(Adds details from regulatory filing in paragraphs 2 & 5;
background in paragraphs 3 & 4)
July 14 (Reuters) - The US Federal Trade Commission
(FTC) has sought additional information and documentary material
related to Pfizer's PFE.N proposed acquisition of Seagen Inc
SGEN.O , Seagen said on Friday.
The antitrust agency sent the requests separately to both
the companies, a regulatory filing said.
Pfizer struck a $43 billion deal in March to acquire
Seagen and its targeted cancer therapies, to counter the fall in
COVID-related sales and generic competition for some top-selling
drugs.
The recent scrutiny by the antitrust agency to block
Amgen's AMGN.O $27.8 billion deal to buy Horizon Therapeutics
HZNP.O has made investors jittery around the Pfizer-Seagen
deal as well.
Seagan continues to expect its merger with Pfizer will be
completed in late 2023 or early 2024, it said in the filing.
