On Day 1 of Cycle 3 and then every 3 cycles after that (Cycles 6, 9, 12, and so on) (+/- 14 days), blood (about 2-3 tablespoons) will be drawn for routine tests. Participant may choose to have these blood draws performed at a local lab or clinic closer to their home. The results of this testing will then be sent to the study doctor at MD Anderson. The study doctor will discuss this option with participant.
