Participation in clinical trials is typically voluntary, and individuals who choose to participate are usually provided with detailed information about the trial, including its purpose, procedures, potential risks and benefits, and their rights as participants. Informed consent is obtained from each participant or their legally authorized representative before they can enrol in a clinical trial.

People of all ages, including children, can participate in clinical trials, but certain trials may have age restrictions based on the intervention being tested and its potential risks or benefits for different age groups.

By participating in clinical trials, individuals contribute to advancing medical knowledge and potentially gaining access to innovative treatments before they become widely available. Clinical trial results help determine the safety and effectiveness of interventions and guide healthcare decisions, leading to improved medical practices and patient care.
