A National Regulatory Authority (NRA) is a government agency responsible for approving and overseeing clinical trials and medicinal products within its jurisdiction.
NRAs evaluate trial applications, monitor safety reporting, inspect research sites, and enforce regulatory compliance. Sponsors conducting multinational studies must coordinate with each applicable NRA to meet local regulatory requirements. Early engagement with NRAs helps align protocol design and reporting expectations. Effective NRA interaction reduces regulatory delays and strengthens compliant trial execution.
