NCT00023348
Primary Objectives: 1\) To determine the proportion of patients with HIV-related tuberculosis who have abnormal pharmacokinetic parameters for isoniazid and rifabutin. Secondary Objectives: 1. To determine risk factors for abnormal pharmacokinetic parameters for isoniazid and rifabutin. 2. To evaluate the correlation between pharmacokinetic parameters of isoniazid and rifabutin and the occurrence of toxicity attributed to antituberculous therapy. 3. To evaluate the correlation between pharmacokinetic parameters of isoniazid and rifabutin and the efficacy of TB therapy. 4. To define and correlate phenotypic INH acetylator status with the results of genotypic acetylator data obtained in the parent trial.
NCT00023400
Primary Objective: To define the impact of nelfinavir (given at 1250mg bid as part of a combination antiretroviral regimen) on peak levels and area under the curve for rifabutin and the rifabutin metabolite, 25-O-desacetyl rifabutin when rifabutin is given at 300 mg bi-weekly as part of tuberculosis chemotherapy. Secondary Objectives: To compare the pharmacokinetics of nelfinavir given twice daily at 1250 mg bid with twice-weekly isoniazid and rifabutin to the pharmacokinetics of nelfinavir 1250 mg twice-daily in historical HIV-infected patients not receiving isoniazid and rifabutin. To evaluate the correlation between pharmacokinetic parameters of rifabutin and 25-O-desacetyl rifabutin and the occurrence of toxicity attributed to rifabutin in patients with HIV-related tuberculosis. To define detailed pharmacokinetics of isoniazid given at 15mg/kg or 900 mg in patients with HIV-related tuberculosis. To attempt to derive optimal sampling times for nelfinavir and rifabutin pharmacokinetic studies.
NCT00002206
The purpose of this study is to see if it is safe and effective to give adefovir dipivoxil once a day for 4 weeks to HIV-infected patients who never have been treated with anti-HIV medicine. This study also examines how the body processes adefovir dipivoxil.
NCT00002012
To conduct a parallel-group, double-blind, randomized, placebo-controlled study to evaluate the safety and efficacy of an orally administered low dose interferon alfa-n3 as an immunomodulator in the treatment of mild to moderate symptomatic HIV+, AIDS-related complex (ARC) patients.
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).
NCT00002403
The purpose of this study is to see if it is safe and effective to give zintevir (AR177) to asymptomatic (no symptoms) HIV-infected patients. Zintevir belongs to a new class of anti-HIV drugs, the integrase inhibitors. HIV uses the protein integrase to infect a cell. Integrase inhibitors block integrase and may stop replication of HIV.
NCT00002392
To ascertain the effect of thalidomide on immune responses to vaccination with polyvalent pneumococcal polysaccharide vaccine and tetanus toxoid in HIV-infected patients; particularly, on markers of immune activation and parameters of specific, anti-HIV cellular immunity.
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.
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
NCT00002378
To determine the proportion of patients whose plasma HIV-1 RNA level falls below the level of detection (\< 400 copies/ml) at week 24 of study therapy. To determine the absolute change in plasma HIV-1 RNA during the 24 weeks of study treatment. To collect safety data on the treatment regimens. AS PER AMENDMENT 12/12/97: To compare the virologic response of Fortovase (FTV) (Saquinavir) Soft Gel Capsule (SGC) tid plus nucleoside reverse transcriptase inhibitors (NRTIs) versus FTV bid plus NRTIs. Further, to compare the virologic response of FTV tid plus NRTIs versus FTV bid plus Nelfinavir bid plus a NRTI with respect to: the percentage of patients whose plasma HIV-1 RNA level falls below the Amplicor assay level of detection (\< 400 copies/ml) at week 24 and week 48.
NCT00011895
The purpose of this study is to determine the effect of treatment with Trizivir (TZV) plus efavirenz (EFV) or TZV alone on viral load (level of HIV in the blood).
NCT00004985
The purpose of this study is to look at the effectiveness of an anti-HIV drug combination that adds capravirine in patients who have failed their first drug combination treatment.
NCT00004998
The purpose of this study is to see if two different doses of AG1549 plus other anti-HIV drugs are safe and effective in HIV-infected patients who are not taking anti-HIV drugs.
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.
NCT00002446
The purpose of this study is to compare the safety and effectiveness of 2 treatments for thrush (a fungal infection of the mouth and throat) in HIV-positive patients. Fluconazole is a drug that is commonly used to treat thrush. SCH 56592 is a new drug that will be compared to fluconazole.
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.
NCT00000787
