The primary purpose of this study is to find the highest tolerated dose of the study drugs: capecitabine, oxaliplatin, bevacizumab, and dasatinib given in combination to subjects with advanced solid tumors. This will occur in the first part of the study (Phase I). Once this dose has been determined, it will be given to subjects with advanced metastatic colorectal cancer in the second part of the study (Phase II).
