The assets that we have acquired complement our existing portfolio and could lead to new medicines and combinations addressing a broad range of treatment and prevention needs of people living with HIV."

Under the terms of the transactions, ViiV Healthcare acquired late-stage HIV R&D assets from Bristol-Myers Squibb for an initial upfront payment of $317 million followed by development and first commercial sale milestones of up to $518M, and tiered royalties on sales.
