The data shown include only the first cohort of patients accrued to allow determination of the MTD and DLTs and do not include delays in the 11 patients added at 1.30 mg/m2 for further experience. Dose delays occurring in any cycle are shown.
The fraction shown is the number of unique cycles delayed/total number of cycles given to all patients at this dose level.
