NCT00440947
This study was designed to test the efficacy, safety, tolerability and durability of the antiviral response between atazanavir (ATV) + ritonavir (/r) + abacavir/lamivudine(ABC/3TC) Fixed dose combination (FDC) each administered once daily (QD) for 36 weeks followed by randomization to either a simplification regimen of ATV or continuation of ATV +/r for an additional 48 weeks, each in combination with ABC/3TC in antiretroviral (ART)-naive, HIV-1 infected, HLA-B\*5701 negative subjects. All subjects who complete the 84-week study will be eligible to enter the treatment extension phase and continue for an additional 60 weeks. The purpose of this extension is to obtain longer term treatment data in subjects who have completed the 84-week study.
NCT00711009
The purpose of this study is to compare the safety, tolerability, and antiviral activity of the lopinavir/ritonavir tablet when administered in combination with reverse transcriptase inhibitors to lopinavir/ritonavir tablets when administered in combination with a human immunodeficiency virus type 1 ( HIV-1) integrase inhibitor in antiretroviral naive HIV-1 infected subjects.
NCT00933933
To test blood specimens using a new investigational test that detects antigen and antibody to human immunodeficiency virus (HIV). Results will be compared to an approved HIV antibody test and supplemental testing performed to determine HIV status.
NCT00002429
This study tests a new form of didanosine, ddI EC, a coated pill that passes through the stomach before dissolving. The purpose of this study is to compare the effectiveness of an anti-HIV drug combination that includes ddI EC versus another anti-HIV drug combination.
NCT00002411
The purpose of this study is to compare the safety of didanosine plus stavudine plus nelfinavir (NLF) with that of zidovudine plus lamivudine plus NLF. This study also examines how long these drug combinations are effective in lowering viral load (level of HIV in the blood).
NCT00135447
The purpose of this study is to find out the frequency of the I50L substitution among patients experiencing treatment failure on an atazanavir-containing regimen.
NCT00067782
The purpose of this clinical research study is to learn if atazanavir is associated with serum LDL cholesterol in HIV-infected subjects following a substitution of atazanavir for their previously administered protease inhibitor.
NCT00002307
To compare stavudine (d4T) and zidovudine (AZT) in slowing the progression of HIV disease. To compare the antiviral activity of d4T versus AZT as measured by plasma levels of p24 antigen and HIV viremia, and their relative efficacy by improvement and/or absence of adverse changes over time in laboratory parameters associated with HIV infection. To compare the safety of oral doses of d4T to AZT in patients with HIV infection.
NCT00002224
Didanosine is an effective anti-HIV drug, but it can cause stomach upset. This study tests a new form of didanosine, ddI EC, a coated pill that passes through the stomach more easily and hopefully will prevent stomach upset. The purpose of this study is to compare the effectiveness of ddI EC versus the standard form of ddI. Both forms of ddI will be given with stavudine (d4T) plus nelfinavir (NLF).
NCT00002246
The purpose of this study is to see if adding stavudine (d4T) to anti-HIV drug regimens (with or without zidovudine, ZDV) can improve symptoms of AIDS Dementia Complex (ADC, problems involving the brain or spinal cord) in HIV-positive patients.
NCT00503347
This trial is designed to assess the safety, tolerability, pharmacokinetics and viral kinetics after multiple infusions of bavituximab in patients co-infected with HCV and HIV.
NCT00051844
This is a 48 week study that is intended for HIV Infected persons whose first treatment regimen was with a nonnucleoside reverse transcriptase inhibitor (NNRTI) and who are now failing that regimen. They must be currently on their failing regimen to be eligible.
NCT00004584
The purpose of this study is to look at the safety and effectiveness of an experimental protease inhibitor (a type of anti-HIV drug) called BMS-232632. Doctors will compare an anti-HIV drug combination that includes BMS-232632 to a drug combination that includes ritonavir.
NCT01484522
The purpose of this research study is to evaluate the immune response to the H1N1 influenza or "flu" vaccine. The "immune response" is how your body recognizes and defends itself against bacteria, viruses, and substances that may be harmful to the body. HIV-1 infected children typically respond more poorly to vaccines compared to uninfected, healthy children and so this study hopes to learn whether or not the body will successfully produce enough antibodies (proteins that fight infection) that will prevent or fight the H1N1 flu virus. There is no information yet on the safety or immune response to this vaccine in children infected with HIV.
NCT00002371
To compare the magnitude and durability of the reduction in plasma HIV RNA in the two treatment groups over the first 12 weeks of treatment. To determine the safety of each of the two treatment groups.
NCT00141284
The purpose of this study is to confirm the safety, efficacy and delineate the pharmacokinetic properties of nelfinavir in HIV/ Hepatitis C coinfected subjects with Child Pugh A compensated cirrhosis and or Hepatic fibrosis
NCT00131560
This study uses autologous (one's own) CD4 T cells modified with a viral vector expressing a genetic antisense targeting HIV, this vector is called VRX496. Study treatment is by intravenous infusion of vector modified cells and infusions will be provided every other week for a total of 4 or 8 doses. These modified cells, once infused, may provide immune support and are not destroyed by HIV, and thus may delay or reverse HIV disease progression. The study will enroll up to 40 male and female HIV-positive subjects in up to 8 centers. Subjects will be 18 years of age and over who have failed or are intolerant to at least one triple combination of antiretroviral drugs. Subjects must have a viral load between 5,000 and 200,000 copies/ml and a CD4+ count of ≥150, be in good health and have no evidence of active opportunistic infection, heart disease, or bleeding disorders. Subjects must not be on corticosteroids, immunomodulating agents or hydroxyurea. Subjects must not have received an AIDS vaccine or any investigational gene therapy product at any time. Females must not be pregnant or breastfeeding.
NCT00135343
The purpose of this study is to evaluate the safety and efficacy of a novel nucleoside sparing regimen containing atazanavir, ritonavir and efavirenz, using two different doses of atazanavir.
NCT00686205
To test blood samples from volunteer donors of whole blood and blood components using a new investigational test that detects human immunodeficiency virus (HIV) infection. Results will be compared to the current HIV screening assay.
NCT00782301
Confirm the safety of maraviroc when used as a component of combination antiretroviral therapy in HIV and Hepatitis co-infected patients.
