Research Abstract

The major objective of the research was on the challenging issues and recent methodological developments that may be applicable in the rapid growing area of research on innovative clinical trials design and analysis including adaptive designs, enrichment designs, analysis for multiple objectives. We provides efficient strategies for designing the clinical trials with multiple co-primary endpoints within group-sequential designs. In addition, we discuss adaptive enrichment method in confirmatory clinical trials, using method combing the partition testing and graphical approach. we also identify common practical issues in multi-regional clinical trials via case studies.
