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.
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.
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.
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).
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.
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.
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.
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.
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.
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.
NCT00049803
The initial portion of the protocol involves discontinuing any medications for cataplexy that the patient may be taking. Subsequently, the patient is prescribed a dose of oral solution of study drug or placebo over a 10-11 week period. During the trial, narcolepsy symptoms will be evaluated. Participants are allowed to continue using stimulant medications at constant doses during the study. A total of 1 to 3 daytime visits in addition to 4 overnight visits to the sleep center will be required to complete the study.

NCT00008554
The purpose of this study is to compare GW433908 and nelfinavir when each is given with abacavir and lamivudine to HIV patients who have not taken antiretroviral drugs.
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.
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.
