Overview
Pfizer’s push into long-acting obesity treatments is getting its first real readout since the company’s $10B Metsera deal. Two reports highlight the same Phase 2/2b dataset from different angles: one emphasizes that the monthly GLP-1 approach showed continued weight loss after patients switched to monthly dosing, while another notes an analyst view that the results look slightly behind Lilly’s market-leading Zepbound—setting up an early benchmark for how competitive Pfizer’s long-acting strategy may be.
