NCT00000895
The purpose of this study is to determine if infection with Mycobacterium avium complex (MAC) occurs in other parts of the body before it is found in the blood. This study also evaluates the relationships between the amount of HIV in the blood, immune system functions, and the presence of MAC infection. HIV-positive patients are at risk for MAC infection because their immune systems have been weakened by HIV. It is hoped that aggressive treatment with anti-HIV drugs may improve their immune systems enough to prevent against MAC.
NCT00816062
The purpose of this study is to examine, through the endpoints established in this protocol, the long-term safety and effectiveness of the Talent Abdominal Stent Graft System, in a post-approval environment.
NCT00000893
Cohort I: The purpose of this study is to see how safe it is to combine 2 anti-HIV medications, efavirenz (EFZ) and nelfinavir (NFV) to treat HIV-positive children and to find an appropriate dose of EFZ to use in combination with NFV. Cohort II: The purpose of this study is to see how safe it is to give EFZ syrup combined with NFV and to measure the levels of EFZ and NFV in the blood. (This purpose reflects a change from the original since there are now 2 different cohorts of patients.) EFZ is an effective anti-HIV medication that easily can be combined with other drugs to treat HIV. This is an early study to determine a safe and effective dose for HIV-positive children. This study also will examine the correct dose of NFV to use in combination with EFZ.
NCT00000952
The study examines the safety and effectiveness of ritonavir (an anti-HIV drug), alone and in combination with other anti-HIV drugs, in HIV-positive children under 2 years of age. This study will also determine the most effective doses of ritonavir for future pediatric HIV studies. Infants infected with HIV by their mothers experience faster disease progression than adults or older children. Treatment with anti-HIV drugs administered at an early age may slow disease progression in infant populations.
NCT00000878
The purpose of this study is to evaluate the safety and tolerance of 2 anti-HIV drugs, d4T and 3TC, given in combination to HIV-positive pregnant women and their infants. Most HIV-positive pregnant women usually take the anti-HIV drug zidovudine (ZDV) to treat HIV and reduce the chances of giving HIV to their babies. It recently has been shown that a combination of drugs may be more effective than ZDV alone. This study tests the effectiveness of combinations of ZDV, d4T, and 3TC.
NCT00000945
The purpose of this study is to evaluate the safety, tolerance, and overall effectiveness of cidovir to treat PML in AIDS patients. PML is an opportunistic infection (HIV-associated, due to weak immune system) caused by a virus that attacks the brain. Cidovir has been used effectively to treat cytomegalovirus (CMV) of the eye. Cidovir could be an effective treatment for PML as well.
NCT00005762
The purpose of this study is to measure the blood levels of amprenavir (APV) alone, APV combined with efavirenz (EFV), and APV/EFV combined with a third drug (nelfinavir \[NFV\], indinavir \[IDV\], ritonavir soft gel capsules \[RTV sgc\], or saquinavir soft gel capsules \[SQV sgc\]). Anti-HIV therapy with 3 or 4 drugs is currently the recommended approach for treating HIV infections. Doctors need to know the best dosages of certain drugs when they are given in combination. This study will measure the blood levels of APV alone, APV combined with EFV, and APV/EFV plus a second PI in healthy volunteers. It will study the safety and tolerance of these drugs.
NCT00038272
The purpose of this study is to evaluate the safety, efficacy, and side effects of beta-D-2,6-diaminopurine dioxolane (DAPD) compared to DAPD plus mycophenolate mofetil (MMF) when these drugs are added to the anti-HIV treatment regimens of people infected with HIV. Some studies have shown that DAPD and MMF can help fight HIV. However, neither DAPD nor MMF has been approved by the Food and Drug Administration for treating HIV infection. This study will help doctors decide if DAPD and MMF are good drugs for treating HIV.
NCT00000941
The purpose of this study is to find out whether taking protease inhibitors (anti-HIV drugs) together with lipid-lowering drugs (drugs which lower the amount of fat in the blood) has an effect on the level of drugs found in the blood compared to when these drugs are taken separately. The three protease inhibitors given in this study are ritonavir, saquinavir, and nelfinavir. The lipid-lowering drugs given are pravastatin, simvastatin, and atorvastatin. Anti-HIV drug therapy using protease inhibitors has become very common treatment for HIV-positive patients. Recently, however, serious side effects involving how the body uses fat have been reported in people taking protease inhibitors. Examples of these side effects are redistribution of body fat and development of diabetes. People taking protease inhibitors have been found to have higher levels of fat in their blood than is normal, which can cause heart problems. It is hoped that giving lipid-lowering drugs can help prevent serious heart problems. First, however, it is important to see what happens when protease inhibitors and lipid-lowering drugs are given together.
