Abstract

No data on inotuzumab ozogamicin (InO) in infant acute lymphoblastic leukaemia (ALL) have been published to date. We collected data internationally on infants/young children (<3 years) with ALL treated with InO. Fifteen patients (median 4.4 months at diagnosis) received InO due to relapsed or refractory (R/R) disease. Median percentage of CD22+ blasts was 72% (range 40–100%, n = 9). The median dose in the first course was 1.74 mg/m2 (fractionated). Seven patients (47%) achieved complete remission; one additional minimal residual disease (MRD)-positive patient became MRD-negative. Six-month overall survival was 47% (95% confidence interval [CI] 27–80%). Two patients developed veno-occlusive disease after transplant. Further evaluation of InO in this subgroup of ALL is justified.
