Active clinical trials for "Acquired Immunodeficiency Syndrome"

This study is a Phase 2/3, multicenter, double-blind, randomized, parallel-group, placebo-controlled, dose-finding trial of Serostim® (mammalian cell-derived recombinant human growth hormone, r-hGH) versus placebo in subjects with human immunodeficiency virus-associated adipose tissue redistribution syndrome (HARS). The primary study objective is to determine whether Serostim® treatment reduces adipose tissue maldistribution more effectively than placebo. The primary co-endpoints are derived from measures of visceral adipose tissue assessed by computerized tomography (CT) and the ratio of trunk; and limb fat assessed by dual-energy X-Ray absorptiometry (DXA) scans. Anthropometric measures, physical exams, quality of life assessments, serial photographs, and various laboratory measures will be used to address secondary objectives. These secondary objectives relate to the impact of Serostim® on Physician and subject assessments of change in body shape, health-related quality of life, attitude towards medication compliance, metabolic markers, fat redistribution, and safety. On Day 1, eligible subjects will be randomized in a 1:1:1 ratio to receive daily Serostim®, Serostim® and placebo given on alternate days, or daily placebo. Serostim® doses will be based on body weight, with a maximum dose of 4 milligram (mg). Therapy will continue for 12 weeks. Treatment will then be altered and the new treatment will be continued through Week 24. Interim Study Visits will be required at Weeks 2 and 4 (Treatment Period 1) and at Weeks 14 and 16 (Treatment Period 2). Subjects will be offered to be enrolled into a maintenance Protocol (Study 23056) at Week 24.

This is a proof of concept (POC) single arm study of GW640385, a protease inhibitor, in combination with RTV and 2 or more nucleoside reverse transcriptase inhibitors (NRTI) backbone. This study has a 48 week duration and is open to both treatment naive and experienced patients who are HIV positive. There are 3 intensive pharmacokinetic (PK) visits.

The purpose of this study is to determine whether the HIV vaccine MRKAd5 HIV-1 gag/pol/nef followed by treatment interruption can increase immune system function in adults with acute or recent HIV infection who have started taking anti-HIV drugs.

The purpose of this study is to determine the effect of massage therapy on depression, quality of life and plasma cortisol levels in subjects with advanced HIV disease.

The purpose of this study is to evaluate the safety of the experimental drug Bay 50-4798 in HIV positive patients receiving HAART and to test the drug's effect on the CD4+ T-cell count.

This study will evaluate the effects of intermittent short cycles of HAART (highly active antiretroviral therapy) for treating HIV infection. HAART is a multi-drug regimen that is very effective in suppressing HIV and perhaps slowing or halting progression to AIDS. However, the treatment has significant drawbacks: it cannot completely rid the body of virus; long-term therapy carries a risk of toxicity (harmful side effects); and the regimen is difficult to comply with because many pills and capsules must be taken daily. When patients stop taking HAART, their HIV levels climb again. This study will see if giving HAART in short cycles of 7 days on, 7 days off, can keep viral levels low while maintaining CD4+ T cell counts. HIV-infected people age 18 or older who are receiving HAART and have a viral load of less than 50 copies/ml and a CD4+ T cell count of at least 175 cells/mm3 may be eligible for this study. Candidates will be screened with a medical history and physical examination, blood and urine tests, and possibly a chest X-ray and electrocardiogram. Women of childbearing potential will have a pregnancy test. Participants will be randomly assigned to either continue their current medication regimen or to take HAART in intermittent cycles of 7 days off, 7 days on. Patients will continue treatment for 72 weeks or until viral levels increase or CD4+ T cell counts decline to a level of concern. Upon entering the study, patients will have blood tests to monitor the amount of virus in the blood, CD4+ T cell count, viral resistance to HAART medications, side effects of the drug, and immune response to HIV in the test tube. They will have clinic visits for a history, physical examination and blood draws every month for 12 months. At that time, depending on T cell counts and viral load, the number of visits may be reduced, but never less frequently than every other month. Patients will also undergo leukapheresis-a procedure for collecting quantities of white blood cells-every 3 to 4 months while on the study. For this procedure, whole blood is collected through a needle in an arm vein (similar to donating blood). The blood is circulated through a cell separator where the white cells are removed, and the rest of the blood (plasma, red cells and platelets) is returned through the same needle or through a second one in the other arm. The collected white cells are used for special studies on the level and function of T cells and to detect hidden virus.

