The clinical testing of experimental treatments or drugs is generally done in three phases, each with different purposes. The early phases focus on testing safety in a small number of study subjects. Later phases are conducted to further test safety and also test efficacy. Each successive phase generally involves a larger number of people.
In many cases, the therapies and drugs investigated in clinical trials are not approved by regulatory agencies, such as the Food and Drug Administration (FDA) in the United States, and the benefits and risks of taking the treatment are not well known.
Participants in clinical trials may help others by contributing to medical research.
All clinical trials have guidelines about who can participate that are based on requirements such as age and type of disease. These requirements are used to identify appropriate participants for each trial and help to ensure that questions being studied can be adequately answered. Some clinical trials seek participants with illnesses or conditions to be studied in the clinical trial, while others need healthy participants.
