Celltrion announced last week that it has filed for marketing approval of Herzuma (trastuzumab) with Japan’s Ministry of Health, Labor and Welfare. Herzuma is indicated for the treatment of breast and gastric cancers. This would be Celltrion’s second biosimilar to be licensed in Japan, after RemsimaTM (infliximab), and according to The Korea Herald, Herzuma will be distributed exclusively by Nippon Kayayu in 2018.
