San Francisco, CA (UroToday.com) -- Photocure ASA is pleased to announce that the United States Patent and Trademark Office (USPTO) has granted US Patent No. 10,556,010 covering the use of Blue Light Cystoscopy (BLC®) with Hexvix as neoadjuvant* therapy in the treatment of bladder cancer in patients who are scheduled for a cystectomy.

Photocure has the intention to further investigate Hexvix for its therapeutic effect and the patent is a result of Photocure’s continued focus on securing intellectual property rights for its research results and pipeline activities.
The patent was issued on 11 February 2020 and will expire in December 2036.
