Pfizer Inc. (PFE) finally topped Novo Nordisk (NVO) to buy Metsera after Novo raised its bid twice. Metsera’s crown jewel is MET-097i, a weekly and monthly injectable GLP-1 asset that’s about to begin Phase III development, writes John McCamant, editor of Medical Technology Stock Letter. Pfizer ended up paying $10 billion, a significant uptick from the $5 billion value of the companies’ original buyout deal, inked in September.
