The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) E6 guideline, "Good Clinical Practice (GCP)", is a cornerstone of ethical and scientific quality in clinical trials. Within this crucial document, the definition of an audit holds significant weight, influencing how clinical trials are monitored and ensuring data integrity. This article will explore the ICH E6 definition of an audit, its purpose, and its role in maintaining the high standards expected in clinical research.

What ICH E6 Says About Audits

ICH E6 doesn't explicitly provide a single, concise definition of an audit in a standalone sentence. Instead, the guideline defines the purpose of an audit and the activities involved, allowing us to infer a comprehensive definition. In essence, according to ICH E6, an audit is a systematic and independent examination of trial-related activities and documentation to determine whether the trial is being conducted and the data are being generated, documented, and reported in compliance with the protocol, the applicable regulatory requirements, and GCP.

This definition encompasses several key aspects:

• Systematic: Audits follow a pre-defined plan and methodology, ensuring consistency and thoroughness.
• Independent: The auditor(s) must be free from any influence or pressure that could compromise their objectivity.
• Examination: Audits involve a detailed review of documents and processes, not just a superficial glance.
• Compliance: The primary goal of an audit is to verify compliance with GCP, protocol requirements, and applicable regulations.

The Purpose of an Audit in Clinical Trials (as per ICH E6)

The overarching purpose of an audit, as implied by ICH E6, is to provide assurance that the clinical trial is being conducted in accordance with the highest ethical and scientific standards. This assurance benefits several stakeholders:

• Sponsors: Audits help sponsors confirm that their investment in the trial is yielding reliable and trustworthy data.
• Regulatory Authorities: Audits help regulatory agencies verify that trials meet their requirements and protect patient safety.
• Patients: Audits contribute to ensuring that patient rights and welfare are protected throughout the trial.
• Investigators: Audits provide investigators with feedback to improve their trial conduct and adherence to GCP.

Distinguishing Audits from Monitoring and Inspections

It's crucial to distinguish audits from other oversight activities:

• Monitoring: This involves the ongoing review of trial progress by the sponsor or its designee to ensure adherence to the protocol and GCP. Monitoring is more frequent and less formal than an audit.
• Inspections: These are conducted by regulatory authorities to verify compliance with GCP and applicable regulations. Inspections can be triggered by various factors, including audit findings.

Key Aspects of an ICH E6 Compliant Audit

Several key elements contribute to an audit that aligns with the principles of ICH E6:

• Audit Scope and Plan: A well-defined scope outlines the specific areas to be audited. A detailed plan outlines the methodology, timelines, and resources needed.
• Selection of Audit Sites: The selection process should be objective and representative of the overall trial.
• Documentation Review: This involves examining all relevant documents, including case report forms, laboratory data, and investigator site files.
• Interviewing Personnel: Interviews help clarify processes and identify potential issues.
• Reporting and Follow-up: Audit findings should be documented in a comprehensive report, including recommendations for corrective and preventive actions (CAPAs).

Conclusion: The Importance of Audits in Maintaining GCP

The ICH E6 guideline underscores the critical role of audits in ensuring the quality and integrity of clinical trials. By systematically and independently examining trial-related activities and documentation, audits contribute to safeguarding patient safety, promoting ethical conduct, and generating reliable data. Understanding the implied definition of an audit within ICH E6 is essential for all stakeholders involved in the clinical research process. Adherence to GCP standards, as guided by ICH E6, is paramount for the successful conduct of clinical trials and the advancement of medical knowledge.
