What is a "clinical trial"?
A clinical trial is a research study performed to test new medical treatments, drugs, or procedures on people. The goal is to determine if these new methods are safe and effective. Participants in clinical trials receive the treatment that is being tested and are closely monitored for any effects. Trials are performed in phases, with each phase designed to answer specific questions about the treatment’s safety, dosage, and effectiveness before it becomes widely available.
Examples
The new drug is currently undergoing a clinical trial to assess its safety and efficacy.
Participants in the clinical trial were monitored closely for any adverse reactions.
