I don't know anything about that particular study, but my husband was on Avastin/5Fu/Leucovorin/Oxaliplatin for 3 months this summer. In August, they took him off of it for 4 weeks, then tried a chemoembollism and it failed. The blood vessels were so small they couldn't get the dye injected into them. Because the tumors weren't responding, we switched to Erbitux and CPT11 the beginning of September and he's doing well. His lung mets have virtually disappeared and the liver ones are shrinking. He's tolerating this chemo a lot better too.
Hope this helps,
