About Clinical Trials

What is a clinical trial?
Cinical trials are biomedical or health-related research studies in human beings that follow a pre-defined protocol. Two common types of studies are interventional and observational.

Interventional studies
Research subjects are assigned by the investigator to a treatment or other intervention, and their outcomes are measured.

Observational studies
Individuals are observed and their outcomes are measured by the investigators.
