Basilea Pharmaceutica Ltd (SIX: BSLN), a commercial-stage biopharmaceutical company committed to meeting the needs of patients with severe bacterial and fungal infections, announced today that its license partner Asahi Kasei Pharma (“AKP”), has received the marketing authorization from the Ministry of Health, Labour and Welfare (MHLW) in Japan for Cresemba® (isavuconazole) for the treatment of adult patients with aspergillosis, mucormycosis, and cryptococcosis. Aspergillosis and cryptococcosis were recently listed by the World Health Organization as most critical fungal infections that pose a major health risk.1

David Veitch, Basilea’s CEO, stated: “We congratulate our partner AKP on the approval of Cresemba in Japan, which is an important commercial market for newer antifungals. We look forward to continue working together with AKP to make Cresemba available to patients for whom invasive fungal infections can pose a serious threat.”

Cresemba is approved in 69 countries to date and is currently marketed in 59 countries, including the United States, China, most EU member states and additional countries inside and outside of Europe. In the twelve months between July 2021 and June 2022, total global in-market sales of Cresemba amounted to USD 352 million, a 24 percent growth year-on-year.2
