Seeking to accelerate the company's long-term growth through an expansion of its rare disease pipeline, Horizon Therapeutics plc said Feb. 1 it will buy Viela Bio Inc. for $3.05 billion, or $53 per share (NASDAQ:VIE). Once closed, the deal would add a new commercial-stage asset, Uplizna (inebilizumab), to Horizon's portfolio alongside its current lead products, Tepezza (teprotumumab) for the treatment of thyroid eye disease and Krystexxa (pegloticase) for uncontrolled gout. Dublin-based Horizon, which had $2.08 billion in cash at the end of 2020, borrowed $1.3 billion to help finance the transaction. Astrazeneca plc also enabled the deal by agreeing to divest its 26.7% share in Viela Bio for a profit of between $760 million and $780 million.
