E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to estimate the major cytogenetic response (MCyR) rate to BMS-354825 in subjects with Philadelphia chromosome positive chronic phase Ph+ CML who have disease that is resistant to high dose imatinib (primary resistance, acquired resistance or mutation highly associated with imatinib resistance). |
|
E.2.2 | Secondary objectives of the trial |
1) To estimate the MCyR rate in the imatinib-intolerant subjects. 2) To assess the durability of MCyR and time to MCyR in the imatinib-resistant and the imatinib-intolerant groups 3) To estimate complete hematologic response (CHR) rate, duration of CHR and time to CHR in the imatinib-resistant and the imatinib-intolerant groups 4) To estimate major molecular response rate in the imatinib-resistant and the imatinib-intolerant groups 5) To assess the health-related quality of life using the FACT-G 6) To assess further the safety and tolerability of BMS-354825 7) To collect blood samples for pharmacokinetic analysis of BMS-354825 given BID that will contribute to population pharmacokinetic modeling. |

1) Available for periodic follow-up 2) Life expectancy of at least approximately 3 months 3) ECOG performance status score 0-1 4) Subjects with chronic phase Ph+ CML, defined as a myeloproliferative disorder with evidence of a Philadelphia chromosome on cytogenetic analysis. Subjects meeting all of the following criteria will be classified as having chronic phase CML: • < 15% blasts in peripheral blood and in bone marrow • < 20% basophils in peripheral blood • < 30% blasts + promyelocytes in peripheral blood and in bone marrow • Platelets ≥ 100,000/mm3 unless thrombocytopenia is due to recent therapy • No extramedullary involvement (other than liver or spleen) 5) Subjects must fulfill at least one of the following criteria relating to prior treatment with imatinib: A. Previously been treated with imatinib at a dose of > 600 mg/day AND developed progressive disease while receiving imatinib at that dose. B. CML with resistance to imatinib ≤600 mg/d with genetic mutation in the BCR-ABL gene that is associated with a high level of resistance to imatinib. C. Intolerant of imatinib at any dose. 6) Adequate hepatic function defined as: • total bilirubin ≤ 2.0 times the institutional upper limit of normal • alanine aminotransferase (ALT) and aspartate aminotransferase (AST) ≤ 2.5 times the institutional upper limit of normal 7) Adequate renal function defined as: • serum creatinine ≤ 1.5 times the institutional upper normal limit 8) Serum potassium and magnesium levels within institutional normal limits. Total serum calcium or ionized calcium level must be greater than or equal to the lower limit of normal. 9) Men and women, ages 18 years of age or older.

E.5 End points |
E.5.1 | Primary end point(s) |
Efficacy:
The primary endpoint of this Phase II study is to estimate MCyR rate to BMS- 354825 in treated subjects with chronic phase Ph+ CML who have resistance to high dose imatinib (primary resistance, acquired resistance or mutation highly associated with imatinib resistance).
Secondary endpoints include duration of MCyR, time to MCyR, complete hematologic response (CHR) rate, duration of CHR, time to CHR, major molecular response rate and BCR/ABL mutational analysis, in addition to health-related quality of life, safety and collection of samples to contribute to population pharmacokinetic modeling. A separate calculation of response rates will be performed for the imatinib-intolerant group at the time of the primary analysis for the imatinib-resistant subjects.
Safety:
Evaluation of safety will be a secondary endpoint of this study. For safety evaluation, toxic effects will be assessed continuously. All subjects who receive any study drug will be evaluable for toxicity. Adverse events and other symptoms will be graded according to the NCI Common Terminology Criteria for Adverse Events (CTCAE) Version 3.0.
The criteria for all the primary and secondary endpoints are defined in Protocol Section 3.3. |
