NCT00992017
Both pregnant women and people infected with HIV are at increased risk of viral infection, including influenza infection. Pregnant women infected with HIV may be at particular risk of infection from the new H1N1 influenza virus. This study tested the safety and immunogenicity of an H1N1 influenza vaccine in pregnant women infected with HIV.
NCT02269163
Phase 3 multicenter, open-label study of safety, tolerability, efficacy, and pharmacokinetics (PK) of ProMetic's Immune Globulin Intravenous (Human) 10%, the investigational medicinal product \[IMP\]), in Adults and Children with Primary Immunodeficiency Diseases (PIDD).
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.
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.
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.
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.
NCT00001011
To determine the safety and usefulness of zidovudine (AZT) for the treatment of patients with early symptomatic HIV infection or early AIDS related complex (ARC). The ability of AZT to suppress HIV, to improve body defenses, and to prevent the occurrence or development of AIDS or advanced ARC is being evaluated. In one human study, patients with AIDS or advanced ARC who received AZT had fewer life-threatening infections, improved in weight and performance, and lived longer than patients who received a placebo (inactive medication). Further studies are needed because toxic effects associated with the use of AZT were noted and the long-term effectiveness and toxicity of AZT are still unknown. It is also unknown if AZT will benefit patients with less severe HIV infections such as early ARC or PGL.
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.
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.
NCT00001029
To compare the efficacy, safety and tolerance, and other clinical and immunologic effects of zidovudine (AZT) plus zalcitabine (dideoxycytidine; ddC), AZT plus didanosine (ddI), and AZT alternating monthly with ddI as measured by differences in survival among HIV-infected persons who have received 6 or more months of nucleoside monotherapy and have a CD4 count greater than or equal to 50 cells/mm3. Combining two nucleoside drugs has the theoretical advantage of optimal protection against the evolution of resistant strains of HIV. However, one major problem with combination nucleoside therapy in patients with advanced disease is the increased toxicity resulting from such therapy. One approach to minimize toxicity while perhaps retaining some of the benefits of combination therapy is to alternate the two drugs.
NCT03209362
The objective of the study is to evaluate the efficacy and safety of intra-articular injections of SI-613 compared with placebo for knee OA.
NCT00000742
Part I: To determine the pharmacokinetic dose for atevirdine mesylate ( U-87201E ) when used in combination with zidovudine ( AZT ). To determine the pharmacokinetic profiles of U-87201E and AZT over a 12-week period. Part II: To determine whether or not decreased viral susceptibility to U-87201E develops when the drug is administered concomitantly with AZT for 12 weeks. Part III: To evaluate the pharmacokinetic effects of ddI/AZT/U-87201E therapy and to assess changes in viral susceptibility to U-87201E. Interest exists in the development of antiretroviral agents that possess different mechanisms of action from nucleoside analogs such as AZT. U-87201E is a non-nucleoside reverse transcriptase (RT) inhibitor that has demonstrated activity against HIV-1; however, an emerging characteristic of non-nucleoside RT inhibitors is the development of rapid resistance to HIV isolates. Whether this resistance can be prevented in the presence of nucleoside analogs such as AZT and ddI has yet to be determined.
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.
NCT00001084
To compare the proportion of patients who sustain suppression of plasma HIV RNA to undetectable levels \[AS PER AMENDMENT 09/19/97: below 200 copies/mL by Roche UltraSensitive assay\] among the 3 regimens during the maintenance phase. The objective of antiretroviral therapy is to reduce HIV replication, preserve immunologic function and delay the development of HIV-related complications. In patients administered potent antiretroviral regimens, HIV RNA levels are reduced below 500 copies/ml of plasma and below the level of detection of commercially available assays. This protocol attempts to learn if a less intensive regimen can successfully sustain viral suppression after induction with a triple-drug regimen. The study also addresses whether HIV can be eradicated in patients following prolonged treatment with induction and maintenance regimens.
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.
NCT00001095
To determine the proportion of patients treated with amprenavir, zidovudine (ZDV), stavudine (D4T) and lamivudine (3TC) whose HIV-1 RNA level remains below the level of detection during 96 weeks of therapy. To determine the proportion of patients treated with indinavir (IDV), nevirapine (NVP), 3TC, and d4T whose HIV-1 RNA level decreases and then remains below the level of detection, during the 96-week therapy period. To determine the viral effects, safety, tolerability, and pharmacokinetics of amprenavir in combination with zidovudine, stavudine, and lamivudine. \[AS PER AMENDMENT 2/27/98: To determine the proportion of patients with undetectable plasma HIV RNA, by treatment and baseline RNA cohort (either detectable or undetectable). To determine the durability of these regimens by estimating the distribution of time to loss of virologic suppression (or equivalently, time to virologic failure), by treatment and baseline RNA cohort.\] This study allows patients who have successfully participated in ACTG 347 or other trials involving amprenavir to continue treatment with amprenavir, ZDV, d4T, and 3TC. Additionally, this study provides patients whose HIV-1 RNA was not reduced to undetectable levels or who had a significant increase in plasma levels ("treatment failures") the opportunity to change to a potentially more active regimen that includes indinavir, nevirapine, lamivudine, and stavudine.
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.
NCT00991289
Infection with hepatitis C virus (HCV) can cause liver scarring, or cirrhosis, and this usually occurs more rapidly among people infected with both HCV and human immunodeficiency virus (HIV). People infected with both HCV and HIV have poor response to the current HCV treatments. This phase II pilot study evaluated whether adding a new HCV medication improves response to the current standard HCV treatment with pegylated interferon and ribavirin in people with both HCV and HIV.
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.
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.
