Bone, Inflammation, Gut and Renal Biomarkers in Antiretroviral Naïve HIV-1 Positive Subjects
A study testing blood and urinary samples in people with HIV Positive, run by Centre Hospitalier Universitaire de Saint Etienne at 1 site in France.
Trial summary
Co-morbidities, including low bone mineral density, increased visceral adiposity and chronic kidney disease (CKD) are frequent in people living with HIV, and may be driven by ongoing inflammation and immune activation. Read more about this study

About this study
Official title: Bone, Inflammation, Gut and Renal Biomarkers in Antiretroviral Naïve HIV-1 Positive Subjects Commencing Antiretroviral Therapy: the BIGgeR Study.
Co-morbidities, including low bone mineral density, increased visceral adiposity and chronic kidney disease (CKD) are frequent in people living with HIV, and may be driven by ongoing inflammation and immune activation. Initiation of ART reduces inflammation and immune activation and is associated with changes in bone and renal biomarkers and gut microbiota. Investigators hypothesise that changes in gut microbiome when starting antiretroviral therapy correlate to changes in bone and renal biomarkers and wish to explore possible mechanisms linking these by investigating changes in markers of inflammation and immune activation.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Co-morbidities, including low bone mineral density, increased visceral adiposity and chronic kidney disease (CKD) are frequent in people living with HIV, and may be driven by ongoing inflammation and immune activation. Initiation of ART reduces inflammation and immune activation and is associated with changes in bone and renal biomarkers and gut microbiota.

Questions about this trial
What is this clinical trial studying?
A study testing blood and urinary samples in people with HIV Positive, run by Centre Hospitalier Universitaire de Saint Etienne at 1 site in France.
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 5 inclusion and 6 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The record says: withdrawn, as of the sponsor's last update on 22 Nov 2023. 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 France. 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 withdrawn before enrolling participants, so there are no results.
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?
faecal microbial alpha-diversity (time frame: At 12 weeks). 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 22 Nov 2023; AzTrials last refreshed its copy on 8 Nov 2026.
