Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Background:

When there is a threat to the body, the immune system triggers inflammation. Too much inflammation can damage the body or cause painful symptoms. Some people with HIV feel sick after they start HIV drugs because their recovering immune systems cause too much inflammation. Or their immune systems can become activated all the time. This can cause serious health problems. Researchers want to test if the drug CC-11050 helps treat inflammation in people taking HIV drugs.

Objectives:

To test if CC-11050 is safe and well-tolerated for people with HIV who are taking HIV drugs. To see if it reduces inflammation.

Eligibility:

People ages 18 and older with HIV who have been on antiretroviral therapy for at least 1 year.

Design:

Participants will be screened with:

Medicine review

Physical exam and medical history

Blood and urine tests

Chest x-ray

Electrocardiogram (ECG): Soft electrodes on the skin record heart signals.

Participants will be randomly assigned to take capsules of either CC-11050 or a placebo. They will take the capsules every day for 12 weeks. They will continue to take their HIV drugs.

Participants will have a baseline visit within 2 months of screening. This includes:

Physical exam and medical history

Blood and urine tests

ECG

Leukapheresis: Blood is removed by a needle in one arm and passed through a machine that removes white blood cells. The rest of the blood is returned through a needle in the other arm.

Participants will have follow-up visits 2, 4, 8, 12, and 16 weeks after the baseline visit. These may include repeats of some of the baseline tests.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

CC-11050 is a novel anti-inflammatory compound with potential to treat a variety of chronic inflammatory conditions and cytokine storms associated with infectious diseases. CC-11050 is a selective phosphodiesterase-4 inhibitor (PDE4) that is active in several in vivo models of inflammatory disease, inhibiting systemic TNF- production, colitis symptoms of the colon, psoriasiform features in the skin, arthritogenic swelling in the joints, neutrophilia and eosinophilia in the lung, and reducing choroidal neovascularization. These data suggest that CC-11050 may have therapeutic potential for chronic inflammatory conditions and/or as an antiangiogenic treatment. The safety profile of CC-11050 has been investigated in healthy males and in subjects with cutaneous lupus erythematosus; the most frequently reported adverse events were fatigue, headache, upper respiratory infection and pruritus; there were no deaths or serious adverse events.

Inflammation is an important contributor to HIV pathogenesis both prior to and after ART initiation. Inflammatory responses can occur abruptly upon ART initiation (known as immune reconstitution inflammatory syndrome or IRIS) and can be chronic in persons with suppressed plasma HIV viremia who are treated with ART, and has been linked to an excess risk of non-AIDS serious events such as cardiovascular, liver and kidney disease and accelerated bone loss. Corticosteroids to reduce levels of inflammatory cytokines in plasma are a standard therapeutic intervention for IRIS, however a more targeted anti-inflammatory and less broadly immunosuppressive intervention is desirable.

We propose a double-blind, randomized trial to assess the safety of CC-11050 in adults with HIV infection who have taken ART for at least 1 year and have suppressed plasma viremia. Enrolled subjects will be randomized 2:1 to 200 mg CC-11050 or placebo twice daily for 12 weeks. Participants will be evaluated at weeks 0, 2, 4, 8, 12 and 16. Changes in in plasma HIV-1 RNA levels (by clinical assay), CD4+ T cell counts and percentages, and the effect on markers of systemic inflammation (e.g., TNF, IL-6, CRP, IFNg, sCD14, D-dimer) will be measured. The effect of CC-11050 on cellular immune activation (T cells and monocytes), and on viral reservoirs (cell associated HIV DNA and RNA) will also be assessed.

7. Willingness to allow storage of specimens for future analysis
8. Negative serum or urine pregnancy test (for women of childbearing potential)
9. Under the care of a primary care physician outside of the NIH

Contraception: The effects of CC-11050 on the developing human fetus are unknown. For this reason, subjects must agree to not become pregnant. Females of childbearing potential must have a pregnancy test before initiating the study agent and at each study visit. Because of the risk involved, male and female study participants who engage in sexual activities that can result in pregnancy must agree to use of a male or female condom at every potentially reproductive sexual encounter, AS WELL AS one of the other methods listed below, beginning at the baseline visit and continuing until 3 months after discontinuation of the study agent. Acceptable methods are as follows:

* Hormonal contraception \[e.g. consistent use of oral contraceptive pill daily or other hormonal method such as contraceptive implant or injection\] (must be started 1 month prior to receiving the first dose of study agent)
* Diaphragm or cervical cap
* Intrauterine device (IUD)
* Male partner with a vasectomy

During the study, if a participant becomes pregnant or suspects they are pregnant, they should inform the study staff and their primary care physician immediately. The study medication will be stopped immediately and if on CC-11050 they will be referred to a high risk pregnancy specialist and followed by the study team for the remainder of the pregnancy or the rest of the study, whichever occurs later.

Exclusion Criteria

1. Body mass index (BMI) less than or equal to 18.5 kg/m2
2. Protease inhibitor-based ART regimen
3. ART regimen which includes Cobicistat
4. Absence of alternate available ART options in case of virologic failure
