Efficacy and Safety of Dalbavancin for the Treatment of Acute Bacterial Skin and Skin Structure Infections

A Phase 3, Randomized, Double-Blind, Double-Dummy Study to Compare the Efficacy and Safety of Dalbavancin to a Comparator Regiment (Vancomycin and Linezolid) for the Treatment of Acute Bacterial Skin and Skin Structure Infections

The primary object is to compare the early clinical efficacy (after 48-72 hours of therapy) of dalbavancin to the comparator regimen (vancomycin with the option to switch to oral linezolid) for the treatment of patients with a suspected or proven gram-positive bacterial skin or skin structure infection.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
