According to ICH E6, an Audit is Defined As... A Deep Dive into Good Clinical Practice

The International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use (ICH) E6 guideline, "Good Clinical Practice (GCP)", provides a framework for designing, conducting, recording, and reporting clinical trials. Within this framework, the definition and execution of audits play a crucial role in ensuring data integrity and the overall quality of clinical research. This article delves deep into the ICH E6 definition of an audit, exploring its purpose, scope, and implications for all stakeholders involved in clinical trials.

Understanding the ICH E6 Definition of an Audit

ICH E6 doesn't offer a concise, standalone definition of "audit" in a single sentence. Instead, the guideline implicitly defines an audit through its description of the audit process and its objectives. Essentially, an audit within the context of ICH E6 is a systematic and independent examination of trial-related activities and documentation to determine whether the trial was conducted and the data were recorded, handled, and reported in accordance with the protocol, GCP, and the applicable regulatory requirements.

This definition highlights several key aspects:

• Systematic: Audits are not random checks. They follow a predefined plan and methodology, ensuring comprehensive coverage of relevant areas.
• Independent: The auditors must be free from any influence or bias related to the trial's conduct. Independence ensures objectivity and credibility of the audit findings.
• Examination: The audit involves a thorough review of documentation and potentially interviews with personnel involved in the trial.
• Compliance: The core purpose of the audit is to verify compliance with the protocol, GCP, and regulatory requirements. This includes assessing adherence to procedures, data management practices, and ethical considerations.

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

The overarching purpose of an audit, as implied by ICH E6, is to protect the rights, safety, and well-being of trial participants and to ensure the credibility and integrity of clinical trial data. This is achieved through several specific objectives:

1. Ensuring Compliance with GCP and Regulatory Requirements:

This is arguably the most important purpose. Audits verify that all aspects of the trial, from protocol development to final report submission, adhere to the established GCP guidelines and relevant regulatory expectations. Non-compliance can lead to serious consequences, including trial termination, data invalidation, and regulatory sanctions.

2. Identifying Deviations and Non-Conformances:

Audits systematically identify deviations from the protocol and any non-conformances with GCP or regulatory requirements. This allows for timely corrective actions and prevents the repetition of errors. Early detection of problems is crucial for maintaining data integrity.

3. Evaluating the Effectiveness of Quality Systems:

Audits assess the effectiveness of the systems and processes in place to ensure the quality and integrity of the clinical trial. This includes reviewing SOPs (Standard Operating Procedures), training programs, and data management systems. Weaknesses identified during audits can lead to improvements in quality systems.

4. Enhancing Data Integrity:

Data integrity is paramount in clinical trials. Audits contribute significantly to maintaining data integrity by ensuring that data are accurately recorded, handled, and reported. Any inconsistencies or potential data manipulation can be identified and addressed.

5. Supporting Regulatory Inspections:

Audits can significantly assist in preparing for regulatory inspections. By proactively identifying and rectifying issues, sponsors and investigators can demonstrate their commitment to GCP compliance and increase the likelihood of a successful inspection.

Scope of an ICH E6 Compliant Audit

The scope of an audit is determined by several factors, including the specific objectives, the type of trial, the involved parties (sponsor, investigator, CRO), and the applicable regulations. However, some common areas covered by ICH E6 compliant audits include:

1. Protocol Adherence:

The audit will verify that all trial activities were conducted in accordance with the approved protocol. This includes reviewing the study design, inclusion/exclusion criteria, treatment assignments, and data collection methods.

2. Investigator Site Files:

A thorough review of investigator site files is a critical part of the audit. This involves examining case report forms (CRFs), source documents, consent forms, and other relevant documents to ensure data accuracy and completeness.

3. Data Management:

The audit will scrutinize the data management processes, including data entry, validation, cleaning, and storage. This ensures that data are handled in a secure and accurate manner and that data integrity is maintained.

4. Subject Safety Monitoring:

Audits will examine the systems in place for monitoring subject safety. This includes reviewing adverse event reporting, safety data analysis, and the implementation of safety measures.

5. Quality Control and Assurance:

The audit will evaluate the quality control and quality assurance procedures implemented throughout the trial. This includes reviewing SOPs, training records, and other documentation related to quality management.

6. Regulatory Compliance:

Audits ensure compliance with all applicable regulatory requirements, including those related to ethics, data privacy, and informed consent.

Types of Audits within the ICH E6 Framework

While ICH E6 doesn't explicitly categorize audit types, different types of audits are commonly conducted within the framework of GCP:

1. Sponsor Audits:

These audits are conducted by the sponsor or their designated representatives to assess the conduct of the clinical trial at investigator sites. They are crucial for verifying compliance with the protocol and GCP guidelines.

2. Investigator Audits (Internal Audits):

Investigators may conduct internal audits to assess their own compliance with GCP and the trial protocol. This proactive approach helps identify and correct issues before they are detected during a sponsor audit.

3. Regulatory Inspections:

Regulatory authorities conduct inspections to verify compliance with GCP and applicable regulations. These inspections are more extensive than typical sponsor audits and can result in significant consequences if non-compliance is identified.

4. CRO Audits:

If a Contract Research Organization (CRO) is involved in the trial, the sponsor will likely audit the CRO's activities to ensure compliance with GCP and the contract agreement.

The Audit Process: A Step-by-Step Guide

The specific audit process may vary depending on the organization and the specific objectives, but a typical audit generally follows these steps:

1. Planning: Define the scope, objectives, methodology, and timeline of the audit. Develop an audit plan that outlines the specific areas to be reviewed.

2. Selection of Audit Sites/Documents: Select the sites or documents to be audited based on risk assessment and the audit plan.

3. On-Site Audit (if applicable): Conduct on-site visits to review documents and interview personnel at the selected sites.

4. Document Review: Thoroughly review all relevant documentation, including protocols, case report forms (CRFs), investigator site files, and other relevant materials.

5. Interviewing Personnel: Conduct interviews with key personnel involved in the trial to gather information and clarify any issues.

6. Audit Findings Documentation: Document all audit findings, including deviations from the protocol or GCP, non-conformances, and corrective actions needed.

7. Report Writing: Prepare a comprehensive audit report summarizing the findings, conclusions, and recommendations.

8. Follow-up: Follow up on the identified issues to ensure that corrective actions are implemented effectively.

Importance of Documentation in ICH E6 Audits

Meticulous documentation is paramount throughout the entire audit process. All audit activities, including planning, execution, and reporting, must be thoroughly documented. This documentation serves several critical purposes:

• Provides evidence of compliance: Audit documentation serves as evidence of the trial's adherence to GCP and regulatory requirements.

• Supports regulatory inspections: Comprehensive documentation facilitates a successful regulatory inspection.

• Facilitates timely corrective actions: Detailed audit findings enable the prompt identification and correction of any identified issues.

• Enables continuous improvement: Audit documentation helps identify areas for improvement in processes and systems to ensure continuous quality enhancement.

Conclusion: The Cornerstone of Clinical Trial Integrity

According to the principles underlying ICH E6, audits are not merely a regulatory requirement; they are a fundamental component of ensuring the integrity of clinical trials. They serve to protect trial participants, maintain data reliability, and uphold the overall quality of clinical research. By proactively embracing a robust audit process, stakeholders can significantly contribute to the advancement of safe and effective medical treatments. Understanding the intricacies of ICH E6 guidelines and their implications for auditing is essential for every professional involved in the lifecycle of a clinical trial. The commitment to a rigorous and transparent audit process reflects a commitment to ethical research practices and the generation of reliable scientific data.
