  Purpose

This is an open-label, continuous daily dosing, two-part safety and efficacy study of SKI-606 (bosutinib) in Philadelphia chromosome positive leukemias (Ph+). Part 1 is a dose-escalation study in chronic phase Chronic Myelogenous Leukemia (CML) subjects to establish the maximum tolerated dose (MTD) in this subject population. Part 2 has begun after the completion of Part 1 and after a dose has been established for the compound in chronic phase subjects. Part 2 is a study of the the efficacy of 500mg daily oral SKI-606 (bosutinib) in patients with all phases of Ph+ CML and Ph+ Acute Lymphocytic Leukemia (ALL). The protocol will test the hypotheses that oral daily dosing of bosutinib at 500 mg will attain (1) Major Cytogenetic Response (MCyR) in chronic phase CML patients and (2) Overall Hematological Response (OHR) in advanced leukemia patients. Each phase of the disease will be evaluated as a separate cohort.

Primary Outcome Measures:
  • Number of Participants With Dose Limiting Toxicity (DLT) [ Time Frame: Part 1 Baseline up to Day 28 ] [ Designated as safety issue: Yes ]
    DLT was defined as any of the following events occurring during the first 28 days of study medication and considered at least possibly-related to study medication: any grade 3 or 4 clinically-relevant non-hematologic toxicity, any clinically-significant grade 2 non-hematologic toxicity that requires 14 days to resolve (to grade 1).

  • Maximum Tolerated Dose (MTD) [ Time Frame: Part 1 Baseline up to Day 28 ] [ Designated as safety issue: Yes ]
    MTD was defined as highest dose level for which no more than 1 participant in a dose cohort experienced DLT. DLT was defined as any of the following events occurring during the first 28 days of study medication and considered at least possibly-related to study medication: any grade 3 or 4 clinically-relevant non-hematologic toxicity, any clinically-significant grade 2 non-hematologic toxicity that requires 14 days to resolve (to grade 1).

  • Maximum Observed Plasma Concentration (Cmax) - Part 1 [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 6, 8, 24, 48 hours post-dose on Day 1 ] [ Designated as safety issue: No ]
  • Time to Reach Maximum Observed Plasma Concentration (Tmax) - Part 1 [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 6, 8, 24, 48 hours post-dose on Day 1 ] [ Designated as safety issue: No ]
  • Plasma Decay Half-Life (t1/2) - Part 1 [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 6, 8, 24, 48 hours post-dose on Day 1 ] [ Designated as safety issue: No ]
    Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

  • Area Under the Curve From Time Zero to Last Quantifiable Concentration (AUClast) - Part 1 [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 6, 8, 24, 48 hours post-dose on Day 1 ] [ Designated as safety issue: No ]
    Area under the plasma concentration time-curve from zero to the last measured concentration (AUClast).

    AUC is a measure of the serum concentration of the drug over time. It is used to characterize drug absorption. There were fewer participants evaluable for AUC values than participants evaluable for AUClast because terminal half-life of some participants was not accurately estimated and therefore AUC in these participants was not calculated.

    Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood.

  • Apparent Volume of Distribution (Vz/F) - Part 1 [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 6, 8, 24, 48 hours post-dose on Day 1 ] [ Designated as safety issue: No ]
    Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug. Apparent volume of distribution after oral dose (Vz/F) is influenced by the fraction absorbed.

    Time to reach maximum observed plasma concentration over 24 hours at steady state (ss), on Day 15.

  • Plasma Decay Half-Life at Steady State (t1/2,ss) - Part 1 [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 6, 8, 24 hours post-dose on Day 15 ] [ Designated as safety issue: No ]
    Plasma decay half-life is the time measured for the plasma concentration to decrease by one half. Plasma decay half-life over 24 hours at steady state (ss), on Day 15 was calculated.

  • Area Under the Concentration-Time Curve at Steady State (AUCss) - Part 1 [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 6, 8, 24 hours post-dose on Day 15 ] [ Designated as safety issue: No ]
    AUC is a measure of the serum concentration of the drug over time. It is used to characterize drug absorption. AUC over 24 hours at steady state (ss), on Day 15 was calculated.

    Clearance of a drug is a measure of the rate at which a drug is metabolized or eliminated by normal biological processes. Clearance obtained after oral dose (apparent oral clearance) is influenced by the fraction of the dose absorbed. Drug clearance is a quantitative measure of the rate at which a drug substance is removed from the blood. Apparent oral clearance over 24 hours at steady state (ss), on Day 15 was calculated.

  • Accumulation Ratio (R) [ Time Frame: 0 (pre-dose), 1, 2, 3, 4, 6, 8, 24 hours post-dose on Day 1 and Day 15 ] [ Designated as safety issue: No ]

    Cytogenetic response (CyR) is based on the prevalence of Philadelphia positive (Ph+) cells. Major cytogenetic response was categorized as either complete cytogenetic response (CCyR) or partial cytogenetic response (PCyR). CCyR was achieved when there was 0 percent (%) Ph+ cells and PCyR was achieved when 1 to 35% Ph+ cells.

    Data for this Outcome Measure are not reported here because the analysis population includes participants who were not enrolled in this study. ClinicalTrials.gov is designed for reporting results from only those participants who were enrolled in the study and described in the Participant Flow and Baseline Characteristics modules.
