Biopharma’s weight loss warriors have led the news this week, with Structure Therapeutics and Rhythm Pharmaceuticals announcing new data. Structure delivered a “competitive profile” for its investigational GLP-1 pill compared to Eli Lilly’s orforglipron and Novo Nordisk’s oral Wegovy, BMO Capital Markets wrote to investors, after the candidate elicited 16.3% weight loss after 44 weeks in a Phase 2 trial. Rhythm was not as successful, announcing that Imcivree failed in a Phase 3 basket trial of various genetically driven obesities.

Meanwhile, Lilly and Novo made headlines outside of the clinical realm, as Lilly warned the public of the potential safety risks of taking compounded versions of tirzepatide—marketed as Zepbound for obesity and Mounjaro for type 2 diabetes. And Novo was hit with an FDA warning letter for failing to investigate reported adverse events—including three deaths—potentially linked to its own diabetes drug Ozempic. The letter only adds to what has been a challenging recent run for Novo, one that led to a 34% drop in total assets under management for its controlling shareholder Novo Holdings.

On the regulatory front, Robert F. Kennedy Jr.’s vaccine agenda is stalled after Massachusetts District Court Judge Brian Murphy found that his efforts to overhaul policies in this area were likely unlawful. Murphy specifically cited Kennedy’s move last June to empty the CDC’s Advisory Committee on Immunization Practices (ACIP). This comes on the heels of a White House crackdown in which officials would like the health secretary to tone down his vaccine skepticism, according to a report by The Wall Street Journal.

At the FDA, tensions continue to escalate, with Sen. Ron Johnson (R-WI) launching an investigation into recent rejections of rare disease drugs. And transparency issues have come to light once again regarding the circumstances around biologics chief Vinay Prasad’s imminent departure and recent request to remain anonymous during a media briefing about uniQure’s gene therapy for Huntington’s disease.

The FDA is dominating the headlines once again thisweek.

Days after FDA Commissioner Marty Makary appeared to question uniQure’s gene therapy candidate for Huntington’s disease, the company revealed that the agency will require it to conduct a randomized, double-blind, sham surgery–controlled Phase 3 study. The FDA also published anothercomplete response letter (CRL), this one for REGENXBIO’s gene therapy for Hunter syndrome. The rejection, sustained by the biotech early last month, was driven by issues with the study’s population, controls and use of surrogate markers to measure efficacy, according to the document.

Meanwhile, regulatory experts have expressed concernsthat the FDA’s circle of trust is shrinking, making many decisions feel like “fiat”—both in terms of individual drug applications and policy. The FDA has reportedly initiated a probe into complaints that a toxic workplace is fostered by CBER director Vinay Prasad, who is at the heart of many of these decisions. Finally, the biopharma industry continues to react to the agency’s pivot from a requirement of two pivotal trials to one for approval, asking why now, what are the risks and what exactly the FDA expects from this one trial. 

Still on the gene therapy front, Sarepta Therapeutics CEO Doug Ingram stepped down last week to spend more time with family as the company’s muscular dystrophy mission hits home. Also during the company’s fourth quarter earnings call, Sarepta projected that sales of its embattled Duchenne muscular dystrophy gene therapy Elevidys will be flat or down as far as 15% in 2026.

On the obesity front, Eli Lilly topped Novo Nordisk again in a weight loss trial, this time in a Lilly-sponsored study of patients with type 2 diabetes. But don’t count Novo out yet. The company is actively seeking out new obesity assets, according to business development executive Tamara Darsow. Just last week, Novo linked with Boston’sVivtex to advance novel weight loss pills.

Finally, check out BioPham Executive this week for a rundown of 2025’s top-selling assets—spoiler: Merck’s Keytruda held onto its crown as number one—and a story on former2seventy exec Chip Baird’s new role as CEO of recently launched Poplar Therapeutics, which secured a $45 million series A extension this week.

The Sarepta saga continued into another week as the FDA recommended that the voluntary hold on the company’s Duchenne muscular dystrophy gene therapy be lifted for ambulatory patients, after determining that the death of an 8-year-old Brazilian Duchenne patient who had received Elevidys’ was not caused by the drug.  Sarepta’s stock has swung wildly and its transparency questioned after it elected not to reveal the death of a third patient—a participant in a trial of a gene therapy for limb girdle muscular dystrophy—during a business update last week.    

