NCT01231516
ING111762 is a 48 week, randomized, double-blind, active-controlled, multicenter, parallel group, non-inferiority study. The study will be conducted in at least 688 HIV-1 infected antiretroviral experienced, integrase-naïve subjects. Subjects will be randomized 1:1 to receive GSK1349572 50 mg once daily or raltegravir (RAL) 400 mg twice daily, each added to an investigator selected background regimen consisting of at least one fully active agent plus no more than one second single agent which may or may not be active. Antiviral activity, safety, pharmacokinetics (PK), and development of viral resistance will be evaluated.
NCT02519777
People infected with HIV often have cognitive dysfunction even if they are on antiretroviral therapy (ART) and have undetectable viral loads. The study evaluated if the addition of maraviroc (MVC) and dolutegravir (DTG) (which are two antiretroviral \[ARV\] medications) to participants' existing ART regimens improved participants' neurocognitive performance.
NCT00339040
The purpose of this study is to determine the safety of and immune response to a new human papillomavirus (HPV) vaccine in HIV (Human immunodeficiency virus) infected children between the ages of 7 and 12 years.
NCT02411539
The purpose of this study was to evaluate the safety, tolerability, and effect of an experimental human monoclonal antibody (mAb), VRC-HIVMAB060-00-AB (VRC01), in adults infected with HIV who were receiving antiretroviral therapy (ART).
NCT00766597
Complications with current HIV antiretroviral therapy have left many children and adolescents with limited therapeutic options due to drug resistance. The purpose of this study is to test the effectiveness and safety of Vicriviroc (VCV), an HIV entry inhibitor and CCR5 co-receptor antagonist.
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.
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.
NCT00000838
To evaluate the efficacy, safety, and pharmacokinetics of lamivudine (3TC) combined with zidovudine (AZT), stavudine (d4T), or didanosine (ddI) in comparison with d4T or ddI monotherapy in HIV-infected patients with no prior nucleoside therapy. 3TC may be uniquely effective in combination with AZT due to the interaction of AZT and 3TC resistance mutations. One explanation is that the M184V mutation, which confers resistance to 3TC, suppresses AZT resistance. This benefit of 3TC may not extend to combination therapy with other nucleoside analogs.
NCT00000831
To elucidate the relationship between virologic risk factors and immunologic and clinical progression in patients receiving monotherapy in protocol ACTG 175, and to compare new treatment regimens with combinations of reverse transcriptase inhibitors in long-term recipients of monotherapy. Specifically, to determine, in patients who have been taking zidovudine (AZT) alone for a long time, whether it is beneficial to add lamivudine (3TC) to AZT or to switch to d4T alone, and also to determine, in patients who have been taking didanosine (ddI) alone for a long time, whether it is beneficial to add AZT or AZT/3TC to ddI. Characteristics of virus replication, pathogenicity, and resistance are thought to determine the durability of virologic and clinical response to nucleoside reverse transcriptase inhibitors. Previous results of ACTG 175 suggest that either a switch to ddI or addition of ddI in patients receiving AZT results in better clinical, virologic, and CD4 cell response compared to continuation of AZT alone.
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.
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.
NCT00000802
To compare the efficacy and safety of dapsone versus atovaquone in preventing or delaying the onset of histologically proven or probable Pneumocystis carinii pneumonia in HIV-infected patients with CD4 counts \<= 200 cells/mm3 or \<= 15 percent of the total lymphocyte count who are intolerant to trimethoprim and/or sulfonamides. Trimethoprim/sulfamethoxazole (TMP/SMX), which is effective for secondary PCP prophylaxis, is associated with allergic manifestations and side effects that limit its use. Patients who are intolerant of TMP/SMX require an effective alternative. Dapsone and atovaquone have both shown promise as PCP prophylactic agents.
NCT00001063
To compare the effect of stavudine (d4T) alone or with zidovudine (AZT) versus didanosine (ddI) alone or with AZT on CD4 counts, HIV RNA levels, and viral load in HIV-infected patients \[AS PER AMENDMENT 3/21/97: To compare the effects of d4T alone versus ddI alone versus AZT plus ddI\]. To compare the safety of d4T/AZT. AS PER AMENDMENT 3/21/97: To evaluate the pharmacokinetic interactions of AZT and d4T both at an extracellular and intracellular level. Although AZT and ddI can delay the advancement of HIV disease, the benefit of either of these drugs has proven to be only temporary. d4T, a new nucleoside analog with a favorable toxicity profile and demonstrated activity against HIV, offers an additional therapeutic option. It is reasonably assumed that the benefit of an antiretroviral agent in terms of delaying clinical disease progression is directly related to its ability to achieve and sustain viral suppression; thus, this study measures effects on viral load and CD4 count.
