RATIONALE: Gefitinib may stop the growth of tumor cells by blocking the enzymes necessary for tumor cell growth. Celecoxib may slow the growth of cancer by stopping blood flow to the tumor. Combining gefitinib with celecoxib may kill more tumor cells.

PURPOSE: Phase II trial to study the effectiveness of combining gefitinib with celecoxib in treating patients who have non-small cell lung cancer that is refractory to platinum-based chemotherapy (such as cisplatin or carboplatin).

Condition	Treatment or Intervention	Phase
recurrent non-small cell lung cancer	Drug: celecoxib  Drug: gefitinib  Procedure: anti-cytokine therapy  Procedure: biological response modifier therapy  Procedure: enzyme inhibitor therapy  Procedure: growth factor antagonist therapy  Procedure: protein tyrosine kinase inhibitor therapy	Phase II

Further Study Details: 

OBJECTIVES: Primary

• Determine the response rate in patients with platinum-refractory non-small cell lung cancer treated with gefitinib and celecoxib.

Secondary

• Determine the progression-free and overall survival of patients treated with this regimen.
• Determine the toxicity of this regimen in these patients.

OUTLINE: Patients receive oral gefitinib once daily and oral celecoxib twice daily on days 1-28. Treatment repeats every 28 days for up to 3 courses in the absence of disease progression or unacceptable toxicity.

Patients are followed for up to 6 weeks.

PROJECTED ACCRUAL: A total of 18-27 patients will be accrued for this study within 22 months.

Ages Eligible for Study:  18 Years and above,  Genders Eligible for Study:  Both
