A study testing Telmisartan in people with Hypertension and Insulin Resistance, run by Stanford University at 1 site in United States.
Trial summary
In this study, we propose using telmisartan, an angiotensin II receptor antagonist with PPAR-gamma modulating activity, for a 12-week period to decrease blood pressure and insulin levels in obese, hypertensive children.

About this study
Official title: Randomized, Placebo Controlled, Double Blind Trial of Telmisartan in Hypertensive, Obese Adolescents
In this study, we propose using telmisartan, an angiotensin II receptor antagonist with PPAR-gamma modulating activity, for a 12-week period to decrease blood pressure and insulin levels in obese, hypertensive children. Telmisartan is currently approved for treatment of adult hypertension. Recent adult studies, however, have shown telmisartan as an effective medication for lowering insulin levels and improving insulin sensitivity. We will enroll 30 obese adolescents, ages 10 to 18 years, and randomly assign half of the group to receive telmisartan and the other half to receive placebo (sugar-pill). We will obtain fasting glucose and insulin levels, as well as other markers for insulin sensitivity and cholesterol panel, at the beginning of the study, at each clinic visit in 4-week intervals, and at the end of the study. We will obtain an imaging study (computed tomography, CT scan) on 10 randomly selected study patients (5 from each group) to examine the distribution of fat tissue before and after treatment. Studies suggest that fat tissue in the subcutaneous tissue is less harmful that fat tissues surrounding internal organs, such as the liver. We will also provide nutritional handouts and exercise recommendations to each participant as a life-style intervention. Each participant will be given a diary to record his or her diet and exercise activities throughout the study.

Hypothesis: This pilot study will provide data essential for designing a larger trial to test the hypothesis that telmisartan treatment of obese children with insulin resistance and hypertension will result in improved insulin levels and systolic blood pressure. Secondary outcome measures will include the effects of telmisartan on total cholesterol, triglyceride, HDL and LDL levels, body mass index (BMI), and body fat distribution.
Specific Aims for to Test Hypothesis:
Aim #1: Determine the change in insulin sensitivity in adolescents with obesity and hyperinsulinemia before and after treatment with telmisartan. We hypothesize a significant increase in insulin sensitivity following medical treatment. We will measure fasting insulin and glucose levels for calculation of the homeostasis model assessment (HOMA) [29, 30]. Furthermore, we will calculate parameters of insulin production and insulin resistance from simultaneous measurements of glucose, insulin, and C-peptide levels during an oral glucose tolerance test (OGTT). We will check IGF BP-1 (insulin-like growth factor 1 binding protein) level as an indirect measurement of insulin resistance. Due to the risks associated with glucose clamps and continuous insulin infusion, we will not use this procedure in our study.
Aim #2: Determine the change in systolic blood pressure in adolescents with obesity and hypertension before and after treatment with telmisartan. We hypothesize a significant decrease in systolic blood pressure following medical treatment. Subjects will have blood pressure checked at each clinic visit.
Aim #3: Evaluate changes in lipid profile and body mass index as secondary outcome measures with telmisartan treatment. Subjects will have weight, height, and fasting lipid panel checked at each clinic visit.
Aim #4: Characterize fat distribution before and after telmisartan treatment. A subset of study participants will undergo magnetic resonance imaging (MRI) to characterize and separate abdominal adipose tissue into its subcutaneous and visceral components. A one-slice MRI will be obtained at 2 time-points during the study (weeks 0 and 12).
Aim #5: Determine the feasibility of using telmisartan for the treatment of hyperinsulinemia and hypertension in obese adolescents. Study results will provide necessary data to calculate the power needed for a multi-center, randomized, placebo-controlled trial of telmisartan.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
In this study, we propose using telmisartan, an angiotensin II receptor antagonist with PPAR-gamma modulating activity, for a 12-week period to decrease blood pressure and insulin levels in obese, hypertensive children. Telmisartan is currently approved for treatment of adult hypertension. Recent adult studies, however, have shown telmisartan as an effective medication for lowering insulin levels and improving insulin sensitivity. We will enroll 30 obese adolescents, ages 10 to 18 years, and randomly assign half of the group to receive telmisartan and the other half to receive placebo (sugar-pill). We will obtain fasting glucose and insulin levels, as well as other markers for insulin sensitivity and cholesterol panel, at the beginning of the study, at each clinic visit in 4-week intervals, and at the end of the study. We will obtain an imaging study (computed tomography, CT scan) on 10 randomly selected study patients (5 from each group) to examine the distribution of fat tissue before and after treatment. Studies suggest that fat tissue in the subcutaneous tissue is less harmful that fat tissues surrounding internal organs, such as the liver. We will also provide nutritional handouts and exercise recommendations to each participant as a life-style intervention. Each participant will be given a diary to record his or her diet and exercise activities throughout the study.

Questions about this trial
What is this clinical trial studying?
A study testing Telmisartan in people with Hypertension and Insulin Resistance, run by Stanford University 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 4 inclusion and 1 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: stopped early, as of the sponsor's last update on 18 Mar 2020. 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.
Are results available for this study?
The study was stopped early (reason given: Primary investigator moved to different university). Results are not available in the source record.
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?
This pilot study will provide data essential for designing a larger trial to test the hypothesis that telmisartan treatment of obese children with insulin resistance and hypertension will result in improved insulin levels and systolic blood pressure.. 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 NCT00185705, which also lists 16 linked publications.
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 18 Mar 2020.
