Can a tailored antibiotic regimen shorten endocarditis treatment without risk?
NCT ID NCT05144399
First seen Jul 23, 2026 · Last updated Jul 24, 2026 · Updated 1 time
Summary
This trial investigates whether a shorter course of antibiotics, tailored to each patient's response, can treat left-sided endocarditis as safely as the standard 4-6 week regimen. Adults with endocarditis caused by specific bacteria (Streptococci, Enterococcus faecalis, or Staphylococcus aureus) receive an accelerated treatment plan based on their individual clinical data. The goal is to reduce hospital stays and associated risks while maintaining effectiveness.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- accelerated antibiotic treatment tailored to individual response
- What this could lead to
- If successful, this could shorten hospital stays and reduce risks like mental strain and loss of function for patients with endocarditis, while saving healthcare costs.
- What could go wrong
- This is an early-stage trial testing a non-inferiority approach, so the shorter treatment might prove less effective or safe than standard care. Results are not yet available.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Patients hospitalized and diagnosed with bacterial, left-sided endocarditis as determined by the department clinician responsible based on the revised Duke criteria. 2. The patient may be included \<14 days after beginning of relevant antibiotic treatment. 3. Left-sided endocarditis with one of the following microorganisms: Streptococci; Enterococcus faecalis; Staphylococcus aureus. 4. Patients ≥ 18 years. Exclusion Criteria: 1. Known / suspected immunocompetence (HIV, chemotherapy, prednisolone treatment (\> 20 mg / day)). 2. Incapability to give informed consent for participation. 3. Relapse Endocarditis (Endocarditis with the same bacteria within six months).
