title: Economic evaluation of ondansetron: preliminary analysis using clinical trial data prior to price setting.
abstract: This study combines secondary analysis of efficacy and side-effect data from a randomised controlled trial with estimates of resource use to evaluate the likely economic effects of the new antiemetic agent ondansetron. Costs, effects and cost-effectiveness of ondansetron in the prophylaxis of acute nausea and vomiting induced by chemotherapy are assessed relative to antiemetic therapy with metoclopramide. Superior efficacy of ondansetron is quantified both in terms of significant emesis avoided and emesis management costs avoided. A simple cost analysis, with the metoclopramide dosage priced at 10 pounds, indicates that therapy with ondansetron would give equivalent net treatment costs, at a price ratio (ondansetron/metoclopramide) of 2.3 to 1. If therapeutic success is defined as the avoidance of emesis and antiemetic side-effects, then the two therapies would be equally cost-effective at a drug price ratio of 5 to 1. We conclude that, (i) economic evaluation prior to price setting is feasible and informative; (ii) such models can indicate prospective data collection priorities.
