Multiple-Dose Dalbavancin Regimens as the Predominant Treatment of Deep-Seated or Endovascular Infections: A Scoping...

Off-label use of dalbavancin for deep-seated and endovascular infections has been increasing. We performed a scoping review to evaluate the evidence for use of multiple-dose dalbavancin regimens as the predominant therapy for these indications. Predominant therapy was defined as use of dalbavancin without other concurrent antibiotics for more than half of the total treatment duration. Fifteen publications were identified; 2 were small, open-label randomized controlled trials and the remainder were retrospective observational studies or case reports. A total of 144 cases from these publications met eligibility criteria for inclusion in this review. Types of infections included osteoarticular infections, catheter-related or complicated bloodstream infections, and infective endocarditis. Overall, the evidence for use of multiple-dose regimens of dalbavancin for deep-seated and endovascular infections is limited by a paucity of data from controlled trials, heterogeneity of dosing regimens, and a lack of standardized clinical outcomes.
