The MTD will be defined as the highest tested dose level at which =6 participants have been treated and which is associated with a Cycle 1 DLT in =17% of the participants.	Cycle 1 (Up to 21 Days)
Primary	Recommended Dosing Regimen (RDR)	Selection of the RDR will be based on consideration of short- and long-term safety information together with available pharmacokinetic, pharmacodynamic, and efficacy data. The RDR may be the MTD or may be a lower dose within the tolerable dose range.	Cycle 1 (Up to 21 Days)
