What was measured
CrkL is a protein, phosphorylation of which has been shown to correlate with CML cell growth; and conversely inhibition of their phosphorylation correlates with inhibition of tumor cell growth. Phosphorylation of CrkL was monitored in whole blood cells, as well as in the cluster of differentiation 3 (CD3+) (T cell), CD19+ (B cell) and CD34+ (blast cell) compartments by using fluorescent activated cell sorter (FACS) flow cytometry.
Analysis population: Evaluable population included all enrolled participants who received at least 1 dose of study medication and had an adequate baseline efficacy assessment. 'N' (number of participants analyzed) signifies number of participants who were evaluable for this measure.
Groups in this outcome
Bosutinib 400 mg (Part 1)
Single oral dose of bosutinib 400 mg on Day 1 and then bosutinib 400 mg orally once daily continuously from Day 3 up to Week 4. All participants who completed treatment in Part 1 were continued in CP2L-CML Part 2 of the study.
Bosutinib 500 mg (Part 1)
Single oral dose of bosutinib 500 mg on Day 1 and then bosutinib 500 mg orally once daily continuously from Day 3 up to Week 4. All participants who completed treatment in Part 1 were continued in CP2L-CML Part 2 of the study.
Bosutinib 600 mg (Part 1)
Single oral dose of bosutinib 600 mg on Day 1 and then bosutinib 600 mg orally once daily continuously from Day 3 up to Week 4. All participants who completed treatment in Part 1 were continued in CP2L-CML Part 2 of the study. Eleven participants who completed treatment in Part 1 were continued in CP2L-CML Part 2 of the study and 1 participant was continued in AP-CML Part 2 of the study.
