Clinical Trials and Their Phases

Clinical trials, by definition, are research studies performed on willing individuals, organized to evaluate the benefits and side effects of new treatments, including drugs, diets, or medical devices.

The institution that authorizes clinical trials is the U.S. Food and Drug Administration (FDA), but trials can be sponsored and initiated by pharmaceutical companies, medical centers, and foundations, universities, or other federal health agencies.

Clinical trials come after extensive laboratory tests and studies on animals. When the FDA grants permission to move to the next stage, there are four clinical trial phases to be performed on humans:


Brief Description

This phase is focused on safety, side effects, and finding the right drug dosage. It is usually conducted on smaller groups (20 to 80) of healthy individuals


Phase two focuses on the new drug’s effectiveness in people with a certain condition or disease. It requires more people (100 to 300) and can go on for several years

This phase extends safety and effectiveness research focusing on different populations and dosages, combining the new drug with other existing treatments. The test groups are even bigger, ranging from several hundred to several thousand individuals


Phase four starts after the FDA approves the new drug. Its side effects and effectiveness are monitored in big and diverse populations over a longer period

The specifics of each phase might vary depending on the medical aid that is being tested.
