• Beyond the Gluten-Free Diet: A New Era in Celiac Disease Treatment

  In this episode presented by AnaptysBio, Jennifer Smith-Parker speaks to Dr. Joe Murray, professor of medicine, Division of Gastroenterology and Hepatology, Department of Internal Medicine, and Department of Immunology, The Mayo Clinic; Marilyn Gellar, CEO, The Celiac Disease Foundation; and Dr. Paul Lizzul, chief medical officer, AnaptysBio, about the unmet need for effective treatments for celiac disease, the limitations of the gluten-free diet and the development of ANB033, a first-in-class CD122 antagonist designed to modulate IL-2/IL-15 signaling.HostJennifer Smith-Parker, Director of Insights, BioSpaceGuestsDr. Joe Murray, Professor of Medicine, Division of Gastroenterology and Hepatology, Department of Internal Medicine and Department of Immunology, The Mayo ClinicMarilyn Geller, CEO, Celiac Disease FoundationDr. Paul Lizzul, Chief Medical Officer, AnaptysBio Disclaimer: The views expressed in this discussion by guests are their own and do not represent those of their organizations.

• Weight Loss Waves, Pazdur’s Exit and FDA Instability, New Neuro Breakthroughs

  Pfizer followed up its winning $10 billion bid forobesity startup Metsera by adding another molecule to its obesity cabinet, thisone from Chinese firm YaoPharma in a deal worth up to $1.9 billion licensing deal announced Tuesday. Meanwhile, Wave Life Sciences and Structure Therapeutics may have changed the weight loss landscape with early and mid-stagedata from their candidates that analysts called “very disruptive” and “highlycompetitive,” respectively.  At the FDA, the confusion and instability continuewith the retirement of agency veteran Richard Pazdur just three weeks into hisrole as CDER director. Pazdur’s exit leaves the FDA with just three veteran leaders from one year ago. The CDC similarly made headlines last week as therevamped vaccines advisory committee voted to recommend postponing the hepatitis B vaccination from birth to two months of age for some infants. Meanwhile, the Clinical Trials on Alzheimer’s Disease (CTAD)conference generated excitement in the space as Roche, Eisai and others presentednew data from their respective candidates. The star of the show was Roche’snext-gen antibody trontinemab, which lowered amyloid levels below the threshold of positivity in 92%of treated patients in a mid-stage study. Meanwhile, Eisai isdetermined to buck the losing the trend in the anti-tau space. The company’s etalanetugreduced all measurable forms of MTBR-tau243—a specific biomarker of tau tanglepathology in Alzheimer’s—in a Phase Ib/II trial, according to an oralpresentation at CTAD.  Finally, check outthis week’s deep dives in BioPharm Executive on what pharmas are learning fromthe Chinese biotech sector and how Japan’s pharma industry is setting itssights on the global market.

• New Approach Methodologies: Redefining Animal Testing Alternatives

  Momentum is building behind New Approach Methodologies (NAMs) that offer stronger human relevance than traditional animal testing. The FDA issued on December 2 a draft guidance outlining specific product types for which the agency believes six-month non-human primate toxicity testing can be eliminated or reduced.  The guidance followed a proposed agency template for NAMs in April. There is also an initiative called the Validation and Qualification Network, with dozens of partners from regulators, like the FDA and European Commission, to Big Pharmas and CROs, such as Sanofi, Novo Nordisk, GSK and Charles River Laboratories, that had a July meeting. In addition, Reuters reported in September that AI-driven drug discovery picks up as FDA pushes to reduce animal testing.In this episode of Denatured, Jennifer C. Smith-Parker speaks to Stacey Adam, PhD, Vice President of Science Partnerships at the Foundation for the National Institutes of Health and Patrick Smith, Senior Vice President, Translational Science at Certara, to discuss the latest regulatory news and the future for NAMs development.HostJennifer Smith-Parker, Director of Insights, BioSpaceGuestsPatrick Smith, Senior Vice President, Translational Science, CertaraStacey Adam, PhD, Vice President of Science Partnerships, Foundation for the National Institutes of HealthDisclaimer: The views expressed in this discussion by guests are their own and do not represent those of their organizations.

