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 February 3, 2026, the Consolidated Appropriations Act, 2026 (P.L. 119-75) became law and marked an important milestone in the bipartisan congressional effort to reauthorize the rare pediatric disease priority review voucher program. Section 6604 of this law extends the Food and Drug Administration’s (FDA) authority to issue priority review vouchers to encourage treatments for rare pediatric diseases through September 30, 2029.

On December 5, 2025, FDA announced its Technology-Enabled Meaningful Patient Outcomes (TEMPO) for Digital Health Devices Pilot, a new voluntary pilot that seeks to accelerate innovation and expand access to digital health devices for people living with chronic conditions. Under TEMPO, FDA will evaluate a new, risk-based enforcement approach that supports digital health devices intended for use to improve patient outcomes in cardio-kidney-metabolic, musculoskeletal and behavioral health conditions. Under the pilot, participating manufacturers may request that the agency exercise enforcement discretion for certain requirements, such as premarket authorization and investigational device requirements, while manufacturers collect and share real-world data demonstrating the device’s performance.

Last week, FDA released draft guidance titled “Scientific Considerations in Demonstrating Biosimilarity to a Reference Product: Updated Recommendations for Assessing the Need for Comparative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 23, 2025, FDA released its final guidance regarding Patient-Focused Drug Development: Selecting, Developing, or Modifying Fit-for-Purpose Clinical Outcome Assessments. The guidance is the third guidance in a four-part series of FDA guidance focused on patient-focused drug development (PFDD) that describe how stakeholders, such as patients, caregivers, researchers, medical product developers and others can submit patient experience data and other relevant information that can be used for medical product development and regulatory decision making.

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.

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.

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.

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.