Speaking of entities—or individuals—who have trouble staying out of the news, Health Secretary Robert F. Kennedy Jr. plans to dissolve the U.S. Preventive Services Task Force because it is “too woke.” Also on Monday, Kennedy addressed what he called the “broken” vaccine injury compensation program. Without offering details, he vowed to “fix” the U.S.’s VICP and return it to its “original Congressional intent.”  

On the business side of the biopharma house, Q2 earnings are in full swing, with AstraZeneca announcing estimate-beating numbers and CEO Pascal Soriot saying the world “needs to share” in global pharma R&D, while Merck cut $3 billion to support an aggressive launch schedule. Meanwhile, a week ahead of its own earnings report, Novo Nordisk named a new CEO and lowered its 2025 sales guidance for the second time this year.  

In clinical development, the Alzheimer’s Association Annual Conference is underway in Toronto, with Roche’s trontinemab the standout so far. In a Phase Ib/IIa trial, the next-gen anti-amyloid antibody rapidly cleared amyloid from the brains of patients with Alzheimer’s disease after just seven months—besting the 18-month timeframe for Biogen and Eisai’s Leqembi and Eli Lilly’s Kisunla. While Leqembi and Kisunla have shown some progress is slowing down the progression of Alzheimer’s, their effect size is modest and they don’t work for all patients—leaving plenty of room for symptomatic treatments, such as those being developed by Bristol Myers Squibb and Acadia Pharmaceuticals. The space is gearing up for several readouts, for both symptomatic and disease-modifying therapies alike.  

And in BioPharm Executive this week, we dig into the top VC rounds so far this year and highlight a few scrappy biotechs walking the solo road.  

The potential impacts on clinical trial outcomes warrant a discussion surrounding the current definition of women’s health.

In the second episode on our series on women's health, we discuss what may happen to future generations if women, the custodians of generational health, are not comfortable sharing complete medical histories. Additionally, we discuss how broadening the definition will open funding to address women’s health.

Last week, the FDA declined to review Moderna’s mRNA-based flu vaccine, with Center for Biologics Evaluation and Research Director Vinay Prasad himself signing the refuse-to-file (RTF) letter. Prasad said Moderna’s comparator group “does notreflect the best-available standard of care,” while Moderna pushed back, saying CBER had previously found a standard-dose flu shot to be an “acceptable” comparator. Despite the shocking turn of events, HHS backed Prasad, saying Moderna didn’t “follow very clear FDA guidance from 2024.”

Regardless of the reasons, the development imperilsModerna’s breakeven plans, affecting not just the company’s investigational flu vaccine but also a flu-COVID combo shot and other parts of the company’s pipeline. And for the broader industry, it highlights the regulatory uncertainty that persists into 2026, even as other countries move full speed ahead with novel modalities.

That regulatory uncertainty extended this week to DiscMedicine, whose rare disease drug bitopertin was rejectedby the FDA. The company tried to convince investors that its planned Phase 3 trial would pave the way toward a refiling, but analysts raised concerns that the study was developed with oldFDA leadership. Disc’s situation also raises questions about the FDA’s Commissioner’s National Priority Voucher, which bitopertin had received.

Meanwhile, Compass Pathways dropped long-awaited data from two Phase 3 trials of its psilocybin-based COMP360, showing strong durability data that “clearly met the Street’s bar for success,” according to Stifel analysts. The company plans to complete a rolling new drug application by the end of the year.

Finally, the CDC has been left leaderless, again, with the departure of Jim O’Neill, who had been servingas acting director after the ouster of Susan Monarez last summer. And Sanofi’s Paul Hudson was removed as CEO last week. He’ll be replaced by Merck KGaA’s Belén Garijo, who becomes just the second woman in charge of a Big pharmacompany.

A lean funding environment has changed how biotechs approach workforce organization and executive hiring. Searches are becoming more targeted and intentional, and accountability–both for employers and candidates–is high. In this episode of Denatured, Leslie Loveless of Slone Partners describes how biotechs should approach building their executive teams, working with boards and investors to make decisions that will enable growth. She also discusses how the search and hiring processes has changed for both employers and candidates.

This episode is presented in partnership with Slone Partners.
