What is being measured
The primary outcome is the main question the study is designed to answer.
Effect of Eritoran on Muscle Insulin Sensitivity
Muscle insulin sensitivity = muscle insulin sensitivity is determined by euglycemic hyperinsulinemic clamp procedure. M value (mg glucose / kg of body weight / minute) calculated from the clamp is measured. Higher M value indicates better insulin sensitivity. There is no established reference range.
Measured: 72 hours
Effect of Eritoran on Hepatic Insulin Sensitivity
Hepatic insulin sensitivity = is determined by euglycemic hyperinsulinemic clamp procedure. Endogenous glucose production or EGP (mg/kg/min) calculated from the clamp is measured. Lower EGP indicates better hepatic insulin sensitivity. There is no established reference range.
Measured: 72 hours
Secondary outcomes (3)
Effect of Eritoran on TLR4 Expression on Peripheral Blood Monocytes
TLR4 expression on the peripheral blood monocytes is determined by flow cytometry using arbitrary units. Higher TLR4 expression indicates higher inflammatory response. There is no reference range.
Measured: 72 hours
Effect of Eritoran on Plasma Cytokine Concentration
TNF-alpha levels (tumor necrosis factor-alpha) are determined by ELISA. Higher level indicates higher inflammatory response. There is no established reference range.
Measured: 72 hours
Effect of Eritoran on Intramyocellular Diacylglycerol and Ceramide Content
Intramyocellular diacylglycerol and ceramide content are determined by mass spectrometry. Higher levels have been associated with diabetes.
Measured: 72 hours

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Eritoran and D5W (5% Dextrose in water) in people with Insulin Sensitivity, run by The University of Texas Health Science Center at San Antonio at 1 site in United States.
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 10 inclusion and 7 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 8 Oct 2019. 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 United States. 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.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 8 Oct 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
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?
Effect of Eritoran on Muscle Insulin Sensitivity (time frame: 72 hours). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02321111, which also lists 1 linked publication.
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 8 Oct 2019.
