Design outcomes

Primary

MeasureTime frame
Part A: Randomized Controlled Arms: To compare the major molecular response (MMR) rate at 24 weeks of olverembatinib versus bosutinib Part B: Single Arm: To evaluate the MMR rate by 24 weeks of olverembatinib in CML-CP patients with T315I mutationTimepoint: 24 weeks

Secondary

MeasureTime frame
Part A: Randomized Controlled Arms: To compare the MMR rate at 96 weeks of olverembatinib versus bosutinib Part B: Single Arm: To evaluate the MMR rate by 96 weeks of olverembatinib in CML-CP patients with T315I mutationTimepoint: 96 weeks;Part A: Randomized Controlled Arms Other Secondary Objectives 1 To compare additional efficacy parameters of olverembatinib versus bosutinib 2 To compare the safety profile of olverembatinib versus bosutinib 3 To characterize the population pharmacokinetics (Pop PK) of olverembatinib in the CML-CP population 4 To evaluate Patient-Reported Outcome (PRO) measures of olverembatinib vs. bosutinib based on Europol 5 Dimension (EQ-5D). 5 To evaluate Health Economics Outcomes Research (HEOR) measures of olverembatinib vs. bosutinib based on EORTC QLQ-C30. Timepoint: 4 weeks & 8 weeks;Part B: Single Arm Other Secondary Objectives 1 To evaluate additional efficacy parameters of olverembatinib in CML-CP patients with T315I mutation 2 To evaluate the safety profile of olverembatinib in CML-CP patients with T315I mutation 3 To characterize the population PK of olverembatinib in the CML-CP population with T315I mutation 4 To evaluate patient-reported outcomes (PRO) measures of olverembatinib using Europol 5 Dimension (EQ-5D) 5 To evaluate Health Economics Outcomes Research (HEOR) measures of olverembatinib based on EORTC QLQ-C30. Timepoint: 4 weeks & 8 weeks
