Arms of the Study

Experimental
Arm I
Patients receive oral ZD 1839 daily. Beginning on day 15, patients receive irinotecan IV over 90 minutes, leucovorin calcium IV over 15 minutes, and fluorouracil IV weekly on weeks 1-2. Treatment repeats every 3 weeks in the absence of disease progression or unacceptable toxicity. Cohorts of 3-6 patients receive escalating doses of ZD 1839 until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Once the MTD is determined, 10 additional patients are accrued to receive treatment at the MTD.
