Eye on FDA

On September 3, 2025, the Food and Drug Administration (FDA) announced Rare Disease Evidence Principles (RDEP) with processes aimed at providing greater predictability and facilitating the development and review of drugs intended to treat rare diseases with very small patient populations and significant unmet medical needs driven by a known genetic defect. In conjunction with the agency’s announcement of the new processes jointly proposed by the Center for Drug Evaluation and Research (CDER) and Center for Biologics Evaluation and Research (CBER), the agency also unveiled additional information regarding eligibility and the potential for post-marketing requirements for those sponsors who participate in it.

Food dye reform has been an area of focus for the Trump administration as part of its Make America Healthy Again (MAHA) initiative, giving momentum to an effort the Food and Drug Administration (FDA) had already started by banning Red No. 3 for use in food and ingested drugs. FDA has continued to prioritize this work by taking actions to phase out the use of synthetic dyes and move to natural dyes since calling for these changes earlier this year, as discussed in our previous blog on the related announcement by the administration.

Last week, former Food and Drug Administration (FDA) Commissioner David Kessler submitted a citizen petition urging FDA to revoke the generally recognized as safe (GRAS) status of refined carbohydrates used in industrial food processing. The petition follows FDA’s and the United States Department of Agriculture’s (USDA) joint request for information (RFI) to establish a formal definition for ultra-processed foods (UPFs) and offers FDA a legal pathway to change the regulatory status of these ingredients.

Yesterday, the White House’s Make America Healthy Again (MAHA) Commission, led by the Department of Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. released its inaugural health report titled, Make Our Children Healthy Again, delivering one of the first widely anticipated deliverables from the MAHA Commission Executive Order issued earlier this year and noted in our prior alert. The 72-page assessment examines the rising rates of childhood chronic disease in the country—including obesity, heart disease and diabetes—and explores potential contributing factors. Specifically, the report identifies and focuses on four potential drivers:

In the last two weeks, the Department of Health and Human Services (HHS) has filled key artificial intelligence (AI) positions at HHS and the U.S. Food and Drug Administration (FDA). These appointments, as well as recent statements from HHS and FDA leadership, align with the Trump administration’s intention to use AI to improve regulatory efficiency at HHS and beyond.

On April 10, 2025, the Food and Drug Administration (FDA) announced its plan to replace animal testing in the development of monoclonal antibody therapies and other drugs in one of the first announcements by the agency since Commissioner Makary was confirmed to lead it. In its announcement, FDA highlighted that this more modern approach is designed to improve drug safety and accelerate the evaluation process, while also reducing animal experimentation, lowering research and development costs, and lowering drug prices.

In the past week, the U.S. Food and Drug Administration (FDA), in collaboration with the Department of Health and Human Services (HHS) announced three new initiatives related to food safety and food supply chain transparency. Outlined below, these new initiatives align with HHS Secretary Robert F. Kennedy Jr.’s recent announcements to focus on bolstering food safety, including the recent directive to the FDA to explore the revision of the longstanding Generally Recognized as Safe (GRAS) rule.

On January 6, the FDA announced the availability of draft guidance on accelerated approval for drugs and biological products, and consideration for determining whether a confirmatory trial is underway. Under the Consolidated Appropriations Act, 2023, Congress gave the FDA the authority to require that a confirmatory trial be underway prior to the granting of accelerated approval or within a specific time period after the date of accelerated approval. This latest guidance comes on the heels of the accelerated approval guidance issued by the agency just last month (see prior analysis here), in which the agency stated its intent to address the 2023 authority in a separate guidance.

On January 6 and 7, 2025, the FDA announced, by our count, 31 draft or final guidances, on a wide range of topics. Historically, an incoming administration will impose a temporary freeze on the issuance of guidances and rules, and might ultimately have different policy priorities and goals than the previous administration. Thus, the release of these numerous new guidances reflects topics that the FDA likely views as particularly important to address.
