Title:
Dasatinib in the Treatment of Chronic Myeloid Leukemia in Accelerated Phase After Imatinib Failure: The START A Trial
Excerpt:
Patients with imatinib-resistant (n = 161) or -intolerant (n = 13) CML-AP received dasatinib 70 mg orally twice daily. The number of patients with BCR-ABL mutations before study treatment was 88 (56%) of 156, and 29 different mutations were detected. As noted previously,17 patients with a preexisting T315I mutation (n = 9) did not respond to dasatinib therapy (Table 3). Few CCyRs were observed in patients with F317L (0 of four) or E255K (one of eight) mutations.

Title:
Dasatinib induces significant hematologic and cytogenetic responses in patients with imatinib-resistant or -intolerant chronic myeloid leukemia in accelerated phase
Excerpt:
Mutations were identified in 60 (60%) of these patients (all with imatinib-resistant CML-AP). Despite the presence of imatinib-resistant BCR-ABL mutations and their association with poor prognosis, at 8 months' follow-up, 73% of patients with an imatinib-resistant BCR-ABL mutation had achieved MaHR following treatment with dasatinib.
