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.
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).
NCT00587912
The purpose of this study is to obtain clinical specimens from pathologists and physicians involved in the diagnosis and care of patients with AIDS and non-AIDS associated malignancies. The National Cancer Institute has set up a Bank for tissues and biological fluids from HIVpositive and HIV-negative individuals in order to have specimens available for scientists studying malignancies associated with HIV disease.
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.
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.
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.
NCT00000671
To compare the effectiveness and toxicity of didanosine (ddI) and zidovudine (AZT) in patients with AIDS or advanced AIDS-related complex (ARC) who have tolerated AZT therapy for 12 months or longer. Per amendment, asymptomatic patients with CD4 counts less than 200 cells/mm3 are eligible. 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 of HIV with less apparent toxicity than AZT. Studies indicate that ddI remains active in the body for at least 12 hours; thus benefits of ddI might be achieved with a low frequency of drug administration.
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.
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).
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
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.
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.
NCT00357240
The purpose of this clinical research study is to assess the effect of omeprazole at 20 mg on the pharmacokinetics of atazanavir administered as atazanavir with ritonavir relative to atazanavir or atazanavir/ritonavir in the absence of omeprazole in healthy subjects.
NCT00365339
The purpose of this clinical research study is to assess the pharmacokinetics of atazanavir, identifying one or more dosing regimens of atazanavir/ritonavir/tenofovir when dosed with famotidine results in atazanavir exposures similar to those when atazanavir/ritonavir/tenofovir 300/100/300 mg is dosed without famotidine in healthy subjects.
NCT00357721
The purpose of this clinical research study is to assess the pharmacokinetics of atazanavir administered twice-daily relative to historical data from atazanavir/ritonavir 300/100 mg, given once daily.
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.
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.
NCT00162149
Open-Label, multiple-dose, drug interaction study to assess the effect of nevirapine on the pharmacokinetics of atazanavir in HIV-infected individuals.
