Disposition of patients in the study. *Reasons for not meeting eligibility criteria included: MRD level lower than the required ≥10⁻³ (therefore, inclusion criterion not fulfilled because disease burden too low; n = 48); not in hematologic CR (ie, overt relapse; n = 31); technical (n = 5); central nervous system relapse (n = 2); active infection (n = 2); alternative therapy (n = 2); neurologic disorder (n = 2); CD19⁻ (n = 1); hepatic disorder (n = 1); and consent withdrawn (n = 1). †Reasons for discontinuation (n = 33) included: adverse event (n = 20 [17.2%]), disease relapse (n = 10 [8.6%]), physician decision (n = 2 [1.7%]), and other (n = 1 [0.9%]). DOR, duration of hematologic remission; LLOQ, lower limit of quantitation; RFS, relapse-free survival.
