NCT00050895
With new strategies and drugs available, many different regimens exist for the treatment of HIV. The purpose of this study is to compare three different anti-HIV drug regimens as first-time treatments for HIV infection.
NCT00011011
Long-term control of HIV depends on improvement in an individual's immune system. The purpose of this study is to see if either stopping anti-HIV drugs for short periods of time and/or adding a vaccine to the anti-HIV drugs being taken will help to better control HIV infection. The study will test whether these treatment approaches are safe. The HIV vaccine in this study has been tested in people who did not have HIV infection and improved the way their immune system worked. This study will evaluate whether these same immune system changes happen in people with HIV, and, if such changes do occur, assess whether these changes help to improve control of HIV in these patients.
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.
NCT00001074
To determine the safety and tolerability of hydroxyurea at two doses alone and in combination with didanosine (ddI). To compare the short term antiviral effect of ddI monotherapy versus hydroxyurea plus ddI, as measured by plasma RNA levels at 8 weeks of therapy. \[AS PER AMENDMENT 10/1/97: Accrual to arms involving hydroxyurea alone has been closed.\] Current antiviral therapies for HIV-1 are limited by a few choices, and the lack of sustained clinical benefit from the drugs. The mechanisms that account for the lack of prolonged inhibition of viral replication by these agents are not fully understood. The activity of RT inhibitors might be potentiated by inhibiting host cellular enzymes essential for efficient HIV reverse transcription. Based on this information, comparisons of the antiviral effects of ddI monotherapy and hydroxyurea plus ddI, with the cellular enzyme ribonucleotide reductase as a potential target, should be done.
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.
NCT00033163
Control of hepatitis B virus (HBV) infection can be difficult in HIV infected people who have taken the antiviral lamivudine (3TC). These people may have HBV that has become resistant to 3TC. Adefovir dipivoxil (ADV) has shown promising anti-HBV activity in clinical trials; tenofovir disoproxil fumarate (TDF) is used to treat HIV and may also be effective against HBV. The purpose of this study is to find out if adding ADV or TDF to a highly active antiretroviral therapy (HAART) regimen that includes 3TC has an effect on HBV infection in patients coinfected with HIV and HBV. The tolerability and safety of these drugs will be examined.
NCT00001136
The purpose of this study is to see if it is safe to give an HIV vaccine (vCP205) to volunteers who received an HIV vaccine at least 2 years ago, and to study how the immune system responds to this vaccine. Vaccines are given to people to try to resist infection or prevent disease. There are a number of different HIV vaccines that are currently being tested. The vaccines that seem to be the most promising are canarypox vaccines, known as ALVAC vaccines; the vaccine tested in this study is ALVAC-HIV vCP205. This study will look at the safety of the vaccine and how the immune system responds to it.
NCT00006145
Cytomegalovirus (CMV) infection is a common opportunistic infection (OI) in HIV patients. The purpose of this study is to find out whether valganciclovir, an antiviral approved by the FDA for the treatment of CMV in the eye, is safe and effective in preventing CMV organ damage in people with HIV.
NCT00028366
Ritonavir (RTV) is a protease inhibitor (PI) commonly used to increase drug levels of other PIs in HIV drug treatment. The purpose of this study is to compare a combination of drugs which includes RTV and 2 protease inhibitors (PIs) with 2 combinations that include RTV and another PI. This study also will compare the effectiveness, safety, tolerability, and drug levels in the blood of these anti-HIV drug combinations.
