Clinical Trial Summary

The purpose of this study is to compare the efficacy and safety of 2 starting doses of ponatinib compared to nilotinib in participants with imatinib-resistant chronic myeloid leukemia (CML) in chronic phase (CP).


Description:

This is a multi-center, randomized study to demonstrate the efficacy and safety of 2 starting doses of ponatinib as a treatment for CP-CML compared to nilotinib. Eligible participants must have chronic phase chronic myeloid leukemia (CP-CML), be resistant to first-line imatinib treatment and have received no other tyrosine kinase inhibitors (TKIs).

Outcome

Type Measure Description Time frame Safety issue
Primary Percentage of Participants With Major Molecular Response (MMR) MMR is defined as the percentage of participants achieving a ratio of =0.1% Breakpoint Cluster Region-Abelson (BCR ABL) to ABL transcripts on the international scale (=0.1% BCR-ABL/ABL[IS]) at any time within 12 months after randomization. Up to 12 months
Secondary Percentage of Participants With Major Cytogenetic Response (MCyR) MCyR was the percentage of participants achieving Complete cytogenetic response (CCyR: defined as 0% Philadelphia chromosome-positive [Ph+] metaphases by cytogenetic analysis of bone marrow) or Partial Cytogenetic Response (PCyR: defined as >0% to 35% Ph+ metaphases by cytogenetic analysis of bone marrow) at any time within 12 months after randomization. Up to 12 months
Secondary Percentage of Participants With Complete Cytogenetic Response (CCyR) CCyR rate was defined as the percentage of participants achieving CCyR up to 12 months after randomization. CCyR is defined as 0% Philadelphia chromosome-positive [Ph+] metaphases by cytogenetic analysis of bone marrow. Up to 12 months
Secondary Percentage of Participants With Molecular Response (MR) Molecular response rate is defined as percentage of participants achieving MR2: Molecular response with 2-log reduction (defined as =1% BCR-ABL[IS]), MMR: Major molecular responder, MR4 (defined as =0.01% BCR-ABL[IS]), and MR4.5 (defined as =0.0032% BCR-ABL[IS]) after randomization. From Month 3 to every 3 months up to 48 months
Secondary Percentage of Participants With MR1 MR1 was defined as the percentage of participants achieving a ratio of =10% BCR ABL to ABL transcripts on the international scale at 3 months. Month 3
Secondary Percentage of Participants With Treatment Emergent Arterial Occlusive Events (TE-AOEs), Treatment Emergent Venous Thromboembolic Events (TE-VTE), Adverse Events (AEs), and Serious AEs (SAEs) TE-AOE: arterial occlusive event with an initial onset date on or after first dose date and no later than 30 days after last dose date of study treatment or events starting after initial consent that worsen in severity on or after first dose date. TE-VTE: vascular occlusive event with an initial onset date on or after first dose date and no later than 30 days after last dose date of study treatment or events starting after initial consent that worsen in severity on or after first dose date. AE: any untoward medical occurrence in participant administered pharmaceutical product; untoward medical occurrence does not necessarily have causal relationship with this treatment. SAE: any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalization or prolongation of an existing hospitalization, results in persistent or significant disability or incapacity, is congenital anomaly/birth defect/is medically important event. From first dose up to 30 days post last dose (Up to approximately 46 months)
Secondary Time to Response Time to MMR defined as the interval between the randomization date and the first date at which the criteria for response was met. MMR was defined as <=0.1% BCR-ABL. Up to approximately 60 months
Secondary Duration of Response Duration of response defined as the interval between the first assessment at which the criteria for response was met until the earliest date at which loss of response occurs, or the criteria for progression was met. Up to approximately 60 months
Secondary Progression-free Survival (PFS) Progression-free survival (PFS) defined as the interval between the first dose date of study treatment and the first date at which the criteria for progression was met (progression to AP- or BP CML), or death due to any cause, censored at the last response assessment. Up to end of study (approximately 60 months)
Secondary Overall Survival Overall survival (OS) defined as the interval between the first dose date of study treatment and date of death due to any cause, censored at the last contact date to be alive. Up to end of study (approximately 60 months)
Secondary Percentage of Participants Who Achieved/Maintained Complete Hematologic Response (CHR) CHR rate is defined as the percentage of participants achieving CHR at any time after initiation of study treatment. CHR is defined as achieving all of the following measurements: White blood cells (WBC) = institutional upper limit of normal (ULN); Platelets <450 x 10^9/L; No blasts or promyelocytes in peripheral blood; <5% myelocytes plus metamyelocytes in peripheral blood; Basophils in peripheral blood <5%; No extramedullary involvement (including no hepatomegaly or splenomegaly). 3 months after the first dose of study treatment
Secondary Percentage of Participants With Treatment Emergent AEs Leading to Treatment Discontinuation, Dose Reduction and Dose Interruption An AE is defined as any untoward medical occurrence in a clinical investigation participant administered a drug; it does not necessarily have to have a causal relationship with this treatment. A TEAE is defined as an adverse event with an onset that occurs after receiving study drug. From first dose up to end of treatment (Up to approximately 45 months)
Secondary Percentage of Participants With Progression to Accelerated Phase (AP) or Blast Phase (BP)-CML Progression to AP is defined as: >=15% and <30% blasts in peripheral blood or bone marrow or >=20% basophils in peripheral blood or bone marrow or >=30% blasts + promyelocytes in peripheral blood or bone marrow (but <30% blasts) or <100*10^9 platelets/L in peripheral blood unrelated to therapy or cytogenetic, genetic evidence of clonal evolution, and no extramedullary disease. Progression to BP-CML is defined as: >=30% blasts in peripheral blood or bone marrow or extramedullary disease other than hepatosplenomegaly. Up to end of study (Up to approximately 60 months)
