The Use of Autologous Bone Marrow Mesenchymal Stem Cells in the Treatment

Status Recruiting

Clinical Trial Summary

This study is conducted to assess whether implanting autologous, culture-expanded, mesenchymal stem cells obtained from the bone marrow of patients with early osteoarthritis, cartilage defects or cartilage and underlying bone and cartilage (osteochondral) defects in joints is effective in the treatment of such conditions and alleviation of patients symptoms.

Clinical Trial Description

All procedures are carried out after obtaining informed written consent from patients. Bone marrow is aspirated from the iliac crest (hip bone) of patients with osteochondral defects intraoperatively under complete sterile, aseptic conditions and under proper anaesthesia (general, local). The bone marrow aspirate is placed in tubes and transferred under aseptic conditions to the Tissue Culture Unit in the Biochemistry Department at the Cairo University School of Medicine where it is processed and bone marrow mesenchymal stem cells are isolated and grown in culture for 2-3 weeks. After this time interval, the cells are reprocessed and the cell pellet is obtained. Implantation of the cell pellet into the osteochondral defect of the joint after embedding it on a proper scaffold is performed followed by subsequent defect coverage with an autologous periosteal flap obtained from the proximal tibia to seal the defect and maintain the cell pellet in place. The patients will be assessed clinically with scoring systems preoperatively as well as 6 and 12 months postoperatively to assess relief of symptoms and joint function. Radiological assessment (X-rays and MRIs)of the affected joints will be performed at the same time points aforementioned to assess integrity of the formed cartilage. Second look arthroscopy and biopsy will also be performed to histologically assess the repair tissue and grade it via arthroscopic grading system according to the International Cartilage Repair Society guidelines. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
