What is Clinical Trials?
Clinical trials are research studies performed in people that are aimed at evaluating a medical, surgical, or behavioral intervention. They are the primary way that researchers find out if a new treatment, like a new drug or diet or medical device, is safe and effective in people.
Historical Background
The history of clinical trials dates back to the 18th century, with early examples including James Lind's study on scurvy. Modern clinical trials have evolved with stringent ethical guidelines and regulatory oversight.
