About this study
Official title: Oral Switch During Treatment of Left-sided Endocarditis Due to Multi-susceptible Streptococcus (Relais Oral Dans le Traitement Des Endocardites à Streptocoques Multi-sensibles)
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 Streptococcus-Enterococcus 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 2 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 amoxicillin 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 streptococci, and enterococci IE with a benefit regarding costs.
The RODEO 2 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.
Read the detailed description
The RODEO 2 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 Streptococcus-Enterococcus IE who have received at least 10 days of IV antibiotic treatment with or without valvular surgery, a switch to an oral combination of amoxicillin 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.

Measured: up to 6 months after the end of antibiotic treatment
numer of participants with a switch back from oral to IV antibiotic treatment
For experimental group only . An assessment of the need for a return to parenteral antibiotic in the experimental group.
Measured: up to the end of antibiotic treatment
Compliance with oral antibiotic treatment
For experimental group only. The assessment of compliance with oral antibiotic treatment will be carried out at each visit during the treatment period though a "patient book" which will permit to note take/omissions of treatment; and though the return of the treatments to the pharmacy of the investigational site.
Calculation of the duration and cumulative dose of antibiotic treatment actually received will be performed, and compared to the regimen prescribed.
Measured: up to 4 weeks after randomisation

Measured: up to 6 months after the end of antibiotic treatment
Utility score and incremental cost-utility ratio (ICUR)
With data from all centers. An assessment of the health related quality of life of the patient will be carried out using a simple generic questionnaire, the EuroQol Five Dimensions (EQ5D3L), recommended by the Washington Panel on Cost Effectiveness (utility) in Health and Medicine, with a cardinal scale and validated French version (http:// www.euroqol.org)Quality of life will be assessed 4 times: at baseline, at the end of antibiotic treatment, at 3 months after end of antibiotic treatment and at the final visit
Measured: up to 6 months after the end of antibiotic treatment

What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Treatment failure (time frame: up to 6 months after the end of antibiotic treatment). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02701595, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Feb 2026.
