Eye on FDA

On March 20, 2026, the Food and Drug Administration (FDA) announced the agency will hold a public hearing on the Commissioner’s National Priority Voucher (CNPV) Pilot Program, with a Federal Register notice soliciting public comment and scheduling a public hearing for June 12, 2026. As previously noted here and here, the program was announced in June 2025 for the purpose of providing select sponsors with a nontransferable voucher for enhanced engagement with FDA and expedited review for drugs and biologics supporting one or more critical national health priorities, while maintaining adherence to the law’s rigorous safety and effectiveness standards. The national health priorities include public health crisis response, innovative breakthrough therapies, large unmet medical needs, onshoring and supply chain resilience initiatives, and affordability improvements. To date, FDA has issued 18 Commissioner’s National Priority vouchers and approved four products to receive these vouchers, including two oncology drugs 44 and 55 days after filing.

On March 9, 2026, the Food and Drug Administration (FDA) published a draft guidance, “Responding to FDA Form 483 Observations at the Conclusion of a Drug CGMP Inspection.” The guidance is intended for foreign and domestic human and animal drug establishments manufacturing drugs regulated by the Center for Drug Evaluation and Research (CDER), the Center for Biologics Evaluation and Research (CBER) and the Center for Veterinary Medicine (CVM). The guidance is also intended for combination product manufacturers for which CDER or CBER is the lead center.

On February 23, 2026, the Food and Drug Administration (FDA) released a draft guidance entitled “Considerations for the Use of the Plausible Mechanism Framework to Develop Individualized Therapies that Target Specific Genetic Conditions with Known Biological Cause.” This guidance is designed for targeted, individualized therapies for which randomized controlled trials are not practical due to a small patient population, and was previewed by the Commissioner in several public forums.

On February 1, 2026, the Food and Drug Administration (FDA) officially started accepting requests to participate in the FDA PreCheck pilot program. The goal of the program is to strengthen the domestic pharmaceutical supply chain by making the review and inspection process more predictable for U.S.-based drug manufacturing facilities.

Last week, FDA released draft guidance titled “Scientific Considerations in Demonstrating Biosimilarity to a Reference Product: Updated Recommendations for Assessing the Need for Comparative Efficacy Studies.” This draft guidance reflects an evolution in FDA’s approach to determining whether a comparative clinical study with efficacy endpoints (a comparative efficacy study or CES) is necessary to support a demonstration of biosimilarity. Specifically, the agency notes that a comparative analytical assessment (CAA) is generally more sensitive when it comes to detecting differences between products than a CES.

On October 16, 2025, the Food and Drug Administration (FDA) unveiled the first group of nine voucher recipients under the Commissioner’s National Priority Voucher (CNPV) pilot program, a program announced by the agency earlier this year that provides a path for accelerated drug review for companies supporting national interests as determined by the Commissioner. The identified areas of priority by the agency include meeting large unmet medical needs, bolstering domestic manufacturing and increasing the affordability of medicines for American patients. As previously noted, the new program, which is not defined in statute or regulations, aims to significantly speed up FDA’s standard 10-12 month review timeline to just 1-2 months after filing an application for a drug or biologic. The agency has touted the  benefit of recipients of the vouchers receiving enhanced access with FDA review staff and a “team-based review” model.
