Summary

This is a Phase 2b clinical study, multicenter, randomized, open-label, 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. The primary objective is to compare the Desirability of Outcome Ranking (DOOR) at Day 70 of dalbavancin to that of standard of care antibiotic therapy used to consolidate therapy for the treatment of subjects with complicated S. aureus bacteremia in the intent-to-treat population (ITT).

Conditions

  • Staphylococcal Bacteraemia

Interventions

DRUG

Cefazolin

Cefazolin is a semisynthetic cephalosporin analog with broad-spectrum antibiotic action due to inhibition of bacterial cell wall synthesis. Cefazolin (2 g will be administrated intravenously (IV) every 8 hours for 4-6 weeks)

DRUG

Dalbavancin

A second-generation lipoglycopeptide antibiotic synthesized from a fermentation product of Nonomuraea species

DRUG

Daptomycin

Daptomycin (USA) or Cubicin (Spain) is a cyclic lipopeptide antibiotic that inhibits gram-positive bacteria. Daptomycin (6-10 mg/kg will be administrated intravenously (IV) daily for 4-6 weeks

DRUG

Nafcillin

Nafcillin is a semi-synthetic antibiotic related to penicillin. Nafcillin (2 g will be administrated intravenously (IV) every 4 hours for 4-6 weeks)

DRUG

Oxacillin

Oxacillin is an antibiotic used in resistant staphylococci infections. Oxacillin (2 g will be administrated intravenously (IV) every 4 hours for 4-6 weeks

DRUG

Vancomycin

Vancomycin is a glycopeptide antibiotic product of the organism Amycolatopsis orientalis. Vancomycin (dose per local standard of care × 4-6 weeks)
