Oct 7 (Reuters) – Biopharma company Halozyme said on Wednesday that a Dutch patent court ruled in its favor against Merck, ordering the drugmaker to halt the manufacture and sale of injectable Keytruda in eight European markets.
Here are some details:
• Halozyme said a specialized Dutch patent court in The Hague found that Merck had infringed one of its patents covering MDASE, Halozyme’s technology for rapid, high-volume under-the-skin drug delivery.
• The court ordered Merck to stop the production and sale of injectable Keytruda in Belgium, Denmark, France, Ireland, Italy, Sweden, Switzerland and the Netherlands.
• The drugmaker has been counting on the simpler-to-use subcutaneous version of the drug, known as Keytruda SC, to help drive growth as key patents on its original intravenous version expire later in the decade.
• Merck did not immediately respond to Reuters’ request for comment.
• “We’re very pleased the Dutch court recognized the validity and infringement of Halozyme’s MDASE patent,” said Mark Snyder, the company’s chief legal officer.
• Halozyme has also sued Merck for patent infringement in the US, alleging the under-the-skin formulation of Keytruda infringes 15 patents that Halozyme has filed since 2011.
• The company sued Merck in Germany and was granted a preliminary injunction last year, stopping Merck’s launch of Keytruda SC in Germany.
