FDA Issues New Rules for Testing Horse Worm Medicine

2026-14073, Drug Establishment Registration and Drug Listing Requirements for Establishments Engaged in Distributed Manufacturing and Certain Foreign Establishments

The FDA wants to make it easier for drug makers who work in several locations to register as one company instead of many. They’re also updating rules for foreign drug companies to match new laws about handling health threats. If you’re in drug manufacturing, get ready to comment by September 11, 2026, and keep an eye on possible paperwork changes that could affect your business.

2026-13047, Establishment Registration and Product Listing for Tobacco Products

The FDA wants to make sure all tobacco product makers, both in the U.S. and abroad, register their businesses and list their products.

Comments on this proposal are open until September 14, 2026, so affected businesses should get ready to update their info and possibly face new costs.

2026-15963, Medical Devices; Radiology Devices; Classification of the Fludeoxyglucose F18-Guided Radiation Therapy System

The Food and Drug Administration (FDA) is classifying the fludeoxyglucose F18-guided radiation therapy system into class II (special controls). The special controls that apply to the device type are identified in this order and will be part of the codified language for classification of the fludeoxyglucose F18-guided radiation therapy system. We are taking this action because we have determined that classifying the device into class II will provide a reasonable assurance of safety and effectiveness of the device. We believe this action will also enhance patients' access to beneficial innovative devices, in part by reducing regulatory burdens.

2026-15964, Authorization of Emergency Use of an In Vitro Diagnostic Device in Response to an Outbreak of Mpox; Availability

The Food and Drug Administration (FDA or Agency) is announcing the issuance of an Emergency Use Authorization (EUA) (the Authorization) under the Federal Food, Drug, and Cosmetic Act (FD&C Act) in response to an outbreak of Mpox. FDA has issued an Authorization for an in vitro diagnostic device, Allplex HSV-1&2/VZV/ MPXV Assay, for the simultaneous qualitative detection and differentiation of viral nucleic acid from monkeypox virus (MPXV clade I/II and MPXV clade II)1, herpes simplex virus type 1 (HSV-1), herpes simplex virus type 2 (HSV-2), and varicella-zoster virus (VZV). The Authorization contains, among other things, conditions on the emergency use of the authorized product. The Authorization follows the August 9, 2022, determination by the Secretary of Health and Human Services (HHS) that there is a public health emergency, or a significant potential for a public health emergency, that affects, or has a significant potential to affect, national security or the health and security of U.S. citizens living abroad, and that involves monkeypox virus. On the basis of such determination, the Secretary of HHS declared, on September 7, 2022, that circumstances exist justifying the authorization of emergency use of in vitro diagnostics for detection and/or diagnosis of infection with the monkeypox virus, including in vitro diagnostics that detect and/or diagnose infection with non-variola Orthopoxvirus, pursuant to the FD&C Act, subject to terms of any authorization issued under that section. The Authorization, which includes an explanation of the reasons for issuance, is listed in this document, and can be accessed on FDA's website from the link indicated.

We are also providing notice that the administrative stay of the effective date for the repeal and delisting of the color additive regulations is now lifted.
