ClinConnect Summary

PRIMARY OBJECTIVES:

I. Determine the progression-free survival in patients with newly diagnosed metastatic colorectal cancer treated with modified fluorouracil, leucovorin calcium, and oxaliplatin 6 (mFOLFOX6)/bevacizumab and PRI-724 vs. mFOLFOX6/bevacizumab alone.

SECONDARY OBJECTIVES:

I. Overall survival, defined as period from time of randomization to death. II. Response rate. III. Determine the incidence and severity of adverse events of PRI-724 administered as a 7-day continuous infusion in patients treated with mFOLFOX6/bevacizumab and PRI-724.

IV. Determine messenger ribonucleic ...
