Basilea Pharmaceutica International Ltd. has entered into a license,
co-development and co-promotion agreement with Astellas Pharma Inc. (TSE:4503)
for Basilea's azole antifungal agent isavuconazole in phase III clinical
development for the treatment of life-threatening invasive fungal infections on
a worldwide basis, including an option for Japan.

Under the terms of the agreement, Basilea will receive an upfront payment of CHF

Astellas is granted an exclusive right to commercialize isavuconazole whereas
Basilea retains an option to co-promote the product in the United States,
Canada, major European countries and the People's Republic of China. Basilea and
Astellas will jointly participate in the development of isavuconazole. Astellas
will lead the development and contribute the majority of the investments
required for completing the clinical development program investigating
isavuconazole in the treatment of patients with invasive fungal infections
caused byAspergillus or other filamentous fungi (mold infections) and Candida
fungi (yeast infections). Basilea will initially manage manufacturing. Astellas
has the right to take over the management of manufacturing and will bear
manufacturing costs for commercial supply and commercialization costs.

"Astellas has a successful track record in developing and commercializing
antifungals in the hospital sector internationally. We look forward to work
together with Astellas to achieve isavuconazole's full potential as a novel
therapeutic option for treating serious and life-threatening fungal infections.
This partnership further validates the unique and highly competitive profile of
isavuconazole and its potential as a best-in-class antifungal," said Dr. Anthony
Man, CEO Basilea Pharmaceutica Ltd. "The financial contribution from this
partnership allows us to further expand Basilea's commercial efforts in key
markets as needed as well as advance our promising pipeline projects."

"We are excited to be working with Basilea to develop and commercialize
isavuconazole for the treatment of life-threatening invasive fungal infections,"
said Masafumi Nogimori, President and CEO, Astellas Pharma Inc. "Astellas has
already experience in the development and marketing of the echinocandin
antifungal agent Mycamine (micafungin) worldwide and is committed to focus on
infectious diseases. This partnership is an important step to further expand our
business and to reinforce our franchise in infectious diseases."

About isavuconazole

Pre-clinical and clinical data generated to date indicate that isavuconazole has
the potential to overcome many limitations of current therapies for the
treatment of invasive fungal infections. Isavuconazole is given by intravenous
infusion or oral capsules with high oral bioavailability that provides an option
for intravenous-oral step-down. The drug has predictable and dose proportional
pharmacokinetics that are important to ensure adequate therapeutic drug levels
in patients with life-threatening fungal infections. Human studies to-date
suggest the potential for fewer clinical drug-drug interactions. The intravenous
dose form has the potential to be given safely to patients with renal
impairment.
The clinical program includes three international phase III trials with centers
in the U.S., Europe and other regions that target respectively, yeast infections
(candidemia / invasive candida infections), mold infections (invasive
aspergillosis) and finally rare molds and renally impaired patients with
aspergillosis.
Recently, an Independent Data Safety Monitoring Board recommended the
continuation of the phase III clinical trial of isavuconazole for the treatment
of invasiveAspergillus infections based on a futility analysis of the first 180
patients.
Isavuconazole has been granted fast track designation by the U.S. Food and Drug
Administration (FDA).

About invasive fungal infections

Invasive fungal infections are life-threatening. Immunocompromised individuals
like cancer or transplant patients are at special risk of acquiring fungal
infections, mainly caused byCandida and Aspergillus species and associated with
mortality rates between 30% and 90%. It has been shown that early treatment with
highly effective antifungals reduces patient mortality.
