Brief Summary

RATIONALE: Drugs used in chemotherapy, such as oxaliplatin and gemcitabine, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Erlotinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving oxaliplatin together with gemcitabine, erlotinib, and radiation therapy may kill more tumor cells.

PURPOSE: This phase I trial is studying the side effects and best dose of oxaliplatin, gemcitabine, and erlotinib when given together with radiation therapy in treating patients with unresectable and/or metastatic pancreatic cancer or biliary tract cancer.

Detailed Description

OBJECTIVES:

* Determine the maximum tolerated dose (MTD) of oxaliplatin and gemcitabine hydrochloride when combined with radiotherapy in patients with unresectable and/or metastatic pancreatic or biliary tract adenocarcinoma. (Part 1)

* Determine the MTD of erlotinib hydrochloride and gemcitabine hydrochloride when combined with oxaliplatin at the MTD and radiotherapy in these patients. (Part 2)

OUTLINE: This is a multicenter, nonrandomized, parallel group, uncontrolled, open-label, dose-escalation study of gemcitabine hydrochloride, oxaliplatin, and erlotinib hydrochloride.

* Part 1: Patients receive gemcitabine hydrochloride IV over 30-60 minutes and oxaliplatin IV on day 1. Patients also undergo external beam radiotherapy (EBRT) once daily on days 1-5. Treatment repeats every 7 days for up to 6 courses.

Cohorts of 3-6 patients receive escalating doses of gemcitabine hydrochloride and oxaliplatin 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 (DLT). Up to 10 patients are treated at the MTD.

* Part 2: Patients receive gemcitabine hydrochloride, oxaliplatin\*, and EBRT as in part 1. Patients also receive oral erlotinib hydrochloride once daily on days 1-5. Treatment repeats every 7 days for up to 6 courses.

Cohorts of 3-6 patients receive escalating doses of gemcitabine hydrochloride and erlotinib hydrochloride until the MTD is determined. The MTD is defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience DLT. Up to 10 patients are treated at the MTD.

NOTE: \*Patients receive oxaliplatin at the MTD determined in part 1.

After completion of study treatment, patients are followed every 3 months.

Primary Outcome Measures
NameTimeMethod
Maximum tolerated dose (MTD) of oxaliplatin and gemcitabine hydrochloride (Part 1)6 weeks

The MTC of Oxaliplatin and gemcitabine is defined as the combination for which the rate of toxicities that cause dose reductions plus twice the rate of dsoe limiting toxicity (DLT) is equal to 0.5

Maximum Tolerated Dose (MTD) of erlotinib hydrochloride and gemcitabine hydrochloride (Part 2)6 weeks

The highest dose for which the observed dose reduction rate plus twice the dose limiting toxicity (DLT) rate does not exceed 0.5 will be declared the MTD
