Investigational Drug — What It Means in Clinical Trials
Plain English Definition
An investigational drug is a medicine that is being tested in clinical trials but has not yet been approved by regulators like the FDA or EMA for general use. It may also be called an "experimental drug" or "study drug." Investigational drugs can only be given to participants as part of a clinical trial or through expanded access programs.
Why It Matters
If you join a trial, you will likely be taking an investigational drug. This means its full safety profile is not yet known. The consent form will explain what is known so far and what risks are anticipated.
Example
A listing will typically state: "The investigational drug (Drug X) is not approved for the treatment of this condition." This is standard regulatory language.
