What is pharmaceutical data integrity?

Pharmaceutical data integrity refers to the assurance that all data generated, recorded, processed and maintained throughout the drug lifecycle is complete, consistent, accurate and reliable. Regulators, such as the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA), emphasize the necessity of trustworthy data because decisions about product quality, regulatory compliance and patient safety depend on it.

Key principles of data integrity

The concept of data integrity is often explained through the acronym, ALCOA, and the more current ALCOA++ principles. Initially conceived by the U.S. FDA, ALCOA is an acronym representing the essential attributes of reliable data.

A - Attributable: All data must be clearly linked to the person or system that created it and when. This ensures accountability for all data entries and modifications.

L - Legible: Data should be readable and understandable throughout its lifespan. Clarity is paramount for accurate interpretation.

C - Contemporaneous: Data must be recorded at the time of the event or activity it describes, not later. Real-time recording prevents inaccuracies and enhances trustworthiness.

O - Original: The initial record must be preserved, either as the original document or a certified true copy. This ensures the authenticity of the information.

A - Accurate: Data should be error-free and reliable, with amendments properly documented. Precision is fundamental to reliable decision-making.

The "++" refers to guideline expansions made since ALCOA was originally conceived in the early 1990s. As the pharmaceutical regulatory environment has evolved, various regulatory bodies have expanded upon the core principles to include:

Complete: All required data should be present in its entirety. No omissions should compromise the integrity of the data.

Consistent: Data should be presented in a sequential and coherent manner. Standardized practices minimize ambiguity.

Enduring: Data must be recorded and stored in a format that ensures it remains accessible and readable over time. Long-term preservation is key.

Available: Data must be readily accessible for review, auditing, and retrieval when needed by authorized personnel.  This includes both current and archived information.

Traceable: Data should be traceable back to its origin, with audit trails that document its entire history and modifications made.

The FDA still abides by these principles, and current revisions being considered for EU GMP Chapter 4 formalize all 10 ALCOA principles, underpinning its continued relevance to pharmaceutical companies’ use in ensuring adherence to data integrity rules and maintaining regulatory compliance.

What is EU GMP Chapter 4?

EU GMP Chapter 4 is the section of the EudraLex Volume 4: EU Guidelines for Good Manufacturing Practice for Medicinal Products for Human and Veterinary Use that focuses on documentation. The current version has been in effect since January 2011. 

What's changing in EU GMP Chapter 4?

In addition to formalizing ALCOA++ data integrity principles, the revisions to EU GMP Chapter 4 reflect a heightened emphasis on risk management and data governance. The changes are designed to address technical and market factors that have emerged since the latest Chapter 4 version was published in 2011.

While the chapter has always addressed documentation, the updates provide more explicit guidance for ensuring the integrity of all data generated and processed within a pharmaceutical quality system. Key areas of focus include:

• Data governance: Organizations must ensure proper systems are in place that support data integrity no matter the format (paper, electronic or hybrid).

• Data lifecycle management: Data must be properly controlled from its creation through archiving and eventual deletion, ensuring integrity at every stage.

• Risk-based approach: Pharma must take steps to proactively identify and mitigate data integrity risks throughout the documentation lifecycle.

• ALCOA++ data integrity: Formalizing use of ALCOA++ principles as essential for the proper management and control of documents and records.

Notably, the regulatory updates apply to paper, electronic and hybrid documentation methods, and include controls for computerized systems and artificial intelligence (AI), as well as for providers of documentation services.

Key draft EU GMP Chapter 4 changes

Draft EU GMP Chapter 4 indicates several additional changes pharmaceutical manufacturers must be prepared for. These include:

Electronic data

Not surprisingly, expect increased scrutiny on electronic records, including electronic signatures, audit trails, access controls and data backup and recovery. The new rules officially acknowledge electronic signatures for the first time. E-signatures must be fully recognized- legally binding, traceable and compliant with ALCOA++ principles.

Data governance

Regulators will want to see that pharmaceutical companies are maintaining data governance in all aspects of their operation. Documentation systems are expected to be established taking data governance into account, reinforcing the life cycle of the data, considering data risk and critical nature, maintaining service provider oversight and ownership accountability throughout the data lifecycle.

Validation Master Plan

Draft EU GMP Chapter 4 requires a new mandatory master document: the Validation Master Plan. (Section 4.27) This document must detail and describe the key elements of the site qualification and validation program.

Employee training

There is specific emphasis on providing comprehensive training for personnel that ensures their understanding of proper data governance, including data integrity principles and practices. Expect regulators to request documentation of this training.

Manufacturing instructions

Chapter 4 revisions tighten manufacturing instructions in an effort to ensure batch-to-batch consistency and manufacturing reproducibility. This aligns with the U.S. Food and Drug Administration (FDA) process validation lifecycle approach as well as ICH Q7.

Standard Operating Procedures (SOPs)

While the core purpose of an SOP remains providing clear, repeatable instructions, the new guidance calls for the inclusion of both performing and recording operations. In the past, emphasis has only been on performing operations.

Records changes

Records under the proposed revisions now call for the inclusion of raw data and distribution information, underpinning regulators’ expectations for traceability.
