GV-TH-01 is an open label Phase 1 study of 9 HIV-1 infected adults with suppressed viremia who started anti-retroviral therapy (ART) within 18 months of a negative HIV antibody test. This study has 3 phases. The first phase is the vaccination phase, where patients are vaccinated with pGA2/JS7 (JS7)DNA and MVA62B vaccines on a prime/boost regimen. The second phase of the study is a treatment interruption phase, whereby ART is interrupted for a 12 week period approximately 8 weeks following the last vaccination. The third phase occurs after the 12 week treatment interruption phase and is called the treatment reinstitution phase, because subjects reinstitute ART and are followed for an additional 24 weeks. The primary objective is to evaluate the safety of the vaccines during the three phases of the study. A secondary objective is to evaluate the immunogenicity of the vaccines during the vaccination phase of the study.
The study was conducted on people who were taking their first anti-HIV drug regimen (including an Non-Nucleoside Reverse Transcriptase Inhibitor (NNRTI), a type of anti-HIV drug) but the drugs in this regimen were not doing a good job of fighting their HIV infection. The main purpose of this study was to compare two other anti-HIV drug regimens to see how well they fight HIV. The study also looked at how well participants tolerate the drug regimens and how safe they are. The study was designed to determine whether taking the combination of lopinavir/ritonavir (LPV/r) plus raltegravir (RAL) works as well as what is usually used for second-line therapy: LPV/r plus the best-available nucleoside (nucleotide) reverse transcriptase inhibitor (NRTI) combination. Testing a regimen that does not include any NRTIs was important because NRTIs may no longer work for patients who received them as part of their first treatment regimen.
AIDS-related Kaposi's sarcoma (AIDS-KS) occurs in persons with HIV infection who are also infected with the Kaposi's sarcoma herpesvirus (KSHV). Several chemotherapy (anti-cancer) drugs work well in treating KS, but there is no treatment that cures KSHV infection. One chemotherapy drug called etoposide (VePesid®, ET) has caused KS tumors to get smaller in some people. Antiretroviral therapy (anti-HIV drugs or ART) is a group of medicines taken together to treat HIV infection. These medicines help to stop HIV from growing in the body. When this happens, the immune system, which fights infection and some cancers like KS, gets stronger. For some people, limited stage KS often improves or stays the same when they take ART. However, in some people KS continues to get worse when taking ART. These people may need chemotherapy at a later date. This study was done to find out if taking ART with immediate etoposide (ET) is better than taking ART alone or ART with delayed ET to treat limited stage KS. The study also tried to better understand KSHV and to see what kind of side effects are caused by ART and ET and how safe ART and ET are.
ACTG A5275 was a prospective, double-blind, randomized, placebo-controlled cross-over design pilot study evaluating the effect of atorvastatin on biomarkers of inflammation, coagulopathy, angiogenesis, and T-lymphocyte activation in HIV-1 infected individuals with suppressed HIV-1 RNA on stable protease inhibitor based antiretroviral therapy with fasting LDL cholesterol < 130 mg/dL. Atorvastatin is a drug approved by the Food and Drug Administration (FDA) for treating high cholesterol. Atorvastatin has also been able to lower the level of inflammation blood tests in certain other diseases but has not been studied for this purpose in people who have HIV. The main goal of this experimental study is to see how taking atorvastatin affects inflammation blood tests in people infected with HIV who do not need to take medicine for high cholesterol. In addition to observing the effects of atorvastatin on the level of inflammation measured in the blood, this study evaluated if atorvastatin is safe for people with HIV who are also taking medication for HIV.
The objective of the OPTIMAL study is to demonstrate that the adjunction of Maraviroc to a combination of antiretroviral therapy in naive and late diagnosed HIV-1 infected patients counts may accelerate the kinetics of immune restoration and decrease the risk of disease progression and death. It is a randomized, versus placebo, double-blind trial, conducted in France, Spain and Italy.
