Dalbavancin (INN, trade name Zeven) is a novel second-generation lipoglycopeptide antibiotic. It belongs to the same class as vancomycin, the most widely used and one of the few treatments available to patients infected with methicillin-resistant Staphylococcus aureus (MRSA).[1]

Dalbavancin (BI397) is a novel semisynthetic lipoglycopeptide that was designed to improve upon the natural glycopeptides currently available, vancomycin and teicoplanin.[2]

It possesses in vitro activity against a variety of Gram-positive pathogens[3][4] including MRSA and MRSE.[5] It is a once-weekly, two-dose antibiotic that Pfizer acquired when it bought Vicuron Pharmaceuticals in 2005.[6]

Clinical progress[edit]

Dalbavancin has undergone a phase III clinical trial for adults with complicated skin infections, but in Dec 2007 the FDA said more data was needed before approval.[6] On September 9, 2008, Pfizer announced that it will withdraw all marketing applications in order to conduct another Phase 3 clinical trial.[7] Durata Therapeutics acquired the rights to dalbavancin in December 2009 and has initiated two new Phase III clinical trials for treatment of acute bacterial skin and skin structure infections.[8] Preliminary results in Dec 2012 looked good.[9]
