WARNING: DIFFERENTIATION SYNDROME
Patients treated with XOSPATA have experienced symptoms of differentiation syndrome, which can be fatal or life-threatening if not treated. Symptoms may include fever, dyspnea, hypoxia, pulmonary infiltrates, pleural or pericardial effusions, rapid weight gain or peripheral edema, hypotension, or renal dysfunction. If differentiation syndrome is suspected, initiate corticosteroid therapy and hemodynamic monitoring until symptom resolution.

*FLT3 mutation status: FLT3-ITD, FLT3-TKD, and FLT3-ITD-TKD.2

The OS endpoint was measured from the date of randomization until death by any cause in the final analysis, which included 371 patients randomized 2:1 to receive XOSPATA or a prespecified salvage chemotherapy regimen.2

CR defined as normal marrow differential with <5% blasts, ANC ≥1.0 x 109/L and platelets ≥100 x 109/L, no evidence of extramedullary leukemia, and must have been RBC and platelet transfusion independent.2

§CRh defined as marrow blasts <5%, partial hematologic recovery, ANC ≥0.5 x 109/L and platelets ≥50 x 109/L, no evidence of extramedullary leukemia, and could not have been classified as CR.2

AML=acute myeloid leukemia; ANC=absolute neutrophil count; CI=confidence interval; CR=complete remission; CRh=complete remission with partial hematologic recovery; FLT3=FMS-like tyrosine kinase 3; HR=hazard ratio; ITD=internal tandem duplication; m+=mutation-positive; NCCN=National Comprehensive Cancer Network; OS=overall survival; RBC=red blood cell; TKD=tyrosine kinase domain.
