Daptomycin in the Clinical Setting: 8-Year Experience with Gram-positive Bacterial Infections from the EU-CORE(SM) Registry

The aim of this study was to evaluate the clinical outcomes and safety of daptomycin therapy in patients with serious Gram-positive infections.

Methods: Patients were enrolled in the European Cubicin® Outcomes Registry and Experience (EU-CORESM), a non-interventional, multicenter, observational registry. The real-world data were collected across 18 countries (Europe, Latin America, and Asia) for patients who had received at least one dose of daptomycin between January 2006 and April 2012. Two-year follow-up data were collected until 2014 for patients with endocarditis, intracardiac/intravascular device infection, osteomyelitis, or orthopedic device infection.

Results: A total of 6075 patients were enrolled. The most common primary infections were complicated skin and soft tissue infection (31.7%) and bacteremia (20.7%). Staphylococcus aureus was the most frequently reported pathogen (42.9%; methicillin-resistant S. aureus [MRSA], 23.2%), followed by Staphylococcus epidermidis and other coagulase-negative staphylococci (CoNS, 28.5%). The most commonly prescribed dose of daptomycin was 6 mg/kg/day (43.6%), and the median duration of therapy was 11 (range 1-300) days. Overall clinical success rate was 80.5%, and was similar whether daptomycin was used as first-line (82.9%) or second-line (79.2%) therapy. Clinical success rates were high in patients with S. aureus (83.9%; MRSA 83.0%) and CoNS (including S. epidermidis, 82.5%) infections. The majority of patients with endocarditis or intracardiac/intravascular device infection (86.7%) or osteomyelitis/orthopedic device infection (85.9%) had a sustained response during the 2-year follow-up period. There were no new or unexpected safety findings.

Conclusion: Results from real-world clinical experience showed that daptomycin is a valuable therapeutic option in the management of various difficult-to-treat Gram-positive infections.
