Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved

Summary

This study tested whether patients with a serious heart valve infection (endocarditis) caused by staph bacteria could safely switch from intravenous (IV) antibiotics to oral pills after at least 10 days of IV treatment. The trial involved 162 adults with left-sided endocarditis. The goal was to see if the oral switch was as effective as continuing IV therapy, potentially allowing patients to leave the hospital earlier and reduce risks like hospital-acquired infections.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
levofloxacin and rifampicin (oral antibiotics)
What this could lead to
If successful, this could allow patients with certain heart infections to finish treatment at home with pills instead of staying in the hospital for IV antibiotics.
What could go wrong
This is a completed Phase 3 trial, but it only included patients with bacteria sensitive to the oral drugs. Results may not apply to all endocarditis cases, and oral antibiotics may not be as effective for everyone.

Inclusion Criteria: * Left-sided IE (Defined according to Duke criteria) on native or prosthetic valve * due to one isolate of Staphylococcus sp. (S. aureus or coagulase negative staphylococci, CNS) susceptible to levofloxacin and rifampicin * in an adult ≥18 year old * appropriate parenteral antibiotics treatment received for at least 10 days * in case of valvular surgery, appropriate parenteral antibiotics treatment received for at least 10 days after valvular surgery * planned duration of antibiotics will extend for at least 14 days at the time of randomisation i.e. a potential switch to oral treatment between Day 10 and Day 28 thus ensuring to have at least 14 days of oral therapy remaining in the experimental group * apyrexia (temperature \< 38°C) at each time point during the last 48 hours (at least two measures/day) at the time of randomisation * blood cultures have been sterile for at least 5 days at the time of randomisation * informed, written consent obtained from patient * subject covered by or having the rights to French social security Exclusion Criteria: * body mass index \<15 kg/m² or \> 40 kg/m² * glomerular filtration rate \< 50 ml/min/1,73m² * patient unable or unwilling to take oral treatment (digestive intolerance, significant malabsorption) at the time of randomisation * expected difficulties regarding compliance with oral antibiotic treatment or follow-up (e.g. severe cognitive impairment, severe psychiatric disease...) * patient without entourage to support and watch him at discharge * valvular surgery planned within the next 6 months * patients with cardiac devices (pace-maker, implantable cardiac defibrillator) and suspected device-related IE (vegetation on the leads) if removal of the device was not performed * breast feeding or pregnant women, or women on childbearing age without effective contraception * expected duration of follow-up \< 7 months at the time of randomisation (e.g. expected life expectancy \< 7 months, patient living abroad...) * past medical history of IE in the last 3 months * other infection requiring parenteral antibiotic therapy * taking of an estrogen-progesterone treatment interacting with rifampicin * patient with contra-indication to oral antibiotics administered in the experimental arm (i.e. fluoroquinolones or rifampicin ) - including anticipated non-manageable drug interactions with rifampicin, and allergy.
