Official Title: “Phase III, Randomized, Double-Blind, Placebo-Controlled Crossover Trial of Ondansetron in the Control of Chronic Nausea and Vomiting Not Due to Antineoplastic Therapy in Patients With Advanced Cancer”

RATIONALE: Antiemetic drugs, such as ondansetron, may help to reduce or prevent nausea and vomiting in patients with advanced cancer.

PURPOSE: This randomized phase III trial is studying how well ondansetron works compared to a placebo in treating patients with advanced cancer and chronic nausea and vomiting that is not caused by cancer therapy.

Study Type: Interventional

Study Design: Supportive Care, Randomized, Double-Blind, Placebo Control

Study Primary Completion Date: September 2001

OBJECTIVES: I. Compare the antiemetic effect of ondansetron vs placebo in patients with advanced cancer who suffer from chronic nausea and emesis that is not due to antineoplastic therapy (i.e., chemotherapy, radiotherapy, immunotherapy, biologic therapy). II. Determine the toxicity of ondansetron in these patients. III. Evaluate the use of other concurrent antiemetics in these patients when treated with this regimen.

OUTLINE: This is a randomized, double blind, placebo controlled, multicenter study. Patients are stratified according to abdominal carcinomatosis (yes vs no), renal insufficiency (creatinine less than 2.0 mg/dL vs creatinine at least 2.0 mg/dL), type of cancer (brain vs gastrointestinal vs other), and narcotic use (yes vs no). Patients are randomized to one of two treatment arms. Arm I: Patients receive oral ondansetron twice daily on days 1-7 and oral placebo twice daily on days 8-14 in the absence of unacceptable toxicity. Arm II: Patients receive oral placebo twice daily on days 1-7 and oral ondansetron twice daily on days 8-14 in the absence of unacceptable toxicity.

PROJECTED ACCRUAL: A total of 100 patients (50 per arm) will be accrued for this study within 1 year.