The purpose of this study is to look at the effectiveness of combination anti-HIV drug therapy (with protease inhibitors [PIs] or without) in patients with early HIV infections. This study also looks at whether a drug called interleukin-2 (IL-2) can boost the immune system of these patients. Doctors are not sure which anti-HIV drug combination is best to use in patients who have early HIV infection and have never received anti-HIV treatment. PIs are anti-HIV drugs that decrease viral load (level of HIV in the blood). However, PIs can cause serious side effects in some patients. Doctors would like to know if a drug combination that does not contain a PI is just as good as one that contains PIs.

Treatment of HIV repairs the immune system, but continuous treatment is expensive and causes side effects. Would it not be better to treat intermittently, e.g. stop treatment when the immune system has recovered, and start again only when damage reappears? That is the question which STACCATO proposes to answer. Approximately 500 patients were recruited for this trial from 2002 to 2004. One third were treated continuously; in two thirds, the treatment was interrupted whenever the CD4 count, a measure of immune recovery, exceeded 350. At the end of 2005, the two treatment groups will be compared in order to see which fared better regarding amount of drugs used, side effects, CD4 counts, and development of resistance to treatment.

This study will test the safety, side effects and anti-HIV activity of different doses of capravirine in children and adolescents with HIV infection. Capravirine belongs to a class of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs), which prevent the virus from replicating (making more copies of itself). Other NNRTIs are nevirapine, delavirdine and efavirenz. HIV-infected children between the ages of 4 months and 21 years may be eligible for this study if they: 1) have received less than 6 weeks of treatment with antiretroviral drugs; 2) have not benefited from antiretroviral therapy after 12 weeks of treatment; 3) cannot continue antiretroviral treatment because of harmful side effects. For the first week of the study, participants will have a 1-week "washout period" in which they will receive no anti-HIV therapy. During this time, they will have physical, eye and neuropsychologic examinations, blood and urine tests, echocardiogram, electrocardiogram (EKG), chest X-ray, head CT scan and skin tests. These physical exams and tests will be repeated throughout the study to determine changes in health. After the washout period, patients will take capravirine once a day in the morning for 6 days. After each dose, a small amount of blood will be drawn at 8 different times over 12 hours to measure the activity of the drug and HIV blood levels. A heparin lock will be placed in the vein to avoid multiple needlesticks. After the 6 days of capravirine there will be another washout period, this time for 21 days. During this time, doctors will determine the optimum combination therapy for the individual patient. After the second washout, patients will begin combination therapy with capravirine plus at least two other anti-HIV medicines. (These may include a reverse transcriptase inhibitor such as zidovudine, didanosine, lamuvidine, zalcitabine, or stavudine, and maybe one or more protease inhibitors such as ritonavir, nelfinavir, saquinavir, indinavir or amprenavir.) For the first week, patients will have a daily blood test to determine HIV blood levels. Afterwards, treatment will continue on an outpatient basis with clinic visits every 4 to 8 weeks for physical exams, lab tests and other procedures as required. The study will last approximately 48 weeks. Patients who benefit from capravirine therapy may be able to continue to receive the drug from the drug company sponsor or as part of another study, or the protocol for this study may be amended to lengthen the treatment period.

The purpose of this study is to see whether taking interleukin-2 (IL-2) and other anti-HIV drugs affects the course of HIV disease in patients with primary HIV infection (the time period that immediately follows infection with HIV). After primary HIV infection, the actual infection is spread through an increasing amount of HIV virus in the body. Studies have shown that, by taking a combination of anti-HIV drugs, it is possible to reduce the amount of HIV in the body to almost undetectable levels. This study will find out if starting anti-HIV drugs during primary infection will interrupt or reduce the spread of HIV in patients' bodies.
