HALO Wins Court Order Blocking Merck's Keytruda SC in Europe
A Dutch patent court ruled that Merck's Keytruda subcutaneous formulation infringes Halozyme's MDASE patent, ordering Merck to cease manufacturing and sales across eight European markets. The ruling does not affect Keytruda's intravenous version. This marks another legal victory for Halozyme against Merck, though the company clarified that its separate ENHANZE technology and licensing business remain unaffected.
