- Other: laboratory biomarker analysis
- Registration Number
- NCT00025207
- Lead Sponsor
- National Cancer Institute (NCI)
- Brief Summary
Phase II trial to study the effectiveness of gefitinib in treating patients who have malignant mesothelioma. Biological therapies such as gefitinib may interfere with the growth of the tumor cells and slow the growth of malignant mesothelioma
- Detailed Description
OBJECTIVES:
I. Determine the activity of gefitinib, in terms of failure-free survival, in patients with malignant mesothelioma.
II. Determine the response rate in patients treated with this drug. III. Determine the toxicity of this drug in these patients. IV. Determine the overall survival of patients treated with this drug. V. Determine whether overexpression of epidermal growth factor receptor and expression of cyclo-oxygenase-2 can predict the effectiveness of this drug in these patients.
OUTLINE: This is a multicenter study.
Patients receive oral gefitinib once daily on days 1-21. Courses repeat every 3 weeks in the absence of disease progression or unacceptable toxicity.
Patients are followed every 2 months for 1 year and then every 6 months for up to 3 years.
PROJECTED ACCRUAL: A total of 40 patients will be accrued for this study within 7-10 months.

- Primary Outcome Measures
Name Time Method Percentage of patients who remain failure-free Time between the initiation of treatment and initial failure (disease progression, relapse, death), assessed up to 3 months Kaplan-Meier's product limit estimator and curves will be used.
- Secondary Outcome Measures
Name Time Method Toxicities, graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE) v3.0 Up to 4 years For each type of toxicity experienced, the frequency of reported toxicity will be summarized by the most severe grade.
Failure-free survival within patient subgroups defined in terms of epidermal growth factor receptor (EGFR) overexpression and cyclooxygenase-2 (COX-2) expression Up to 4 years An exact binomial confidence interval will be generated.
Overall survival Up to 4 years Kaplan-Meier's product limit estimator and curves will be used.
Tumor response rate Up to 4 years An exact binomial confidence interval will be generated.
