Good morning from Pharma Daily: the podcast that brings you the most important developments in the pharmaceutical and biotech world. Today, we delve into a series of insightful updates that highlight the dynamic and rapidly evolving nature of these sectors, driven by scientific advancements, regulatory shifts, and strategic industry maneuvers.Starting with Merck, which is strategically planning for a post-Keytruda era, projecting over $70 billion in annual opportunities over the next decade. With Keytruda's patent expiration looming in 2028, Merck is actively expanding its portfolio through acquisitions and partnerships, focusing on oncology and immunology. These areas have been significantly impacted by Keytruda's success, and Merck's proactive approach aims to sustain growth and innovation beyond its current flagship product. During their 2025 full-year earnings call, CEO Robert Davis emphasized their expansive pipeline, highlighting recent strategic deals as pivotal to Merck's robust pipeline—the broadest it has been in years—signaling long-term growth through diversified therapeutic areas and innovative drug candidates.The U.S. Food and Drug Administration (FDA) is making waves with its regulatory approach to CAR-T cell therapies for autoimmune diseases. This shift reflects an increasing recognition of the potential these therapies hold for transforming treatment paradigms for conditions like lupus and multiple sclerosis. By offering a more flexible regulatory framework, the FDA is encouraging innovation while maintaining a focus on patient safety.In other regulatory news, AstraZeneca faces a setback with the FDA's rejection of its subcutaneous version of Saphnelo for lupus. The decision underscores the challenges associated with developing more patient-friendly administration methods for biologics. However, AstraZeneca remains optimistic about achieving a quick turnaround in the approval process, which could enhance patient adherence by offering a self-administered alternative to intravenous infusions.Sanofi finds itself in the spotlight after CEO Paul Hudson was sanctioned by the UK's Prescription Medicines Code of Practice Authority for making overly ambitious claims about Pfizer's RSV vaccine. This incident illustrates the competitive nature of vaccine procurement and underscores the importance of accurate communication by pharmaceutical leaders.In Massachusetts, Thermo Fisher Scientific is reducing its workforce with the closure of its Franklin site, impacting around 200 employees. This move is part of broader strategic realignments within the industry aimed at optimizing operations and focusing resources on high-growth areas.Acadia Pharmaceuticals faces potential rejection by the European Union for its drug trofinetide intended for Rett syndrome. This highlights ongoing challenges in gaining approval for treatments targeting rare diseases, despite their significant unmet needs.Meanwhile, GSK plans to lay off up to 350 R&D workers across the U.S. and UK as part of efforts to streamline operations and focus on core therapeutic areas. Such layoffs reflect broader industry trends toward consolidation and efficiency amid rising R&D costs.On a more promising note, Pfizer's GLP-1 receptor agonist has demonstrated significant results in a Phase 2b trial for weight loss, validating their substantial investment in this area. The drug's potential to offer competitive weight loss results with monthly dosing positions it as a strong contender in the obesity treatment market. Additionally, Pfizer continues to accelerate its efforts in obesity treatment with promising mid-stage trial results for PF-3944, showing up to a 12.3% weight loss at 28 weeks. This suggests Pfizer is keen on expanding its presence in obesity management through strategic clinical development as competition within this therapeutic area intensifies.The U.S. Department of Health and HumanSupport the show
