Study summary

Activated monocytes play a key role in the pathogenesis of HIV-associated neurocognitive disorders (HAND). Individuals with HAND have expanded populations of activated monocytes. These monocytes are thought to emigrate into the CNS, where they produce neurotoxic proinflammatory factors, and also carry virus into the CNS. Statins are cholesterol lowering drugs with pleiotropic immunomodulatory / anti-inflammatory properties that are currently being explored for immunomodulation of T cell activation in several diseases, in addition to their established role to treat hyperlipidemia and atherosclerosis. The investigators in vitro data suggests that these drugs can downregulate monocyte activation patterns seen in HIV infection. No in vivo studies have yet been carried out to assess the effects of statins on the pro-inflammatory monocyte population in chronic HIV disease. This will be a pilot study of whether statin treatment will reduce the inflammatory monocyte phenotype and downregulate the inflammatory cytokines that have been linked to neuropathogenesis in HIV infection. If so, they may have potential as adjunctive therapy in HIV-associated neurological disease. The investigators propose to:

  • Determine the effect of Atorvastatin on peripheral blood monocyte populations in a 12-week pilot study in chronically HIV-infected people on HAART therapy.
  • Determine the relationship between changes in monocyte phenotype following Atorvastatin treatment, and soluble markers of activation/inflammation linked to neuropathogenesis, as well as activation status of T cells.

Terms in these criteria, in plain language(11)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

CD4 count

The number of CD4 cells, a type of white blood cell, in a given amount of blood. It is used to follow how well the immune system is doing in HIV.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

What researchers measure

Primary outcomes

  1. Change in Monocyte Surface Markers Expression (Expressed as Percentage), Following Treatment of Chronic HIV+/ HAART+ Subjects With Atorvastatin (T=12wks Versus T=0wk).

    Effects of Atorvastatin on immune activation associated surface markers (CD16, CD163 and CCR2) of monocytes were assessed in chronic HIV+/HAART+ subjects following 12 weeks of treatment. Whole blood drawn from these subjects were stained with fluorochrome tagged antibodies to the surface markers. Stained whole blood cells were then acquired on a flow cytometer and analyzed using the Flowjo software to determine the percentage of cells (monocytes) expressing the specific marker. This was done before starting and after completing drug treatment to assess the effect of drug.

    Time frame: Subjects enrolled in the study following the screening visit were assessed for the primary outcome measures at T=0 (drug intervention begins); T=12wks (intervention ends)

  2. Change From Baseline in Levels of Plasma Inflammatory Marker MCP-1 of Chronic HIV+/ HAART+ Subjects.

    Monocyte specific inflammatory soluble factor MCP-1 was measured by ELISA in plasma of HIV+/HAART+ subjects at baseline and at 12 weeks following atorvastatin treatment.

    Time frame: Subjects enrolled in the study following the screening visit were assessed for the primary outcome measures at T=0 (drug intervention begins); T=12wks (intervention ends)

  3. Change From Baseline in Levels of Plasma Inflammatory Marker sCD14 of Chronic HIV+/ HAART+ Subjects.

    Monocyte specific inflammatory soluble factor sCD14 was measured by ELISA in plasma of HIV+/HAART+ subjects at baseline and at 12 weeks following atorvastatin treatment.

    Time frame: Subjects enrolled in the study following the screening visit were assessed for the primary outcome measures at T=0 (drug intervention begins); T=12wks (intervention ends)

  4. Change From Baseline in Levels of Plasma Inflammatory Marker sCD163 of Chronic HIV+/ HAART+ Subjects.

    Monocyte specific inflammatory soluble factor sCD163 was measured by ELISA in plasma of HIV+/HAART+ subjects at baseline and at 12 weeks following atorvastatin treatment.

    Time frame: Subjects enrolled in the study following the screening visit were assessed for the primary outcome measures at T=0 (drug intervention begins); T=12wks (intervention ends)

Limitations and caveats
This study had a very small sample size of 5 subjects. Therefore due to lack of power the data is inconclusive.

Participant flow

Subjects were recruited from the AIDS Clinical Trial Unit (ACTU) at the Hospital of University Of Pennsylvania, Philadelphia, PA. The screening and recruitment process was carried out during the period September 2011 thru April 2012.

The record gives a start of Sep 2011, a primary completion of Oct 2017 and a completion of Oct 2017. It does not say whether these dates are actual or estimated.

Results were first posted in Apr 2019, 1 year 6 months after primary completion.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 1, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
