On February 18, 2026, FDA Commissioner Martin Makary and Vinay Prasad, then-Chief Medical and Scientific Officer and Director of the Center for Biologics Evaluation and Research, published a landmark policy announcement in the New England Journal of Medicine that a single adequate and well-controlled pivotal trial — supplemented by confirmatory evidence — is now the FDA’s default standard for approving novel drugs.[1] The agency’s longstanding practice of requiring two pivotal trials has not been a statutory mandate since 1997: at that time, Congress amended the Federal Food, Drug, and Cosmetic Act to provide that data from one adequate and well-controlled trial and confirmatory evidence can constitute ‘substantial evidence’ of effectiveness.[2] In some therapeutic areas, such as in oncology and rare disease, FDA increasingly has approved drugs on the basis of a single clinical trial, but, as a matter of general agency policy, two trials have been the baseline norm for decades.[3] That norm has now changed.
MFN Drug Pricing in 2026: Voluntary Deals Are Giving Way to Mandatory Rules — Five Things Life Sciences Companies Need to Know
What began as a series of demand letters in July 2025 has evolved into something significantly more consequential. By February 2026, sixteen of the seventeen largest pharmaceutical manufacturers have signed Most-Favored-Nation (MFN) pricing agreements with the Trump administration, which commit them to Medicaid price parity, MFN pricing on new product launches, and participation in TrumpRx.gov in exchange for three-year tariff immunity and improved regulatory positioning. But as those voluntary deals settle, the Centers for Medicare & Medicaid Services (CMS) has moved to make MFN pricing mandatory for Medicare through two new models: GLOBE (Medicare Part B) and GUARD (Medicare Part D), both published in the Federal Register on December 23, 2025, with a public comment period that closed on February 23, 2026.
Getting Ready for Your Q3 Quarterly Reports: Updated Disclosure Regarding Tariffs and Government Shutdown
As public companies prepare their third quarter Form 10-Q filings, the rapidly shifting policy landscape has created new disclosure challenges for the life sciences sector. The recently announced pharmaceutical tariffs and ongoing government shutdown both carry potential financial and operational implications that warrant close attention. For biotech companies, these developments underscore the need for clear, proactive disclosure around supply chain resilience, pricing exposure, and regulatory uncertainty. In this post, we outline key disclosure considerations to help issuers navigate this evolving environment and manage investor expectations heading into the end of the year.
Getting Ready for Your Q2 Quarterly Reports: Trends in Biopharmaceutical Disclosures from Q1 Quarterly Reports
Earlier this year, the new Presidential Administration introduced a series of policies, legislative proposals and regulatory actions that have impacted the business and regulatory environment and contributed to a climate of uncertainty—particularly in the biopharmaceutical sector. These developments gave companies much to address in their first quarter 10-Q filings. To shed light on how biopharmaceutical companies addressed these developments, we conducted a survey of the Q1 Quarterly Reports of the top 100 biopharmaceutical companies. Our analysis revealed that most companies are actively assessing the potential impact of these changes, with more than two-thirds (68%) of companies updating their risk factors and more than half (53%) updating their Management’s Discussion & Analysis (MD&A) accordingly. Below is a summary of the key disclosure changes, with a focus on topics of heightened relevance to the industry—including tariffs, changes in laws related to Medicaid or Medicare, federal workforce disruptions and other issues such as the Section 232 investigation and the Section 340B Drug Pricing Program.
