On May 12, 2025, President Trump signed an Executive Order (“EO” or “Order”) “Delivering Most-Favored-Nation Prescription Drug Pricing to American Patients” aimed at significantly reducing U.S. prescription drug prices by aligning them with the lowest prices paid by other developed nations. According to the EO, drug manufacturers “deeply discount their products to access foreign markets and subsidize that decrease through enormously high prices in the United States.” Seeking to rectify this “egregious imbalance,” the EO announced the following policy: “Americans must therefore have access to the most-favored-nation price for these products… [and] should drug manufacturers fail to offer American consumers the most-favored-nation lowest price, [the] Administration will take additional aggressive action.”
Missed PDUFA Targets: Context, Concerns, and the Case of Stealth BioTherapeutics
The FDA’s commitment to timely drug approvals under the Prescription Drug User Fee Act (PDUFA) has been a cornerstone of its regulatory framework. Historically, the agency has maintained a high success rate in meeting its PDUFA goals; however, a handful of delays will typically occur each year for largely idiosyncratic reasons. Since 2021, when the FDA experienced delays due to challenges during the COVID-19 pandemic, the FDA has generally met or exceeded 90% of its review performance goals for new drug applications (NDAs) and biologics license applications (BLAs). However, recent regulatory upheaval at the FDA has prompted discussions of a potential decline in the previously reliable response rates and the implications for biotech companies and patients awaiting new therapies.
FDA’s Roadmap to Reducing Preclinical Animal Safety Studies: Six Things to Know
On April 10, 2025, the U.S. Food and Drug Administration (FDA) announced a new initiative to explore ways to reduce preclinical animal safety studies for human drugs and biological products, beginning with an approach to allowing the use of “New Approach Methodologies” (NAMs) in lieu of animal testing for eligible investigational monoclonal antibodies.[1] The agency’s plan marks a significant departure from decades of agency practice, in which life sciences companies developing novel therapeutic products typically have conducted a number of safety studies, including pharmacological and toxicological studies, in various species before progressing to the clinical phase. Below are six key points for life sciences companies to know about FDA’s plans to incorporate NAMs into preclinical evaluations for human drugs and biologics.
FDA’s User Fee Programs at a Crossroads: User Fee Deadlines and Funding at Risk
Gibson Dunn is closely monitoring developments and is prepared to help companies consider and address the implications of potential changes to FDA’s funding structure and authorities, including through regulatory counseling, agency and legislative engagement, and litigation.
Following recent mass layoffs at the Food and Drug Administration and growing criticism from senior administration officials of FDA’s user fee funding programs, the life sciences industry can expect significant changes to both FDA’s ability to meet medical product user fee deadlines and the future of the user fee programs more broadly.
FDA in Flux: What Life Science Companies Should Expect as the Agency Undergoes Staffing Changes
The beginning of the second Trump administration has been marked by significant—and often sudden—efforts to shrink the federal workforce and replace agency leadership to establish and deliver on a new set of priorities. In the past weeks, the administration has pursued a deferred resignation program,[1] terminated employees both in leadership and on probationary status,[2] and announced plans for a forthcoming government-wide reduction in force.[3] The U.S. Food and Drug Administration (FDA) has not been immune to these changes.
Life Sciences 2025 Outlook
The life sciences industry is entering 2025 with a largely favorable set of catalysts for the coming year, but also with some larger risks that will impact companies differently.
FDA to Require Confirmatory Trials Be “Underway” Prior to Accelerated Approval, Per New Draft Guidance
Life sciences companies interested in pursuing accelerated approval should ensure they have a thorough understanding of the complex regulatory landscape and engage in early discussions with FDA regarding their drug development programs.
FDA Issues Overdue Guidance on Diversity Action Plans in Drug and Device Clinical Trials – What You Need to Know
This update provides key takeaways on the new draft guidance and Diversity Action Plan requirements, including when the new requirements will go into effect, the types of clinical studies that require submission of a Diversity Action Plan, whether FDA intends to issue waivers for the requirements, and the consequences of failure to submit a Diversity Action Plan.
