Resumen
Fecha de inicio: 1 de agosto de 2007
Fecha en la que se inscribió al primer participante.OBJECTIVES: Primary * To evaluate the efficacy of aprepitant as monotherapy for opioid-induced nausea and vomiting (OINV) in comparison to ondansetron hydrochloride in patients who have failed at least one prior anti-emetic agent/regimen. Secondary * To determine whether control of OINV improves quality of life. * To determine if control in OINV decreases pain. * To determine if control in OINV improves mood. OUTLINE: Patients are randomized to 1 of 2 treatment arms. * Arm A: Patients receive aprepitant orally once daily for 7 days in the absence of unacceptable toxicity or persistent grade 4 nausea and vomiting. * Arm B: Patients receive ondansetron hydrochloride orally 3 times daily for 7 days in the absence of unacceptable toxicity or persistent grade 4 nausea and vomiting. Patients complete the following questionnaires: Functional Assessment of Cancer Therapy-General (FACT-G); Center for Epidemiologic Studies Depression Scale (CES-D); and Brief Pain Index (BPI) at baseline and on day 7. Patients also complete symptom diaries documenting the following: number of episodes (an emetic episode is defined as a simple vomit or retch, or any number of continuous vomits or retches; distinct episodes that are separated by at least 1 minute) of vomiting or retching including the date and time; worst and average degree of nausea (recorded every 2 hours while awake during the first 24 hours after treatment and every 8 hours on days 1-7); and adverse events other than episodes of vomiting and nausea.
