Results Overview

MaHR=best confirmed response of complete hematologic response (CHR) or No Evidence of Leukemia (NEL). Criteria for MaHR are specified in Outcome Measure 2. OHR=best confirmed response of MaHR or minor HR (MiHR). MiHR= \<15% blasts in bone marrow and \<15% blasts in peripheral blood (PB); \<30% blasts + promyelocytes in bone marrow and \<30% blasts + promyelocytes in PB; \<20% basophils in PB; no extramedullary disease other than spleen and liver. Confirmed hematologic response=response confirmed ≥4 weeks after first documented event with no concomitant use of anagrelide or hydroxyurea.

Measure
Imatinib-intolerant
Defined as: i) Toxicity that was considered at least possibly related to imatinib ≤400 mg/day that led to a discontinuation of imatinib therapy ii) Ability to tolerate only \<400 mg/day imatinib. A subject who tolerated 400 mg/day imatinib, but was intolerant of higher doses was not considered imatinib-intolerant. Receiving oral dasatinib at a starting dose of 70 mg twice daily (BID), with dose modifications as necessary for the management of disease progression or toxicity.
Imatinib-resistant
Defined as any of the following: i) Subjects initially diagnosed with chronic phase chronic myeloid leukemia (CML) who progressed to myeloid phase CML while on treatment with a prescribed imatinib dose of ≥400 mg/day. ii) Subjects initially diagnosed with accelerated phase CML who progressed to myeloid phase CML while on treatment with a prescribed imatinib dose of ≥600 mg/day (or 400 to \<600 mg/day if subject is intolerant of ≥600 mg/day). iii) Subjects initially diagnosed with myeloid blast phase CML who meet the criteria for myeloid phase blast crisis after at least 4 weeks of treatment prescribed at a dose of ≥600 mg/day (or 400 to \<600 mg/day if subject is intolerant of ≥600 mg/day). Each of these definitions includes subjects who had no response to imatinib (primary resistance) and those who responded and subsequently progressed to myeloid blast phase (acquired resistance). Oral dasatinib 70 mg BID, with dose modifications as necessary to manage disease progression or toxicity.

Number of participants who achieved an MMR at any time during the treatment period. MMR was calulated by measuring BCR-ABL transcripts in blood during treatment using quantitative reverse transcription-polymerase chain reaction (RT-PCR). BCR-ABL=the fused gene found in subjects with this type of Chronic Myeloid Leukemia (CML).

Timeframe: baseline, at time of disease progression

Population: All subjects with baseline mutation data; n=the number of participants with the specified mutation. Baseline mutation data were reported for 103 of the 109 subjects (10/10 imatinib-intolerant and 93/99 imatinib-resistant). At baseline, 39 (42%) imatinib-resistant subjects and 3 imatinib-intolerant subject had imatinib-resistant mutations

MaHR and MCyR in subjects with mutations at baseline, including imatinib-resistant mutations (IRM) and specific BCR-ABL mutations (SBAM). Criteria for MaHR are specified in Outcome Measure 2. MCyR=rate of complete cytogenetic responses + the rate of partial cytogenetic responses, as defined in Outcome Measure 5. BCR-ABL=the fused gene found in subjects with this type of CML. This table contains those mutations observed in at least 3 participants. The categories "1 IRM w/2-4-fold increase in resistance" and "≥1 IRM w/≥5-fold increase in resistance" refer to increase in resistance to imatinib.

Timeframe: Collected on Days 1 and 8 at times as close as possible to the following time points (relative to drug administration): pre-dose, and following drug administration at 30 minutes, 1 hour, 1.5, 2, 3, 4, 5, 6, 8 and 10 hours.

Population: 26 participants had dense PK sampling on Day 1 and Day 8; parameters for 1 participant on Day 8 was excluded due to unreliable data. Participants with all concentration-time values \< than the limit of quantitation were treated as missing for PK analysis. n= participants included in the statistical analyses of PK on Day 1 and Day 8, respectively.

The Cmax was obtained from experimental observations. Using no weighting factor, the terminal log-linear phase of the concentration-time curve was identified by least-square linear regression of at least 3 data points that yielded a maximum G-criteria,which is also referred to as adjusted R-squared.

Defined as any of the following: i) Subjects initially diagnosed with chronic phase chronic myeloid leukemia (CML) who progressed to myeloid phase CML while on treatment with a prescribed imatinib dose of ≥400 mg/day. ii) Subjects initially diagnosed with accelerated phase CML who progressed to myeloid phase CML while on treatment with a prescribed imatinib dose of ≥600 mg/day (or 400 to \<600 mg/day if subject is intolerant of ≥600 mg/day). iii) Subjects initially diagnosed with myeloid blast phase CML who meet the criteria for myeloid phase blast crisis after at least 4 weeks of treatment prescribed at a dose of ≥600 mg/day (or 400 to \<600 mg/day if subject is intolerant of ≥600 mg/day). Each of these definitions includes subjects who had no response to imatinib (primary resistance) and those who responded and subsequently progressed to myeloid blast phase (acquired resistance). Oral dasatinib 70 mg BID, with dose modifications as necessary to manage disease progression or toxicity.

Defined as: i) Toxicity that was considered at least possibly related to imatinib ≤400 mg/day that led to a discontinuation of imatinib therapy ii) Ability to tolerate only \<400 mg/day imatinib. A subject who tolerated 400 mg/day imatinib, but was intolerant of higher doses was not considered imatinib-intolerant. Receiving oral dasatinib at a starting dose of 70 mg twice daily (BID), with dose modifications as necessary for the management of disease progression or toxicity.
Imatinib-resistant
n=99 participants at risk
Defined as any of the following: i) Subjects initially diagnosed with chronic phase chronic myeloid leukemia (CML) who progressed to myeloid phase CML while on treatment with a prescribed imatinib dose of ≥400 mg/day. ii) Subjects initially diagnosed with accelerated phase CML who progressed to myeloid phase CML while on treatment with a prescribed imatinib dose of ≥600 mg/day (or 400 to \<600 mg/day if subject is intolerant of ≥600 mg/day). iii) Subjects initially diagnosed with myeloid blast phase CML who meet the criteria for myeloid phase blast crisis after at least 4 weeks of treatment prescribed at a dose of ≥600 mg/day (or 400 to \<600 mg/day if subject is intolerant of ≥600 mg/day). Each of these definitions includes subjects who had no response to imatinib (primary resistance) and those who responded and subsequently progressed to myeloid blast phase (acquired resistance).
