Methods for Measuring Insulin Sensitivity
NCT00001625 · View on ClinicalTrials.gov ↗
Study Summary
Patients with high blood pressure, diabetes, and who are overweight are known to have defects in the way their body responds to insulin. The purpose of this study is to develop better methods for measuring the way body tissue responds to insulin and sugar (glucose). Researchers are planning to study four groups of patients. 1. Normal volunteers 2. Patients who have mild to moderate high blood pressure 3. Patients who are overweight 4. Patients who have mild to moderate diabetes controlled with oral medication In this study patients and volunteers will undergo two separate tests designed to determine how well insulin is working in the body. The first test is called a glucose clamp test. Patients will have two needles placed in the veins of their arms. One needle will be used to take blood samples, the other needle will be used to inject doses of sugar (glucose) and insulin. The second test is called the frequently sample intravenous glucose tolerance test. In this test patients will have sugar (glucose) injected into their veins followed by a slow injected dose (infusion) of insulin. Researchers will periodically take blood samples during the test. Patients participating in the study will not directly benefit from it. However, the information gained from this study may be useful for improving the diagnosis and therapy of diseases such as diabetes, obesity, and high blood pressure (hypertension).

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00001625
The ClinicalTrials.gov registry entry for NCT00001625 describes a study currently listed as completed. It is categorized as an unspecified phase, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 480 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Center for Complementary and Integrative Health (NCCIH), which has 55 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Obesity appearing as the primary indexed condition, and to 0 interventions. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00001625 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
