CC-11050 in Human Immunodeficiency Virus-1-Infected Adults With Suppressed Plasma Viremia on Antiretroviral Therapy (APHRODITE)

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.
