📌TL;DR
FDA Commissioner Marty Makary resigned on Tuesday after 13 months in the role. The resignation followed days of reporting that the White House had signed off on a plan to replace him. The final trigger was a disagreement over flavored e-cigarette authorization, which Makary opposed but was overruled on. Kyle Diamantas, deputy commissioner for food, has been named acting commissioner.
Three Senate-confirmed health positions are now vacant: FDA commissioner, CDC director, and surgeon general. HHS Secretary Robert F. Kennedy Jr. said "the search for a new Commissioner is already underway, and we will move forward with urgency."
European mid-sized pharma companies are snapping up U.S. biotechs at an accelerating pace, according to BioSpace. Chiesi (KalVista), Angelini (Catalyst), UCB (Candid, Neurona), and LEO Pharma (Replay) all announced deals in the past month.
New cardiovascular guidelines from the American Heart Association and American College of Cardiology call for more aggressive LDL reduction, focusing on maintaining low levels of two key lipoproteins. Merck and Amgen are doubling down on the opportunity.
⚡ Executive Takeaway
It's over. Makary tried to hold the center between the MAHA agenda and traditional FDA regulation, and in the end, neither side was satisfied. Harvard's Dr. Aaron Kesselheim told Democracy Now: "Nobody was happy with what he did." The final straw was e-cigarettes, not drugs. Makary opposed authorizing fruit-flavored vapes because of their appeal to young people. He was overruled. A source told CNN: "He doesn't want to approve youth-appealing flavors, but has been forced to by the powers that be." He resigned Tuesday, one day before he was scheduled to testify before the Senate on the FDA's proposed budget. CNBC reported that a senior administration official "couldn't point to one issue" but described "a buildup of many problems," including abortion policy. Kennedy praised Makary on social media but said the search for a replacement "is already underway." The practical impact on pharma is immediate: PDUFA reauthorization negotiations are underway, the CNPV program has active filings (Revolution Medicines, Lilly T2D), the Expedited IND pathway needs a champion, and the RTCT pilot is supposed to launch this summer. All of this is now in the hands of Kyle Diamantas, a food safety official with no drug development background. The industry's chief regulator is gone, and the three most important Senate-confirmed health positions in the country are sitting empty. 👉 Read Full Analysis
🔮 What To Watch
Acting Commissioner Diamantas: His first decisions on drug-related matters will signal whether the FDA's drug development agenda continues or shifts. He comes from the food side of the agency.
PDUFA Reauthorization: The Prescription Drug User Fee Act expires September 30, 2027. Negotiations with industry are underway. A leadership vacuum at the FDA complicates these discussions.
CNPV Program Continuity: Revolution Medicines and Lilly (Foundayo T2D) have CNPV filings planned. Whether the program continues operating during the transition is the immediate question.
Permanent Nominee: Kennedy said the search is underway. Stephen Hahn and Brett Giroir remain potential nominees. Confirmation requires Senate approval (Makary was confirmed 56-44).
ASCO (17 days): Revolution Medicines plenary session May 31.
🌍 Policy & Regulatory
Makary Resigns After 13 Months. Diamantas Named Acting Commissioner.
What Happened: FDA Commissioner Marty Makary resigned on Tuesday May 12, ending a turbulent 13-month tenure. The Washington Post reported the resignation came "after months of turmoil at the agency and White House staff last week signing off on a plan to replace him." Trump announced Kyle Diamantas as acting commissioner on Truth Social. Diamantas was elevated to be one of Kennedy's deputy secretaries and oversees the FDA's food program.
The Final Trigger: Multiple outlets reported that the immediate cause was Makary's opposition to authorizing fruit-flavored e-cigarettes. Trump had pledged to protect the vaping industry during the 2024 campaign. The FDA announced its first approval of fruit-flavored vapes shortly before Makary's departure. A source told CNN that Makary "doesn't want to approve youth-appealing flavors, but has been forced to by the powers that be." The New York Times reported that this conflict was "what ultimately prompted Makary's decision to resign."
The Broader Context: CNBC reported that the resignation reflected "a buildup of many problems" including abortion policy (mifepristone handling angered anti-abortion groups), internal dysfunction (former cancer regulator Dr. Richard Pazdur cited Makary's leadership as his reason for leaving), and mounting backlash from drugmakers, physicians, and patient groups on regulatory decisions including high-profile rejections of rare disease treatments. Axios noted that Makary's departure means three Senate-confirmed health positions are now vacant: FDA commissioner, CDC director, and surgeon general.
Executive Impact: Kennedy praised Makary on social media: "Marty, you took on entrenched interests, challenged the status quo, and never lost sight of the American people we serve." He added: "The search for a new Commissioner is already underway, and we will move forward with urgency." For the pharmaceutical industry, the concerns are practical. PDUFA reauthorization negotiations are active. The CNPV program has pending and planned applications. The Expedited IND pathway was Makary's signature legislative proposal. The Real-Time Clinical Trial pilot was supposed to launch this summer. Staff morale at the FDA had already "plummeted after layoffs and departures of career agency scientists" (CNBC). A prolonged leadership vacuum risks slowing regulatory decisions at a time when the industry is filing more applications than at any point in recent memory.
