    Time frame: Outcome is measured at the end of follow-up (usually between 12 and 24 months after antibiotic therapy disruption

Secondary outcomes

  1. Rate of Treatment Failure

    Treatment failure is defined by local clinical and/or microbiological relapse; and/or need for additional surgery; death of septic origin. Analyse of risk factor.

    Time frame: Outcome is measured at the end of follow-up (usually between 12 and 24 months after antibiotic therapy disruption

  2. Duration of antibiotics

    Description of the strategies of antibiotic treatments used (double-agent therapy, monotherapy, duration)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Dec 11, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
