This study will use a dose escalation design to determine the MTD of CGC-11047 when used in individual combinations with gemcitabine, or docetaxel, or bevacizumab, or erlotinib or cisplatin or 5-flurouracil or sunitinib in one of 7 treatment arms. The dose of CGC-11047 will be escalated in cohorts of 3 patients and dose escalation can proceed in each treatment group independent of dose escalation in the other treatment groups. CGC-11047 will be administered IV over 60 minutes and the doses of gemcitabine, docetaxel, bevacizumab, cisplatin, 5-flurouracil or sunitinib will remain fixed according to their respective product labeling.
