简要总结
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.

入选标准
- •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.
排除标准
- •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.

结局指标
主要结局
Effect of Eritoran on Muscle Insulin Sensitivity
时间窗: 72 hours
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.
Effect of Eritoran on Hepatic Insulin Sensitivity
时间窗: 72 hours
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.
