1. What Was the FDA’s Stance on Laboratory Developed Tests (LDTs) in 2018?

In 2018, the FDA was actively discussing increased oversight of Laboratory Developed Tests (LDTs) to ensure their safety and effectiveness, recognizing the growing concerns about these tests. The FDA’s focus stemmed from the increasing use of IVDs offered as LDTs in healthcare decisions and the potential harm from inaccurate test results. Let’s explore the background and the reasons behind this regulatory scrutiny.

Background of FDA’s Concerns with LDTs

LDTs, which are in vitro diagnostic products (IVDs) designed, manufactured, and used within a single laboratory certified under CLIA, play a significant role in healthcare. These tests analyze specimens like blood, saliva, or tissue to detect substances such as proteins, glucose, cholesterol, or DNA, providing crucial information for diagnosis, monitoring, and treatment of diseases.

However, the FDA had long exercised enforcement discretion for most LDTs, meaning they generally didn’t enforce applicable requirements. This approach was acceptable when LDTs were lower risk, used in small volumes, and catered to specialized needs of local populations. Over time, the landscape changed dramatically. Business practices evolved, specimens could be shipped across the country quickly, and LDTs became more widely used for larger, more diverse populations. These tests also began to rely on advanced technology, high-tech instrumentation, and software, making them integral in critical healthcare decisions.

The FDA recognized that the risks associated with modern LDTs far exceeded those of the past. False test results or inaccurate claims about test results could lead to significant patient harm. To address these concerns, the FDA began phasing out its general enforcement discretion approach for LDTs, aiming to ensure their safety and effectiveness while considering public health considerations such as patient access and reliance.

Increased FDA Oversight to Ensure Safety and Effectiveness

The FDA’s move towards increased oversight of LDTs was driven by the need to protect patients and healthcare providers who rely on these tests to make informed decisions. Without active FDA oversight, assurances about the safety and effectiveness of IVDs offered as LDTs were lacking. The FDA engaged in discussions, workshops, draft guidance documents, and interactions with congressional and industry stakeholders to address these issues.

For instance, a study by Johns Hopkins University published in JAMA in 2016 highlighted significant concerns regarding the accuracy and reliability of LDTs used for cancer diagnosis. The study found that many LDTs lacked sufficient clinical validation, potentially leading to incorrect treatment decisions and adverse patient outcomes.

The FDA’s proposed rule, issued on October 3, 2023, and finalized on April 29, 2024, explicitly stated that IVDs are devices under the Federal Food, Drug, and Cosmetic Act, even when manufactured by a laboratory. This rule included a phaseout policy to provide greater oversight of IVDs offered as LDTs over four years, with targeted enforcement discretion policies for certain categories of IVDs manufactured by laboratories.

By increasing its oversight, the FDA aimed to ensure that all LDTs meet the necessary safety and effectiveness standards, reducing the risk of patient harm and improving the overall quality of healthcare. This approach reflects a commitment to adapting regulatory frameworks to address the evolving challenges in diagnostic testing.

2. How Did the FDA’s Final Rule Impact Laboratory Developed Tests (LDTs)?

The FDA’s final rule, issued on May 6, 2024, significantly impacted Laboratory Developed Tests (LDTs) by clarifying that in vitro diagnostic products (IVDs) are considered devices under the Federal Food, Drug, and Cosmetic Act (FD&C Act), even when a laboratory manufactures them. This rule initiated a phaseout of the FDA’s general enforcement discretion approach for LDTs over four years. Let’s delve deeper into the details of this transformative rule.

Key Components of the Final Rule

The final rule includes several critical components:

1. Reclassification of IVDs as Devices: The rule explicitly states that IVDs, including those offered as LDTs, fall under the definition of devices as defined in the FD&C Act. This reclassification brings LDTs under the FDA’s regulatory authority, ensuring they are subject to the same standards as other medical devices.

2. Phaseout of Enforcement Discretion: The FDA is phasing out its long-standing policy of general enforcement discretion for LDTs over a four-year period. This means that LDTs will gradually be required to comply with applicable FDA requirements, such as premarket review, quality system regulations, and labeling requirements.

3. Targeted Enforcement Discretion Policies: While the FDA is phasing out general enforcement discretion, it will implement targeted enforcement discretion policies for certain categories of IVDs manufactured by laboratories. These policies consider the specific characteristics and risks associated with different types of LDTs, allowing for a more flexible and risk-based approach to regulation.

Stages of the Phaseout Policy

The phaseout policy consists of five stages, each introducing new compliance requirements for LDTs:

• Stage 1 (beginning May 6, 2025): Compliance with medical device reporting (MDR) requirements, correction and removal reporting requirements, and quality system (QS) requirements regarding complaint files.
• Stage 2 (beginning May 6, 2026): Compliance with requirements not covered in other stages, including registration and listing requirements, labeling requirements, and investigational use requirements.
• Stage 3 (beginning May 6, 2027): Compliance with QS requirements (excluding those related to complaint files, which are addressed in Stage 1).
• Stage 4 (beginning November 6, 2027): Compliance with premarket review requirements for high-risk IVDs offered as LDTs (classified into Class III or subject to licensure under Section 351 of the Public Health Service Act). Enforcement discretion will continue if a premarket submission is received by this stage.
• Stage 5 (beginning May 6, 2028): Compliance with premarket review requirements for moderate-risk and low-risk IVDs offered as LDTs (requiring premarket submissions). Enforcement discretion will continue if a premarket submission is received by this stage.

Impact on Laboratories and Healthcare Providers

The FDA’s final rule has significant implications for laboratories and healthcare providers:

• Increased Compliance Burden: Laboratories offering LDTs face a greater compliance burden as they must adhere to FDA regulations. This includes implementing quality systems, conducting premarket reviews, and complying with reporting requirements.

• Potential for Innovation: The rule could foster innovation by ensuring that LDTs are safe and effective, leading to more reliable diagnostic tools. Clear regulatory pathways can encourage laboratories to invest in research and development of new and improved tests.

• Patient Safety: The rule aims to enhance patient safety by reducing the risk of inaccurate or unreliable test results. By requiring LDTs to meet FDA standards, patients and healthcare providers can have greater confidence in the accuracy and clinical validity of these tests.

• Access to Tests: Some stakeholders have raised concerns about potential limitations on access to LDTs, particularly for rare diseases or specialized diagnostic needs. However, the FDA’s targeted enforcement discretion policies are intended to address these concerns by allowing flexibility for certain categories of LDTs.

For example, the American Clinical Laboratory Association (ACLA) has expressed concerns about the potential impact of the final rule on laboratory operations, particularly for smaller laboratories that may lack the resources to comply with all FDA requirements. However, patient advocacy groups have generally supported the rule, emphasizing the importance of ensuring the accuracy and reliability of LDTs.
