Time frame
Days 8, 15, 22, 29, 36, 43; Weeks 4, 7, 13, 19, 25, 31, 37; then every 12 weeks upto 24 months; then once/year; until confirmed MaHR (maximum participant time to first MaHR of 44 days).

What was measured

Defined as time (in days) from first dose of dasatinib until the first day MaHR criteria were met, provided they were confirmed later (after 28 days) with no concomitant use of anagrelide or hydroxyurea during this interval. MaHR: Defined as participants having as best response a CHR or CHRp. Refer to Outcome Measure 15 for criteria for CHR and CHRp. Estimated by the Kaplan-Meier method and a 2-sided, 95% CI for the median was computed using the Brookmeyer and Crowley method.

Analysis population: Treated participants with MaHR in stratum 2/3.

Groups in this outcome

Stratum2/3 Ph+ALL or AP/BP-CML;Dasatinib60mg/m^2 Starting Dose

Participants with imatinib-resistant or imatinib-intolerant Ph+ CML in accelerated phase (AP), or in myeloid blast phase (MBP), or in lymphoid blast phase (LBP); or relapsed or refractory Ph+ acute lymphoblastic leukemia (ALL) after imatinib use; or second or subsequent relapse of Ph+ acute myeloid leukemia (AML). Starting Dose Level of 60 mg/m\^2; Escalated/Dose level 2 of 80 mg/m\^2 QD, as long as clinical benefit was maintained.
