(Reuters) -Pfizer ( PFE ) won a $10 billion bidding war for Metsera ( MTSR ), beating Danish rival Novo Nordisk, securing access to the U.S. biotech's experimental obesity drug assets.

The move adds to a growing list of high-profile transactions over the past decade by U.S. pharmaceutical companies to acquire promising therapies in fields ranging from oncology, neurology to rare diseases and obesity.

Globally, $105.3 billion worth of pharmaceuticals and biotech M&A deals have been signed as of July 9 this year, according to data compiled by LSEG, up 7% from year-ago levels and the highest year-to-date total since 2023.
