- Abstract
- Continuous endpoints are common in clinical trials. The design and analysis of such trials is often based on models assuming normally distributed data, possibly after an appropriate transformation. When planning a new trial, information on the variance of the endpoint is usually available from historical trials. Although the idea to use historical data for a new trial is not new, literature on how to formally summarize and use these data on variances is scarce. The meta-analytic-predictive (MAP) approach consists of a random-effects meta analysis of the historical variance data and a prediction of the variance in the new clinical trial. Two applications that rely on the MAP approach are considered: first, the selection of the sample size in the new trial, guided by the prediction of the variance; and, second, the inclusion of the predicted variance in a Bayesian analysis of the new trial. A clinical trial in patients with wet age-related macular degeneration illustrates the methodology. (C) 2016 Elsevier B.V. All rights reserved.
