Astellas to Showcase Isavuconazole Data at ICAAC

NORTHBROOK, Ill., Sept. 5, 2014 /PRNewswire/ -- Astellas announces today the data that will be presented on the anti-fungal isavuconazole at the 4^th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC), September 5-9 in Washington, D.C.

The Presentations at ICAAC will feature data from the SECURE isavuconazole invasive aspergillosis Phase 3 study with outcome analyses for subsets of patients with hematologic and other malignancies. Astellas is presenting pharmacokinetic and pharmacodynamics data as well as clinical data in patients with other fungal infections, including fusarium and scedosporium, Cryptococcus and dimorphic fungal diseases.

Astellas has submitted a New Drug Application (NDA) to the U.S. Food and Drug Administration (FDA) for isavuconazole for the treatment of invasive aspergillosis and invasive mucormycosis (also known as zygomycosis), which are life-threatening fungal infections predominantly occurring in immunocompromised patients.

The FDA designated isavuconazole as a Qualified Infectious Disease Product (QIDP) for both invasive mucormycosis and invasive aspergillosis. QIDP status provides priority review and a five-year extension of market exclusivity in the United States. QIDP incentives were granted under the 2012 U.S. Generating Antibiotic Incentives Now (GAIN) Act as a part of the FDA Safety and Innovation Act. Also, in 2013, isavuconazole was granted Orphan Drug status for invasive aspergillosis and invasive mucormycosis which, if approved, will result in the product having seven years of market exclusivity in addition to that provided under the GAIN Act.

About Isavuconazole

Isavuconazole (drug substance: isavuconazonium sulfate) is an investigational once-daily intravenous and oral broad-spectrum antifungal being developed for the treatment of severe invasive and life-threatening fungal infections. Isavuconazole is the active moiety of the prodrug isavuconazonium sulfate. Information regarding isavuconazole ongoing clinical trials is available at clinicaltrials.gov.  

Isavuconazole demonstrated in-vitro and in-vivo coverage of a broad range of yeasts (such as Candida species) and molds (such as Aspergillus species) as well as activity against emerging and often fatal molds including those that cause mucormycosis.

In the Phase 3 invasive aspergillosis study, isavuconazole demonstrated non-inferiority to voriconazole on the primary endpoint of all-cause mortality at day 42.  The treatment-emergent adverse events for isavuconazole were statistically fewer relative to voriconazole in the System Organ Classes of hepatobiliary, skin and eye disorders. In both treatment groups, the most common treatment emergent adverse events were nausea, vomiting, pyrexia (fever) and diarrhea.

Isavuconazole is being co-developed with Basilea Pharmaceutica International Ltd.
