Screening for eligible participants will be performed within 21 days before administration of the study drug. Participants with B-cell ALL/LL will receive treatment until disease progression, unacceptable toxicity or achievement of CR followed by hematopoietic stem cell transplant (HSCT). Participants with T cell ALL/LL will receive treatment for up to 2 cycles. If disease progression is confirmed, then the participant will discontinue study treatment, complete the End of Treatment Visit, and enter the Posttreatment Period. For those participants who discontinue study drug prior to disease progression, disease evaluations will continue to be performed every 8 weeks until subsequent anticancer therapy is initiated.
