What was measured

A DLT was defined as any one of the following events: prolonged myelosuppression (as defined by the National Cancer Institute \[NCI\] criteria specific for leukemia, i.e., marrow cellularity \< 5% at ≥ 6 weeks from start of therapy without evidence of leukemia); ≥ Grade 3 non-hematologic toxicity (excluding Grade 3 nausea, vomiting or diarrhea that is adequately controlled with supportive care and resolves to ≤ Grade 2 within 48 hours, or Grade 3 electrolyte disturbances responsive to correction within 24 hours); ≥ Grade 3 liver function tests (LFTs) lasting \> 7 days; treatment interruption \> 14 days due to toxicity; or other important medical event. DLTs were collected to determine the MTD which is defined as the dose level below the dose at which ≥ 2 of 6 patients in a dose cohort experienced a DLT.

Analysis population: Full analysis set (FAS): All subjects who were administered any fraction of a dose of study medication.
