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.
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.
NCT00001995
To determine if a drug regimen containing rifabutin will eradicate or decrease the numbers of Mycobacterium avium complex (MAC) organisms in blood, improve the symptoms associated with MAC infection, and increase survival in patients with AIDS. To assess the safety of the drug regimen.
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).
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.
NCT00002440
The purpose of this study is to see if it is safe and effective to give 1592U89 plus certain protease inhibitors (PIs) to HIV-infected patients who never have been treated with anti-HIV drugs. This study also examines how the body processes these drugs when they are given together.
NCT00002156
To determine the clinically safe and effective dose of intravitreal ISIS 2922 alone and as an additive antiviral therapy to ganciclovir in AIDS patients with cytomegalovirus (CMV) retinitis.
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.
NCT00002437
To determine whether cidofovir (HPMPC) therapy administered by intravenous infusion can extend the time to progression of peripheral cytomegalovirus (CMV) retinitis in AIDS patients. To evaluate the safety and tolerance of HPMPC therapy when administered by intravenous infusion in AIDS patients with CMV retinitis that is not immediately sight-threatening. To evaluate the virologic effects of intravenous HPMPC therapy on CMV shedding in urine, blood, and/or semen. To evaluate the impact of HPMPC therapy on visual acuity.
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).
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.
NCT00002442
The purpose of this study is to compare the safety and effectiveness of 2 dosing schedules (once daily vs twice daily) of lamivudine (3TC) given with stavudine (d4T) and either indinavir (IDV) or nelfinavir (NFV) for 24 weeks.
NCT00004585
The purpose of this study is to see if a certain combination of anti-HIV drugs is safe and effective in HIV-infected patients. The drug combination includes a tablet containing lamivudine and zidovudine (called Combivir) plus abacavir plus efavirenz.
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.
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.
NCT00002190
To explore the antiviral efficacy, tolerability and safety of saquinavir plus zidovudine plus lamivudine.
NCT00004739
The use of protease inhibitors is increasing in HIV-infected children because this treatment has resulted in improved body weight, improved immune status and less hospitalizations. However, recent reports suggest that these drugs may also be associated with some negative side-effects, specifically a syndrome of diabetes and fat redistribution. Development of the fat redistribution/diabetes syndrome has recently been reported in HIV-infected children, as well as in adults. Diabetes is associated with complications such as increased heart disease, eye disease and loss of kidney function. Thus development of diabetes is a significant problem which could outweigh the benefits obtained by treating patients with protease inhibitors. One major cause of diabetes is lack of normal response to insulin (insulin resistance). Insulin resistance tends to be worse in family members where one or more parent has diabetes, and is also worse in certain ethnic groups. The first major purpose of our study is measure insulin resistance in HIV-infected children who do not take protease inhibitors, and compare our findings to those from patients who are treated with protease inhibitors. We will also follow patients newly treated with protease inhibitors for two years to evaluate changes in insulin sensitivity. These results will be correlated with each patient's family history of diabetes and with ethnicity, and should help us better predict which children are "at risk" for development of diabetes from protease inhibitor therapy. Children with HIV infection often have problems with gaining enough weight and with poor linear growth (height). One likely reason for this is the way their bodies use and store protein. The second purpose of our study is measure protein turnover and to correlate our findings with growth data. We also plan to study the effects of protease inhibitor therapy on protein turnover. We believe that these studies will provide knowledge to help clinicians formulate recommendations for nutritional and medical therapy.
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.
NCT00002257
To compare the time to progression of CMV retinitis between oral ganciclovir and IV ganciclovir during 20 weeks of maintenance treatment. To compare the safety and tolerance of oral ganciclovir with IV ganciclovir therapy during 20 weeks of maintenance treatment. To describe the safety and tolerance of oral ganciclovir treatment when given concurrently with anti-retroviral treatment, e.g. zidovudine or ddI. To describe the survival of people with AIDS and CMV retinitis.
