About

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

PURPOSE: This phase I trial is studying the side effects and best dose of erlotinib hydrochloride when given together with gemcitabine hydrochloride and oxaliplatin in treating patients with advanced biliary tract cancer, pancreatic cancer, duodenal cancer, or ampullary cancer.

Full description

OBJECTIVES:

Primary

To determine the maximum tolerated dose and the recommended phase II dose of erlotinib hydrochloride in combination with gemcitabine hydrochloride and oxaliplatin in patients with advanced biliary tract cancer, pancreatic cancer, duodenal cancer, or ampullary cancer.

Secondary

To describe any antitumor activity associated with this treatment regimen when given during the dose-escalation and expanded-cohort portions of this study.
To evaluate e-cadherin, vimentin, fibronectin, amphiregulin, and Kras status in the tumors and assess their relationship to response.

OUTLINE: This is a multicenter, dose-escalation study of erlotinib hydrochloride.

Patients receive gemcitabine hydrochloride IV on day 1, oxaliplatin IV over 2 hours on day 2, and oral erlotinib hydrochloride once daily on days 3-8. Courses repeat every 2 weeks in the absence of disease progression or unacceptable toxicity.

Tumor tissue samples are collected for biomarker and other analysis.

After completion of study treatment, patients are followed up for 30 days.

Inclusion criteria

Only advanced carcinomas defined as unresectable or metastatic that are histologically or cytologically confirmed to be biliary tract, pancreas, duodenal, or ampullary carcinomas will be included.
Dose-escalation: Patients > 18 years of age with biopsy-confirmed advanced biliary tract adenocarcinoma, pancreas cancer, duodenal cancer, or ampullary cancer
MTD expansion cohort: Patients > 18 years of age with biopsy-confirmed advanced biliary tract adenocarcinoma only.
No prior chemotherapy or prior EGF receptor inhibitor therapy
Measurable tumor by imaging examination
Performance status (PS) 0-2 on the ECOG performance scale
Have pretreatment bilirubin<2.5x upper limit of normal (ULN), serum creatinine<1.5x ULN, AST and ALT <2.5xULN or in the presence of liver metastasis <5xULN, neutrophils>1500, platelets>100K, hemoglobin >9 g/dL
Patients - both males and females - with reproductive potential (ie, menopausal for less than 1 year and not surgically sterilized) must practice effective contraceptive measures throughout the study. Women of childbearing potential must provide a negative pregnancy test (serum or urine) within 14 days prior to registration.

Exclusion criteria

CNS metastases
Uncontrolled infection
Pregnant or nursing women may not participate.
No other prior malignancy is allowed except for the following: adequately treated basal cell or squamous cell skin cancer, in situ cervical cancer, adequately treated Stage I or II cancer from which the patient is currently in complete remission, or any other cancer from which the patient has been disease-free for 5 years.
Psychiatric illness that would prevent understanding the nature of the investigational therapy and complying with protocol requirements
Patients with > grade 2 neuropathy
Patients with > grade 2 uncontrolled nausea and vomiting despite antiemetics
Any concurrent medical condition that, in the judgment of the investigator, would make the patient an inappropriate candidate for study enrollment
Prior chemotherapy or EGFR inhibitor
