NCT00537394
The goal of anti-HIV therapy is to prevent HIV from replicating. Long-term control of HIV requires at least two anti-HIV drugs that are active against the virus. Drug resistance is a problem for many treatment-experienced, HIV-infected people. The purpose of this study was to determine the benefit of adding a nucleoside reverse transcriptase inhibitor (NRTI) to a new anti-HIV drug regimen for the suppression of HIV.
NCT00376935
Palifermin is a modified version of a naturally occurring human growth factor that is currently approved by the FDA to treat blood cancers. The purpose of this study is to determine whether palifermin can increase CD4 counts in treatment-experienced HIV infected adults.
NCT00001004
To study the tolerance and toxicity of the combination of tumor necrosis factor (TNF) and interferon gamma (IFN-G) or as single agent TNF or IFN-G in HIV infected patients. To selectively monitor the immune system of AIDS related complex (ARC) patients who receive either combination therapy or TNF or IFN-G alone. To obtain information on the effectiveness of combination therapy or TNF or IFN-G alone against HIV in ARC patients. Recombinant TNF and recombinant IFN-G have been shown to be effective against the virus which causes AIDS and ARC in some laboratory studies, but may increase virus replication in other laboratory studies. Previous studies in humans showed no increase in virus cultures and some decrease in measurements of virus. Extensive preclinical data show that TNF and IFN-G are more effective together than separately in laboratory and animal studies. As single agents, both TNF and IFN-G have modest effect against HIV. Studies have demonstrated that TNF and IFN-G, in combination, can not only inhibit HIV infection of previously uninfected cells, but also can selectively induce the destruction of acutely infected target cells.
NCT00604175
Human papillomavirus (HPV) is the most common sexually transmitted disease in the world. HPV infection can cause genital warts and certain cervical problems, including cervical cancer. HPV infection may be more severe and harder to treat in HIV-infected people. The purpose of this study was to determine whether the quadrivalent HPV vaccine is safe, tolerable, and effective in producing antibodies to HPV in HIV-infected women.
NCT00000991
To evaluate and compare 3 anti-pneumocystis regimens plus zidovudine (AZT) in persons with HIV infection and T4 cell count less than 200 cells/mm3. All persons completing at least 8 weeks of therapy on 081 will be offered the opportunity to participate in the nested study (ACTG 981) of systemic antifungal therapy (fluconazole) versus local therapy (Clotrimazole) for the prevention of serious fungal disease. Persons with HIV disease who are receiving AZT are at risk for PCP, toxoplasmosis, bacterial pneumonia, and other serious infections. It is therefore important to find drugs that can be given along with AZT to control these infections. Aerosolized pentamidine (PEN) has been shown to be useful in preventing PCP and is expected to lower the 2-year risk of PCP. Both sulfamethoxazole/trimethoprim (SMX/TMP) and dapsone probably also provide effective preventive treatment against PCP, and both may be useful in preventing toxoplasmosis and extrapulmonary pneumocystosis.
NCT00000702
To test whether zidovudine (AZT) is useful as a treatment for the neurologic syndrome called AIDS dementia complex. To determine how long AZT takes to reach cerebral spinal fluid (CSF), how long, and at what concentration it is found there. HIV infection can result in impairment in the function of the brain and spinal cord, leading to disturbances in the ability to think clearly and in strength and coordination. This disorder, which has been called the AIDS dementia complex, may be due to a direct effect of HIV on the nervous system. It is known that AZT does get into the brain to some extent, where it may reduce growth of HIV. It is hoped that AZT will stabilize or improve the symptoms of the AIDS dementia complex.
NCT00485264
Integrase is 1 of 3 HIV (Human Immunodeficiency Virus)-1 enzymes required for viral replication. Raltegravir is a drug that prevents integrase from working properly. This drug has been tested for safety and efficacy in adults, but this is the first study to examine raltegravir in children and adolescents. The purpose of this study was to determine the appropriate dose for raltegravir across the pediatric age range from 4 weeks to 18 years of age, by acquiring short and long term safety data, intensive and population pharmacokinetic (PK) data, and efficacy experience with raltegravir in HIV-infected children and adolescents.
NCT00000651
To evaluate the safety of zalcitabine (dideoxycytidine; ddC) alone and in combination with zidovudine (AZT) versus AZT alone when administered to asymptomatic patients with a CD4 count = or \< 200 cells/mm3 and symptomatic patients with a CD4 count = or \< 300 cells/mm3. To compare the effectiveness of ddC alone and in combination with AZT versus AZT alone. ddC has been shown to demonstrate an antiviral effect. AZT has been shown to significantly decrease mortality and reduce the frequency of opportunistic infections in patients with AIDS or advanced ARC. After 1 year of AZT therapy, the effectiveness tends to diminish and patients progress with more opportunistic infections and higher mortality rates. Because of the demonstrated antiviral activity, absence of hematologic toxicity, and lack of cross tolerance in laboratory studies of ddC, a study to investigate the long-term effectiveness of ddC in patients with HIV infection who have received AZT therapy is warranted.
NCT03337542
This study is enrolling participants by invitation only. This is an open-label, safety extension study for subjects who participated in the ARC007 study.
NCT02806947
The study is a Phase II randomized, open label, multicenter trial designed to identify whether sirolimus is a potential alternative to prednisone as an up-front treatment for patients with standard-risk acute GVHD defined according to clinical and biomarker-based risk stratification. This trial incorporates both a novel up front GVHD therapy (sirolimus) as well as a novel BMT CTN developed acute GVHD biomarker test.
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.
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.
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.
NCT00082498
New treatment options are critical for treatment-experienced HIV infected patients with drug resistance. HIV entry inhibitors have been shown effective in patients with resistance to other anti-HIV drugs. This study will test the safety and effectiveness of three different doses of vicriviroc (formerly known as Schering D, SCH-D, or SCH 417690) in HIV infected patients.
NCT00125099
The purpose of this study is to evaluate whether the HIV vaccine VRC-HIVDNA009-00-VP will be safe in individuals who started antiretroviral therapy during acute HIV-1 infection. The study will also test whether the vaccine can increase the immune system function in these participants.
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).
NCT00000946
The purpose of this study is to test three experimental HIV vaccines. This study will look at whether it is safe to give these vaccines together and how the immune system responds to the vaccines. There are a number of studies being performed to test HIV vaccines. The vaccines that seem to be the most promising are canarypox vaccines, known as ALVAC vaccines. The three experimental HIV vaccines used in this study are called ALVAC-HIV vCP205, HIV-1 SF-2 p24, and HIV-1 SF-2 rgp120. The HIV-1 SF-2 p24 and HIV-1 SF-2 rgp120 vaccines are mixed with an adjuvant, which is a substance that increases immune response.
NCT00000793
To assess the efficacy, safety, and tolerability of amitriptyline hydrochloride versus mexiletine hydrochloride in reducing pain intensity in patients with HIV-related painful peripheral neuropathy. No large-scale controlled clinical trials of symptomatic therapy for painful HIV-related neuropathy have been attempted. Both amitriptyline and mexiletine have been useful in the management of painful neuropathies; however, both are associated with certain toxicities. In this comparative study of amitriptyline and mexiletine, benztropine mesylate also will be included as an active placebo to mimic the side effects of the study drugs.
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.
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.