NCT00006604
The purpose of this study was to find a safe and tolerable dose of the protease inhibitor (PI) atazanavir (ATV), with or without a low-dose boost of the PI ritonavir (RTV), when taken with other anti-HIV drugs in HIV infected infants, children, and adolescents. Advancements in anti-HIV drugs for HIV infected children and adolescents have been hard to make, in part because these patients often do not take the drugs as prescribed. ATV may be a better option because it is available in the form of powder which children and adolescents may be more willing to take regularly. Using a low dose of RTV as a boosting agent for ATV may also increase the chances of virologic response of highly active antiretroviral treatment (HAART)-experienced patients. This study aimed to find safe and tolerable doses of ATV with or without low-dose RTV boost in infants, children, and adolescents. For this study, participants were enrolled in the United States and South Africa.
NCT00000808
To determine the bioavailability, pharmacokinetics, and short-term safety and tolerance of nevirapine in HIV-1 infected pregnant women and their newborns when nevirapine is given to the mother during active labor, and when their neonates are dosed during the first week of life. To determine the short-term safety profile of mothers receiving zidovudine (AZT) who received nevirapine during active labor, and their neonates who received no dose, a single dose, or multiple doses of nevirapine and who are receiving AZT during the first 6 weeks of life. Treatment of HIV-1 infected pregnant women during active labor may result in therapeutic levels of nevirapine in the neonate at the time of exposure to HIV-1 during parturition, decreasing the neonate's risk of infection.
NCT02833844
The study is divided into 2 parts. The first part of the study will be double-blinded and will last for 24 weeks. During this time, participants will be randomized in a ratio of 2:1 to receive either evolocumab once monthly (QM) or placebo QM. The second part of the study is a 24-week open label extension period. During this time all participants will receive evolocumab QM. The clinical hypothesis is that subcutaneous evolocumab QM will be well tolerated and will result in greater reduction of low density lipoprotein cholesterol (LDL-C), defined as percent change from baseline at Week 24, compared with placebo QM in human immunodeficiency virus (HIV)-positive participants with hyperlipidemia or mixed dyslipidemia.
NCT00001071
To determine the safety of stem cell harvesting after administration of filgrastim ( G-CSF ) to mobilize bone marrow stem cells into the peripheral blood in patients at various stages of HIV-1 infection as well as in HIV-negative volunteers. To determine the surface phenotypic and functional characteristics as well as the viral load in the stem cells obtained following this procedure.
NCT03671239
MTN-035 is a multi-site, randomized-sequence, three-period, open label crossover study that will enroll approximately 210 participants randomized (1:1:1:1:1:1) to one of six sequences of rectal microbicide placebo product application.
NCT01632995
This study will assess the uptake, acceptability, safety, and feasibility of HIV pre-exposure prophylaxis (PrEP), consisting of a once-daily fixed-dose combination tablet of emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF), administered at sexually transmitted disease (STD) clinics and a community health center in the United States.
NCT00001031
To evaluate the safety and immunogenicity of SF-2 rgp120 vaccine in MF59 versus MN rgp120 vaccine in alum in volunteers who are seronegative for HIV-1. AS PER AMENDMENT 07/02/97: To determine the ability of immunization with MN rgp120/HIV-1 in combination with alum or SF-2 rgp120 in combination with MF59 to induce an HIV-1 envelope-specific delayed-type hypersensitivity (DTH) response in volunteers who receive rsgp120/MN skin testing. The amino acid sequence of HIV-1 gp120 can vary as much as 40 percent from isolate to isolate. Thus, the identification of an immunogen that can elicit broadly neutralizing antibodies to HIV-1 is a major challenge in AIDS vaccine development. Two candidate vaccines, recombinant envelope subunit proteins from the SF-2 and MN isolates of HIV-1, have shown immunogenicity and good tolerance in healthy immunocompetent adults. This study will expand testing into a larger population base, particularly targeting individuals at high risk for HIV infection.
