PN401 permits treatment with higher than normal doses of 5FU, which could increase its therapeutic potential. It is hypothesized that adding PN401 to the CPT-11, 5FU, leucovorin regimen will reduce toxicity and will allow higher doses of 5FU to be well tolerated and therefore potentially increase effectiveness.2002-08-152008163NCT00044785
