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.
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.
NCT00000155
To describe the clinical course of keratoconus and to describe the relationships among its visual and physiological manifestations, including high- and low-contrast visual acuity, corneal curvature, slit lamp biomicroscopic findings, corneal scarring, and quality of life. To identify risk factors and protective factors that influence the severity and progression of keratoconus.
NCT00054730
This study will investigate whether CX516 can improve attention, memory, language, or behavior in adults with Fragile X Syndrome and/or Autism. CX516 is an AMPAKINE® compound. AMPAKINE compounds enhance synaptic strength. There is evidence to suggest that the synapses in the brain of an individual with fragile X syndrome are immature and abnormal. It is possible CX516 may partially correct this synaptic transmission defect and lead to improvement in cognitive and behavioral functioning. There is also reason to believe that these changes caused by CX516 could be helpful in managing cognitive and behavioral symptoms in patients with autistic disorder. Involvement for each participant will last 28 days. Participants will be given study medication, a physical exam, and a variety of cognitive assessment tests to study potential drug effectiveness at improving disease symptoms.
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.
NCT00000780
PRIMARY: To identify, characterize, and co-enroll HIV-infected adolescents into existing and future ACTG (or other NIH-sponsored) HIV treatment protocols through the systematic and recurrent assessment of eligibility. To assess the ability of adolescents enrolled in ACTG 220 to adhere to ACTG (or other NIH-sponsored) HIV treatment protocols; and to define factors that influence the adolescent's ability to enter or adhere to study protocols. SECONDARY: To describe the nature, stage, and progression of HIV infection in adolescents. Little is known about HIV-infected adolescents as a group and, as a result, small numbers of them are currently enrolled in ACTG drug studies. Creative approaches are needed to encourage enrollment of HIV-infected adolescents whose socio-demographic profile has made access to NIH-sponsored research unlikely.
NCT00001989
This study involves GLQ223 administration to patients who have not previously been exposed to it, but who have received at least 9 months of zidovudine therapy. Efficacy evaluations will include survival, opportunistic infections, T4 cell count, and assessments of viral load.
NCT00002356
To evaluate the efficacy and safety of ISIS 2922 in AIDS patients with Cytomegalovirus ( CMV ) retinitis who are unresponsive or intolerant to ganciclovir and/or foscarnet but are otherwise ineligible for ISIS Pharmaceuticals' controlled trials OR who have failed ISIS 2922 therapy on another controlled clinical trial. PER 2/8/96 AMENDMENT: Patients must rollover from another ISIS 2922 controlled trial.
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.
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.
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.
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.
NCT00002330
To compare the time to progression of Cytomegalovirus (CMV) retinitis among each of three doses of oral ganciclovir, as well as to intravenous therapy, when given as maintenance for 26 weeks. To compare the safety and tolerance among oral doses of ganciclovir at the study doses, as well as to intravenous therapy, when administered as maintenance for 26 weeks.
NCT00002218
To determine the maximum tolerated dose of CI-1012 in late-stage HIV-1-infected patients. To determine the antiretroviral activity of CI-1012 when added to combination therapy. To assess the multiple-dose pharmacokinetic characteristics of CT-1012 when added to combination therapy. To assess the effect of CI-1012 on the pharmacokinetics of other antiretroviral agents.
NCT00008489
The purpose of this study is to compare gastrointestinal (stomach and intestines) side effects of 2 forms of Videx in HIV-infected patients. Videx can be an effective anti-HIV treatment but many patients will not take the medication due to its side effects. Videx EC is a capsule form of the drug and may have fewer side effects. Also, patients would not have to take as many pills since patients taking Videx EC would have to take only 1 capsule per day instead of 2 tablets per day. This study will see if patients taking Videx EC have fewer side effects.
NCT00002265
To demonstrate that zalcitabine (dideoxycytidine; ddC) monotherapy is safe and tolerable in the treatment of patients with AIDS or advanced AIDS related complex (ARC) who previously demonstrated intolerance to zidovudine (AZT) treatment while in Protocol N3300 (NIAID ACTG 114) or N3492 (NIAID ACTG 119). NOTE OF CAUTION FOR CONCOMITANT MEDICATIONS ON STUDY: Patients on amphotericin, pyrimethamine, sulfadiazine, trimethoprim/sulfamethoxazole, ganciclovir, intravenous pentamidine, intravenous acyclovir or oral acyclovir or other bone marrow or renal toxic drugs may not tolerate concomitant ddC. If these drugs are given concomitantly with ddC, patients should have frequent clinical and laboratory assessments, as appropriate. Drugs that are nephrotoxic or have the potential to cause peripheral neuropathy might be expected to cause increased toxicity when co-administered with ddC. Drugs that could cause serious additive toxicity when co-administered with study medication will be allowed for treatment of an acute intercurrent illness or opportunistic infection at the discretion of the investigator. Their use may be allowed with interruption of study drug for up to 35 days per episode, for a total of 90 days for the study. If the patient's condition requires chronic administration of these medications, the patient will be discontinued from study medication and followed.
