An interventional study of Blood culture sampling in Bacteremia Sepsis, sponsored by University Hospital, Grenoble. Recruiting at 2 sites in France. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-07-22.
Sponsored by University Hospital, Grenoble · Not applicable, Interventional, and Diagnostic
In the context of a bacteremia, although significant progress has been made in speeding up pathogen identification once a blood culture bottle turns positive, few cost-effective solutions have been proposed to improve the earlier stages of the process-specifically, from blood collection to bottle positivity. The investigators propose that transport time could be leveraged to grow and identify bacteria, enabling faster access to actionable results through innovative technologies. This project aims to develop a bacterial identification database by analyzing the electrochemical profile of bacteria growing within the blood culture bottle, using machine learning.
297 studies on the registry are indexed under Bacteremia; 51 are open to participants now.
This study's planned enrollment of 200 is above the median of 156 across 156 interventional studies indexed under Bacteremia.

Exclusion Criteria:
Patients with blood culture sampling as standard of care. Two to four additional blood culture bottles sampled
Other: Blood culture sampling
Patients with blood culture sampling as standard of care. Two to four additional blood culture bottles sampled that will be spiked with known bacterial species to determine their electrochemical profiles
List of samples with an electrochemical profile
List of samples (bacterial strain and corresponding pseudonymized blood culture) for which an electrochemical profile of the growing bacteria within the blood culture bottle was successfully obtained
Time frame: From enrollment until the end of measurment of an electrochemical fingerprint in the blood cultures from the patient spiked with bacterial strains, assessed within up to one week after blood culture sampling
Identification performance
Identification performance of electrochemical profiling of the growing bacteria followed by machine learning analysis
Time frame: End of the study (18 months)
Plan to share: No
Started Jul 2026 (actual). Primary completion is estimated for Jan 2028, 18 months after the start.
Of 34 non-industry interventional studies with no phase under Bacteremia, half reached primary completion within 34 months of starting (the median), counting those still running; a quarter within 13 and three quarters within 64. This study's planned 18 months is below that.
Counting every sponsor, half of 35 studies reached it within 34 months; a quarter within 13 and three quarters within 64.
