Time frame
From the date of first confirmed MaHR to date of progression, death, or last tumor assessment (maximum participant duration of response of 37 months).

What was measured

Duration of MaHR is the time (in months) from the first day criteria were met for MaHR, provided they were confirmed later at least after 28 days with no concomitant use of anagrelide or hydroxyurea during this interval, until death or progression was first observed. MaHR: Defined as participants having as best response a CHR or CHRp. Refer to outcome measure 20 for criteria for CHR or CHRp. The Kaplan-Meier plot was used. A 2-sided, 95% CI for the median was computed using the Brookmeyer and Crowley method.

Analysis population: All treated participants with MaHR in stratum 2/3. Participants who neither discontinued due to progression nor progressed nor died were censored on the date of their last hematologic or cytogenetic assessment, whichever came last.

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.
