"Merck's $680M Acquisition of Harpoon Therapeutics Sends Stock Soaring 111%"
Merck & Co announces its acquisition of cancer drug developer Harpoon Therapeutics for $680 million, aiming to strengthen its oncology portfolio with immunotherapies as it prepares for potential competition for its blockbuster drug Keytruda. The deal offers a 118% premium to Harpoon's last stock close, causing its shares to more than double. Harpoon is known for its early-stage development of two immunotherapies for lung cancer and multiple myeloma, which harness the body's immune system to combat cancer.
