    Autoimmune CAR-T: Navigating the FDA’s new regulatory playbook

    For more than a decade, CAR-T therapy has been the miracle of oncology, turning end-stage blood cancers into curable diseases. But the application of these engineered cell therapies is expanding to reset the immune system for patients living with lupus, stiff person syndrome and other autoimmune conditions. And with new frontiers come new rules. In this week’s episode of "The Top Line," Fierce Pharma’s Angus Liu chats with Harpreet Singh, M.D., chief medical officer at Precision for Medicine and a former director of the FDA's Division of Oncology, about a recent article by FDA officials led by CBER Director Vinay Prasad, M.D., laying out the agency’s perspective on its regulation of autoimmune CAR-T therapies. Singh discusses how the agency’s "case-by-case" approach, as indicated in the article, could be similar to—and different from—CAR-T for oncology indications. She also talks about how drug developers should follow existing development experience, as well as prepare for specific requirements for long-term patient follow-up and potential new clinical endpoints from the agency.

    Trump's tariff threats, measured by manufacturing

    Though uncertainty still surrounds the Trump administration’s pharmaceutical import tariffs, the trade rhetoric set off a clear response across the industry in 2025. Drugmakers accelerated U.S. manufacturing plans, pushing production higher as companies looked to insulate their supply chains. Now, with many of those moves already underway, that breakneck pace is expected to level off through 2026 and 2027, according to a recent outlook from Atradius. In this week’s episode of "The Top Line," Fierce Pharma’s Fraiser Kansteiner speaks with Brady McKinney, an underwriter for Atradius' pharmaceuticals sector focusing on the Americas, about the credit insurer's recent industry report. McKinney explains how tariff concerns drove last year’s manufacturing surge and why Atradius expects a period of stabilization ahead. He also discusses how companies are weighing the risk of future trade flare-ups and what that could mean for production, investment and credit conditions across the sector.
