TOKYO: Astellas Pharma Inc has bought U.S.-based Xyphos Biosciences Inc to expand its immuno-oncology business, a deal worth up to $665 million including potential development milestones and its second acquisition announced this month.
Japan's second biggest drugmaker by sales paid $120 million upfront for Xyphos and the rest will be milestone payments, the companies said in a statement.
Astellas also said this month it had agreed to purchase Audentes Therapeutics Inc for about $3 billion to expand its push into genetic medicines. The deal is due to close in January.
