Docetaxel With or Without Infliximab in Treating Weight Loss, Loss of Appetite, and Fatigue in Patients With Unresectable Non-Small Cell Lung Cancer (Infliximab Treatment Discontinued Effective 10/05/05)

Overview

RATIONALE: Drugs used in chemotherapy, such as docetaxel, work in different ways to stop tumor cells from dividing so they stop growing or die. Infliximab may improve cancer-related weight loss, lack of appetite, and fatigue. It is not yet known whether docetaxel is more effective with or without infliximab in preventing weight loss and fatigue in patients with advanced cancer. (Infliximab treatment discontinued effective 10/05/05) PURPOSE: Randomized phase III trial to determine the effectiveness of docetaxel with or without infliximab in preventing weight loss, loss of appetite, and fatigue in patients who have unresectable non-small cell lung cancer. (Infliximab treatment discontinued effective 10/05/05)

OBJECTIVES: * Compare the improvement or stabilization of weight in elderly or poor performance status patients with unresectable non-small cell lung cancer treated with docetaxel with or without infliximab (infliximab treatment discontinued effective 10/05/05). * Compare appetite and functional status in patients treated with these regimens. * Compare the toxicity of these regimens in these patients. * Compare the augmentation or maintenance of lean tissue in patients treated with these regimens. * Compare the response rates and time to disease progression in patients treated with these regimens. * Compare the survival of patients treated with these regimens. * Determine whether the tumor necrosis factor-alpha polymorphisms in the -308 and -238 regions predict which cancer patients will experience loss of appetite and weight and which patients might potentially benefit from infliximab (infliximab treatment discontinued effective 10/05/05). OUTLINE: This is a randomized, double-blind, placebo-controlled, multicenter study. Patients are stratified according to weight loss within the past 6 months (0% vs more than 0% to less than 5% vs at least 5%), number of prior chemotherapy regimens (0 vs 1 vs more than 1), gender, and GBU prognostic index (good vs bad vs unsure). * Part A (non-randomized, single-center portion of study): Five patients receive infliximab IV (infliximab treatment discontinued effective 10/05/05) over 2 hours once weekly on weeks 1, 3, and 5 of the first course and once weekly on weeks 1 and 5 of all subsequent courses and docetaxel IV over 1 hour (immediately after completion of infliximab infusion \[infliximab treatment discontinued effective 10/05/05\]) once weekly on weeks 1-6 of each course. Treatment repeats every 8 weeks for 2-3 courses in the absence of disease progression or unacceptable toxicity. If none of the 5 patients experiences any grade 4 or 5 toxicity directly attributable to infliximab (infliximab treatment discontinued effective 10/05/05), additional patients are accrued for part B of the study. * Part B (randomized, multicenter portion of study): Patients are randomized to 1 of 2 treatment arms. * Arm I (infliximab treatment discontinued effective 10/05/05): Patients receive infliximab and docetaxel as in part A. * Arm II: Patients receive docetaxel as in part A and placebo IV over 2 hours according to the infliximab schedule in part A (infliximab treatment discontinued effective 10/05/05). Treatment in both arms repeats as in part A. Quality of life, fatigue, appetite/anorexia, cachexia, and weight are assessed at baseline, weekly on weeks 1-8, and then monthly for the remainder of study treatment. Patients are followed every 6 months for 5 years.
