Autologous bone marrow transplantation (BMT) was utilized as therapy for 23
patients with acute lymphoblastic leukemia (ALL) in second or greater
remission. Bone marrow was treated in vitro with a combination of
monoclonal antibodies, consisting of BA-1, BA-2, BA-3, and baby rabbit
complement (BRC'). All patients were prepared for transplantation with
cyclophosphamide and fractionated total body irradiation. Engraftment
occurred in all 23 patients. Seven of 23 patients remain relapse-free from
six to 32 months (median, 21.4 months) posttransplant. Failures were due to
relapse with the exception of one patient who died of infection. This study
demonstrates that autologous BMT using in vitro marrow treatment with BA-1,
BA-2, BA-3, and BRC' is safe, allows engraftment, and results in prolonged
survival for some patients with ALL in second or greater remission.
