enrolling patients diagnosed with University of Pennsylvania (Steinberg) Classification Stage IIB or C osteonecrosis of the femoral head.

  • The first patient group is the Treatment Group and will receive core decompression and treatment with BRCs and demineralized bone matrix bound in autologous plasma, and
  • The second patient group is the Control Group and will receive core decompression and demineralized bone matrix bound in autologous plasma, without any BRCs.
  • Enrollment: With an anticipated drop-out rate of 10% in up to twenty (20) sites, a total of approximately 135 patients will be enrolled and randomized to obtain 120 evaluable patients (75 for the TRC treatment group and 45 for the Control treatment group).
  • Primary endpoint: The percentage of patients progressing to a more severe UPenn disease stage (Stage II to III or higher) between 0 and 24 months will be the primary efficacy variable to demonstrate TRC therapy is superior to Control therapy.

  • Patients who will require continuous, systemic, high dose corticosteroid therapy (more than 7.5 mg/day) within 6 months after surgery.
  • Patients in active treatment for cancer or blood dyscrasia, or have received chemotherapy, radiotherapy or immunotherapy in the past 2 years.
  • Immunodeficiency diseases.
  • Participation in another clinical study in the past 30 days or concurrent participation in another clinical trial.
