A Phase II Trial of ZD1839 (IRESSA®) for Patients With Recurrent or Metastatic Cancer of the Esophagus or Gastroesophageal Junction
RATIONALE: Gefitinib may stop the growth of tumor cells by blocking some of the enzymes
needed for cell growth.
PURPOSE: This phase II trial is studying how well gefitinib works in treating patients with
recurrent or metastatic esophageal or gastroesophageal junction cancer.
needed for cell growth.
PURPOSE: This phase II trial is studying how well gefitinib works in treating patients with
recurrent or metastatic esophageal or gastroesophageal junction cancer.
OBJECTIVES:
Primary
- Explore the activity of single agent gefitinib, in terms of response rate, in a patient
population with recurrent or metastatic esophageal or gastroesophageal junction cancer.
Secondary
- Assess the toxicity of this drug in these patients.
OUTLINE: Patients are stratified according to prior treatment (yes vs no).
Patients receive oral gefitinib once daily for at least 8 weeks in the absence of disease
progression or unacceptable toxicity.
After completion of study treatment, patients are followed periodically for survival.
PROJECTED ACCRUAL: A total of 76 patients will be accrued for this study.

DISEASE CHARACTERISTICS:
- Pathologically confirmed squamous cell carcinoma, adenocarcinoma, or large-cell
undifferentiated carcinoma of the esophagus or gastroesophageal junction
- Patients must have disease that is either metastatic (i.e., M1b by the
definitions of the American Joint Committee on Cancer 1997 staging system) or
recurrent after definitive therapy, and must be considered incurable by
conventional treatments
- Patients with small cell, or mixed small cell/non-small-cell histology are
ineligible
- Patients with lymphoma or sarcoma are also ineligible
- Disease must be measurable in at least one dimension by physical exam, x-ray, CT scan
or MRI, ultrasound, or endoscopy
- Measurable disease can be a previously irradiated lesion if disease growth has
been documented in the lesion since completion of radiation therapy
- An elevation in carcinoembryonic antigen (CEA) is not sufficient to use by
itself in response assessment
PATIENT CHARACTERISTICS:
- ECOG Performance Status 0-1
- WBC ≥ 3,000/mm^3
- Platelet count ≥ 100,000/mm^3
- Creatinine ≤ 2.0 mg/dL
- Alkaline phosphatase and AST < twice normal
- Bilirubin < twice normal
- Calcium normal
- No known severe hypersensitivity to study drug or any of its excipients
- No clinical evidence of any other uncontrolled malignancy except adequately treated
basal or squamous cell skin cancer or in situ cervical cancer
- Pregnant or nursing women are ineligible
- Fertile patients must use effective contraception
- No evidence of severe or uncontrolled systemic disease (e.g., unstable or
uncompensated respiratory, cardiac, hepatic, or renal disease)
- No evidence of clinically active interstitial lung disease
- Patients with chronic stable radiographic changes who are asymptomatic need not
be excluded
PRIOR CONCURRENT THERAPY:
- Patients may not have received more than one previous systemic treatment regimen
- Systemic treatment may have been given as part of definitive (adjuvant,
neoadjuvant, concurrent, or sequential) management or for metastatic or
recurrent disease
- Previously untreated patients are also eligible
- No previous treatment with study drug or any other epidermal growth factor receptor
(EGFR) antagonists
- More than 30 days since prior treatment with a non-approved or investigational drug
- At least 4 weeks must have elapsed since any surgery, radiation therapy, or
chemotherapy administration
- Recovered from previous oncologic or other major surgery
- No concurrent barbiturates (e.g., phenytoin), carbamazepine, rifampicin,
phenobarbital or Hypericum perforatum (St. John's wort)
- No concurrent surgery, radiation therapy, hormonal therapy, or other chemotherapy
