  • Ages 18 to 80 years
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • NOTE: The term "licensed" refers to a US FDA-approved kit, which is required for all IND studies.
  • CDC (Centers for Disease Control and Prevention) guidelines mandate that confirmation of the initial test result must use a test that is different from the one used for the initial assessment. A reactive initial rapid test should be confirmed by either another type of rapid assay or an E/CIA that is based on a different antigen preparation and/or different test principle (eg, indirect versus competitive), or a Western blot or a plasma HIV-1 RNA viral load.
  • Receiving ART therapy for at least 12 months prior to study entry.
  • No plans to change the ART regimen in the 6 months after study entry.
  • HIV-1 RNA below the lower limit of detection using an FDA-approved assay obtained within 30 days prior to study entry by any laboratory that has a CLIA certification or its equivalent (eg, <50 copies/mL on Roche Amplicor HIV-1 Monitor assay, <75 copies/mL on the Versant HIV-1 RNA assay by branched DNA, <40 copies/mL on the Abbott m2000sp/m2000rt real-time PCR test, < 20 copies/mL on the COBAS AmpliPrep/TAQMAN HIV-1 assay).

About this study

Official title: A Prospective Randomized Controlled Study to Evaluate the Effect of Isotretinoin on Immune Activation Among HIV-1 Infected Subjects With Incomplete CD4+ T Cell Recovery on Suppressive Antiretroviral Therapy (ART)

This phase II study was done in HIV-infected participants on antiretroviral therapy to evaluate the effects of isotretinoin (a drug that is approved for use in the treatment of severe acne) on the immune system. The immune system helps the body fight infections. When the immune system is not working well, one may be at greater risk for diseases that are common in aging, like heart disease, weaker bones, and kidney disease.

Read the detailed description

Isotretinoin was administered to participants in the Isotretinoin arm at approximately 0.5 mg/kg PO once daily for 4 weeks, then increased to approximately 1.0 mg/kg PO once daily for 12 weeks. Follow-up continues to week 28 to evaluate the duration of effect. Randomization was stratified by willingness to participate in the gut biopsy substudy, A5330s. The study population included HIV-1 infected adults whose virus was suppressed on ART, excluding women of child bearing potential.

What is being measured

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

  1. Change in CD8+ T-cell Activation From Baseline to Week 14/16

    Level of CD8+ T-cell activation was determined by measuring the percentage of CD8+ T-cells that expressed both the activation marker CD38+ and Human leukocyte antigen (HLA)-DR+. The endpoint is measuring the change from baseline to week 14/16, where baseline is defined as the average of pre-entry and entry, and week 14/16 is defined as the average of week 14 and week 16.

    Change = (week 14/16 - baseline).

  12. Change in Cell-associated HIV-1 RNA

    Cell-associated HIV-1 RNA in blood from baseline to week 14/16(week 14/16 - baseline), from week 14/16 to week 28 (week 28 - week 14/16), and from baseline to week 28 (week 28 - baseline).

    Levels measured at pre-entry and entry were averaged for baseline, levels measured at week 14 and week 16 were averaged for week 14/16.

    For cell-associated HIV-1 RNA results below the assay limit, the lowest value of the sample was imputed to these results (1.32 log10 copies/10^6 CD4 cells).

    Since there are only a few results below the assay limit, it is still reasonable to summarize the absolute changes for cell-associated HIV-1 RNA, where changes were calculated based on the imputed values (described above) for below assay limit results.

    Measured: baseline, week 14/16, week 28

  13. Cell-associated HIV-1 DNA

    For cell-associated HIV-1 DNA results below the assay limit, the lowest value of the sample was imputed to these results and considered lowest ranks (1.62 log10 copies/10^6 CD4 cells).

    It was originally planned to summarize the absolute changes for cell-associated HIV-1 DNA. However, since there are many results below limit of detection, analyzing the absolute changes would be inappropriate in this case.

    Instead, the baseline, week 14/16, and week 28 levels were summarized.

    Measured: baseline, week 14/16, week 28

  14. Change in Treg Frequency (%FoxP3+/CD25hi+/CD39+/CD127-(CD4+))

    Levels measured at pre-entry and entry were averaged for baseline, levels measured at week 14 and week 16 were averaged for week 14/16.

    Measured: baseline, week 14/16, week 28

  15. Change in Th17 Frequency (%IFNg-/IL17+(CD161+/CCR6+))

    Th17 (T-helper 17) cells are a subset of pro-inflammatory T helper cells defined by their production of interleukin 17 (IL-17).

    The outcome is the change in percent IFNg-/IL17+(CD161+/CCR6+) from baseline to week 14/16 (week 14/16 - baseline), from week 14/16 to week 28 (week 28 - week 14/16), and from baseline to week 28 (week 28 - baseline).

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Isotretinoin in people with HIV-1 Infection, run by Advancing Clinical Therapeutics Globally for HIV/AIDS and Other Infections at 15 sites in 2 countries.

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 34 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: finished, as of the sponsor's last update on 15 Oct 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 15 sites in United States, Puerto Rico. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 5 Sep 2017). 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?

Change in CD8+ T-cell Activation From Baseline to Week 14/16 (time frame: baseline, week 14/16). 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 15 Oct 2024.
