Statistical challenges in designing head-to-head clinical trials are not simply confined to sample size and power calculations, but include selection of critical efficacy and safety endpoints where benefit/risk can be properly evaluated and effectiveness determined.

What can be the regulatory role in formulating a framework for such a comparative effectivenss study?
