Sep 1, 2026The update gives GSK a new shot at rebuilding a flu vaccine business that shrank by about 25% last year amid competitive pressure in the U.S. It also sharpens the next competitive question in mRNA flu: whether adding neuraminidase to the antigen mix can improve on first-generation products that focus mainly on hemagglutinin.

Sep 1, 2026Takeda’s latest approval adds a second recent launch to what Jefferies described as the company’s next growth cycle.

Aug 29, 2026The stopped study tested whether autogene cevumeran, also known as BNT122, could prevent recurrence after surgery by targeting each patient’s tumor mutations. Instead, Genentech confirmed there were more deaths in the vaccine arm in this patient population, shifting attention to whether the platform’s future depends on combination use rather than standalone treatment.

Aug 29, 2026AstraZeneca and Ionis Pharmaceuticals’ Wainua posted a hazard ratio of 1.14 in ATTR-CM when given alongside standard of care treatment, a result that Stifel called clearly worse than expected. While monotherapy data showed a 29% improvement in cardiovascular events, the combined picture makes a regulatory path harder to see and may influence how rivals position next-generation programs.

Aug 28, 2026BioXcel moved into bankruptcy after warning it lacked funds to operate through the end of August, even after securing a loan earlier this week. Teva’s bid includes $57.5 million upfront and up to $67.5 million in milestones, with the largest payout contingent on BXCL501 winning approval by the current Nov. 14 PDUFA date.

Aug 28, 2026AstraZeneca and Amgen reported that Tezspire significantly improved histologic remission and dysphagia symptoms at 24 weeks in the Phase 3 CROSSING study, with effects sustained through 52 weeks. The announcement matters because Dupixent currently owns the biologic category in eosinophilic esophagitis, yet Tezspire may have a practical differentiator in dosing frequency if the full efficacy data are competitive.

Aug 28, 2026The drug will be sold as Lisraya and taken once daily. For Roivant, the approval turns a rare-disease immunology program into a commercial product in a U.S. market the company says includes between 40,000 and 70,000 people.
