Ampicillin and Ceftriaxone for the Treatment of Enterococcus Faecalis Infective Endocarditis.

Efficacy and Safety of Ampicillin and Ceftriaxone Continuous Infusion Versus Standard Therapy for the Treatment of Enterococcus Faecalis Infective Endocarditis (DOβLEI Study)

Phase IV, open-label, randomized and multicenter clinical trial to prove that patients with Enterococcus faecalis infective endocarditis treated with an antibiotic treatment as a continuous infusion is non-inferior to the standard treatment, usually administered in hospitalized patients.

The aim of the study is to prove that the continuous infusion of antibiotic treatment for the patients with Enterococcus faecalis infective endocarditis is as effective and safe as the standard treatment. The continuous infusion modality of treatment is expected to provide numerous benefits for individual patients, global health, and for the National Health Care System by reducing to hospital stays from 4-6 weeks to approximately 2-3 weeks and hospital-driven complications.

The mortality, rate of serious adverse events, total number of days of antibiotic treatment and days of hospitalization, among others, are included as secondary objectives.

This is a pragmatic study as the number or visits performed for the study are similar to the normal clinical follow-up for this patients. Final contact and final visit for the study will be performed at 365 days after the 42 days of treatment.
