Study Endpoints
Primary Endpoints
Safety and Tolerability of Fostamatinib
First cycle (28 days) of treatment

The number of dose limiting toxicities (DLTs) at each dose level will be reported. All toxicities will be reported by type and grade using NCI CTCAE version 4.03.

Maximum Tolerated Dose (MTD) of Fostamatinib
28 days

The MTD will be determined as the dose level with the highest probability of having a risk of DLT in the acceptable region based on the mTPI dose-escalation design. Measured at 28 days (DLT period).
