ENTA--
The stock's rise came amidst a patent infringement lawsuit filed by Enanta Pharmaceuticals in the European Union's Unified Patent Court. Enanta alleges that Pfizer's COVID-19 treatment, Paxlovid, infringes on its European Patent No. EP 4 051 265. This lawsuit follows a dismissed U.S. case that Enanta plans to appeal. The potential impact on Paxlovid's revenue stream remains significant, although Pfizer maintains confidence in its intellectual property [1].
Adding to the challenges, Pfizer reported a Phase III trial failure for a sickle cell disease candidate acquired in 2022. This drug was a key growth hope for the company's oncology division. Despite strong Q2 2025 results driven by 71% growth in Paxlovid sales and 95% higher Comirnaty vaccine revenue, these setbacks highlight risks in Pfizer's R&D pipeline [1].
Analysts warn that the dual challenges may weigh on investor sentiment, but the stock's modest rise suggests market confidence in its broader portfolio and capital allocation strategy [1].
