Brief Summary
The purpose of this study is to determine whether pharmacologic inhibition of Toll-like receptor 4 (TLR4) with eritoran for injection (E5564) prevents lipid-induced insulin resistance in lean, normal glucose tolerant (NGT) subjects.

Outcome Measures
Primary Outcomes (2)
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.
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.
72 hours
Secondary Outcomes (3)
Effect of Eritoran on TLR4 Expression on Peripheral Blood Monocytes
72 hours
Effect of Eritoran on Plasma Cytokine Concentration
72 hours
Effect of Eritoran on Intramyocellular Diacylglycerol and Ceramide Content
72 hours

D5W (5% Dextrose in water) + Saline
ACTIVE COMPARATORIV administration of 5% Dextrose in water/D5W (vehicle) 12 mg every 12 hours plus Saline infusion at a rate of 30 mL/hour
D5W (5% Dextrose in water) + Intralipid
ACTIVE COMPARATORIV Administration of 5% Dextrose in water /D5W (vehicle) 12 mg plus Intralipid infusion at a rate of 30 ml/hour
Eritoran + Intralipid
ACTIVE COMPARATORIV administration of Eritoran 12 mg every 12 hours plus Intralipid infusion at a rate of 30 ml/hour
Interventions
Eritoran = E5564 Eritoran is a pharmacologic inhibitor of TLR4.
D5W = 5% Dextrose Water Vehicle
Eligibility Criteria
You may qualify if:
- Subjects capable of giving informed consent.
- lean (BMI \<26 kg/m2)
- normal glucose-tolerant subjects (completers) without a family history of Type 2 diabetes mellitus (DM)
- Both genders. (50% males)
- Age = 18-65 years. Older subjects are excluded because aging is a pro-inflammatory state.
- All ethnic groups
- Premenopausal women in the follicular phase, non-lactating, and with a negative pregnancy test. Postmenopausal women on stable dose of or not exposed to hormone replacement for \>=6 months.
- Lab: Hematocrit \>=34%, serum creatinine \<=1.4 mg/dL, normal electrolytes, urinalysis, and coagulation tests. Liver function tests up to 2x normal range.
- Stable body weight (+/-1%) for \>=3 months.
- One or less sessions of strenuous exercise/wk for last 6 months.
You may not qualify if:
- Presence of diabetes or impaired glucose tolerance based on ADA criteria;
- Current treatment with drugs known to affect glucose and lipid homeostasis. Subjects on a stable dose of statin (\>3months) are eligible.
- Non-steroidal anti-inflammatory drugs or systemic steroid use for more than 1 week within 3 months.
- Current treatment with anticoagulants (warfarin). Aspirin (up to 325 mg) and clopidogrel will be permitted if these can be held for seven days prior to the biopsies.
- History of heart disease (New York Heart Classification greater than class II; more than non-specific ST-T wave changes on the ECG), peripheral vascular disease, pulmonary disease, smokers.
- Poorly controlled blood pressure (systolic BP\>160, diastolic BP\>90 mmHg).
- Active inflammatory, autoimmune, infectious, hepatic, gastrointestinal, malignant, and psychiatric disease.
