Question

A pharmaceutical company has developed a novel drug for the treatment of asthma. The company hypothesizes that its new drug has similar efficacy compared to another treatment that is currently on the market, but only needs to be taken once a day instead of three times a day. The pharmaceutical company wants to maximize its profits by minimizing the trial duration and sample size. In addition, to better understand which sub-populations benefit most from the drug, the company has pre-specified parameters for adjusting the sample size in favor of the sub-population that is showing the greatest benefit. Which study design best describes this scenario?
