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.

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.
NCT00002304

NCT00038636
The purpose of this study is to determine the safety and effectiveness of a high dose of ABT-378/ritonavir
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.
NCT00002082
To evaluate the safety and efficacy of azithromycin in the treatment of intestinal cryptosporidial infection in AIDS patients.
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.
NCT00002096
To determine whether there is a pharmacokinetic drug interaction between oral ganciclovir and oral zidovudine (AZT) and between oral ganciclovir and oral didanosine (ddI). To determine whether concurrent administration of probenecid affects the pharmacokinetics of oral ganciclovir. To obtain data on the short-term safety of oral ganciclovir administered concurrently with AZT, ddI, or probenecid in HIV-positive patients.
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).
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.
NCT00002171
The purpose of this study is to see if it is safe and effective to give Viracept plus stavudine (d4T) plus lamivudine (3TC) to HIV-positive women with a CD4 count \<= 400 cells/mm3. This study also examines how the body handles Viracept when given with d4T and 3TC.
NCT00002130
To examine the continued safety and tolerability of four doses of vesnarinone in HIV-infected patients who have completed a short-term study (less than 12 months on continuous treatment) of the drug.
NCT00002116
To evaluate the safety and tolerance of topical cidofovir (HPMPC) therapy for refractory mucocutaneous herpes simplex virus disease in AIDS patients. To determine whether topical HPMPC therapy can induce re-epithelialization and healing of refractory mucocutaneous herpes simplex virus disease in AIDS patients. To evaluate the virologic effects of topical HPMPC therapy on herpes simplex virus shedding from refractory lesions.
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.
