Dalbavancin is a lipoglycopeptide antibiotic recently approved by the United
States Food and Drug Administration (FDA) for acute bacterial skin and skin
structure infections (ABSSSIs). It is active against gram-positive pathogens,
including methicillin-resistant Staphylococcus aureus (MRSA), and minimum
inhibitory concentrations (MICs) are consistently <0.125 µg/ml, much lower than
most other anti-MRSA agents. Dalbavancin possesses an extended half-life of over
1 week, allowing an initial dose of 1000 mg followed by 500 mg 1 week later to
complete a course of therapy for ABSSSI. It is approximately 95% protein bound
and is widely distributed throughout the body, achieving concentrations similar
to plasma levels in numerous tissues. Against MRSA, dalbavancin is 4-8 times more
potent than vancomycin in vitro, and limited data suggest it possesses activity
against MRSA with reduced susceptibility to vancomycin such as hVISA and VISA.
Dalbavancin also possesses in vitro activity against streptococci and
enterococci, although activity against vancomycin-resistant enterococci is
lacking. In phase 3 ABSSSI studies, dalbavancin demonstrated similar activity to
vancomycin and provides a more convenient dosing regimen. Limited phase 2 data
suggest dalbavancin also possesses activity in catheter-related bloodstream
infections. Potential further therapeutic uses include conditions that require
long-term treatment such as osteomyelitis and infective endocarditis, although
data are currently lacking. The extended half-life of dalbavancin, along with its
in vitro activity against gram-positive organisms with reduced susceptibility to
other anti-MRSA antibiotics, suggest it could have an exciting clinical role
going forward.
