The short version
- The sponsor starts and funds the study; it can be a company, university or agency.
- Sites are the places where participants take part; investigators lead the work there.
- An institutional review board reviews a study for ethics and participant protection.
Sponsor
The sponsor is the organization responsible for starting and managing the study. It might be a pharmaceutical company, a university, or a government agency.
Site and investigator
A site is a hospital, clinic or research center. The principal investigator is the person who leads the study at that site and answers to the sponsor and review board.
Review board
An IRB, or ethics committee, reviews a study before it begins and while it runs, with a particular focus on participants’ rights and safety.
Where we fit
We are none of these. We only publish general information about how they work.
Regisara is an information website, not a medical provider, research sponsor, study site, or recruiter. It does not give medical advice, diagnosis or treatment, run or recruit for studies, match you with trials, or share your details with study sponsors, research sites, or other partners. Nothing here is medical, legal, or financial advice.
