FDA Releases Groundbreaking Guidance for Regulating AI-Enabled Medical Devices

The FDA's new guidance on predetermined change control plans aims to streamline the regulation of self-modifying AI-enabled medical devices, ensuring safety and efficacy.

This week, the U.S. Food and Drug Administration (FDA) captured attention with the publication of its eagerly awaited final guidance on predetermined change control plans (PCCPs) for devices utilizing artificial intelligence and machine learning (AI/ML) software.

The FDA’s initiative is designed to accelerate the development of safe and effective AI-powered devices, marking a critical step in adapting to the swift evolution of digital health technologies.

Navigating the Regulatory Landscape of AI

Regulating AI-enabled medical devices presents a significant challenge for the FDA, particularly when it comes to the software functions they employ, referred to as AI-DSF.

These functionalities can self-modify, which complicates the FDA’s established framework for overseeing medical devices.

Since the Medical Device Amendments were introduced in 1976, the FDA has enforced strict rules on post-market changes.

Manufacturers who receive 510(k) clearances, De Novo classifications, or premarket approvals (PMAs) need to notify the FDA of any modifications that could affect a device’s safety or efficacy.

However, the self-adjusting nature of AI-DSF calls for a fresh perspective.

The FDA has been considering this new approach since at least 2019, and after nearly six years of deliberation, the agency has now unveiled comprehensive guidance on the matter.

A New Framework for PCCPs

The recently released guidance recognizes that AI-DSF technology is inherently dynamic.

It aims to ensure that these devices remain safe and effective without requiring traditional post-market adjustments.

Instead of seeking clearance for each significant modification after a device has been brought to market, manufacturers of AI-DSF must now submit a PCCP during their initial marketing application—be it a 510(k), De Novo, or PMA submission.

During this pre-market assessment, the FDA will evaluate the PCCP to confirm the device’s safety and efficacy without necessitating further submissions for every planned change discussed in the PCCP.

Rather than examining each individual modification in real-time, the FDA will focus on the overall human-defined objectives that guide these self-modifications.

The guidance document emphasizes three crucial components that should be included in an AI-DSF PCCP: (i) a thorough description of anticipated device modifications, (ii) a clear methodology for developing, validating, and implementing these changes while maintaining ongoing safety (known as the Modification Protocol), and (iii) a careful assessment of the benefits and risks linked to the proposed modifications, referred to as the Impact Assessment.

Spanning 49 pages, this guidance provides an in-depth look at each vital element of the PCCP process.

Notably, though, the PCCP is only one part of the marketing submission—manufacturers must also consider several other critical factors.

Looking Ahead

The future of the FDA’s regulatory framework, especially regarding informal guidance like this update, hangs in the balance as a new administration vows to implement significant regulatory changes.

To help safeguard this new policy against being rolled back, the guidance meticulously records stakeholder feedback that influenced its development from 2019 to 2024.

Such detailed documentation is often reserved for formal rulemaking processes rather than less formal guidance.

Despite this, the fact that the conversation around regulating AI-DSF originated during a previous administration, along with the growing momentum for AI regulation in various sectors, indicates there may be bipartisan support for such initiatives.

Whether the new administration will choose to formalize this PCCP guidance through legislation or whether Congress will be called to establish AI-DSF regulations remains to be seen.

In the meantime, the guidance published by the FDA is active and manufacturers of AI/ML-integrated medical devices should begin to integrate the development of Modification Descriptions, Modification Protocols, and Impact Assessments into their product development workflows.