• Prasad’s Leaked FDA Memo, Alzheimer’s Ups and Downs, Next-Gen Obesity Drugs

  Vinay Prasad’s memo, leaked over the weekend, has sent vaccine makers’ stocks slipping and experts clamoring for more evidence to support the CBER director’s claim that COVID vaccines have led to the deaths of at least 10 children. It’s the latest insult to the vaccine sector from the healthcare administration this year, with other challenges coming on the CDC side, where the recently revamped advisory committee is heading into its next meeting with a brand new chair.  Elsewhere at the FDA, newly promoted Center for Drug Evaluation and Research Director Richard Pazdur has filed the paperwork to retire from the agency just weeks after reportedly reluctantly accepting the position.   Meanwhile, the Alzheimer’s space is buzzing as the 2025 Clinical Trials on Alzheimer’s Disease (CTAD) conference continues in San Diego. Last week saw a mid-stage flop for Johnson & Johnson’s anti-tau candidate and the “definitive” failure of Novo’s GLP-1 semaglutide—which analysts say may actually help uptake of anti-amyloid therapies from Biogen and Eli Lilly. Meanwhile, Roche announced positive results for its latest antibody, putting the pharma back in the game it had once stepped back from in the tumultuous days of Aduhelm.   In the weight loss space, Novo Nordisk revealed ‘competitive’ mid-stage data for its next-gen amycretin, which showed no weight-loss plateau over 36 weeks in patients with type 2 diabetes. Meanwhile, the pricing war for approved and future GLP-1s from Novo and obesity rival Eli Lilly rages on, with Lilly this week announcing another price drop for Zepbound through its LillyDirect self-pay platform.  In BioPharm Executive this week, we review the top venture capital rounds for female-founded biotechs and examine the 2026 biotech market outlook.

• Billions More in M&A, Another Bidding War and More FDA Drama

  Acquisitions have ticked up this month as all eyes were on Pfizer and Novo’s fight over Metsera. The past week saw that deal finalized with Pfizer as the winner plus a handful of other M&A stories, including Merck’s $9.2 billion buyout of Cidara Therapeutics and Johnson & Johnson’s $3 billion bet on Halda Therapeutics. Additionally, a separate bidding war has broken out between Lundbeck and Alkermes for sleep biotech Avadel Pharmaceuticals. Outside of M&A, the FDA dominated headlines again this week. The agency effectively closed the loop on one of the messiest stories of the year—Sarepta’s gene therapy Elevidys—when it formally added a black box warning for serious liver toxicities and risk of death and removed the nonambulatory indication from the label. The agency will also require that the company complete a postmarketing observational study of around 200 patients. This happened just as Richard Pazdur accepted the role of director of the Center for Drug Evaluation and Research (CDER) that was recently vacated by George Tidmarsh amidst conflict with Center for Biologics Evaluation and Research (CBER) Director Vinay Prasad. By all accounts, Pazdur, a 26-year FDA veteran, is a highly respected and thoughtful regulator, and sources told BioSpace that if Prasad tries to supersede Pazdur’s authority, “there will be hell to pay and resignations to be handed in.” In other FDA drama, FDA Commissioner Marty Makary is apparently butting heads with Health Secretary Robert F. Kennedy Jr. Meanwhile, the agency revealed details of its plausible mechanisms pathway teased by Makary earlier in his tenure. Finally, in Biopharm Executive this week, check out our deep dives into GLP-1 pricing. Coming off Trump’s deal with both Eli Lilly and Novo Nordisk to offer their GLP-1s at a lower cost through the president’s new direct-to-consumer platform, Novo CEO Maziar Mike Doustdar announced a sale on its company’s products. Bargain bin pricing like this so early in a drug’s market life is unprecedented. It’s changing the investment calculations for the next-generation of obesity treatments.
