The Principal Investigator (PI) has the responsibility to oversee all trial related activities including any activities delegated to other personnel. To protect participants’ rights, safety, and welfare, the PI must have the human and technological resources to implement the trial as designed, assess adverse events, and ensure the conduct appropriately minimizes risks to participants. In decentralized trials, a 3rd party vendor may be engaged to perform in home services. PI and institution may have other concerns about meeting requirements for ensuring adequately qualified staff, providing training on the protocol, and assuring the integrity of study data.
