GSK has announced its agreement to acquire IDRx, Inc., a clinical-stage biotech company based in Plymouth, Massachusetts, for an upfront payment of $1 billion. The deal, which could reach a total of $1.15 billion including potential milestone payments of up to $150 million, aims to enhance GSK's portfolio in cancer treatments.

This acquisition aligns with GSK's strategy to address critical patient needs in the oncology space.
