Extensive data presented on Basilea's anti-infectives isavuconazole, ceftobiprole and BAL30072 at ICAAC
Basel, Switzerland, September 5, 2014 - Basilea Pharmaceutica Ltd. (SIX: BSLN) announces today that extensive data will be presented on the anti-fungal isavuconazole and the antibiotics ceftobiprole and BAL30072 at the 54th Interscience Conference on Antimicrobial Agents and Chemotherapy (ICAAC), September 5-9, 2014 in Washington, DC (USA).
Basilea's Chief Medical Officer Prof. Achim Kaufhold commented: "Basilea looks forward to the presentation at ICAAC of a wealth and breadth of data on its compounds including Zevtera/Mabelio. The significant data presented underscores the promising profiles of our drug and drug candidates in areas of unmet medical need."
Presentations cover the investigational antifungal isavuconazole, which is co-developed with Astellas Pharma Inc. In particular, data from the SECURE isavuconazole invasive aspergillosis phase 3 study with outcome analyses for subsets of patients with hematologic and other malignancies will be presented. Researchers will also present data from the VITAL phase 3 study on the activity of isavuconazole in patients with invasive fungal disease caused by a variety of emerging fungi that are associated with significant morbidity and mortality.
Basilea's isavuconazole Marketing Authorization Application for the treatment of invasive aspergillosis and mucormycosis (zygomycosis) is under regulatory review in Europe, and a New Drug Application has been filed with the U.S. FDA by Astellas.
In addition, post-hoc efficacy and tolerability analyses from two randomized phase 3 studies for certain Asian populations with ceftobiprole, Basilea's broad-spectrum anti-MRSA antibiotic, will be presented.
Ceftobiprole (ceftobiprole medocaril, brand name Zevtera®/Mabelio®) is approved in certain European countries1 for the treatment of hospital-acquired pneumonia (HAP, excluding ventilator-associated pneumonia, VAP) and community-acquired pneumonia (CAP).
Further presentations will include data on the in-vitro activity of Basilea's investigational siderophore monosulfactam antibiotic BAL30072 alone and in combination with carbapenem antibiotics against Gram-negative bacteria, and on the role of siderophore receptors for the susceptibility of Pseudomonas aeruginosa. BAL30072 is currently in phase 1 clinical testing.
Isavuconazole (drug substance: isavuconazonium sulfate) is an investigational once-daily intravenous and oral broad-spectrum antifungal being developed for the treatment of life-threatening invasive fungal infections which predominantly occur in immunocompromised patients such as cancer patients undergoing chemotherapy.
Isavuconazole demonstrated in-vitro and in-vivo coverage of a broad range of yeasts (such as Candida species) and molds (such as Aspergillus species), including emerging and often fatal molds such as those that cause mucormycosis. It has EU and U.S. orphan drug status for the treatment of invasive aspergillosis and mucormycosis. In the U.S., isavuconazole was granted FDA fast-track status and designated a Qualified Infectious Disease Product (QIDP) for invasive aspergillosis, mucormycosis and candidiasis under the U.S. GAIN Act.
In the phase 3 invasive aspergillosis SECURE 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 addition, isavuconazole showed statistically fewer study drug-related adverse events relative to voriconazole. In both treatment groups, the most common treatment-emergent adverse events were nausea, vomiting, pyrexia (fever) and diarrhea.2
Isavuconazole for the treatment of candidiasis is currently being explored in the ongoing phase 3 study ACTIVE, which evaluates the safety and efficacy of intravenously (i.v.) and orally administered isavuconazole versus i.v. caspofungin followed by oral voriconazole in the treatment of invasive Candida infections.
Isavuconazole is being co-developed with Astellas Pharma Inc. Basilea holds full rights to isavuconazole in markets outside of the U.S. and Canada, where Astellas is the exclusive license holder.
Ceftobiprole medocaril (brand names Zevtera®/Mabelio®) is a bactericidal broad-spectrum intravenous antibiotic from the cephalosporin class, covering Gram-positive and Gram-negative pathogens including methicillin-resistant Staphylococcus aureus (MRSA) and Pseudomonas spp., which are frequent causes of hospital-acquired pneumonia.3 It is approved for the treatment of adults with hospital-acquired pneumonia (HAP) (excluding ventilator-associated pneumonia, VAP) and community-acquired pneumonia (CAP) in certain European countries.1
BAL30072 is an investigational intravenous siderophore monosulfactam antibiotic with bactericidal activity against multidrug-resistant Gram-negative pathogens. It is currently investigated in a phase 1 clinical study evaluating the safety, tolerability, and pharmacokinetics of multiple-ascending doses of intravenously administered BAL30072 in combination with meropenem, an antibiotic of the carbapenem class. In-vitro data showed synergistic or additive activity of BAL30072 with antibiotics from this class.4 The phase 1 study is conducted under a contract with the U.S. Biomedical Advanced Research and Development Authority (BARDA), a division within the U.S. Department of Health and Human Services.
