Eye on FDA

FDA recently released two draft guidance documents for industry related to cell and gene therapy (CGT) products as the agency seeks to advance the efficient development and review of safe and effective CGT products and fulfill related commitments set forth in the 2022 reauthorization of the Prescription Drug User Fee Act (PDUFA VII). This latest guidance may be of particular interest to CGT developers and various patient groups.

On Tuesday, September 23, 2025, FDA published guidance titled “Consideration of Enforcement Policies for In Vitro Diagnostic Tests During a Section 564 Declared Emergency.” The guidance, a draft of which was published on May 6, 2024, specifies the factors that FDA intends to assess in deciding whether to issue an enforcement discretion policy with regard to in vitro diagnostics (IVD) manufacturers offering unapproved IVDs, among other devices, during a declared emergency. These factors include:

Last week, the U.S. Food and Drug Administration (FDA) issued a proposed rule to revoke the color additive listing for Orange B, a synthetic dye historically used on the casings and surfaces of frankfurters and sausages. This action is part of the broader “Make America Healthy Again” (MAHA) initiative to phase out petroleum-based foods from the American food supply by the end of 2026 and efforts to modernize the agency’s regulations.

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.

Over the weekend, the Department of Justice (DOJ) did not file an appeal of the U.S. District Court for the Eastern District of Texas’ decision to vacate and set aside the agency’s final rule on the regulation of laboratory developed tests (LDTs), titled Medical Devices; Laboratory Developed Tests (the LDT Rule). The LDT Rule would have required laboratories to ensure that their offered LDTs met medical device requirements under a multistage phase out of Food and Drug Administration’s (FDA) enforcement discretion policy. While the government’s decision not to appeal this ruling may not have been a surprise, questions remain as to how FDA plans to clarify its policy towards lab test offerings going forward.

On May 30, 2025, the Department of Health and Human Services released additional information regarding the Trump administration’s Fiscal Year (FY) 2026 budget request. The release of these FY26 budget materials is timely as Secretary Kennedy and the Food and Drug Commissioner Dr. Makary have started to testify before Congress on the FY26 budget and the House and Senate Appropriations Committees are moving forward with their annual appropriations work. Further still, the House Appropriations Committee’s Subcommittee on Agriculture, Rural Development, Food and Drug Administration, and Related Agencies is scheduled to markup their FY26 Ag-FDA Approps bill later this week.

This week, the U.S. Food and Drug Administration (FDA), in collaboration with the Department of Health and Human Services (HHS), announced a series of new measures to phase out all petroleum-based synthetic dyes in food by the end of 2026. This initiative is part of the broader “Make America Healthy Again” (MAHA) agenda aimed at bolstering food safety. Citing growing concerns about the potential role of petroleum-based food dyes in childhood diabetes, obesity, depression and attention-deficit/hyperactivity disorder (ADHD), the agency plans to establish a national standard and timeline for the food industry to transition to natural alternatives.

On March 31, 2025, Judge Sean D. Jordan of the U.S. District Court for the Eastern District of Texas issued an opinion and judgment in American Clinical Laboratory Association v. FDA. Judge Jordan’s decision vacates and sets aside the Food & Drug Administration’s (FDA) final rule, Medical Devices; Laboratory Developed Tests (the LDT Rule).¹ The LDT Rule would have required laboratories offering LDTs to meet medical device requirements. The preamble to the LDT Rule provided a multi-stage phase out of FDA’s enforcement discretion policy, under which the first set of regulatory requirements would have been actively enforced beginning May 6. While many labs are breathing a sigh of relief after the publication of this order, questions remain as to how the agency will proceed and the broader implications for regulation of lab tests and in vitro diagnostics generally.

In the final stretch of the Biden administration, the Food and Drug Administration (FDA) laid the groundwork for continued engagement with the public on two challenging areas of product development, each of which is of high interest to patients, clinical communities, industry stakeholders and policy-makers in Congress.
