Detailed Description
In the Dose Escalation Phase, patients will be assigned to one of three schedules. The MTD for all schedules will be determined from the assessment of Dose Limiting Toxicities (DLTs). The Dose Expansion Phase will consist of one cohort based on patients response to prior therapy according to the MTD selected.
