Trial Outcomes & Findings for A Study of Ponatinib Versus Imatinib in Adults With Acute Lymphoblastic Leukemia (NCT NCT03589326)

NCT ID: NCT03589326

Last Updated: 2025-11-26

Results Overview

MRD-negative CR was achieved when a participant met the criteria for both MRD negativity and CR. MRD-negativity: ≤0.01 % breakpoint cluster region-Abelson (BCR-ABL1/ABL1), or undetectable BCR-ABL1 transcripts in complementary deoxyribonucleic acid (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 less than (\<) 5% blasts in the bone marrow (BM). 2. Normal maturation of all cellular components in the BM. 3. No extramedullary disease (central nervous system \[CNS\] involvement, lymphadenopathy, splenomegaly, skin/gum infiltration, testicular mass). 4. Absolute neutrophil count (ANC) \> 1000 per microliter (/mcL) (or \>1.0\*10\^9/L). 5. Platelets \>100,000/mcL (or \>100\*10\^9/L).

Population: ITT population with p190/p210 variant was defined as all participants in the ITT population who were identified by the central laboratory as having baseline breakpoint cluster region-Abelson1 (BCR-ABL1) dominant variants of p190 or p210.

MRD-negative CR was achieved when a participant met the criteria for both MRD negativity and CR. MRD-negativity: ≤0.01 % breakpoint cluster region-Abelson (BCR-ABL1/ABL1), or undetectable BCR-ABL1 transcripts in complementary deoxyribonucleic acid (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 less than (\<) 5% blasts in the bone marrow (BM). 2. Normal maturation of all cellular components in the BM. 3. No extramedullary disease (central nervous system \[CNS\] involvement, lymphadenopathy, splenomegaly, skin/gum infiltration, testicular mass). 4.

MRD is defined as the percentage of participants achieving CR who are MRD-negative at multiple intervals after end of induction. MRD negativity: \<=0.01% BCR-ABL1/ABL1, or undetectable BCR-ABL1 transcripts in cDNA with \>=10,000 ABL1 transcripts. Relapse from CR: Reappearance of blasts in the blood or BM (\>=5%) or in any extramedullary site after a CR.

SECONDARY outcome

Timeframe: Up 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.

Timeframe: Up to approximately 6 years

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.

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.
