Brief Summary

In this study, adults with newly-diagnosed Philadelphia Chromosome-positive acute lymphoblastic leukemia (Ph+ ALL) will receive first-line therapy of ponatinib or imatinib.

The main aim of this study is to compare the number of participants on each treatment that show no signs of disease.

Participants will take tablets of either ponatinib or imatinib at the same time each day combined with reduced-intensity chemotherapy for up to 20 months. Then, they will continue with single-agent therapy (ponatinib or imatinib) until they meet the discontinuation criteria from the study.

Detailed Description

The drug being tested in this study is called ponatinib. Ponatinib is being tested to treat people who have newly diagnosed Ph+ ALL. This study will look at the efficacy of ponatinib in participants in addition to standard care.

The study will enroll approximately 230 participants. Participants will be randomized in a 2:1 ratio to receive oral ponatinib or imatinib (Cohort A and Cohort B, respectively) daily throughout the study.

All participants will be asked to take ponatinib or imatinib at the same time each day with reduced-intensity chemotherapy in induction phase (Cycles 1 to 3), consolidation phase (Cycles 4 to 9) and maintenance phase (Cycles 10 to 20). At the end of the 20 cycles, participants will remain on ponatinib or imatinib (administered as a single agent). The dose of ponatinib in consolidation and maintenance phase will start with the last dose given in the previous phase. The dose can be modified based on MRD-negative CR results.

This multi-center trial will be conducted in Argentina, Australia, Austria, Belarus, Brazil, Bulgaria, Canada, Chile, France, Mexico, Greece, Italy, Japan, Korea, Republic Of, Poland, Romania, Russia, Spain, Taiwan, Province Of China, Turkey, Finland and the United States. Participants including those who achieve a clinical response, may receive study drug until they are deceased, have failed to achieve the primary endpoint, have experienced relapse from CR or have progressive disease, have an unacceptable toxicity, have withdrawn consent, have proceeded to HSCT, or until the sponsor terminates the study, whichever occurs first. After disease progression, all participants will be contacted every 3 months for survival follow-up. Participants will be followed until completion of the study or until the participant's death has been reported.

Percentage of Participants With Primary Induction Failure (PIF)Up to 3 months

PIF is defined as participants who received treatment for ALL but never achieved CR or CRi by the end of induction. PIF is not limited by the number of unsuccessful treatments; this disease status only applies to recipients who have never been in CR or CRi. CR is defined as 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). CRi is defined as hematologic complete remission with incomplete hematologic recovery and meeting all criteria for CR except platelet count and/or ANC.

Duration of MR4.5Up to approximately 3 to 6 years

Duration of MR4.5 is defined as interval between the first assessment at which the criteria for MR4.5 are met until the earliest date at which loss of MR4.5 occurs. MR4.5 is molecular response 4.5-log reduction (\<=0.0032% BCR-ABL1/ABL1), or undetectable BCR-ABL1 transcripts in cDNA with \>=32,000 ABL1 transcripts.

Duration of MRD-Negative CRUp to approximately 3 to 6 years

Duration of MRD-negative CR is defined as interval between the first assessment at which the criteria for MRD-negative CR are met until the earliest date at which loss of MRD negativity or relapse from CR occurs. MRD negativity (MR4): \<=0.01% BCR-ABL1/ABL1, or undetectable BCR-ABL1 transcripts in cDNA with \>=10,000 ABL1 transcripts. CR is defined as 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). Relapse from CR: Reappearance of blasts in the blood or BM (\>=5%) or in any extramedullary site after a CR.

Duration of CRUp to approximately 3 to 6 years

Duration of CR is defined as interval between the first assessment at which the criteria for CR are met until the earliest date at which relapse from CR occurs. CR is defined as 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). Relapse from CR: Reappearance of blasts in the blood or BM (\>=5%) or in any extramedullary site after a CR.
