Basel, Switzerland, December 08, 2021

Basilea Pharmaceutica Ltd. (SIX: BSLN), a commercial-stage biopharmaceutical company committed to meeting the needs of patients with infectious diseases and cancer, announced today that sales of the antifungal Cresemba^® (isavuconazole) by its partner Pfizer in Europe, Russia and Israel exceeded the threshold triggering a milestone payment to Basilea of USD 10 million. This is the second sales milestone payment by Pfizer in 2021.

David Veitch, Chief Executive Officer of Basilea, said: “The second 10 million U.S. dollar sales milestone payment by our partner Pfizer, within less than twelve months, confirms that the need for Cresemba continues to increase rapidly. Together with our partners, we at Basilea are determined to make Cresemba available to increasing numbers of patients around the world.”

The license agreement between Basilea and Pfizer covers Europe (excluding the Nordic countries), Russia, Turkey and Israel, as well as China (including Hong Kong and Macao) and sixteen countries in the Asia Pacific region. Basilea is entitled to receive milestone payments upon Pfizer’s cumulative Cresemba sales in Pfizer’s licensed territories exceeding certain thresholds. Pfizer is commercializing Cresemba in most European countries as well as in a number of countries in the Asia Pacific region. Total milestone payments from Pfizer to Basilea amount to USD 38 million to date and Basilea remains eligible for milestone payments of up to approximately USD 610 million, in addition to receiving mid-teen royalties on net sales.

Cresemba has been approved in more than 60 countries to date and is currently marketed in 55 countries, including the United States, most EU member states and additional countries inside and outside of Europe. In the twelve-month period between July 2020 and June 2021, total “in-market” sales of Cresemba amounted to USD 285 million, a 24 percent growth year-on-year.¹
