Brief Summary:
The purpose of this study is to test the hypothesis that patients with CML who have not achieved optimal response after 3 months of treatment with imatinib will have a better response by switching to dasatinib compared to staying on their original imatinib regimen.

Condition or disease Intervention/treatment Phase
Chronic Phase Chronic Myeloid Leukemia Drug: Imatinib Drug: Dasatinib Phase 2

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 262 participants
Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: An Open Label, Randomized (2:1) Phase IIb Study of Dasatinib Versus Imatinib in Patients With Chronic Phase Chronic Myeloid Leukemia Who Have Not Achieved an Optimal Response to 3 Months of Therapy With 400 mg Imatinib
Actual Study Start Date : October 29, 2012
Actual Primary Completion Date : November 8, 2017
Estimated Study Completion Date : February 17, 2022


Arm Intervention/treatment
Active Comparator: Arm 1: Imatinib (≥400 mg)
Imatinib ≥400 mg tablets by mouth once daily (QD) or twice daily (BID) up to 60 months
Drug: Imatinib
Other Names:
  • Gleevec
  • Glivec

Active Comparator: Arm 2: Dasatinib (100 mg)
Dasatinib 100 mg tablet by mouth QD up to 60 months
Drug: Dasatinib
Other Name: Sprycel




Primary Outcome Measures :
  1. Percentage of Patients Achieving Major Molecular Response (MMR) After 12 Months of CML Treatment [ Time Frame: At 12 months after Day 1 initiation of 1st line treatment with imatinib or imatinib at any dose, after less than optimal response to first-line imatinib. ]

    Major Molecular Response, is defined as a 3-log reduction in BCR-ABL transcripts from the standardized baseline, which represents 100% on the international scale, so a 3-log reduction is fixed at 0.1% for MMR; N/A = not applicable. 95% CI is Clopper-Pearson(Exact) two-sided 95% confidence intervals.

    P-value is based on Cochran-Mantel-Haenszel (CMH) test stratified by Sokal score(high, intermediate, low, and unknown) and time between 3 month molecular analysis and randomization (<=4 weeks vs >4 weeks). Month 12 is calculated fro



Secondary Outcome Measures :
  1. Median Time to Major Molecular Response (MMR) [ Time Frame: Up to 10 years ]
    Time to MMR is how fast patients achieve optimal response. It is the time between randomization date and first date that MMR criteria are satisfied.

  2. Time to Molecular Response (MR)^4.5 [ Time Frame: Up to 10 years ]
    Time to MR^4.5 is how fast patients achieve a deeper response. It is the time between randomization date and first date that MR^4.5 criteria are satisfied.

  3. Progression Free Survival (PFS) [ Time Frame: Up to 10 years ]
    PFS is how long patients are likely to live without progression of their disease. It is the time from randomization date to progression date or death date, whichever occurs first.

  4. Overall Survival (OS) [ Time Frame: Up to 10 years ]
    OS is how long patients are likely to remain alive. It is the time from randomization date to death date.

Criteria

For more information regarding BMS clinical trial participation, please visit www.BMSStudyConnect.com.

Inclusion Criteria:

  • Chronic Phase (CP)-CML Ph+ patients with complete hematologic response (CHR) but without one log BCR-ABL reduction (BCR-ABL level >10% IS) 3 months of imatinib 400mg treatment. (Imatinib transient dose adjustments due to Adverse Event (AEs) are allowed with a maximum of 2 weeks interruption of treatment with imatinib (cumulative) within the 3 month period before randomization). Imatinib monotherapy must have been started within 6 months of CP-CML diagnosis (Ph + /BCR-ABL detection)
  • Currently tolerating imatinib 400mg QD. Patients with prior imatinib treatment interruption or dose reductions are required to be on treatment with 400 mg imatinib for two weeks immediately prior to randomization to ensure tolerance to imatinib
  • Eastern Co-Operative Group (ECOG) performance status = 0 - 2
  • Adequate renal function defined as serum creatinine ≤3 times the institutional upper limit of normal (ULN)
  • Adequate hepatic function defined as: total bilirubin ≤2.0 times the institutional ULN; alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤2.5 times the institutional ULN

Exclusion Criteria:

  • Previous diagnosis of accelerated phase or blast crisis
  • Subjects with clonal evolution in Ph+ cells observed in ≥2 metaphases at baseline bone marrow cytogenetic test, unless the same abnormalities were present at diagnosis. Patients with no evidence of clonal evolution, including those patients whose cytogenetic testing fails or bone marrow aspiration is a dry tap at 3 months, are eligible for the study
  • Subjects with less than CHR after 3 months of imatinib treatment or lost CHR after initial achievement
  • Documented T315I/A, F317L, or V299L mutations (if already available - not required for screening)
  • A serious uncontrolled medical disorder or active infection that would impair the ability of the subject to receive protocol therapy
