GSK Plc is to acquire the US oncology developer Nuvalent Inc for $10.6 billion, giving it two late-stage products for non-small cell lung cancer to complement its own Phase 3 antibody-drug conjugate (ADC) for a different lung cancer. The deal, which will be financed with new and existing debt facilities, also gives the UK company a third lung cancer drug in Phase 1 and a preclinical portfolio of undisclosed cancer assets.
