WASHINGTON, May 16 (Reuters) - The U.S. Federal Trade
Commission said on Tuesday that it would sue to stop Amgen Inc's
AMGN.O $27.8 billion deal to buy Horizon Therapeutics Plc
HZNP.O .
The deal, which was announced in December 2022, would give
Amgen two fast-growing drugs, the thyroid eye disease treatment
Tepezza and gout treatment Krystexxa. Amgen hopes they can act
as a bulwark against competition for its blockbuster arthritis
drug Enbrel.
Furthermore, other key drugs in its portfolio, such as
psoriasis therapy Otezla, face loss of patents over the next few
years.
