LONDON – Sosei Heptares has added Genentech Inc. to the list of partners seeking access to its G protein-coupled receptor (GPCR) expertise, signing a collaboration with a headline value of $1 billion with the Roche Group company.

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.
