Each group involved in a clinical trial has specific responsibilities:

• Sponsors: Fund the trial and are responsible for its design and overall management
• Research Sites: Locations (e.g., hospitals or clinics) where the trial takes place
• Contract Research Organizations (CROs): Independent companies that help manage and monitor the trial on behalf of the sponsor
• Healthcare Professionals (HCPs): Doctors, nurses, and specialists who provide care, perform procedures, and ensure participant safety

Together, these groups ensure that the trial runs smoothly, data is accurate, and participants are protected.
