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.
NCT00002388
The purpose of this study is to see if it is safe to give 1592U89 to HIV-infected patients. This study also examines the effect 1592U89 has on plasma viral load (the level of HIV in the blood).
NCT00002361
The purpose of this study is to see if it is safe and effective to give an anti-HIV drug combination containing indinavir and ritonavir to HIV-positive patients who have failed previous treatment with protease inhibitors.
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.
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)
NCT00000178
This is a randomized placebo controlled, double blind study. Patients who meet eligibility criteria and decide to participate in the study will be randomly assigned to receive either drug treatment or a placebo. Neither the patients nor the participating investigators will know who is receiving the drugs and who is receiving the placebo. Participation involves 15 outpatient clinic visits over a 68 week period. Patients take study medication at varying doses (the maximum dose is 20 mg daily), along with calcium and vitamin supplements.
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).
NCT00002379
To evaluate the safety and tolerance of adefovir dipivoxil and indinavir administered orally in combination with zidovudine, lamivudine, or stavudine in HIV-infected patients with CD4 cell counts \>= 100 cells/mm3 and an HIV-1 RNA baseline copy number \>= 5000 copies/ml. To determine the proportion of patients whose plasma HIV-1 RNA level falls below the level of detection (500 copies/ml) by 20 weeks of study therapy and the average reduction in HIV-1 RNA from baseline through study week 20. To evaluate the durability of the antiviral response through 48 weeks of study in patients who continue on study therapy after week 24.
NCT00001995
To determine if a drug regimen containing rifabutin will eradicate or decrease the numbers of Mycobacterium avium complex (MAC) organisms in blood, improve the symptoms associated with MAC infection, and increase survival in patients with AIDS. To assess the safety of the drug regimen.
NCT00000677
To assess the safety and effectiveness of SCH 39304 as primary treatment of acute cryptococcal meningitis in HIV-infected patients. Safety and effectiveness of maintenance therapy following successful treatment of acute disease are also evaluated. Cryptococcal meningitis is a significant cause of illness and death in HIV-infected patients. Intravenous amphotericin B is effective for acute disease but relapse occurs in the majority of patients. Maintenance therapy is recommended but must be balanced against the multiple toxicities of the drugs used and the problems associated with the weekly administration of intravenous therapy. Treatments that are equally or more effective and less toxic than traditional methods are needed, especially oral therapy. SCH 39304 is an orally active antifungal drug that in animal studies is active against a wide range of systemic fungal infections including infections due to Cryptococcus. Features of SCH 39304 suggest that it might be of value in the treatment of cryptococcal meningitis.
NCT00002368
To evaluate the tolerance, safety, and effectiveness of Viramune in preventing clinical AIDS progression events or death when used in combination with Lamivudine and background nucleoside therapy.
NCT00000179
Agitation affects 70 to 90 percent of patients with AD. Signs of agitation include verbal and physical aggressiveness, irritability, wandering, and restlessness. These behaviors often make caring for patients at home very difficult. Trazodone and haldol are two of the most commonly prescribed drugs for agitation in AD patients. Behavior management, a non drug approach, has been effective in reducing signs of agitation. Researchers have yet to compare the effectiveness of drug versus non drug therapy to treat agitation in AD patients and determine which is the best treatment. The Alzheimer's Disease Cooperative Study, with funding from the National Institute on Aging, is conducting an agitation treatment program at 21 sites in 16 States. This study will assess which of the above treatments is most effective.
NCT00002374
To examine the efficacy of saquinavir SGC (soft gel capsules) in combination with other antiretrovirals in HIV-1 infected patients currently treated with saquinavir HGC (hard gel capsules) measured by the absolute change in plasma HIV-1 RNA during the 24 weeks of study treatment.
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.
NCT00002156
To determine the clinically safe and effective dose of intravitreal ISIS 2922 alone and as an additive antiviral therapy to ganciclovir in AIDS patients with cytomegalovirus (CMV) retinitis.
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.
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.
NCT00055510
This research study is intended to evaluate the safety and effectiveness of 3 different doses of BO-653, an investigational inhibitor of LDL cholesterol oxidation, when given orally twice a day compared to placebo (an inactive substance) in preventing restenosis (closure of vessel) within six months after stent implantation. Patients must be enrolled into this study within 24 hours after the stenting procedure. Additionally, over a 1- to 9-month post-stent period, the study will compare the safety and effectiveness of BO-653 versus placebo for measures of coronary artery vessel size by quantitative coronary angiography, major adverse cardiac events, and effects on the oxidative status of plasma lipids and other plasma components.
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.
NCT00064597
This purpose of this study is to develop noninvasive methods of prenatal diagnosis. Fetal cells can be found in maternal blood. This study is designed to isolate these fetal cells from a sample of the pregnant woman's blood and use those cells to test for fetal chromosome abnormalities.
