Difference Between Phase I, Phase II and Phase III Clinical Trials

The journey of developing a new medical treatment from a laboratory concept to a publicly available therapy is a meticulous, lengthy, and highly regulated process. At the core of this journey are clinical trials, which are systematic investigations in human subjects designed to evaluate the safety and efficacy of a new drug or intervention. This process is broken down into distinct stages, ensuring that the research progresses logically and safely. Understanding the structure of phase i ii and iii clinical trials is fundamental for anyone involved in medical research and development.
