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.
Clinical Details
Official title: The Role of TLR4 on Lipid-Induced Insulin Resistance
Study design: Endpoint Classification: Efficacy Study, Intervention Model: Single Group Assignment, Masking: Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Primary Purpose: Treatment
Primary outcome: Effect of Eritoran on muscle insulin actionEffect of Eritoran on hepatic insulin sensitivity
Secondary outcome: Effect of Eritoran on Inflammatory signaling in muscleEffect of Eritoran on TLR4 expression on peripheral blood monocytes Effect of Eritoran on Plasma cytokine concentration Effect of Eritoran on Intramyocellular diacylglycerol and ceramide content
Detailed description:
E5564 = Eritoran
Eligibility
Minimum age: 18 Years.
Maximum age: 65 Years.
Gender(s): Both.
Criteria:
Inclusion Criteria:
- 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.
Exclusion Criteria:
- 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.
