Study Status: Completed
Recruit Status: Completed
Study Type: Interventional

Official Title: A Randomized Two-Arm, Multicenter, Open-Label Phase III Study of BMS-354825 Administered Orally at a Dose of 70 mg Twice Daily or 140 mg Once Daily in Subjects With Chronic Myeloid Leukemia in Acceler

Brief Summary: This is a phase III study of BMS-354825 in subjects with chronic myelogenous leukemia in accelerated phase, or in myeloid or lymphoid blast phase or with Philadelphia chromosome positive (Ph+) acute lymphoblastic leukemia who are resistant or intolerant to imatinib mesylate (Gleevec).

Detailed Summary:
Sponsor: Bristol-Myers Squibb

Current Primary Outcome: Percent of Participants With Major Hematologic Response (MaHR) With 6 Months of Follow-up From Date of Last Enrollment - Randomized Population [ Time Frame: Randomization up to 6 months ]

MaHR defined by either complete hematologic response (CHR) or no evidence of leukemia (NEL). CHR defined as: white blood cells (WBC) ≤ upper limit of normal (ULN); absolute neutrophil count (ANC) ≥ 1,000/mm^3; platelets ≥ 100,000/mm^3; no blasts or promyelocytes in peripheral blood (PB); bone marrow (BM) blasts ≤ 5%; <5% myelocytes plus metamyelocytes in PB; basophils in PB < 20%; no extra-medullar involvement (including no hepatomegaly or splenomegaly). NEL defined by same criteria as CHR except that platelets and ANC had to satisfy at least one of the following (note that both lower limits had to be satisfied): platelets ≥ 20,000/mm^3 and < 100,000/mm^3; ANC > 500/mm^3 and <1,000/mm^3. After Year 2, Amendment 3 allowed participants to switch from the BID to the QD dosing schedule. Percentage: number of participants with MaHR/number of randomized participants.

Current Secondary Outcome:

  • Percent of Participants With Major Hematological Response (MaHR) With 2 Years of Follow-up From Date of Last Enrollment - Randomized Population [ Time Frame: Randomization up to 2 years ]
    A MaHR was defined as a participant having either CHR or NEL. CHR was defined as: WBC ≤ ULN; ANC ≥ 1,000/mm^3; - platelets ≥ 100,000/mm^3; - no blasts or promyelocytes in PB; BM blasts ≤ 5%; < 5% myelocytes plus metamyelocytes in PB; basophils in PB < 20%; no extra-medullar involvement (including no hepatomegaly or splenomegaly). NEL defined by the same criteria as CHR except that platelets and ANC had to satisfy at least one of the following (both lower limits had to be satisfied): platelets ≥ 20,000/mm^3 and < 100,000/mm^3; ANC > 500/mm^3 and <1,000/mm^3. After Year 2, Amendment 3 allowed participants to switch from the BID to the QD dosing schedule. Percent: number of participants with MaHR /number of participants randomized.
  • Percent of Participants With Major Hematologic Response (MaHR) by Disease Group - Randomized Population [ Time Frame: Randomization up to 2 years ]
    MaHR was defined by either complete hematologic response (CHR) or no evidence of leukemia (NEL). CHR defined as: white blood cells (WBC) ≤ upper limit of normal (ULN); absolute neutrophil count (ANC) ≥ 1,000/mm^3; platelets ≥ 100,000/mm^3; no blasts or promyelocytes in peripheral blood (PB); bone marrow (BM) blasts ≤ 5%; <5% myelocytes plus metamyelocytes in PB; basophils in PB < 20%; no extra-medullar involvement (including no hepatomegaly or splenomegaly). NEL defined by same criteria as CHR except that platelets and ANC had to satisfy at least one parameter of the following (note that both lower limits had to be satisfied): platelets ≥ 20,000/mm^3 and < 100,000/mm^3; ANC > 500/mm^3 and <1,000/mm^3. After Year 2, Amendment 3 allowed participants to switch from the BID to the QD dosing schedule.. Percentage: participants with MaHR/randomized participants.
  • Median Time to Major Hematologic Response (MaHR) - Randomized Population [ Time Frame: Day 1 up to 6 months (time of primary endpoint), 2 years ]
    A participants' time to MaHR was defined as the time from the first dosing date until criteria are first met for CHR or NEL, whichever occurred first. Non-responders were censored at the maximum of the date of last hematologic or cytogenetic assessment. Median time was measured in months.
  • Median Duration of a Major Hematologic Response (MaHR) in Those Participants Who Achieved a MaHR During the Study [ Time Frame: Day 1 up to 5 years ]
    MaHR was defined by either CHR or no evidence of leukemia NEL. CHR was defined as: WBC ≤ ULN; ANC ≥ 1,000/mm^3; - platelets ≥ 100,000/mm^3; - no blasts or promyelocytes in PB; BM blasts ≤ 5%; < 5% myelocytes plus metamyelocytes in PB; basophils in PB < 20%; no extra-medullar involvement (including no hepatomegaly or splenomegaly). NEL defined by the same criteria as CHR except that platelets and ANC had to satisfy at least one of the following (note that both lower limits had to be satisfied): platelets ≥ 20,000/mm^3 and < 100,000/mm^3; ANC > 500/mm^3 and <1,000/mm^3. Median duration was measured in months.
  • Percent of Participants With Overall Hematologic Response - Randomized Population [ Time Frame: Randomization up to 6 Months, 2 Years ]
    Overall Hematologic Response (OHR) was defined as CHR, NEL or minor hematologic response (MiHR). CHR was defined as: WBC ≤ ULN; ANC ≥ 1,000/mm^3; - platelets ≥ 100,000/mm^3; - no blasts or promyelocytes in PB; BM blasts ≤ 5%; < 5% myelocytes plus metamyelocytes in PB; basophils in PB < 20%; no extra-medullar involvement (including no hepatomegaly or splenomegaly). NEL defined by the same criteria as CHR except that platelets and ANC had to satisfy at least one of the following (note that both lower limits had to be satisfied): platelets ≥ 20,000/mm^3 and < 100,000/mm^3; ANC > 500/mm^3 and <1,000/mm^3. MiHR defined as: < 15% blasts in BM and in PB; < 30% blasts + promyelocytes in BM and PB; < 20% basophils in PB; No extra-medullary disease other than spleen and liver. Percentage: participants with OHR/ randomized participants.
  • Number of Participants With Best Confirmed Hematologic Response, Major Hematologic Response (MaHR) and Overall Hematologic Response - Randomized Population [ Time Frame: Randomization up to 6 months, 2 years ]
    Type of hematologic response: CHR defined as: WBC ≤ ULN; ANC ≥ 1,000/mm^3; - platelets ≥ 100,000/mm^3; - no blasts or promyelocytes in PB; BM blasts ≤ 5%; < 5% myelocytes plus metamyelocytes in PB; basophils in PB < 20%; no extra-medullar involvement (including no hepatomegaly or splenomegaly). NEL defined by the same criteria as CHR except that platelets and ANC had to satisfy at least one of the following (note that both lower limits had to be satisfied): platelets ≥ 20,000/mm^3 and <100,000/mm^3; ANC > 500/mm^3 and <1,000/mm^3. Minor Hematologic Response (MiHR): <15% blasts in BM and in PB; < 30% blasts + promyelocytes in BM and PB; < 20% basophils in PB; No extra-medullary disease other than spleen and liver. Major hematologic response (MaHR ) was CHR