NCT00001104
Study A: To determine whether treatment with zidovudine (ZDV) will delay or change the disease process in hemophilic patients who have HIV infection with no symptoms. The major clinical question is whether patients who receive chronic ZDV therapy will have a delay in the development of AIDS or AIDS-related complex (ARC). The pharmacokinetics (blood levels) of ZDV in hemophilic patients will also be studied. Study B: To determine if ZDV therapy changes the risk of a hemophiliac transmitting HIV to his wife or other female sexual partner. To determine the effectiveness of counseling and education on the behaviors of the wives that place them at risk for HIV infection. To determine if antibodies to HIV either appear or disappear from the blood of any of the wives during the study. Study A: Individuals who are infected with HIV can benefit from therapy with an effective anti-AIDS virus agent. ZDV is a potent inhibitor of HIV in vitro (test tube) and is safe in humans at the dose planned. It may be effective in preventing the development of AIDS or ARC in hemophiliacs who have the HIV antibody in their blood. The pharmacokinetic studies are especially important because the high prevalence of hepatic disease in this population may affect the metabolism and blood levels of ZDV. Study B: HIV is transmitted by sexual contact, and wives of infected hemophilic patients have become infected during long-term sexual relationships. Transmission of the virus does not occur during casual family contact. This study will aid in determining if therapy influences the transmission of HIV, because the wives of hemophiliacs generally have no risk for HIV infection other than sexual contact with their spouse.
NCT00006144
The purpose of this study is to better understand the relationship between age and HIV disease progression. This study will explore the possible relationship between age and HIV disease progression. Older age is an important risk factor for faster disease development, but older people may respond better to combination drug therapy. This relationship needs to be understood better.
NCT00017719
The best anti-HIV treatment regimen for pregnant women is not known. Protease inhibitors (PIs) are often used, but they have side effects that may be harmful for pregnant women. It is not known if treatment regimens that do not include PIs are as effective in pregnant women as those that include PIs. This trial will compare two anti-HIV treatment plans, one with and one without PIs, in women who start HIV treatment during pregnancy. The study will evaluate the effects of the anti-HIV drugs on the developing infant and prevention of mother-to-child HIV transmission during pregnancy.
NCT00001030
To compare the efficacy and safety of clarithromycin alone versus rifabutin alone versus the two drugs in combination for the prevention or delay of Mycobacterium avium Complex (MAC) bacteremia or disseminated MAC disease. To compare other parameters such as survival, toxicity, and quality of life among the three treatment arms. To obtain information on the incidence and clinical grade of targeted gynecologic conditions. Persons with advanced stages of HIV are considered to be at particular risk for developing disseminated MAC disease. The development of an effective regimen for the prevention of disseminated MAC disease may be of substantial benefit in altering the morbidity and possibly the mortality associated with this disease and its treatment.
NCT00063804
Most currently approved anti-HIV drugs work by stopping the replication of HIV after it has entered cells. AMD070 (also known as AMD11070) is designed to block HIV from entering cells and may be effective in treating patients who have developed resistance to or are unable to take other anti-HIV drugs. This study will evaluate the safety of different doses of AMD070 along with AMD070 boosted with ritonavir (RTV) in HIV uninfected men.
NCT00865969
The purpose of this study is to assess efficacy and safety of belinostat in participants with relapsed or refractory peripheral T-cell lymphoma (PTCL), who failed at least one prior systemic therapy.
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.
NCT00000929
The purpose of this study is to see if it is safe and acceptable for homosexual male couples, where both partners have the same HIV status, to use Advantage 24 during anal intercourse. Advantage 24 is a spermicide (a chemical that kills sperm). Much research and development is being done with chemicals that can be controlled by the receptive partner to prevent the spread of HIV and other sexually transmitted diseases (STDs). Advantage 24 currently is used in the vagina as a form of birth control. The safety of Advantage 24 is particularly important for HIV-positive men because they have a greater chance of serious reaction to Advantage 24 due to other HIV-related conditions.
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.
NCT03170271
The purpose of this study is to investigate the effect of benralizumab on the rate of asthma exacerbations, patient reported quality of life and lung function during the 24-week treatment in patients with uncontrolled, severe asthma with an eosinophilic phenotype. A subset of patients will be assessed for their ongoing chronic rhinosinusitis with nasal polyps. The study design has been updated to include a 56-week open label ANDHI in Practice (ANDHI IP) sub study upon the completion of the 24-week double-blind period of the ANDHI study.
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.
