Seamless phase 2/3 combination designs (or phase 2/3 designs) hold great promise to bring optimal treatment to patients early and more efficiently. The concept is to combine traditional phase 2 and phase 3 trials seamlessly in operation and inferentially in statistical analysis. As phase 2/3 designs cover a large area of clinical applications, it is not possible to provide comprehensive details for all different clinical applications in this article.
