Filter by:The purpose of this study is to find out what might increase nerve damage in people with HIV who have taken drugs for treatment of HIV disease. Another purpose is to see if nerve exams are done correctly before clinical research sites enroll HIV-infected patients. Nerve damage is common in patients with HIV infection and can cause serious problems. The factors that place patients at risk are not well understood. This study will examine these factors in patients with advanced HIV infection and who have been taking anti-HIV drugs.
The purpose of the study is to see if Z-100 (an investigational drug) treatment is safe in HIV patients who have never received treatment for their HIV, who have not been taking highly active antiretroviral therapy (HAART) for at least 8 weeks, or who have been stable on their current first or second HAART regimen for at least 12 weeks.
RATIONALE: Antivirals such as ribavirin are used to treat infections caused by viruses. It is not yet known if ribavirin is more effective than standard therapy in preventing pneumonia in patients who have respiratory syncytial virus (RSV) infection following stem cell transplantation. PURPOSE: Randomized phase III trial to compare the effectiveness of ribavirin with that of standard therapy in preventing pneumonia in patients who have RSV infection following stem cell transplantation.
RATIONALE: Antivirals such as valganciclovir act against viruses and may be effective in preventing cytomegalovirus. It is not yet known if valganciclovir is effective in preventing cytomegalovirus. PURPOSE: This randomized phase III trial is studying valganciclovir to see how well it works in preventing cytomegalovirus in patients who have undergone donor stem cell transplantation.
The purpose of this study is to compare the effectiveness, safety, and tolerability of 3 anti-HIV combination treatments that do not use protease inhibitors (PIs). The current rule for starting treatment of HIV infection is to combine members from different classes of anti-HIV drugs, such as 2 nucleoside reverse transcriptase inhibitors (NRTIs) and either a PI or a nonnucleoside reverse transcriptase inhibitor (NNRTI). However, these combinations can be complicated and difficult to take, can cause a number of side effects, and may become ineffective. Combinations that are simpler, better tolerated, and more effective are needed. Because PIs can cause long-term side effects and because HIV can become resistant to many of them at the same time, anti-HIV combination treatments that do not use PIs are being tested.
This study will test the safety, side effects and anti-HIV activity of different doses of capravirine in children and adolescents with HIV infection. Capravirine belongs to a class of drugs called non-nucleoside reverse transcriptase inhibitors (NNRTIs), which prevent the virus from replicating (making more copies of itself). Other NNRTIs are nevirapine, delavirdine and efavirenz. HIV-infected children between the ages of 4 months and 21 years may be eligible for this study if they: 1) have received less than 6 weeks of treatment with antiretroviral drugs; 2) have not benefited from antiretroviral therapy after 12 weeks of treatment; 3) cannot continue antiretroviral treatment because of harmful side effects. For the first week of the study, participants will have a 1-week "washout period" in which they will receive no anti-HIV therapy. During this time, they will have physical, eye and neuropsychologic examinations, blood and urine tests, echocardiogram, electrocardiogram (EKG), chest X-ray, head CT scan and skin tests. These physical exams and tests will be repeated throughout the study to determine changes in health. After the washout period, patients will take capravirine once a day in the morning for 6 days. After each dose, a small amount of blood will be drawn at 8 different times over 12 hours to measure the activity of the drug and HIV blood levels. A heparin lock will be placed in the vein to avoid multiple needlesticks. After the 6 days of capravirine there will be another washout period, this time for 21 days. During this time, doctors will determine the optimum combination therapy for the individual patient. After the second washout, patients will begin combination therapy with capravirine plus at least two other anti-HIV medicines. (These may include a reverse transcriptase inhibitor such as zidovudine, didanosine, lamuvidine, zalcitabine, or stavudine, and maybe one or more protease inhibitors such as ritonavir, nelfinavir, saquinavir, indinavir or amprenavir.) For the first week, patients will have a daily blood test to determine HIV blood levels. Afterwards, treatment will continue on an outpatient basis with clinic visits every 4 to 8 weeks for physical exams, lab tests and other procedures as required. The study will last approximately 48 weeks. Patients who benefit from capravirine therapy may be able to continue to receive the drug from the drug company sponsor or as part of another study, or the protocol for this study may be amended to lengthen the treatment period.
The purpose of this study is to compare changes in HIV levels and certain immune cells among patients at different stages of HIV infection. This study will also see how a combination of stavudine (d4T), lamivudine (3TC), indinavir (IDV), and nelfinavir (NFV) affects these levels. Current findings in anti-HIV drug treatment have led to a greater understanding of the background of HIV. To find the best anti-HIV treatment to eliminate all HIV viruses, cells and tissues infected with the HIV virus are examined after combination anti-HIV treatment, when the level of HIV infection is low. The ERADICATE study will examine the idea that HIV viruses can be eliminated at any stage of infection over time.
The purpose of this study is to see whether taking interleukin-2 (IL-2) and other anti-HIV drugs affects the course of HIV disease in patients with primary HIV infection (the time period that immediately follows infection with HIV). After primary HIV infection, the actual infection is spread through an increasing amount of HIV virus in the body. Studies have shown that, by taking a combination of anti-HIV drugs, it is possible to reduce the amount of HIV in the body to almost undetectable levels. This study will find out if starting anti-HIV drugs during primary infection will interrupt or reduce the spread of HIV in patients' bodies.
The purpose of this study is to find out if it is possible to conduct a group counseling program for women at risk for HIV infection. Women have been the fastest-growing group with new AIDS diagnoses. The need for ways to reduce HIV infection in women is urgent. It is important to reduce the risk of HIV infection through sexual contact, but it is also important to address drug use. Group counseling may be an effective method.
The purpose of this study is to find out if anti-HIV drugs, taken by patients who are newly infected with HIV, can make the level of HIV in the body too low to detect. Studying patients who recently have been infected with HIV may help researchers understand how HIV infection works and how anti-HIV drugs may help these patients. Approved anti-HIV drugs can reduce the amount of HIV, but more research needs to be done in newly infected patients. This study will look at recently HIV-infected patients to study the progression of HIV disease and to see whether anti-HIV drugs can reduce the level of HIV.
