About this study

Official title: A Phase II, Double Blind, Randomized, Exploratory Study of Chloroquine for Reducing HIV-Associated Immune Activation

HIV is characterized by frequent immune system activation. Early in the course of infection the body establishes an immune activation "set point" related to the amount of HIV in the blood stream. This set point affects the rate of CD4 cell loss. Without CD4 cells, or with very low levels of CD4 cells, the body cannot fight off illness. This is known as immunodeficiency. If left untreated HIV can lead to extreme immunodeficiency and AIDS.

Evidence suggests that by decreasing the rate of immune system activation, immune deficiency progression could be prevented. The purpose of this study is to learn how well chloroquine can reduce the level of immune activation and to test the safety and tolerance of chloroquine in people infected with HIV.

Read the detailed description

HIV is characterized by persistent immune system activation, and early in the course of infection the body establishes an immune activation "set point" related to the amount of HIV in the blood stream. This set point affects the rate of CD4 cell loss. Without CD4 cells, or with very low levels of CD4 cells, the body cannot fight off illness. This is known as immunodeficiency. If left untreated HIV can lead to extreme immunodeficiency and AIDS.

Immune system activation includes activating the CD8 cells. These cells attack body cells infected with viruses. Because of this, CD4 cells infected with HIV are frequently destroyed by CD8 cells. The purpose of this study is to learn how well chloroquine reduces the level of activation of CD8 cells in people infected with HIV. Increased activation of CD8 cells is thought to lead to a more severe path of disease in HIV infection.

The constant immune activation observed in HIV- infected patients has also been linked to higher levels of byproducts from certain naturally occurring bacteria found in the gut that are known to be immune stimulants. By decreasing the stimulation from these byproducts with chloroquine treatment, HIV disease may be slowed.

The purpose of this study was to learn how well chloroquine reduces the level of activation of CD8 cells and lowers the levels of bacteria byproducts in people infected with HIV, either off antiretroviral therapy (ART) (protocol version 1.0 dated December 17, 2008) or on-ART (protocol version 2.0 dated October 1, 2010). The off-ART (Arms A and B) and on-ART (Arms C and D) participants were enrolled during different time periods, and the study was designed to analyze the two study populations separately. This study also looked at how well chloroquine was tolerated and its safety in HIV- infected participants.

Off-ART participants in the study were randomized with equal probability to one of two treatment arms:

Arm A: Participants received 12 weeks of chloroquine treatment followed by 12 weeks of placebo

Arm B: Participants received 12 weeks of placebo followed by 12 weeks of chloroquine

On-ART participants in the study were randomized with equal probability to one of two treatment arms:

Arm C: Participants received 12 weeks of chloroquine treatment followed by 12 weeks of placebo

Arm D: Participants received 12 weeks of placebo followed by 12 weeks of chloroquine

Study treatment was given once a day for a full 24 weeks. There was an additional 4 weeks of follow-up for purposes of safety. After treatment has started, participants were asked to come to the clinic on Weeks 4, 10, 12, 16, 22, and 24. At each visit participants were given enough study treatment to last until the next visit. Each visit lasted between 30 and 60 minutes. At most visits, participants had a physical exam, answered questions about any medications they were taking and how they are feeling, and had blood drawn for safety to assess CD4/CD8 cell counts and viral load. Some additional blood were also stored for immunology testing. At some visits, participants were asked questions about their medication and medical history, had pupils dilated, had a hearing test, and had an electrocardiogram (EKG). Some visits required participants to arrive fasting. Pregnancy tests were also conducted if the participant is able to become pregnant or if pregnancy was suspected.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Chloroquine in people with HIV Infections, run by Advancing Clinical Therapeutics Globally for HIV/AIDS and Other Infections at 15 sites 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 18 inclusion and 18 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 13 Oct 2014. 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. 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 2014). 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 Percent CD8 HLA-DR+/CD38+ From Baseline to Week 12 (time frame: At pre-entry, entry, weeks 10 and 12). 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 NCT00819390, which also lists 4 linked publications.

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 13 Oct 2014.
