Maximally tolerated dose (MTD), determined according to dose-limiting toxicities (DLTs) graded using Common Terminology Criteria for Adverse Events version 3.0 (CTCAE v3.0) Up to 24 weeks [clinicaltrials_resource:96a85e705f8124fae3b9b3e26c40efc1]

Simple summary statistics will be supplemented with Kaplan-Meier survival estimates and related confidence intervals.The effect of dose and ancillary dichotomized covariates such as gender or age (<50 years versus 50+ years) will be explored using logrank testing involving one covariate at a time.
