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.
NCT00034255
The purpose of this study is to evaluate the safety and tolerability of single and multiple doses of intramuscular INGAP Peptide given for the first time in humans as a potential treatment for diabetes.
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).
NCT00000663
To determine the safety profile, assess pharmacokinetic properties (blood levels), and obtain preliminary indication of the antiviral and immunologic effects of recombinant CD4 immunoglobulin G (CD4-IgG). CD4-IgG may be effective in blocking HIV transmission and spread, that is, CD4-IgG has antiviral effects. Studies done in adult patients with AIDS and AIDS related complex (ARC) have shown that rCD4 can be safely administered by intravenous bolus, intramuscular or subcutaneous injection. No serious or dose-limiting, drug-related toxicities have been observed to date.
NCT00002151
To characterize the safety and efficacy of fixed doses of MDL 28,574A administered alone and in combination with zidovudine ( AZT ) in patients with asymptomatic or mildly symptomatic HIV infection. To examine the demographic effects on population pharmacokinetics and pharmacodynamics of MDL 28,574A alone and in combination with AZT.
NCT00002357
To obtain preliminary information on the safety, tolerability, and antiretroviral activity of HBY 097 alone or in combination with zidovudine ( AZT ) versus AZT alone. PER 1/19/96 AMENDMENT: AZT monotherapy arm was eliminated.
NCT00002048
To evaluate the safety and tolerance of chronic administration of Retrovir (AZT) in HIV-infected adult patients without clinical manifestations of disease. To assess the efficacy of AZT therapy in the treatment of HIV disease in these patients.
NCT00002015
To evaluate the pharmacokinetics of intravenous ganciclovir in children (ages 3 months - 12 years). To determine the safety and tolerance of a 2 to 3 week induction course of ganciclovir IV in immunocompromised children receiving treatment for life- or sight-threatening cytomegalovirus infections.
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.
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.
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.
NCT00002389
To compare the durability of the viral load response following 48 weeks of treatment with 1592U89/lamivudine (3TC)/zidovudine (ZDV) versus 3TC/ZDV alone. To compare the early antiviral activity following 16 weeks treatment with 1592U89/3TC/ZDV versus 3TC/ZDV alone as demonstrated by the proportion of subjects with viral load \< 400 copies/ml, plasma HIV-1 RNA profiles and CD4+ profiles. To assess the safety and tolerance following 16 and 48 weeks of treatment with 1592U89/3TC/ZDV versus 3TC/ZDV alone.
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.
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.
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.
NCT00002238
To evaluate the safety and efficacy of interferon beta (Betaseron) in AIDS and advanced AIDS related complex (ARC) patients receiving a reduced-dose zidovudine (AZT) regimen.
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)
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.
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.
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.
