The study treatments will be administered every three weeks, (which is considered a study treatment cycle), until you complete six treatment cycles, the tumor grows, disappears, or you experience a side effect, which may cause you to leave the study. Follow-up visits will occur on Days 3, 10, and 21 following treatment in the first cycle and Days 7 and 21 for the remaining cycles, and also 60 days after you receive your last treatment cycle.
