Summary

This is a Phase I/II clinical trial of gene therapy for treating Fanconi anemia using a self-inactivating lentiviral vector to functionally correct the defective gene. The objectives are to evaluate the safety and efficacy of the gene transfer clinical protocol.

Detailed description

Fanconi anemia is a rare, inherited disease that is caused by a gene defect and that primarily affects an individual's bone marrow, resulting in decreased production of blood cells. The major problem for most patients is aplastic anemia, the blood counts for red blood cells, white blood cells, and platelets are low. In addition, some patients have physical defects usually involving the skeleton and kidneys. Fanconi anemia is typically diagnosed in childhood, and there is a high fatality rate. Hematopoietic stem cell transplantation (HSCT) is a common treatment for Fanconi anemia. However, there are many risks associated with HSCT including rejection of the transplanted cells and graft-versus-host disease. The primary objectives are to evaluate the safety of the self-inactivating lentiviral vector, the ex vivo gene transfer clinical protocol and the efficacy of immune reconstitution in patients overcoming immune abnormalities present at the time of treatment, assessment of gene correction efficiency, and finally the long-term correction of Fanconi anemia associated disease symptoms.
