Basilea Pharmaceutica Ltd. (CH) - Basilea presents new efficacy data on BAL30072, its novel antibiotic against Gram-negative bacteria
Basel, Switzerland, May 18, 2009 - Data on Basilea Pharmaceutica Ltd.'s compounds including new results on its novel antibiotic BAL30072 presented at the European Congress of Clinical Microbiology and Infectious Disease (ECCMID). The data on BAL30072 provide further evidence for its potent bactericidal activity in vitro against a broad range of clinical isolates of difficult-to-treat, multi-resistant Gram-negative bacteria.
Multi-resistant Gram-negative bacteria are appearing with increasing frequency in hospitals around the world and are causing a growing therapeutic problem. Infections caused by multi-resistant bacilli have been associated with prolonged hospital stays, higher healthcare costs and increased mortality, particularly when initial antibiotic therapy does not provide coverage of the causative pathogen.
A potent single agent New research data presented at ECCMID by Bowker and co-authors confirm that BAL30072, as a single agent, has broad-spectrum in-vitro activity against many of the most difficult-to-treat, multi-resistant Gram-negative "superbugs", including common species of enteric bacteria, thus closing the activity gaps of currently available Gram-negative agents (Poster P1112).
Synergistic effects with carbapenems BAL30072 has been shown to have strong bactericidal activity in vitro against multi-resistant Gram-negative bacteria, including carbapenem-resistant strains. New in-vitro data presented at ECCMID show that the already low rate of resistance development to BAL30072 in difficult-to-treat bacilli such as P. aeruginosa and Acinetobacter spp. is further decreased when BAL30072 is combined with currently marketed Gram-negative antibiotics such as carbapenems. Concomitantly its bactericidal activity is increased in such a combination (P1110, P1111).
BAL30072's unrivaled in-vitro properties suggest that it has the potential to become a unique, novel treatment option for severe hospital infections caused by multi-resistant Gram-negative bacteria.

BAL30072 - a trojan horse fighting resistance BAL30072 is a novel siderophore monobactam that exploits the natural nutrient uptake like a trojan horse. Its unique pattern of penicillin-binding-protein inhibition and its bactericidal mode of action confer potent in vitro activity against Gram-negative fermentors and non-fermentors. These properties enable BAL30072 to overcome most of the genetically defined factors of beta-lactam resistance. In addition to the potent inhibition of Pseudomonas, Acinetobacter spp. and Enterobacter spp. BAL30072 also exhibits strong activity against Burkholderia spp. and Stenotrophomonas, two of the more difficult to treat Gram-negative pathogens.
