Oral Switch During Treatment of Left-sided Endocarditis Due to Multi-susceptible Staphylococcus

Brief description of study

Infective endocarditis (IE) is a serious infection with a significant burden for patients and hospitals (in France, median length of hospital stay = 43 days), partly due to the long duration of intravenous (IV) antibacterial treatment recommended by international guidelines, between 4 and 6 weeks in most situations.

A recent survey of practices regarding the management of IE in France showed that a switch from IV to oral antibiotics is feasible, when patients with left-sided Staphylococcus IE are stable after an initial course of IV antibiotic treatment, with or without valvular surgery.

These practices have not been associated with unfavourable outcome, while significantly reducing the duration and cost of hospitalization, the risk of nosocomial infection, and patients' discomfort.

There has been no randomized controlled trial (RCT) in the field of IE over the last 20 years; current guidelines are mostly based on expert advice, in vitro studies, animal experiments, or clinical studies performed before the 90's.

The RODEO 1 project is an unprecedented opportunity to bring back evidence-based medicine in the field of IE.

Most experts acknowledge that the pharmacological PK/PD characteristics of antibiotics such as fluoroquinolones and rifampicin allow a high level of efficacy in the treatment of IE when orally administrated after an IV period of induction.

It's needed to conduct RCTs that clearly demonstrate the clinical non-inferiority of this strategy for multisusceptible staphylococci with a benefit regarding costs.

The RODEO 1 project corresponds to one pragmatic trial assessing the impact of a switch strategy, making it a comparative effectiveness trial that should be able to feed the next revision of IE international guidelines and to change practices in IE management.

Detailed Study Description

The RODEO 1 study is designed to determine the safety and efficacy of partial oral treatment of IE compared with traditional full-length parenteral treatment. Our primary objective is to demonstrate that in patients with left-sided multi-susceptible Staphylococcus who have received at least 10 days of IV antibiotic treatment with or without valvular surgery, a switch to an oral combination of rifampicin and fluoroquinolones between Day 10 and Day 28 after initiation of the IV antibiotic treatment, is not inferior to the continuation of the conventional IV antibiotic treatment regarding to treatment failure within 3 months after the end of antibiotic treatment.

Nationwide, noninferiority, multicenter, randomized, controlled, open-label trials.

Randomisation will only be offered to patients who have received at least 10 days of IV conventional antibiotic treatment of IE, and fulfil the inclusion criteria.

Randomisation will take place between Day 10 and Day 28 after initiation of parenteral antibiotic therapy or valvular surgery, thus ensuring to have at least 14 days of oral therapy in the experimental group.

Patients will be eligible whether they have undergone valvular surgery or not. This will imply that surgery procedure prior to randomisation will be heterogeneous, but randomisation will be stratified on the requirement of valvular surgery as part of the treatment of the current episode of IE or not.
