NCT00085943
This study will compare the ability of fosamprenavir 700 mg with ritonavir 100 mg twice a day or lopinavir 400 mg with ritonavir 100 mg twice a day both combined with a fixed dose combination tablet of abacavir 600 mg and lamivudine 300 mg once a day to suppress virus levels of HIV to less than 400 copies/mL of blood. In addition we will study the safety and tolerability of these compounds over the 48 week study period in patients naive to anti-HIV therapy.
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.
NCT00246610
This study is an evaluation of the safety of 625 mg formulation when administered to HIV-infected pregnant women from their second trimester through six weeks postpartum. The study will also evaluate the pharmacokinetics of VIRACEPT
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).
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.
NCT00000979
To compare the effectiveness and toxicity of didanosine (ddI) and zidovudine (AZT) in patients with AIDS, advanced AIDS-related complex (ARC), or asymptomatic infection with CD4 counts \< 200 cells/mm3. AZT is effective in reducing mortality in patients with AIDS who receive the drug after the first episode of Pneumocystis carinii pneumonia (PCP) and in patients with advanced ARC. However, AZT therapy has been associated with significant toxicities. In addition, the effectiveness of AZT appears to decrease during the second and third years of therapy. For these reasons, the development of alternative therapy that would be at least as effective but less toxic is of great importance. The drug ddI is an antiviral agent that inhibits replication (reproduction) of HIV with less apparent toxicity than AZT.
NCT00116415
The purpose of this study is to evaluate whether a therapy with an all once daily regimen of efavirenz (EFV), didanosine (ddI)-EC and lamivudine (3TC) leads to improved outcomes, as measured by viral load, CD4 counts, adherence, safety, and tolerability.
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).
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.
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.
NCT00197197
The purpose of this study is to evaluate the safety and efficacy of the CCR5 antagonist GW873140 or placebo in combination with an optimized background regimen in treatment-experienced HIV-infected subjects with R5/X4-tropic virus
NCT00123890
The purpose of this study is to determine eligibility for one of three treatment studies of the CCR5 antagonist GW873140 or an observational study without GW873140. No investigational treatment will be administered through this study.
NCT00096746
This study will compare the response of subjects who failed a first-line ATV-containing regimen and who have the 150L-containing virus to subsequent protease inhibitor (PI)-containing therapy with that of a cohort who has failed a first-line reverse transcriptase inhibitor (NNRTI), and is subsequently receiving PI-containing therapy.
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.
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.
NCT00001017
To compare the safety and effectiveness of a new drug, fluconazole, with that of the usual therapy, amphotericin B, in the prevention of a relapse of cryptococcal meningitis (CM) in patients with AIDS who have been successfully treated for acute CM in the last 6 months. Cryptococcal meningitis is a life-threatening infectious complication of AIDS. Because relapse after treatment occurs in over 50 percent of cases, chronic maintenance therapy with intravenous (IV) amphotericin B is usually given. However, amphotericin B is not always effective, has toxic effects, and must be given by the intravenous route. Fluconazole is an antifungal agent that can be given orally and has been shown to be effective against cryptococcal infections in animals and against acute CM in a few AIDS patients. Also, the side effects experienced by over 2000 patients or volunteers given fluconazole have seldom been severe enough to require withdrawal of the drug.
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.
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.
NCT00162149
Open-Label, multiple-dose, drug interaction study to assess the effect of nevirapine on the pharmacokinetics of atazanavir in HIV-infected individuals.
