Last updated: October 28, 2025

Clinical trials are designed to answer specific medical questions, and to do that safely and accurately, each trial has clear rules about who can and cannot participate. These rules are called eligibility criteria, and they are based on scientific and ethical considerations to protect participants and ensure the reliability of the study.

Types of people who may be eligible to join a trial

  • Adults over 18 years of age, with or without medical conditions
  • Children or adolescents (under 18) with parental or guardian involvement
  • Healthy volunteers who want to contribute to medical research
  • Individuals with specific conditions who are seeking new treatments
  • People from specific demographic groups (e.g., age, gender, ethnicity)

Key Note: Eligibility does not mean you are required to join. Participation is always voluntary and based on informed consent.
