NCT00075829
The study is designed as a Phase III, multi-center trial of tandem autologous transplants versus the strategy of autologous followed by Human Leukocyte Antigen (HLA)-matched sibling non-myeloablative allogeneic transplant. Study subjects will be biologically assigned to the appropriate arm depending on the availability of an HLA-matched sibling. There is a nested randomized phase III trial of observation versus maintenance therapy following the second autologous transplant for patients on the tandem autologous transplant arm.
NCT04567745
This study aims to provide clinical validation of EyeQuant, a fully automated retinal image analysis system for computation of vascular biomarkers indicative of cognitive disorders, using retinal fundus photographs collected from patients with mild cognitive impairment, Alzheimer's disease, and vascular dementia.
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.
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.
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.
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.
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.
NCT00008463
The purpose of this study is to see if treatment with PEG-interferon-alfa-2a (PEG-IFN) plus ribavirin is a more effective treatment for hepatitis C virus (HCV) than interferon-alfa-2a (IFN) plus ribavirin for patients infected with both HCV and HIV. The study will also compare the 2 regimens to see which has fewer side effects. HCV infection is common in patients infected with HIV. Patients infected with both HIV and HCV viruses seem to have more severe hepatitis C. A combination of IFN and ribavirin has been shown to lessen the severity of HCV. PEG-IFN is a modified form of IFN that stays in the blood longer, which means that patients would not have to take the treatment as often. This study will compare the safety and effectiveness of PEG-IFN to IFN when each is combined with ribavirin.
NCT00201240
This study is a single arm Phase II, multicenter trial. It is designed to determine whether the anticipated endpoints for a T cell depleted transplant arm of a planned prospective randomized trial comparing T cell depleted and unmodified hematopoietic allografts are likely to be achieved in a multicenter study conducted by the Blood and Marrow Transplant Clinical Trials Network (BMT CTN or Network). The study population is patients with acute myeloid leukemia (AML) in first or second morphologic complete remission. The enrollment is 45 patients. Based on published results of unmodified transplants from HLA-matched siblings applied to patients with AML in first or second morphologic complete remission, a significant improvement in results with a graft modified as specified in this protocol would be expected if disease-free survival (DFS) at 6 months was greater than 75%, the true incidence of transplant-related mortality at 1 year was less than 30%, and the DFS rate at 2 years was greater 70% for patients transplanted in first remission and less than 60% for patients transplanted in second remission. Additional secondary endpoints include the following: graft failure rate and incidences of acute grade II-IV and chronic graft-versus-host disease (GVHD). Additionally, the trial will have target specific doses of CD34+ progenitors and CD3+ T cells to be obtained following fractionation with the CliniMACS system. Based on the results of this trial, a Phase III trial comparing T cell depleted peripheral blood stem cell transplants (PBSCT) with unmanipulated bone marrow or unmanipulated PBSCT will be designed.
NCT00001125
The purpose of this study is to see if the varicella-zoster virus (VZV) vaccine will be safe and if it can help prevent shingles in HIV-infected children who have already had chickenpox. VZV is the virus that causes chickenpox. If this virus is reactivated in the body, it can also cause shingles. Shingles is common in children with HIV who have had chickenpox, although it is usually not life-threatening. The VZV vaccine used in this study may be able to prevent HIV-positive children who have had chickenpox from developing shingles.
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.
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.
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.
NCT00096694
Oral contraceptives (OCs) are not a good option for some HIV infected women because of the potential for drug interactions between OCs and anti-HIV drugs; additionally, OCs may increase the risk of transmitting HIV to sexual partners. Levonorgestrel is commonly prescribed as part of a combination OC. An intrauterine device (IUD) is a device inserted in a woman's uterus to prevent pregnancy. The purpose of this study is to determine the effect of a levonorgestrel-releasing IUD on the amount of HIV present in an HIV infected woman's cervix after 4 weeks of IUD use. Study hypothesis: There will be no increase in genital tract HIV RNA and DNA after placement of the levonorgestrel IUD.
NCT00001009
To determine the effectiveness and safety of dextran sulfate (DS) as a treatment for patients with AIDS, AIDS related complex (ARC), or asymptomatic HIV infection with or without persistent generalized lymphadenopathy (PGL), and to determine antiviral activity at different doses of DS. Although zidovudine (AZT) has shown promise in prolonging life in patients with AIDS and severe ARC, it has significant blood toxicities. It would be beneficial to combine AZT with another antiviral agent that does not have the same toxicity. DS might be a suitable drug since it has shown antiviral activity against HIV in the laboratory, and in preliminary studies it has shown little toxicity. Also, the combination of DS with AZT has been shown to be more effective than either alone.
NCT00001133
In this study, the protease inhibitors indinavir (IDV) and ritonavir (RTV) will be studied in patients who have high levels of virus while taking other protease inhibitors. The purpose of this study is to see how the body takes in, distributes, and gets rid of IDV and RTV. This study will also look at any side effects that IDV or RTV causes. IDV is an effective anti-HIV drug, but it can be difficult for patients to take. For IDV to work against HIV, it must be taken 3 times a day at a high dose and with a certain diet. Doctors believe IDV may be easier to take if it is given with RTV. Patients who take IDV and RTV together may be able to take IDV only twice a day and at a lower dose. This study will gather information about the safety and side effects of using IDV and RTV together.
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.
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.
NCT00421174
The study is designed as a Phase III, multi-center randomized, double-blind, placebo-controlled trial investigating the use of etanercept for the treatment of acute, non-infectious pulmonary dysfunction (IPS) occurring after allogeneic hematopoietic cell transplantation (HCT).
NCT00001116
The purpose of this study is to determine if TNFR:Fc (a molecule that attaches to TNF) can lower the amount of IL-6 in HIV-positive patients. This study will also examine the effect of TNFR:Fc on TNF-alpha. IL-6 and TNF-alpha are 2 substances produced by the immune system that may increase the rate of HIV replication. IL-6 and TNF-alpha are produced naturally by the body. High levels of TNF-alpha lead to increased IL-6 production and increased HIV replication, therefore helping the virus infect the body. HIV-positive patients who receive IL-2 (interleukin-2, a protein that helps the immune system fight infection) tend to have higher levels of IL-6 and TNF-alpha than patients not receiving IL-2. These increased levels may contribute to some of the flu-like symptoms related to IL-2 administration. TNFR:Fc can neutralize TNF-alpha to decrease the action of TNF-alpha and, in turn, decrease the amount of IL-6 in the body. TNFR:Fc may, therefore, have a role in the treatment of HIV disease or in relieving some of the symptoms related to IL-2 administration.
