What was measured

A participant is said to have a confirmed HR if criteria for HR were fulfilled again at least 28 days after they first met with no concomitant use of anagrelide or hydroxyurea during this interval. Confirmed HR observed in stratum 2/3 was either CHR or MaHR or overall hematologic response (OHR). Refer to Outcome Measure 19 for criteria for CHR and MaHR. OHR is defined as MaHR or MiHR. MiHR=CHRp except blasts in BM (≥ 5% and ≤ 15% blasts in BM). The Clopper and Pearson method was used to compute 95% exact CIs.

Analysis population: All treated participants in stratum 2/3: Participants who received at least 1 dose of dasatinib 80 mg/m\^2.

Groups in this outcome

Stratum 2/3 Ph+ ALL or AP/BP-CML (Dasatinib 80 mg/m^2)

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). Dasatinib 80 mg/m\^2 QD, as long as clinical benefit was maintained.