NCT00000887
The purpose of this study is to see if giving nelfinavir (NFV) plus zidovudine (ZDV) plus lamivudine (3TC) to HIV-positive pregnant women and their babies is safe. This study will also look at how long these drugs stay in the blood. ZDV has been given to mothers in the past to reduce the chances of passing HIV on to their babies. However, better treatments are needed to further reduce these chances and to better suit the treatment needs of mothers and their children. Taking a combination of anti-HIV drugs during pregnancy may be an answer.
NCT00000819
To determine the efficacy and safety of prednisone in patients with HIV-associated nephropathy. To determine the effects of prednisone on serum creatinine, urinary protein, and creatinine clearance. HIV-associated nephropathy is characterized by heavy proteinuria, rapidly progressive renal insufficiency, and distinct nephropathologic changes. The syndrome most often occurs in patients with advanced HIV disease. Little is known about the effects of corticosteroids on the progression of HIV disease. In light of the possible beneficial effects of corticosteroids on HIV-associated nephropathy, a controlled trial using prednisone is warranted.
NCT02273726
The primary objective of this study is to evaluate the efficacy and safety of roxadustat compared with active control (epoetin alfa) for the maintenance treatment of anemia in participants with ESRD on dialysis.
NCT01379222
The purpose of the study is to demonstrate the long term safety and effectiveness of the Endurant Stent Graft System for the endovascular treatment of infrarenal abdominal aortic aneurysms in a post-approval environment, through the endpoints established in this protocol. The clinical objective of the study is to evaluate the long term safety and effectiveness of the Endurant Stent Graft System assessed at 5 years through freedom from Aneurysm-Related Mortality (ARM).
NCT00001057
To determine the effects of zidovudine (AZT) alone and in combination with didanosine (ddI) on viral load in the lymphoid tissue and blood of antiretroviral-naive, HIV-infected patients with CD4 counts greater than or equal to 550 cells/mm3. Recent studies have shown that during the asymptomatic phase (clinical latency) of HIV infection, there is an extraordinarily large number of infected CD4+ lymphocytes and macrophages throughout the lymphoid system, both in latent and productive states. These findings support the belief that early intervention therapy with reverse transcriptase inhibitors could prolong the clinical latency period.
NCT00001061
To evaluate the effect of MSL 109, human monoclonal anti-cytomegalovirus (CMV) antibody, on time to progression of CMV retinitis. To determine the safety and pharmacokinetic profile of MS 109. To evaluate the relationship between pharmacokinetic measurements of MSL 109 and efficacy and virologic markers. Therapeutic agents currently available for CMV retinitis are limited by their inherent toxicities and short half-lives which require frequent intravenous dosing. Alternatively, MSL 109 has demonstrated safety and effectiveness in neutralizing CMV isolates at concentrations easily maintained in AIDS patients.
NCT00000857
The purpose of this study is to determine the tolerance and effectiveness of rhIL-12 in HIV-positive patients with CD4 cell counts less than 50 cells/mm3 versus 300-500 cells/mm3. This study will look at the ability of rhIL-12 to boost the immune system against HIV and HIV-associated bacterial infections in these patients. IL-12 is found naturally in the body and rhIL-12 is the commercially produced version. IL-12 may enhance anti-HIV immune system activity by increasing the number of cells that fight infection. IL-12 may also increase the body's ability to fight bacterial infections such as Mycobacterium avium complex (MAC).
NCT00000849
The purpose of this study is to determine the safety and maximum tolerated dose (the highest dose that can be given safely) of recombinant Interleukin-2 (rIL-2) in HIV-infected children. This study also evaluates the effect of rIL-2 on the immune system of these patients. IL-2 is a substance naturally produced by the body's white blood cells that plays an important role in helping the body fight infection. HIV-infected patients do not produce enough IL-2, and it is hoped that the use of rIL-2 may improve immune system function in these patients. First, it is necessary to determine the safety and effectiveness of this drug in HIV-infected children.
NCT00000839
To assess the pharmacokinetics, safety, and toxicity of intravenous and oral didanosine (ddI) administration in third trimester pregnant women who are HIV positive but are either intolerant or resistant to zidovudine (AZT). To collect data on infant toxicity following maternal treatment with ddI during the third trimester of pregnancy. AZT may not be the optimal antiretroviral agent for all pregnant women requiring therapy for HIV infection. Although ddI has been approved for use in HIV-infected adults and older children, the safety and pharmacokinetics of ddI in pregnant women has not yet been determined.
NCT01310413
This study will assess safety and immunogenicity of GSK Biologicals' H5N1 flu candidate vaccine GSK1557484A in children 6 months to \< 18 years of age.
NCT02688621
The investigators propose a randomized controlled trial to evaluate whether the addition of financial incentives to a high-quality, online behavioral weight loss intervention produces better weight losses than the online treatment alone.
