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

Phase 3

Completed

• Conditions: Abscess; Wound Infection; Surgical Site Infection; Cellulitis
• Interventions: Drug: Dalbavancin; Drug: Vancomycin / Linezolid

• Registration Number: NCT01339091
• Lead Sponsor: Durata Therapeutics Inc., an affiliate of Allergan plc

Brief Summary

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.