This is a randomized, double-blind, double-dummy, 48-week, comparative study. Approximately 150 HIV-infected, treatment-naïve patients with CCR5-tropic virus will be stratified by HIV-1 RNA: ≥100,000 copies/mL versus <100,000 copies/mL and will be randomized 2:2:1 to receive: - Arm A: CVC 100 mg (2 tablets, 50 mg each) QD + CVC matching placebo (2 tablets) QD + EFV matching placebo (1 tablet) QHS + FTC/TDF (1 tablet) QD. - Arm B: CVC 200 mg (4 tablets, 50 mg each) QD + EFV matching placebo (1 tablet) QHS + FTC/TDF (1 tablet) QD. - Arm C: CVC matching placebo (4 tablets) QD + EFV 600 mg (1 tablet) QHS + FTC/TDF (1 tablet) QD. Doses of both CVC/placebo and EFV/ placebo will be administered as double-blinded study drug. FTC/TDF will be administered as open-label study drug in a fixed-dose combination formulation (Truvada). CVC/placebo should be taken following breakfast; EFV should be taken on an empty stomach at bedtime. HIV-1 RNA levels and CD4+ and CD8+ cell counts, percentages, and ratios will be measured at every visit. Samples for viral tropism and resistance testing in case of virologic failure will be collected at Screening and each on-treatment visit. Biomarkers associated with inflammation and immune activation will be measured at Baseline (predose) and each study visit thereafter, with flow cytometry obtained at weeks 4, 12, 24, 48, and 52. Fasting metabolic indicators of glucose control (glucose and insulin for HOMA-IR, HbA1c) and fasting lipid profiles (HDL, LDL, total cholesterol, and triglycerides) will be measured at Baseline (predose) and Weeks 4, 12, 24, 48, and 52. Waist-to-hip ratios will be measured at Baseline and Weeks 24 and 48. Plasma samples will be collected and stored for possible future studies at Baseline (predose) and every visit thereafter.
The majority of Human immunodeficiency Virus (HIV)/Hepatitis C Virus (HCV) co-infected patients are non responders after 48 weeks of the current standard-of-care with Peg-Interferon/Ribavirin. The results of re-treatment are disappointing. The addition of Boceprevir to the current standard-of-care has been shown to increase the efficacy of therapy in HCV mono-infected patients previously treated with a bi-therapy. Knowing that HIV/HCV co-infected patients are subject to more rapid hepatic fibrosis as well as to increased risks of cirrhosis, end-stage liver disease and hepatocellular carcinoma, it is important to improve the response rate of the re-treatment of hepatitis C in these patients. The aim of this pilot study is to evaluate the efficacy and safety of Boceprevir in combination with Peg-Interferon alfa 2b plus ribavirin, in patients co-infected with HIV and chronic genotype 1 HCV, and previously treated with Peg-Interferon/Ribavirin. 80 subjects will be enrolled. The primary endpoint will be the Sustained Virologic Response (SVR) defined as undetectable HCV-RNA at Week 24 after the end of therapy.
The purpose of this study is to compare HIV RNA expression and infection within resting (CD4)+ cells in HIV-infected patients on stable ART before and after a single exposure to Vorinostat (VOR), after exposure to short intervals of VOR, and after repeated short interval exposure to VOR dosed over several weeks. Hypotheses: 1. The frequency of resting CD4+ T cell- associated HIV RNA (RCVL) will be increased following single and repeated exposure to VOR when given at appropriate intervals, and 2. That repeated exposure to VOR will reduce the frequency of HIV infection within resting CD4+ T cells (RCI)
Women sometimes develop cancer in an area called the cervix, which is the opening to the uterus, or womb. Women who have HIV are more likely to get this kind of cancer than women who do not have HIV. Nearly all of these cancers are caused by another virus, called human papilloma virus (or HPV). Other times, the cause of this cancer is not known. The investigators are looking for a better way to prevent cervical cancer. This study is comparing two different methods to prevent cancer of the cervix in women who have HIV. This study will also see if these methods are safe and tolerable in women who have HIV.
