How Are Clinical Trial Phases and their Endpoints Related?

Now that you are familiar with the common endpoints used in clinical trials, let’s see what role they play in clinical trials that bring about drug approvals, for instance. 

Clinical trials progress through four main phases, each with specific goals and endpoints that build on the previous phase’s findings. As trials advance, endpoints evolve from basic safety measures to detailed effectiveness and quality-of-life outcomes, ultimately guiding the treatment's approval and real-world use.
