A Phase 4 interventional study of Antibiotics and Antibiotics in Endocarditis, Bacterial, sponsored by Carmen Olmos Blanco. Terminated at 1 site in Spain. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2023-09-28.
Sponsored by Carmen Olmos Blanco · Phase 4, Interventional, and Treatment
Background: it is well known that most serious complications of infective endocarditis (IE) appear in the so-called "critical phase" of the disease, which are the first days after diagnosis. Subsequently, the vast majority of patients who overcome this acute phase has a favourable evolution, and usually stay in the hospital for a long time only to complete antibiotic therapy.
In stable patients with adequate response to antibiotic treatment, without signs of persistent infection or metastatic foci such as spondylodiscitis, it is likely that a shorter antibiotic regimen would be an efficient and safe alternative, as has already been confirmed in patients with IE on tricuspid valves caused by a microorganism considered virulent such as S. aureus. This attractive alternative would improve patients' quality of life, save costs, and decrease the risk of complications related to the adverse effects of prolonged antibiotic treatment.
Objectives: to compare the incidence of the composite endpoint of all-cause mortality, unplanned cardiac surgery, symptomatic embolisms and relapses within 6 months after the inclusion between patients with IE caused by gram-positive cocci receiving a short-course of 2 weeks of antibiotic therapy and those patients receiving conventional antibiotic therapy (4-6 weeks).
Methodology: multicenter, prospective, randomized, controlled open-label, phase IV clinical trial. Sample: patients with IE caused by gram-positive cocci, having received at least 10 days of conventional antibiotic treatment, and at least 7 days after surgery when indicated, without clinical, analytical, microbiological or echocardiographic signs of persistent infection. Estimated sample size: 298 patients. Intervention: Control group: standard antibiotic therapy, according to ESC guidelines recommendations, for 4 to 6 weeks. Experimental group: short-course antibiotic therapy for 2 weeks. The prevalence of previously known risk factors for adverse events will be compared between the two groups to confirm that randomization have worked properly. The incidence of the composite endpoint of all-cause mortality, unplanned cardiac surgery, symptomatic embolisms and relapses within 6 months after the inclusion in the study will be prospectively registered and compared.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).
Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
