Abstract
The regulatory landscape for precision oncology in the United States is complicated, with multiple governmental regulatory agencies with different scopes of jurisdiction. Several regulatory proposals have been introduced since the Food and Drug Administration released draft guidance to regulate laboratory developed tests in 2014. Key aspects of the most recent proposals and discussion of central arguments related to the regulation of precision oncology laboratory tests provides insight to stakeholders for future discussions related to regulation of laboratory tests.

The current regulatory environment in the United States
The current state of laboratory test regulation in the United States (U.S.) is complex, and the prospect of changes in the current paradigm has been continually on the horizon since 2014. Briefly, clinical laboratories in the U.S. are regulated under the Clinical Laboratory Improvement Amendments of 1988 (CLIA ′88)[1] of the Public Health Services Act, which are administered by the Centers for Medicare and Medicaid Services (CMS). These regulations were put in place to improve the quality of the processes in clinical laboratories, but the regulations allow for organizations that have received certification from CMS to inspect laboratories as a deemed entity. This status allows deemed entities to place additional requirements in place, so long as the underlying CLIA requirements are met.
CLIA regulations have a flexible framework that allows individual medical directors and laboratories to have some leeway in how the specific requirements are met, which allows for accommodation of unique population-, laboratory-, and test-level factors that can improve the overall quality of testing, while also allowing for the development of tests by laboratory medicine practitioners within certain bounds. Testing kits that are manufactured and shipped across state lines are regulated by the U.S. Food and Drug Administration (FDA) via the Medical Device Amendments of 1976[2], which amended the Federal Food, Drug, and Cosmetic Act of 1938. The FDA has several review and approval pathways where the manufacturer submits documentation and data to the FDA for review, and if the data fulfill the FDA’s requirements, the test recieves marketing authorization. Manufacturers can then sell their products to laboratories, who wish to perform that testing.
Testing kits which are cleared or approved by the FDA are regulated under CLIA when they are performed in a certified laboratory. In addition, under the current structure, laboratories are expected to verify the performance of these products and, under CLIA, are allowed to modify them if deemed necessary by medical leadership. If a manufactured product is modified by the user's laboratory, the test is considered a "laboratory developed test." Such modifications are frequently made to improve assay performance, use the assay in a way different from the use claimed by the manufacturer (e.g., diagnostic instead of screening applications), or allow acceptance of additional sample types that were not submitted to the FDA for approval. This regulatory flexibility allows clinical laboratories to offer tests that are accurate and medically relevant to their patients. Currently, many high-complexity clinical laboratories are accredited by the College of American Pathologists (CAP), which conducts unannounced biannual laboratory inspections and administers a multitude of proficiency testing programs to evaluate the accuracy and agreement between laboratories across the spectrum of laboratory tests.
The FDA has maintained that they have the statutory authority to regulate all laboratory tests, including tests that are developed and offered in a single lab, but have chosen to operate under a policy of enforcement discretion.
