Nicox: issuance of a new patent in Japan for the NCX 4251

Posted 22 February, 2022

Nicox SA, an international company specializing in ophthalmology, today announces the issuance by the Japanese Patent Office of a new patent covering Nicox's drug candidate, NCX 4251, in Japan until 2040. The JP patent. 7021301 covers ophthalmic suspensions comprising a specific form of fluticasone propionate nanocrystals as well as the process for manufacturing the ophthalmic suspensions. This patent is in addition to a recently granted European patent of the same family. Patent applications from this same family are pending in the United States, China, and other territories.

"The breadth of protection of our patents and their geographic coverage is very important to the potential future value of the NCX 4251 that we plan to develop in the treatment of dry eye disease. We have strong coverage with patents issued in Europe and Japan; a patent has been filed in the United States. We plan to license the NCX 4251 in Japan in due course. The issuance of this patent extends the period during which we are eligible to potentially receive royalties on sales in Japan," said Gavin Spencer, Chief Business Officer of Nicox.

The NCX 4251 is already covered until 2033 by patents of another family issued in various territories including the United States, Europe, China, and Japan. NCX 4251 is currently in development for the treatment of dry eye disease in the United States.
