Impact of Metabolite Supplementation to Restore Mitochondrial Dysfunction During Septic Shock: a Preclinical Study
An observational study of Septic Shock and Multiple Organ Failure, run by University Hospital, Angers at 1 site in France.
Trial summary
Septic shock is defined as a subset of sepsis with severe metabolism alterations, leading to organ failure. Septic shock is associated with a high mortality, around 40% according to the SEPSIS 3 definition. Metabolic alterations are responsible for lactic acidosis, and results in mitochondrial dysfunction.

About this study
Official title: Impact of Metabolite Supplementation to Restore Mitochondrial Dysfunction During Septic Shock: a Preclinical Study: MEFDASE Study
Septic shock is defined as a subset of sepsis with severe metabolism alterations, leading to organ failure. Septic shock is associated with a high mortality, around 40% according to the SEPSIS 3 definition.
Metabolic alterations are responsible for lactic acidosis, and results in mitochondrial dysfunction.

This study aims at evaluate the impact of exogenous metabolites on restoring mitochondrial function in septic shock patients with lactate acidosis.
Mitochondrial metabolism (quantitative analysis, mitochondrial function) in intact Peripheral Blood Mononuclear Cells (PBMC) will be isolate and analyse from patients at the early phase of septic shock (admission), at day 2 and 4. Participant's medical history will be recorded: renal and liver metabolism, severity scores and outcomes and the need for supportive care in the intensive care unit (ICU) until 28 days after admission.
Furthermore, the investigators will evaluate wether selected metabolites added to the cell culture medium may improve mitochondrial metabolism.
Read the detailed description
In this prospective study, the investigators will include patients admitted to the medical ICU of Angers University Hospital and meeting the SEPSIS-3 criteria for the definition of septic shock (Sequential Organ Failure Assessment (SOFA) score > 2, hyperlactatemia > 2 mmol/L and sepsis).
Blood samples will be collected during the usual care of initial resuscitation and analyzed in the laboratory INSERM (Institut national de la santé et de la recherche médicale) U1232 (University Hospital of Angers).
Mitochondrial metabolism will be analyzed in freshly isolated PBMC and after culture for 1-3 days, with or without the addition of selected metabolites to the cell culture medium.
The evolution of ketogenesis, mitochondrial function, acidobasic status will be assessed across the time (blood samples at day 2 and 4).
Survival, renal and liver metabolism, severity scores and outcomes and the need for supportive care in the intensive care unit (ICU) until 28 days after admission will be recorded.

What does the primary outcome measure?
Change in mitochondrial metabolism (mitochondrial membrane depolarization and respiration) with the supplementation of metabolite in the cell culture medium (time frame: Day 0 (whole blood after cells separation), Day 1-3 after cell culture). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 10 Aug 2026.
