Smaller sample sizes for phase II trials based on exact tests with actual error rates by trading-off their nominal levels of significance and power

Sample sizes for single-stage phase II clinical trials in the literature are often based on exact (binomial) tests with levels of significance (alpha (α) <5% and power >80%). This is because there is ...
