While IRB approval is essential, the practical next step at the site level is to formally delegate the task. The procedure is optional, so re-consenting all participants is not required unless the IRB specifically mandated it. The sponsor’s approval is typically obtained before IRB submission. The delegation log must accurately reflect who is authorized to perform any study procedure.

The participant’s distress and perception are real and must be addressed with empathy first. The CRC should follow the protocol’s predefined procedures for such situations, which are designed to maintain the blind whenever possible while ensuring participant safety and addressing concerns. Automatically breaking the blind or dismissing the concern is not appropriate. The event does not meet the definition of an adverse event based solely on a participant’s suspicion.

The root cause appears to be a training gap or lack of clarity in procedures, not willful neglect. The primary action is to remediate this gap. While the data must be entered and the delay documented per monitoring findings, it is not typically a reportable protocol deviation unless specified in the protocol. It is not an unanticipated problem posing risk to participants. A formal note-to-file should document the late entry and the corrective action taken (retraining).

Participant welfare is paramount. Ethical and regulatory guidelines require that participants are informed of significant changes, including study termination. The sponsor must work with investigators to manage a orderly close-out, which includes informing participants, addressing questions, and facilitating transition to standard care if the investigational product was providing a clinical benefit. Simply stopping or continuing treatment without oversight is not acceptable.

The ‘regulatory binder’ or ‘investigator site file’ (ISF) is a specific collection of essential documents as defined by ICH E6 GCP. It contains the key records that demonstrate the qualification of the site and staff, IRB approvals, protocol compliance, and proper conduct of the trial (e.g., 1572, CVs, IRB approvals, correspondence, delegation log). It does not primarily contain source data or sponsor-level documents.

A positive pregnancy test in a clinical trial is a significant finding that triggers specific protocol-mandated actions. The participant must be informed promptly and counseled. The PI and sponsor must be notified to assess the situation. While it may or may not be an SAE (depending on the drug’s risk and outcome), it is always a protocol-specified event that requires immediate and careful management. Waiting or ignoring the confirmatory serum result is not responsible.

According to FDA regulations and ICH GCP, when using a short-form consent document (stating that elements of consent were presented orally), an impartial witness must be present for the entire oral presentation. The witness must be fluent in both the language of the oral presentation and the participant’s language. The interpreter does not need formal certification (though it is best practice), and the short-form is in the participant’s language. The PI does not have to be present if a qualified designee is obtaining consent.

The Principal Investigator bears ultimate responsibility for the conduct of the study at the site. This includes the ongoing review of all relevant data, including lab reports, to ensure participant safety and protocol compliance. Delegating assessment to the CRC is standard, but the PI must still perform and document their own review in a timely manner. Simply filing a note or accepting a delay does not fulfill this core GCP obligation. The CRC should facilitate this process but must insist on the PI’s required oversight role.

The Clinical Trial Agreement is a legally binding contract that outlines the business and operational relationship. It specifies the protocol, budget, payment schedule, indemnification, liability, publication rights, and responsibilities of the sponsor and the site/investigator. While it references regulatory compliance, its primary focus is contractual. Delegation is covered by the DOA log, regulatory commitment by the 1572, and participant compensation is detailed in the IRB-approved consent form.

While IRB approval is essential, the practical next step at the site level is to formally delegate the task. The procedure is optional, so re-consenting all participants is not required unless the IRB specifically mandated it. The sponsor’s approval is typically obtained before IRB submission. The delegation log must accurately reflect who is authorized to perform any study procedure.0
