Title 21 › Chapter CHAPTER 9— - FEDERAL FOOD, DRUG, AND COSMETIC ACT › Subchapter SUBCHAPTER V— - DRUGS AND DEVICES › Part Part A— - Drugs and Devices › § 360a–2
The law requires the Secretary of Health and Human Services to keep susceptibility test interpretive criteria for antimicrobial drugs up to date to protect public health as germs change and become resistant. The Secretary must pick the right criteria when a drug is approved or as soon as criteria become available. Those choices must be based on lab and clinical data, how the criteria relate to sickness and death from the infection, and any other useful evidence. The Secretary can use those criteria when clearing, classifying, or approving tests that report whether bacteria, fungi, or other microorganisms are susceptible to drugs. The Secretary must create and keep a public “Interpretive Criteria” website no later than 1 year after December 13, 2016. The site will list new or updated standards from recognized standards groups and any specific interpretive criteria the Secretary finds appropriate when no standard applies or a drug needs different criteria. The site must explain that the test results are lab (in vitro) findings and may not always predict clinical success, that approved drug labels show authorized uses, and other helpful notes. The Secretary must review recognized standards at least every 6 months, publish notices of recognition or withdrawal, and update the website. Drug labels already on the market must replace their printed interpretive criteria with a reference to the website within 1 year after the site is set up; new drug labels must use the website reference instead of listing criteria. The law also lets the Secretary allow marketing of antimicrobial susceptibility testing devices that use the recognized or listed criteria if the device meets labeling and other approval or clearance rules. Key defined terms include: susceptibility testing device, qualified infectious disease product, susceptibility test interpretive criteria (numeric values and categories like susceptible or resistant), antimicrobial drug (mainly systemic antibacterial or antifungal for humans), and interpretive criteria standard. The law does not change the usual evidence rules for approving drugs or devices.
