Trial summary

Rates of cardiovascular disease and diabetes are more than 2-fold greater in HIV infected people than the general population. Protease inhibitor booster antiretroviral therapy (PI-ART) which is used by ~50% of HIV infected people in the USA is an established risk factor for diabetes. Read more about this study

About this study

Rates of cardiovascular disease and diabetes are more than 2-fold greater in HIV infected people than the general population. Protease inhibitor booster antiretroviral therapy (PI-ART) which is used by ~50% of HIV infected people in the USA is an established risk factor for diabetes. Tauroursodeoxycholic acid (TUDCA), a naturally occurring bile salt, improves insulin sensitivity in HIV uninfected subjects, although the mechanisms for these benefits are unclear. This study will explore the hypothesis that TUDCA will improve insulin action in people with HIV who are receiving PI-ART. Further, this project will clarify the molecular mechanisms responsible for these improvements potentially benefiting society, irrespective of HIV status.

Read the detailed description

The purpose of this study is to determine if, and through which mechanisms, tauroursodeoxycholic acid improves insulin sensitivity in subjects with protease-inhibitor associated insulin resistance.

The investigators will perform body composition analysis by using a DEXA machine, liver fat measurement by using an MRI, and hyperinsulinemic euglycemic clamp procedures in 48 HIV infected, insulin-resistant/prediabetic subjects before and after 30 days of treatment with tauroursodeoxycholic acid or matching placebo. Biopsies of adipose tissue and skeletal muscle will be taken during fasting conditions and during insulin infusion, before and after treatment to measure markers of endoplasmic reticulum stress and thyroid hormone deiodinase.

Outcome measures:

The primary outcome measures will be change in glucose clearance during insulin infusion, change in markers of endoplasmic reticulum stress and change in content of D2 in muscle.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Tauroursodeoxycholic acidDrug

    Also called taurolite, tudcabil

    The intervention group will receive 1.75 grams of tauroursodeoxycholic acid daily for 30 days.

  • Placebo tabletOther

    The placebo group will receive a placebo tablet that is identical to the treatment group except that it does not contain tauroursodeoxycholic acid. The pills will be taken once daily for 30 days.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Glucose Uptake

    We will examine the ability of insulin to cause muscle to take up insulin. Each subject will receive intravenous insulin for 6 hours to see how much sugar needs to be given intravenously to keep the blood sugar normal, a measure called glucose uptake. We will compare glucose uptake measured as the amount of 20% dextrose that is needed to keep the blood sugar at ~100mg/dl during insulin infusion before and after 30 days of treatment with drug or placebo.

    Measured: Glucose uptake is measured at baseline and 30 days after study intervention

Secondary outcomes (3)
  1. Body Composition

    We will measure how much fat is present in each subject before and after treatment with TUDCA or placebo.

    Measured: Pre-Treatment and Post 30 day-Treatment

  2. Liver Fat

    We will use MRI to measure the relative (%) amount of fat in each subject's liver before and after 30 days of treatment. This will allow us to determine if the drug reduces liver fat. This is calculated by subtracting the amount of fat in the liver at the beginning of the study from the amount of fat in the liver after 30 days of treatment. Subjects who have claustrophobia or are unable to undergo MRI will not have this measure performed. Due to these reasons liver MRS was only performed in 10 patients in the tauroursodeoxycholic acid group and 9 subjects in the placebo group

    Measured: Pre-Treatment and Post 30 day-Treatment

  3. Liver Function Tests

    We will measure liver function tests before and after the study drug to ensure that no abnormalities in liver function occurs with the drug.

    Measured: Pre-Treatment and Post 30 day-Treatment

Questions about this trial

What is this clinical trial studying?

A study testing Tauroursodeoxycholic acid in people with HIV Related Insulin Resistance and Protease Inhibitor Related Insulin Resistance, run by Washington University School of Medicine 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 8 inclusion and 8 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: finished, as of the sponsor's last update on 27 Jan 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. Some participants in this study may receive a placebo. 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?

Yes. Results are posted in the registry (first posted 27 Jan 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Glucose Uptake (time frame: Glucose uptake is measured at baseline and 30 days after study intervention). 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 NCT01877551, which also lists 1 linked publication.

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 27 Jan 2020.
