NCT00002150
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.
NCT00000677
To assess the safety and effectiveness of SCH 39304 as primary treatment of acute cryptococcal meningitis in HIV-infected patients. Safety and effectiveness of maintenance therapy following successful treatment of acute disease are also evaluated. Cryptococcal meningitis is a significant cause of illness and death in HIV-infected patients. Intravenous amphotericin B is effective for acute disease but relapse occurs in the majority of patients. Maintenance therapy is recommended but must be balanced against the multiple toxicities of the drugs used and the problems associated with the weekly administration of intravenous therapy. Treatments that are equally or more effective and less toxic than traditional methods are needed, especially oral therapy. SCH 39304 is an orally active antifungal drug that in animal studies is active against a wide range of systemic fungal infections including infections due to Cryptococcus. Features of SCH 39304 suggest that it might be of value in the treatment of cryptococcal meningitis.
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).
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.
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.
NCT00002227
The purpose of this study is to see if it is safe and effective to give efavirenz plus stavudine plus lamivudine to patients who have never taken anti-HIV drugs.
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.
NCT00002441
The purpose of this study is to see if an HIV vaccine, AIDSVAX B/B, can protect adults who are at risk from becoming infected with HIV. Patients who become infected despite immunization will be studied to see if receiving the vaccine before becoming infected will help keep HIV levels (viral load) low.
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.
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.
NCT00002304
To compare the safety, tolerance, and effectiveness of fluconazole and ketoconazole in the treatment of candidal esophagitis in immunocompromised patients.
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.
NCT00002268
To determine the safety, tolerance, and potential in vivo antiviral effects of five dosage levels and a dose to be determined of human anti-cytomegalovirus (CMV) monoclonal antibody (SDZ MSL-109; formerly SDZ 89-109) when administered once every 2 weeks for a total of 12 doses to patients with either AIDS or eligible AIDS-related complex (ARC) and with culture proven evidence of CMV viremia and/or viruria. Sandoglobulin will be employed as a comparative control.
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.
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.
NCT00006397
The purpose of this study is to see how safe and effective it is to give multi-drug treatment with indinavir (IDV) plus ritonavir (RTV) plus enteric-coated didanosine (ddI) plus stavudine (d4T) and if there are differences in responses between men and women.
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.
NCT00002212
The purpose of this study is to see if it is safe and effective to give Targretin capsules to patients with AIDS-related Kaposi's sarcoma (KS).
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.
NCT00002338
To assess the safety, tolerance, and steady-state pharmacokinetics of multiple oral doses of 935U83 administered to patients with HIV infection. To obtain preliminary evidence of antiretroviral activity of 935U83. To prospectively evaluate the emergence of in vitro drug resistance. To determine the effects of 935U83 dosing on CD4+ cell counts.
