Study summary

The purpose of this study is to determine the clinical toxicities associated with administering sequential dFdC as a one hour infusion followed by a continuous infusion of FUdR over 24 hours with low dose oral LV weekly for three weeks out of four.

Read the detailed description

The MTD and biochemically active dose of FUDR as a 24-hour and gemcitabine as a 2-hour infusion will be determined first (Part A); if the biochemically active FUDR dose is less than the MTD, new patients will be entered to determine the maximum tolerated duration of FUDR infusion (Part B).
