What was measured

Time to treatment failure is defined as time to end of study randomized treatment (except for hematopoietic stem cell transplantation \[HSCT\] without loss of MRD-negative CR) due to safety and efficacy reasons. MRD-negative CR is achieved when a participant meets the criteria for both MRD negativity and CR. MRD-negativity: \<=0.01% BCR-ABL1/ABL1, or undetectable BCR-ABL1 transcripts in cDNA with \>=10,000 ABL1 transcripts. CR: meeting all the following for at least 4 weeks (that is no recurrence):1. No circulating blasts and \<5% blasts in the BM. 2. Normal maturation of all cellular components in the BM. 3. No extramedullary disease (CNS involvement, lymphadenopathy, splenomegaly, skin/gum infiltration, testicular mass). 4. ANC \>1000/mcL (or \>1.0\*10\^9/L). 5. Platelets \>100,000/mcL (or \>100\*10\^9/L).
