The transaction is valued at up to $2.175 billion, which includes an upfront cash payment of $1.675 billion and potential milestone payments of up to $500 million.
This acquisition adds OM336, a promising clinical-stage T cell engager, to Gilead's inflammation portfolio. The therapy targets severe autoimmune diseases and has received Fast Track designation. Gilead will also partner with Galapagos, which will co-fund the deal, manage development costs through initial studies, and in return receive sales royalties between 20% and 23%.
