Phase IV Clinical Trial

Term from Clinical Trials industry explained for recruiters

Phase IV clinical trials are the ongoing studies that happen after a drug or treatment has been approved and is available to the public. Think of it as the "real-world testing" phase. While earlier phases (I, II, and III) test if a drug is safe and works well in controlled settings, Phase IV looks at how the medicine performs when used by the general population over a longer time. This helps catch rare side effects and understand how the treatment works in different groups of people. These studies are sometimes called "Post-Marketing Surveillance" or "Post-Authorization Safety Studies."
