Bacteremia, Endocarditis
Conditions
Brief summary
This study will compare dalbavancin to standard of care (SOC) antibiotic therapy for the completion of therapy in patients with complicated bacteremia or infective endocarditis.
Interventions
Dalbavancin 1500 mg, intravenous (IV) administration over 30 minutes on Day 1, and on Day 8.
Antibiotic consistent with Standard of Care (SOC), based on baseline pathogen, for 4 to 6 weeks.
