21 CFR Part 11 is a crucial component of regulatory compliance in clinical trials and, more broadly, any industry subject to the regulations of the U.S. Food and Drug Administration (FDA). Its central focus is electronic records and signatures. These rules serve as a regulatory benchmark, allowing digital transactions to be as trustworthy and reliable as paper ones.

This blog post will serve as a comprehensive guide to understanding and implementing 21 CFR Part 11 compliance in your clinical trials. Let’s explore.

What is 21 CFR Part 11?

The Title 21 Code of Federal Regulations Part 11, or 21 CFR Part 11, is a regulation set forth by the FDA, which applies to all industries under its regulation, including pharmaceuticals, medical devices, biotechnology, and other life sciences. Specifically, it outlines the criteria under which electronic records and electronic signatures are considered trustworthy, reliable, and equivalent to paper records and handwritten signatures.

The regulation was established in 1997 to address the FDA’s concerns regarding the use of electronic records and signatures, ensuring their integrity, accuracy, and confidentiality.

Key Components of 21 CFR Part 11

21 CFR Part 11 comprises three key areas of concern: electronic records, electronic signatures, and audit trails.

1. Electronic Records: The regulation applies to any electronic records created, modified, maintained, archived, retrieved, or transmitted under any records requirements set forth by the FDA. The purpose is to ensure that the records are authentic, accurate, and secure.

2. Electronic Signatures: 21 CFR Part 11 requires that electronic signatures have the same impact as traditional handwritten signatures. The regulation outlines requirements for using electronic signatures, such as unique identification codes and two distinct identification components.

3. Audit Trails: An audit trail is a secure, computer-generated, time-stamped record that allows for the reconstruction and examination of the sequence of environments and activities surrounding or leading to an operation, procedure, or event in a transaction from its inception to the final result.

21 CFR Part 11 and Clinical Trials

In the context of clinical trials, 21 CFR Part 11 compliance ensures that electronic records, including case report forms (CRFs), trial master files (TMFs), and electronic data capture (EDC) systems, are secure, traceable, and reliable.

Compliance with this regulation is of paramount importance, not just for regulatory reasons but also for ensuring the validity of clinical trial data and protecting patient safety.

How to Ensure Compliance

Here are some steps to ensure your clinical trial complies with 21 CFR Part 11:

1. Understand the Scope: First and foremost, understand the electronic systems you use and determine which records are subject to 21 CFR Part 11.

2. Implement Secure Systems: Invest in software and hardware systems that provide secure access control, audit trail capabilities, and electronic signature features.

3. Develop SOPs: Create Standard Operating Procedures (SOPs) outlining the correct use of electronic systems. SOPs should cover system validation, system maintenance, data backup, security measures, and training for employees.

4. Regular Training: Regularly train employees on the importance of compliance with 21 CFR Part 11 and how to maintain it.

5. Regular Auditing: Conduct routine audits of your electronic systems to verify their compliance with 21 CFR Part 11.

6. System Validation: Perform system validation to ensure that electronic systems are capable of producing accurate, reliable results consistent with the intended use.

Electronic Records: Ensuring Authenticity and Integrity

When discussing electronic records, 21 CFR Part 11 emphasizes their authenticity, integrity, and confidentiality. For an electronic record to be compliant, it needs to be trustworthy and reliable over its entire lifecycle, from creation and modification to maintenance, archival, retrieval, and transmission.

In clinical trials, examples of electronic records include electronic case report forms (eCRFs), lab results, medical images, trial protocols, informed consent forms, and adverse event reports.

One of the best ways to ensure electronic records’ reliability is to implement digital safeguards, such as access controls (like password protection) and encryption technologies. Also, the data generated should be subjected to regular backups and archiving in secure, tamper-evident systems to prevent data loss.

Electronic Signatures: Safeguarding Identity

Electronic signatures in the context of 21 CFR Part 11 aren’t just digitized versions of handwritten signatures. They must be unique to the individual, and it must be ensured that they can’t be repudiated.

In the clinical trial realm, investigators, clinical study coordinators, and even participants may need to provide electronic signatures on various documents such as eCRFs, trial protocol agreements, or electronic informed consent forms. To comply with 21 CFR Part 11, electronic signature systems should incorporate two distinct identification components (e.g., a combination of a password and a unique identification code).

Audit Trails: Tracing the Path

Audit trails play a critical role in the regulatory landscape of clinical trials. They ensure that any action performed on an electronic record can be traced back to the individual who performed it. This not only assures the integrity of the data but also maintains accountability.

To comply with 21 CFR Part 11, audit trails should capture the date and time of the action, the identity of the individual who performed it, and details of the changes made. Notably, the audit trail itself should be protected from modifications and should be readily available for review or audit by a regulatory authority.

Validation: Building Trust in Systems

System validation is a significant aspect of 21 CFR Part 11. It refers to the process of evaluating a system during its development and operation to ensure that it functions as intended. For clinical trials, system validation helps to confirm that the electronic systems used for data capture, storage, and analysis are reliable and capable of producing accurate results.

Validation should occur at several stages, including when a new system is implemented, when significant changes are made to an existing system, and periodically throughout the system’s use.

Systems Require Compliance

There are many systems used in clinical trials and other FDA-regulated environments that may require adherence to 21 CFR Part 11. Here’s a non-exhaustive list of such systems:

1. Electronic Data Capture (EDC) Systems: These systems are commonly used to collect clinical trial data in a digital format, replacing the traditional paper-based data collection methods.

2. Clinical Trial Management Systems (CTMS): These systems help manage and streamline different stages of clinical trials, including patient enrollment, tracking milestones, and managing study costs.

3. Electronic Trial Master File (eTMF) Systems: These systems digitally store, organize, and manage the critical documents and data that comprise a Trial Master File in a clinical study.

4. Electronic Patient Reported Outcomes (ePRO) Systems: These systems capture patient-reported data in clinical trials digitally, often through devices like smartphones or tablets.

5. Electronic Informed Consent (eConsent) Systems: These systems manage the process of obtaining and documenting participant consent in clinical trials digitally.

6. Electronic Health Record (EHR) Systems: These systems digitally store a patient’s medical history and can often be integrated with other systems for a more streamlined data flow.

7. Interactive Response Technology (IRT) Systems: These systems manage patient interactions and the logistics of medication inventory in clinical trials.

8. Laboratory Information Management Systems (LIMS): These systems manage the collection, processing, storage, and retrieval of laboratory data.

9. Pharmacovigilance and Safety Systems: These systems are used to collect, assess, and report adverse events during a clinical trial to ensure patient safety.

10. Quality Management Systems (QMS): These systems manage a company’s quality policy and objectives, ensuring that processes are controlled and outcomes are reliable.

11. Regulatory Information Management (RIM) Systems: These systems manage regulatory submission processes and timelines, ensuring that all regulatory requirements are met.

12. Learning Management Systems (LMS): These systems may be used in clinical research organizations to train employees on various procedures, including 21 CFR Part 11 compliance.

It’s important to note that whether a system must be 21 CFR Part 11 compliant depends on how it’s being used. If a system is used in a way that creates, modifies, maintains, archives, retrieves, or transmits electronic records that are subject to FDA regulations, then it will need to be 21 CFR Part 11 compliant.

How to audit each of these systems on whether they meet compliance?

Auditing your systems for compliance with 21 CFR Part 11 is a critical process that helps ensure the integrity and reliability of your electronic records and signatures. Here’s how you might approach auditing each of the systems mentioned above:
