This agreement outlines the responsibilities and expectations of both the sponsor and the site, including budget considerations and compliance with regulatory requirements. Having this agreement in place ensures that the site is authorized to conduct the trial and is aware of the sponsor's obligations regarding compensation for the site's services, coverage for the subjects, and other logistical aspects critical to the conduct of the trial.
