Phase 1 clinical trials often involve people without the condition being studied, called healthy participants. Including healthy participants helps us understand how a study drug or study vaccine affects the body, determine proper dosing, and collect information about possible side effects. This is one way to learn more about a potential treatment before giving it to patients with complex medical histories.
In some obesity clinical trials, healthy participants may also need to meet certain BMI criteria. Because things like weight and metabolism can impact how medication works, it’s important to include participants that resemble the patient population. This improves the accuracy and reliability of the data and ensures that future patients receive medications founded on high-quality research.
