Phase III Randomized Study of Ondansetron in Patients With Advanced Cancer and Chronic Nausea and Emesis Not Due to Antineoplastic Therapy
Alternate Title Ondansetron in Treating Patients With Advanced Cancer and Chronic Nausea and Vomiting Not Caused by Cancer Treatment
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. Entry Criteria Disease Characteristics: Diagnosis of incurable cancer with chronic nausea and vomiting lasting at least 1 week that is not due to antineoplastic therapy (i.e., chemotherapy, radiotherapy, immunotherapy, biologic therapy) Nausea not adequately controlled by standard antiemetics Prior/Concurrent Therapy: Biologic therapy: See Disease Characteristics Chemotherapy: See Disease Characteristics At least 2 weeks since prior cytotoxic systemic therapy No concurrent cytotoxic systemic therapy Endocrine therapy: Not specified Radiotherapy: See Disease Characteristics At least 2 weeks since prior radiotherapy to gastrointestinal tract No concurrent radiotherapy to gastrointestinal tract Surgery: Not specified Other: At least 2 weeks since prior 5-HT3 receptor antagonists (i.e., dolasetron, granisetron, or ondansetron) No other concurrent 5-HT3 receptor antagonists Other concurrent antiemetics allowed Patient Characteristics: Age: Not specified Performance status: Not specified Life expectancy: At least 6 weeks Hematopoietic: Not specified Hepatic: Not specified Renal: Not specified Cardiovascular: No uncontrolled hypertension Other: Not pregnant or nursing Able to take oral medication (feeding tube allowed) Able to swallow own saliva No prior phenylketonuria No known allergy or intolerance to 5-HT3 receptor antagonists No bowel obstruction Expected Enrollment A total of 100 patients (50 per arm) will be accrued for this study within 1 year. 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.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol. Back to Top |
