SECONDARY outcome

Timeframe: After core treatment period of 8 cycles (each cycle is 21 days)

The primary safety analysis will be based on subjects who experienced toxicities as defined by the current National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE, v4.0; Section 11.2). The attribution to drug, time-of-onset, duration of the event, its resolution, and any concomitant medications administered will be recorded.
