Pfizer Inc is reportedly holding talks to acquire Seagen Inc, the developer of antibody-drug conjugates (ADC), according to a report in The Wall Street Journal on 26 February. This comes several months after Seagen was courted by Merck & Co Inc, but these negotiations failed to conclude. The discussions with Merck reportedly centered on a deal worth $40 billion or more. Seagen currently has a market value of about $30 billion and would be expected to seek a premium over that price, the newspaper said.
