"What we found in this study is that our ratiometric dosing formulation of irinotecan and floxuridine achieved the targeted 1:1 molar ratio that provided synergistic benefits to all patients including those who had been treated previously with irinotecan. Based on these findings, Celator is moving forward with a Phase 2 study for CPX-1 that includes treatment of irinotecan- naïve patients as well as patients who are resistant or refractory to irinotecan," said Arthur Louie, M.D., Celator's chief medical officer.

The ongoing phase 2 study for CPX-1 involves patients with colorectal cancer who will be treated at sites in the U.S. and Canada. For information, visit: www.clinicaltrials.gov/ct/show/NCT00361842?order=1.
