NCT00000172
Galantamine is an experimental drug being evaluated in the United States for the treatment of Alzheimer's disease. Results from previous clinical trials suggest that galantamine may improve cognitive performance in individuals with Alzheimer's disease. It is not a cure for Alzheimer's disease. Nerve cells in the brain responsible for memory and cognitive function communicate using a chemical called acetylcholine. Research has shown that deterioration of cells that produce acetylcholine in the brain affects thought processes. Galantamine is thought to work in two ways to increase the amount of acetylcholine available in the brain. It inhibits an enzyme that breaks down acetylcholine and it also stimulates the nicotinic receptors in the brain to release more acetylcholine.
NCT00032279
The purpose of this phase II study is to evaluate an investigational monoclonal antibody for the treatment of glucocorticoid-refractory Graft Versus Host Disease (GVHD). Patients diagnosed with GVHD who have not responded satisfactorily to, or are intolerant of, treatment with standard agents will be considered for entry. Patients will be allowed to continue on their other immunosuppressive drugs at stable doses during the trial. The research is being conducted at up to 20 clinical research sites in the US.
NCT00002378
To determine the proportion of patients whose plasma HIV-1 RNA level falls below the level of detection (\< 400 copies/ml) at week 24 of study therapy. To determine the absolute change in plasma HIV-1 RNA during the 24 weeks of study treatment. To collect safety data on the treatment regimens. AS PER AMENDMENT 12/12/97: To compare the virologic response of Fortovase (FTV) (Saquinavir) Soft Gel Capsule (SGC) tid plus nucleoside reverse transcriptase inhibitors (NRTIs) versus FTV bid plus NRTIs. Further, to compare the virologic response of FTV tid plus NRTIs versus FTV bid plus Nelfinavir bid plus a NRTI with respect to: the percentage of patients whose plasma HIV-1 RNA level falls below the Amplicor assay level of detection (\< 400 copies/ml) at week 24 and week 48.
NCT00002228
The purpose of this study is to see if it is safe and effective to give T-20 to HIV-positive adults. T-20 is an anti-HIV drug.
NCT00007436
The purpose of this study is to evaluate the safety of tenofovir disoproxil fumarate (tenofovir DF) in combination with other anti-HIV drugs in patients who have participated in other tenofovir DF studies (GS-98-902 or GS-99-907), are able to tolerate the drug at different doses, and may benefit from having tenofovir DF treatment.
NCT00043758
The purpose of this study is to study the effects of tolvaptan on the size and function of the left heart chamber (ventricle) in patients with congestive heart failure (CHF)
NCT00002322
To determine the tolerance and antiviral response of two different doses of atevirdine mesylate (U-87201E) in symptomatic HIV-positive patients with CD4 counts of 50-350 cells/mm3, who also take zidovudine (AZT).
NCT00002441
The purpose of this study is to see if an HIV vaccine, AIDSVAX B/B, can protect adults who are at risk from becoming infected with HIV. Patients who become infected despite immunization will be studied to see if receiving the vaccine before becoming infected will help keep HIV levels (viral load) low.
NCT00022932
The purpose of this study is to determine the safety and effectiveness of using Iodine-131 Anti-B1 Antibody for the treatment of patients with large B-cell non-Hodgkin's lymphoma (NHL) who have achieved a response following 6-8 cycles of CHOP therapy.
NCT00002257
To compare the time to progression of CMV retinitis between oral ganciclovir and IV ganciclovir during 20 weeks of maintenance treatment. To compare the safety and tolerance of oral ganciclovir with IV ganciclovir therapy during 20 weeks of maintenance treatment. To describe the safety and tolerance of oral ganciclovir treatment when given concurrently with anti-retroviral treatment, e.g. zidovudine or ddI. To describe the survival of people with AIDS and CMV retinitis.
NCT00005012
The purpose of this study is to see if it is effective to give PEG-Intron (PEG-IFN) to HIV-infected patients who are not doing well with their current anti-HIV drug combination (HAART).
NCT00009061
The purpose of this study is to compare virus response to GW433908/ritonavir (RTV) to viral response to nelfinavir (NFV) when used with abacavir (ABC)/lamivudine (3TC) in patients that have not taken antiretroviral (ART) drugs.
NCT00000828
To identify patterns of zidovudine ( AZT ) susceptibility among mother/infant pairs with perinatal HIV transmission. Most HIV-infected infants acquire their disease via perinatal transmission. Since transmission of HIV-resistant strains to infants could alter the course of disease and response to currently recommended treatment, a study to assess the patterns of AZT susceptibility among mother/infant pairs with perinatal transmission is essential to delineate future therapeutic strategies.
NCT00002179
To evaluate the ability of the combination of indinavir, zidovudine, and lamivudine to suppress HIV-1 infection as measured by: (1) the maintenance of HIV-1 serum viral RNA below the limit of detection of the most sensitive validated assay (ultradirect assay) and (2) absence of evidence of infectious virus in lymph node, cerebrospinal fluid (CSF), peripheral mononuclear cells (PBMCs), and semen. It is hypothesized that the administration of indinavir, zidovudine, and lamivudine will result in: 1. No evidence of infectious virus in lymph node tissue, CSF, PBMCs, and semen samples in 50% of patients who have undetectable viral RNA by the most sensitive validated assay available (ultradirect assay) for at least 48 weeks. 2. Sustained suppression of HIV-1 infection as measured by a decrease in serum viral RNA to below the limit of detection of the ultradirect assay for at least 48 weeks in at least 25% of patients. 3. Suppression of HIV-1 infection as measured by a decrease in serum viral RNA to below the limit of detection of the standard Amplicor assay (i.e., negative) in at least 90% of patients by Week 16. 4. Suppression of HIV-1 infection, suggesting eradication of the virus as measured by maintenance of serum viral RNA to below the limit of detection of the ultradirect assay for at least 24 weeks after discontinuation of indinavir, zidovudine, and lamivudine in patients who have maintained this level of suppression for at least 120 weeks on therapy.
NCT00002213
The purpose of this study is to see if it is safe and effective to give 1592U89 plus 141W94 plus DMP 266 to patients with HIV who have developed resistance to indinavir, ritonavir, saquinavir, or nelfinavir after at least 20 weeks of protease inhibitor treatment. This study also examines how long this combination therapy is effective before patients develop resistance to it.
NCT00002170
The purpose of this study is to see if it is safe and effective to give Viracept to AIDS patients who are being treated for MAC.
NCT00002363
To assess the effects of two doses of synthetic peptide construction 3 ( SPC3 ) on HIV-1 plasma levels (as measured by RNA PCR Amplicor) and on lymphocyte subsets in patients with initial viral load above 10,000 copies/ml. To study the safety of SPC3 and the kinetics of HIV-1 plasma level changes.
