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.
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.
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.
NCT00002069
To determine if ditiocarb sodium (sodium diethyldithiocarbamate; DTC) restores immune and host defense function; if DTC ameliorates the AIDS related complex (ARC) symptoms in patients with AIDS and ARC; if DTC prevents progression from ARC to AIDS or progression of AIDS; and if DTC prolongs survival in AIDS.
NCT00050843
The primary objective of the study is to determine the efficacy of thalidomide for the treatment of anemia in patients with myelodysplastic syndromes (MDS).
NCT00002212
The purpose of this study is to see if it is safe and effective to give Targretin capsules to patients with AIDS-related Kaposi's sarcoma (KS).
NCT00002375
The purpose of this study is to see if it is safe and effective to treat HIV-infected patients with indinavir (IDV) plus nelfinavir (NFV), 2 anti-HIV medications. It is thought that IDV plus NFV will be a safe drug combination for treating HIV.
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.
NCT00002435
To investigate the safety of thymic humoral factor (THF gamma 2), its effect on HIV load based on at least a 75 percent decrease in HIV quantitative PCR RNA copies/ml, and its persistence when administered in combination with an antiretroviral nucleoside derivative (zidovudine; AZT). To assess the effects of THF gamma 2 on T-cells, quality of life, and progression of disease.
NCT00002187
The purpose of this study is to compare the safety and effectiveness of two dosage schedules for ISIS 2922 in the treatment of advanced cytomegalovirus (CMV) retinitis
NCT00002447
The purpose of this study is to compare 2 anti-HIV drug combinations.
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.
NCT00002131
To examine the safety and efficacy of two doses of vesnarinone in patients with AIDS-related Kaposi's sarcoma.
NCT00002234
The purpose of this study is to see if it is safe and effective to give HIV-infected patients a new combination of anti-HIV drugs taken once daily.
NCT00002106
To evaluate the effect of ranitidine on immunologic indicators in asymptomatic HIV-1 infected patients with CD4 counts of 400-700 cells/mm3.
NCT00002332
To evaluate the mechanism whereby thymopentin appears to retard the progressive immune suppression attributable to HIV infection.
NCT00002310
To evaluate the safety and tolerance of topically applied SP-303T in AIDS patients. To observe the effect of this drug on herpes simplex virus lesions in patients who have failed to heal in response to oral or intravenous acyclovir therapy. The lack of alternative treatments for herpes simplex virus infection in patients with AIDS and the development of resistance to acyclovir for patients requiring repeated treatment presents a therapeutic dilemma for physicians. SP-303T has good in vitro activity against resistant strains and offers a convenient and inexpensive means of drug administration in comparison to the use of intravenous medication.
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).
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.
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.