🏢 Corporate & Business Developments
European Mid-Caps Are Buying American Biotechs at an Accelerating Pace
BioSpace reported on Tuesday that mid-sized European drugmakers are "snapping up US biotechs" at an accelerating pace, with differing views on whether the activity represents "the rise of a new buyer class or a quirk of timing." Recent deals from European acquirers include:
Chiesi (Italy): KalVista $1.9B (hereditary angioedema, April 29)
Angelini (Italy): Catalyst Pharmaceuticals $31.50/share (neurology, May 8)
UCB (Belgium): Candid Therapeutics $2.2B (autoimmune TCE, May 12) + Neurona Therapeutics $1.15B (epilepsy, April 17)
LEO Pharma (Denmark): Replay gene therapy (rare dermatology, May)
Combined, European mid-cap acquirers have deployed more than $5.5B in announced deals in the past month. The drivers are similar to their U.S. counterparts: patent cliff pressure, pipeline gaps, and attractive biotech valuations. But the pattern is new. Historically, cross-border biopharma M&A has been dominated by mega-cap acquirers (Novartis, Roche, AstraZeneca, Sanofi). The emergence of Chiesi, Angelini, UCB, and LEO as active buyers signals that the M&A wave has broadened beyond the usual suspects.

New Guidelines Push for More Aggressive LDL Reduction
New cardiovascular guidelines from the American Heart Association and American College of Cardiology call for more aggressive management of LDL cholesterol, emphasizing sustained low levels of apolipoprotein B and LDL particles as key targets, according to BioSpace. Merck and Amgen are "doubling down" on the opportunity. Merck is advancing its PCSK9 program, and Amgen's Repatha franchise is positioned to benefit from broadened treatment recommendations. The guidelines could expand the addressable market for PCSK9 inhibitors and next-generation lipid-lowering agents significantly, particularly among patients who do not achieve adequate control on statins alone.
BridgeBio's Attruby Shows Survival Signal vs. Pfizer's Tafamidis in ATTR-CM
BioSpace reported that indirect comparisons between BridgeBio's Attruby and Pfizer's tafamidis products showed a numerical survival benefit with BridgeBio's drug in transthyretin amyloid cardiomyopathy (ATTR-CM). While indirect comparisons carry significant limitations, the data position Attruby as a potentially differentiated competitor in the ATTR-CM market. The class generates multi-billion dollar revenue for Pfizer and represents one of the fastest-growing segments in cardiovascular medicine.

🔓 BioMed Nexus Pro: Institutional Intelligence Brief
🧠 The Regulatory Vacuum: Updated Assessment
The situation is now worse than we outlined on Monday. On Monday, Makary's departure was planned but not executed. Now it is done. Here is the updated status of every key initiative:
CNPV Program: OPERATING but uncertain. Three NMEs approved (Foundayo, Otarmeni, plus Bizengri under accelerated review). Psychedelic CNPVs issued. Revolution Medicines and Lilly T2D filings are planned. Risk level elevated from MODERATE to HIGH. Diamantas has no track record on drug development decisions.
Expedited IND Pathway: STALLED. This was Makary's signature legislative proposal. Without a commissioner advocating for it in Congress, the proposal is unlikely to survive PDUFA negotiations. Risk level: VERY HIGH.
Real-Time Clinical Trial Pilot: UNCERTAIN. AstraZeneca and Amgen pilots are operational. Public comment period closes May 29. But the broader pilot launch planned for this summer requires leadership direction. Risk level: MODERATE to HIGH.
PDUFA Reauthorization: COMPLICATED. The Prescription Drug User Fee Act expires September 30, 2027. Industry negotiations are underway. A leadership vacuum at the FDA introduces uncertainty into fee structures, review timelines, and performance goals that affect every company filing an NDA or BLA.
FDA Staffing: CRITICAL. Former cancer regulator Dr. Richard Pazdur cited Makary's leadership as his reason for leaving. Multiple senior scientists departed during his tenure. Staff morale is described as having "plummeted." Rebuilding institutional expertise takes years, not months.
💊 The European Buyer Thesis
The emergence of European mid-caps as active U.S. biotech acquirers reflects a structural shift. These companies face the same pipeline pressures as mega-caps but with smaller balance sheets, making U.S. clinical-stage biotechs (which are priced well below 2021 highs) particularly attractive targets.
The pattern: European companies with established commercial franchises in specific therapeutic areas are acquiring U.S. biotechs to extend those franchises. UCB (immunology/neuroscience) bought Candid (autoimmune TCE) and Neurona (epilepsy cell therapy). Chiesi (rare disease) bought KalVista (HAE). Angelini (neurology) bought Catalyst (Lambert-Eaton). LEO Pharma (dermatology) bought Replay (gene therapy for genetic skin disease).
BioSpace noted "differing views on whether the activity represents the rise of a new buyer class or a quirk of timing." The consistency of the strategic logic across four different companies suggests this is structural, not coincidental. Expect more European mid-cap deals in H2 2026.
📊 Cardiovascular: The Next Growth Vertical
The updated AHA/ACC guidelines expand the population eligible for aggressive lipid management, particularly PCSK9 inhibitors (Repatha, Praluent) and emerging agents. BioSpace reported Merck and Amgen are "doubling down" on the opportunity.
The cardiovascular drug market has been quiet relative to oncology and GLP-1 in recent years. These guidelines could change that. If PCSK9 inhibitors move from specialty prescribing to broader primary care use, the revenue opportunity expands significantly. Amgen's Repatha and Regeneron/Sanofi's Praluent are positioned to benefit immediately. Next-generation lipid agents (inclisiran, bempedoic acid combinations) also gain relevance.
For our readers: cardiovascular is a vertical we have covered lightly in this series. With new guidelines, active pipeline investment from Merck and Amgen, and BridgeBio's ATTR-CM data challenging Pfizer, expect more CV coverage in the weeks ahead.
