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.
NCT00001018
To determine the pharmacokinetic profile of single doses of letrazuril in patients with AIDS-related cryptosporidial diarrhea; to determine the dose proportionality of single escalating doses of letrazuril; to determine steady-state concentrations of letrazuril; to evaluate the safety and efficacy of escalating doses of letrazuril, compared with placebo, for patients with AIDS-related cryptosporidial diarrhea. Letrazuril, the p-fluor analog of diclazuril, has been shown in an animal model to prevent infections by organisms closely related to the intracellular parasite Cryptosporidium. Reliable data are needed to show the effectiveness of letrazuril in treating AIDS-related cryptosporidial diarrhea.
NCT00002082
To evaluate the safety and efficacy of azithromycin in the treatment of intestinal cryptosporidial infection in AIDS patients.
NCT00002105
To determine the efficacy of Stealth liposomal doxorubicin hydrochloride (DOX-SL) in the treatment of moderate to severe AIDS-related Kaposi's sarcoma (KS) by comparison with the established therapy BV (bleomycin/vincristine). To evaluate the safety and tolerance of DOX-SL compared to BV in a population of AIDS patients with moderate to severe KS.
NCT00002163
To evaluate the benefit of adding 1592U89 to current antiretroviral therapies for AIDS dementia complex and to assess the safety and tolerance of the treatment regimens.
NCT00002109
To confirm results from a previous study in which the combination of thymopentin plus zidovudine ( AZT ), an antiretroviral agent, slowed disease progression in HIV-infected asymptomatic patients. To evaluate the efficacy and safety of thymopentin in HIV-infected asymptomatic patients receiving either monotherapy with AZT, didanosine ( ddI ), or stavudine ( d4T ), or combination antiretroviral therapy with AZT / ddI or AZT / zalcitabine ( ddC ).
NCT00002134
To demonstrate the efficacy of oral ganciclovir in preventing new cytomegalovirus (CMV) disease in AIDS patients with unilateral CMV retinitis treated with an intravitreal ganciclovir implant. To compare safety and tolerance, time to progression, quality of life, and survival among patients treated with an intravitreal ganciclovir implant, with and without oral ganciclovir, versus standard intravenous (IV) ganciclovir therapy.
NCT00002143
To determine the efficacy of acitretin in the treatment of psoriasis in HIV/AIDS patients. Etretinate, a retinoid, has proven successful in the treatment of HIV-infected patients with psoriasis, but it has an elimination half-life of 100 days. Acitretin, a metabolite of etretinate, has a much shorter half-life of 2 to 3 days. Acitretin has proven effective in treating psoriasis in patients without HIV infection by reducing skin involvement and clearing of the condition, but it has not been thoroughly evaluated in HIV-infected patients.
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.
NCT00002195
The purpose of this study is to see if it is safe and effective to add 141W94 to an anti-HIV regimen that includes retrovir plus epivir.
NCT00000828
To identify patterns of zidovudine ( AZT ) susceptibility among mother/infant pairs with perinatal HIV transmission. Most HIV-infected infants acquire their disease via perinatal transmission. Since transmission of HIV-resistant strains to infants could alter the course of disease and response to currently recommended treatment, a study to assess the patterns of AZT susceptibility among mother/infant pairs with perinatal transmission is essential to delineate future therapeutic strategies.
NCT00002229
The purpose of this study is to see if it is safe and effective to give saquinavir (as a soft gel capsule taken by mouth) along with 2 other anti-HIV drugs to HIV-infected patients.
NCT00002226
The purpose of this study is to see if it is safe and effective to give SU5416 to HIV-infected patients with AIDS-related Kaposi's sarcoma (KS). SU5416 may prevent the growth of KS tumors.
NCT00218881
To compare HIV testing rates in ED patients offered video-assisted informed consent off-hours versus those referred to an HIV counselor the next business day.
NCT00002065
To assess the safety and efficacy of depot disulfiram as a new treatment for AIDS and AIDS related complex.
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.
NCT00002184
To evaluate the safety and tolerance of the combination of adefovir dipivoxil at two comparative doses and nelfinavir plus saquinavir SGC administered orally (Group 1) vs. the combination of adefovir dipivoxil and nelfinavir plus either zidovudine, lamivudine, or stavudine (Group 2) vs. the combination of adefovir dipivoxil and saquinavir SGC plus either zidovudine, lamivudine, or stavudine (Group 3) in HIV-infected patients with prior nucleoside reverse transcriptase inhibitor therapy but no prior exposure to protease inhibitors who have CD4 cell counts \>= 100 cells/mm3 and an HIV-1 RNA baseline copy number \>= 5000 copies/ml. To determine the proportion of patients whose plasma HIV-1 RNA level falls below the level of detection (\<500 copies/ml) at 20 weeks of study therapy and the average reduction in HIV-1 RNA from baseline through study week 20. To evaluate the durability of the antiviral response through 48 weeks of study in patients who continue on study therapy after week 24.
NCT00002142
To evaluate the safety and tolerance of cidofovir (HPMPC) infusions in AIDS patients with relapsing cytomegalovirus (CMV) retinitis. To determine the time to retinitis progression in this patient population. To evaluate the impact of cidofovir therapy on visual acuity.
NCT00002451
The purpose of this study is to see if it is safe to give indinavir (IDV) and ritonavir (RTV) in combination with stavudine (d4T) and lamivudine (3TC) to HIV-positive patients who have never received anti-HIV therapy. This study will look at the effectiveness of this drug combination and side effects.
