Clinical Trial Summary

The DALICATH study aim to demonstrate the non-inferiority of a single administration of 1500 mg of dalbavancin compared with standard documented antibiotic therapy for 14 days according to national guidelines.


Clinical Trial Description

Catheter-related bloodstream infections (CR-BSIs) are the most common nosocomial bloodstream infections, with an incidence as high as 8.5 to 19.8 infections per 1000 catheter-days. Staphylococcus aureus is involved in about 20% of CR-BSIs and associated with significant morbidity, mortality (9.3%), prolonged hospital stay (+ 9 days), and healthcare costs (35 000 € to 65 000 € per case). S. aureus CR-BSIs occurs mainly in frail patients with a port of catheter for chemotherapy or parenteral nutrition. According to international guidelines, management of CR-BSIs due to S. aureus includes the removal and replacement of the infected catheter and a 14-day intravenous (IV) antibiotic therapy. Therefore, the management of CR-BSIs due to S. aureus requires the insertion of a new intravenous catheter. In turn, the new catheter can also lead to new septic complications and limit the patients' autonomy. Non-adherence to these recommendations leads to over-mortality and costs. To date, it is not recommended to switch to oral antibiotics in such infections. Dalbavancin is a new glycopeptide antibiotic, with an excellent bactericidal activity against Gram-positive bacteria, especially S. aureus, and a prolonged half-life of 14 to 15 days. As a comparison, half-life of antibiotics usually used for CR-BSIs due to S. aureus, i.e. penicillin or glycopeptide, as-per sensitivity to methicillin is much lower: 1.5 to 9 hours. Such prolonged half-life allows one IV injection to be sufficient and effective over 14 days of treatment. This remarkable characteristic should allow patients to be promptly discharged from hospital without monitoring. The hypothesis is that in patients with CR-BSIs due to S. aureus, after catheter removal, dalbavancin could be administered intravenously in a single administration after catheter removal and be as effective as standard documented antibiotic therapy for 14 days according to national guidelines. ;
