a study on Lung Cancer
RATIONALE: Drugs used in chemotherapy, such as gemcitabine hydrochloride and carboplatin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Pemetrexed disodium and celecoxib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. It is not yet known whether giving gemcitabine hydrochloride or pemetrexed disodium together with carboplatin is more effective with or without celecoxib in treating non-small cell lung cancer.
PURPOSE: This randomized phase III trial is studying gemcitabine hydrochloride, pemetrexed disodium, and carboplatin to compare how well they work when given together with celecoxib or a placebo in treating patients with advanced non-small cell lung cancer.
A Randomized Phase III Double Blind Trial Evaluating Selective COX-2 Inhibition in COX-2 Expressing Advanced Non-Small Cell Lung Cancer
OUTLINE: This is a multicenter study. Patients are stratified according to gender, disease stage (IIIB vs IV), histology (squamous cell carcinoma vs non-squamous cell carcinoma), smoking status (never/former light smoker [defined as ≤ 10 pack years AND quit ≥ 1 year ago] vs smoker), and COX-2 expression status (COX-2 index ≥ 4 vs COX-2 index ≥ 2 but < 4). Patients are randomized to 1 of 2 treatment arms.
In both arms, treatment repeats every 21 days for up to 6 courses in the absence of disease progression or unacceptable toxicity. After completion of 6 courses, patients with responding or stable disease may continue to receive celecoxib or placebo alone in the absence of disease progression or unacceptable toxicity.
Patients may undergo blood and urine sample collection periodically for correlative laboratory studies.
After completion of study therapy, patients are followed up every 2 months for 2 years and then every 6 months for 3 years.
