Septic ShockNCT01517815
Pharmacokinetic of Doripenem and Piperacillin/Tazobactam in More Than 120 kg Critically Ill Patients
A study testing Doripenem or Piperacillin/Tazobactam in people with Septic Shock, run by University Hospital, Montpellier at 1 site in France.
Trial summary
Overweight patients are susceptible to develop acute complications when they are admitted in an Intensive Care Unit (ICU). Severe infection can be associated with cardiovascular failure ('shock") and is associated with 35-50% mortality. One of the key issue to cure infection is to administer antibiotics.

About this study
Overweight patients are susceptible to develop acute complications when they are admitted in an Intensive Care Unit (ICU). Severe infection can be associated with cardiovascular failure ('shock") and is associated with 35-50% mortality. One of the key issue to cure infection is to administer antibiotics. However, under dosing antibiotic is one of the main reason that explain treatment failure. There are very few data concerning particularities of antibiotic dosing in critically ill, overweight, patients. The aim of the present study is to describe the pharmacokinetic of two main antibiotics (doripenem and piperacillin/Tazobactam) in both overweight and non overweight critically ill patients presenting a septic shock. The investigators hypothesis is that usual dose for those antibiotic may be accurate in non overweight patients but is not in overweight patients.
Read the detailed description
N=52 patients divided in 4*13 patients (13 per antibiotic and per group, overweight or non overweight).
Overweight is defined by a weight over 120kg. Antibiotic chosen by the intensivist in charge of the case. Doripenem 1g/8h with a 4h IV infusion whatever the patient's weight. Piperacillin/Tazobactam 4g IV (1h) and then 16g/24h IV continuously whatever the patient's weight.
Piperacillin/Tazobactam plasma dosage: after the first dose and then every 12h. Doripenem plasma dosage: after the first dose and then twice a day, at peak and residual value.
Usual plasma and urine samples for urea, creatinine, electrolytes, platelets and bilirubin each 24h.
Microbiology: bacterial identification and MIC measurement with E-test

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Overweight patients are susceptible to develop acute complications when they are admitted in an Intensive Care Unit (ICU). Severe infection can be associated with cardiovascular failure ('shock") and is associated with 35-50% mortality. One of the key issue to cure infection is to administer antibiotics.

Questions about this trial
What is this clinical trial studying?
A study testing Doripenem or Piperacillin/Tazobactam in people with Septic Shock, run by University Hospital, Montpellier at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 8 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 29 Nov 2016. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Time over MIC (calculated with the E-test) in overweight and non overweight critically ill patients (time frame: up to Day 8). 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 29 Nov 2016; AzTrials last refreshed its copy on 8 Nov 2026.
