Pharmaceutical Executive Daily: September 4, 2025

Welcome to Pharmaceutical Executive Daily, your quick briefing on the top news shaping the pharmaceutical and life sciences industry.

In today’s Pharmaceutical Executive Daily, we cover political pressure on Moderna and Novavax to release COVID-19 vaccine evidence, a deep dive into the evolving GLP-1 market, and Sanofi’s share decline following disappointing Phase III results for Amlitelimab.

Moderna and Novavax are facing heightened political pressure after former President Donald Trump called on both companies to immediately release safety and efficacy data for their COVID-19 vaccines. The companies reaffirmed their commitment to established FDA review processes, stressing that vaccine evidence must be assessed within rigorous regulatory frameworks to safeguard public trust. The pushback reflects broader industry concerns about political influence on scientific oversight, especially as public debate over pandemic-era policies continues.

Meanwhile, GLP-1 medications remain a central focus across the pharmaceutical landscape. A comprehensive analysis highlights both the enormous potential and the significant challenges facing this booming market. With demand for obesity and diabetes treatments continuing to surge, companies must overcome hurdles in manufacturing scale-up, supply chain stability, and payer reimbursement. While leaders like Novo Nordisk and Eli Lilly currently dominate, emerging players are exploring new delivery mechanisms and differentiated formulations that could reshape competition. Analysts expect the GLP-1 category to remain a top investment priority but caution that long-term success will depend on affordability and clinical durability.

And finally, Sanofi shares dropped by 10% after the company announced topline results from its Phase III trial. The therapy underwent study for inflammatory skin conditions, and failed to meet key endpoints, disappointing investors and raising questions about Sanofi’s late-stage pipeline strength. While the company maintains a diverse R&D portfolio, the setback underscores the risks in high-profile development programs.
