About isavuconazole

Isavuconazole is a novel intravenous and oral broad-spectrum antifungal. In collaboration with Astellas Pharma Inc., isavuconazole is being investigated in a phase III program for the treatment of severe invasive and life-threatening fungal infections. The drug demonstrated excellent 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 less prevalent but often fatal molds such as Zygomycetes spp. It has reliable and predictable dosing, allowing a switch from IV administration to a convenient once daily oral dose and has the potential to overcome many of the limitations of current treatment options.

About ceftobiprole

Ceftobiprole is a novel broad-spectrum antibiotic for the potential treatment of severe, multidrug-resistant bacterial infections. The drug has activity against a wide range of Gram-positive bacteria, including the MRSA ‘superbug’ and clinically relevant Gram-negative bacteria. Ceftobiprole has met the study endpoints in several phase III trials and has shown a typical cephalosporin safety profile. A Marketing Authorization Application has been submitted in Europe through the decentralized procedure.

About BAL30072

BAL30072 is a novel investigational bactericidal sulfactam antibiotic in phase I, specifically targeting multidrug-resistant Gram-negative bacteria. The innovative antibacterial drug has demonstrated broad in-vitro and in-vivo coverage of Gram-negative pathogens including multidrug-resistant Pseudomonas aeruginosa and Acinetobacter baumannii. It has robust activity against common strains of bacteria that produce antibiotic-inactivating enzymes including extended-spectrum beta-lactamases (ESBL) and metallo-beta-lactamases such as the New Delhi metallo-beta-lactamase 1 (NDM-1). In addition, BAL30072 has been shown to enhance the activity of antibiotics from the penem class.
