Challenges in Designing Clinical Trials for Rare Diseases
*Chris Coffey, University of Iowa Keywords: rare diseases, small clinical trials, adaptive designs Designing clinical trials in the rare disease setting presents unique challenges to the clinical trials community. Summary statistics from small trials are often imprecise, so that the trials have adequate power to detect only large effects of interventions. Furthermore, many standard statistical techniques are based on large sample assumptions and may not have desirable properties in the small sample setting. As a consequence, the importance of adequate study planning is magnified in small clinical trials. Hence, it is critically important to have a true collaboration between study investigators and statisticians. Based on recent experience with the Network for Excellence in Neuroscience Clinical Trials (NeuroNEXT), this presentation will review some specific designs that seem useful in the rare disease setting. In particular, this presentation will address how adaptive designs (which have received substantial interest recently) can be useful in the rare disease setting – and what specific barriers currently impede the use of adaptive designs in current funding environments.
