Clinical trial phases

Biomedical, clinical trials include the following four clinical research phases:

 

●       Phase I of clinical trials usually studies new drugs for the first time in a small group of people to evaluate a safe dosage range and identify side effects.

●       Phase II of clinical trials studies test treatments that were found safe in phase I of clinical trials. However, phase II is conducted on a larger group of human subjects for monitoring any adverse effects.

●       Phase III of clinical trials is conducted in different regions and countries and on larger populations. Phase III is the step conducted right before a new treatment or drug is approved.

●       Phase IV of clinical trials is conducted after a country approves, but there is still a need for further testing efficacy in a larger population over a longer timeframe.

 

There are various guidelines outlined by different international and national organizations for ensuring careful design, review, and completion of the process.
