ANC, absolute neutrophil count; Hgb, hemoglobin; WBC, white blood cell.

*

Excluding the provisional entities of AML with NPM1 and AML with CEBPA mutation (molecular data not available).

Per central review.

Patients were randomly assigned on the basis of local pathology assessment of baseline BM blast count, which was subsequently reviewed by the central pathologist; in a small number of cases, baseline blast count was <30% upon central review.

§

Per modified NCCN Clinical Practice Guidelines, 2010 (1 azacitidine patient and 2 CCR patients were missing cytogenetic data).

||

In some cases, maximum WBC values were higher than protocol exclusion criteria (WBC value of ≤15 × 109/L). Values shown here are the last nonmissing value before randomization, which may have been obtained after the screening WBC value used for study entry.
