Protocol Description
Dalbavancin as an Option for Treatment of S. Aureus Bacteremia (DOTS): A Phase 2b, Multicenter, Randomized, Open-Label, Assessor-Blinded Superiority Study to Compare the Efficacy and Safety of Dalbavancin to Standard of Care Antibiotic Therapy for the Completion of Treatment of Patients With Complicated S. Aureus Bacteremia
This is a double-blind, multicenter, prospective, randomized, assessor-blinded superiority study. The study will compare dalbavancin to standard of care antibiotic therapy for the completion of therapy in patients with complicated bacteremia or right-sided native valve Infective Endocarditis (IE) caused by S. aureus who have cleared their baseline bacteremia. Approximately 200 subjects will be randomized 1:1 to receive either dalbavancin or a standard of care antibiotic regimen that is based upon the identification and antibiotic susceptibility pattern of the baseline organism. Subjects randomized to the dalbavancin treatment group will receive 2 doses of dalbavancin intravenously (IV) 1 week apart (1500 mg on Day 1 and Day 8 after randomization, with renal dose adjustment if appropriate). Subjects randomized to the standard of care antibiotic therapy treatment group will receive an antibiotic regimen considered to be standard of care based on the methicillin susceptibility pattern of the pathogen isolated at baseline for a duration of 4 to 6 weeks and up to 8 weeks for patients with vertebral osteomyelitis/discitis.
