  • Background:

    Dalbavancin is a lipoglycopeptide antibiotic with activity against Gram-positive pathogens and a long half-life allowing for intermittent weekly dosing.  Over the last ten years, nine phase two or three clinical trials have been performed for treatment of skin or catheter associated infections. 


    We analyzed the safety data obtained from all phase 2 and phase 3 clinical trials of dalbavancin.

    Treatment related adverse events occurring at >1% on either dalbavancin or the comparator included nausea (2.8% vs. 3.3%), diarrhea (2.5% vs. 3.7%), headache (1.5% vs. 1.6%), elevated gamma-glutamyl transferase (1.1% vs. 1.0%), rash (1.0% vs. 1.1%), vomiting (1.0% vs. 0.9%) and pruritus (0.6%vs 1.9%). The median duration of an adverse event on dalbavancin was 3.0 days vs. 4.0 days on the comparator.


    Dalbavancin was well tolerated in patients enrolled in the phase 2/3 clinical program with fewer overall treatment related adverse events and a duration of any adverse event, on average, no longer than that of the comparator.
