What is a clinical trial?

A clinical trial (also clinical research) is a research study in human volunteers to answer specific health questions.

Carefully conducted clinical trials are the fastest and safest way to find treatments that work in people and ways to improve health.

Every clinical study must be approved and monitored by an Institutional Review Board or Ethics Committee to make sure the risks are as low as possible and that the rights of participants are protected. 

Why participate in a clinical trial?

Participants in clinical trials can play a more active role in their own health care, gain access to new research treatments before they are widely available, and help others by contributing to medical research.

Who can participate in a clinical trial?

All clinical trials have guidelines about who can participate. Using inclusion/exclusion criteria is an important principle of medical research that helps to produce reliable results.

How many clinical trial phases are there?

Covid-19 clinical trialFor a treatment or drug to be used commercially, it has to go through 4 phases that can last years in analysis and studies.

If the drug successfully passes through Phases I, II, and III, it will usually be approved by the national regulatory authority for use in the general population.

Summary of clinical trial phases

Phase I

First study of a new drug in people
Determines whether drug is safe to check for efficacy

Phase II

Study to learn if a new drug is safe and understand how it affects certain health conditions
Determines whether drug can have any efficacy; at this point, the drug is not presumed to have any therapeutic effect

Phase III

Study confirming if a drug is effective at improving a health condition
Determines a drug's therapeutic effect; at this point, the drug is presumed to have some effect

Phase IV

Continued research after a drug is approved for public use.
Monitor long-term effects
