Gefitinib in Treating Patients With Recurrent or Metastatic Esophageal or Gastroesophageal Junction Cancer
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.
|Study Design:||Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||A Phase II Trial of ZD1839 (IRESSA®) for Patients With Recurrent or Metastatic Cancer of the Esophagus or Gastroesophageal Junction|
- The Number of Patients With Complete or Partial Response Rate of Single Agent ZD1839 in a Patient Population With Recurrent or Metastatic Cancer of the Esophagus or Gastroesophageal Junction, Using the RECIST 1.0 Criteria. [ Time Frame: at 8 weeks after initiation of treatment ] [ Designated as safety issue: No ]The overall response is the number of patients with the best response recorded in measurable disease (target lesions) from start to disease progression.Complete response is the number of patients with the disappearance of all target lesions. Partial response is the number of patients with larger than or equal to 30% decrease in sum of the longest diameters from baseline. Progressive disease is larger than or equal to 20% increase in sum of the longest diameters over the smallest sum observed or appearance of new lesions. Stable disease is neither PR nor PD criteria met.
|Study Start Date:||October 2005|
|Study Completion Date:||August 2011|
|Primary Completion Date:||January 2011 (Final data collection date for primary outcome measure)|
ZD1839 treatment will be taken once a day PO, every day about the same time
- 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.
- 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.
