Owing to the poor prognosis of relapsed or refractory acute lymphoblastic leukemia (ALL), hematopoietic stem cell transplantation (HSCT) followed by effective salvage therapy is required. Inotuzumab ozogamicin (INO) was developed for ALL refractory to standard chemotherapy. However, previous reports suggest that sinusoidal obstruction syndrome (SOS) risk increases in patients with HSCT receiving INO, especially with dual alkylating agents. We report a case of relapsed Philadelphia chromosome-negative B-ALL where the patient underwent haploidentical HSCT using fludarabine/total body irradiation conditioning and posttransplant cyclophosphamide. Successful engraftment was achieved without SOS development.
