Pharmaceutical company Amgen has agreed to pay about $28 billion to buy Horizon Therapeutics, which has its U.S. headquarters in Deerfield.
Horizon, which is based in Ireland, sells orphan drugs, which are medications for rare diseases, and drugs to treat rheumatic diseases. As of 2020, it had about 1,200 employees.

The news Monday came just a couple of weeks after Horizon confirmed it was in discussions with Amgen, Janssen Global Services and Sanofi over a possible acquisition.
A spokesman did not immediately respond to a question Monday about the future of Horizon’s Deerfield office.
More to come.
