  29. Insulin Resistance

    The Homeostatic Assessment Model of Insulin Resistance (HOMA-IR) is an index used to determine if insulin resistance is present. HOMA-IR is calculated as ([(fasting insulin in mU/L) x (glucose in mmol/L)]/22.5). Higher HOMA-IR values indicate greater insulin resistance. The threshold HOMA-IR value that indicates insulin resistance differs among different populations, but a common clinical cutoff is 2.6 (in other words, a HOMA-IR value of 2.6 or above is commonly interpreted to indicate insulin resistance).

    Measured: Baseline

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing B/FTC/TAF and Current ART in people with HIV Infections, run by The University of Texas Health Science Center, Houston 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 7 inclusion and 10 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 3 Oct 2022. 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.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Oct 2022). 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?

Frequency of Maintaining Undetectable HIV-1 RNA (time frame: 48 weeks). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 3 Oct 2022.
