DUBLIN – In what is a truly transformative deal for each company, Gilead Sciences Inc. and Galapagos NV are entering a 10-year research and development alliance under which Galapagos is getting $3.95 billion up front in hard cash plus another $1.1 billion in equity, in return for which Gilead will essentially have an option to ex-European rights on everything emanating from the Belgium firm's clinical and preclinical pipeline. That includes six clinical-stage programs, another 20 in preclinical research and whatever else Galapagos may bring forward – or bring in through its own business development efforts – over the term of the agreement.

Japanese biopharma Carna Biosciences Inc. and Gilead Sciences Inc., of Foster City, Calif., have signed a $470 million R&D collaboration to develop and commercialize small-molecule compounds in immuno-oncology. Under the agreement, Gilead will license worldwide rights to develop and commercialize inhibitors against an undisclosed immuno-oncology target from Kobe, Japan-based Carna. Additionally, Gilead will have access to Carna's lipid kinase drug discovery platform.
