Active clinical trials for "HIV Infections"

The purpose of this study is to determine the effect of massage therapy on depression, quality of life and plasma cortisol levels in subjects with advanced HIV disease.

Even though powerful anti-HIV drug combinations have been successful in patients with little or no prior anti-HIV therapy, studies have shown that these treatments are less effective in patients who have been treated with nucleoside analogues. This study will test the safety and effectiveness of adding one or two new drugs to a personalized anti-HIV regimen for patients whose previous HIV treatments have failed.

Antiretroviral Therapy (ART) naive subjects will be enrolled in this clinical research study to test the safety and tolerability of fosamprenavir with or without ritonavir in combination TRIZIVIR and COMBIVIR. Subjects will receive 24 weeks of therapy.

The purpose of this study is to determine if stopping anti-HIV drugs for a period of time is safe and effective for enhancing the immune function of patients with HIV.

To evaluate the efficacy, safety, and pharmacokinetics of lamivudine (3TC) combined with zidovudine (AZT), stavudine (d4T), or didanosine (ddI) in comparison with d4T or ddI monotherapy in HIV-infected patients with no prior nucleoside therapy. 3TC may be uniquely effective in combination with AZT due to the interaction of AZT and 3TC resistance mutations. One explanation is that the M184V mutation, which confers resistance to 3TC, suppresses AZT resistance. This benefit of 3TC may not extend to combination therapy with other nucleoside analogs.

To determine the clinical efficacy of indinavir sulfate or placebo in combination with zidovudine ( AZT ) and lamivudine ( 3TC ) in AIDS patients. Protease inhibitors such as indinavir sulfate may be effective in patients with advanced HIV disease who have received prior AZT therapy. Since studies suggest that triple drug therapy may have an advantage over both monotherapy and two drug therapy, the combination of indinavir sulfate with AZT and 3TC should be evaluated.

To obtain a pharmacokinetic profile of oral ZDV and to determine whether the oral administration of Zidovudine (ZDV) during labor and delivery will provide a similar profile to that obtained with the use of IV ZDV in ACTG 082. To evaluate the tolerance of oral ZDV in this population, defined as the ability to take oral doses and lack of vomiting within 30 minutes of receiving oral study doses. The worldwide use of constant intrapartum ZDV infusions to prevent transmission is not practical or feasible. Approximately 18% of the women in the ACTG 076 trial missed their IV ZDV infusions, even at experienced ACTG sites. There is an urgent need to establish a more practical method of delivering ZDV during labor and delivery that, at minimum, will approximate the rate of ZDV administration utilized in ACTG 082. In the future, this would enable women to start an intensive ZDV regimen during early labor, even prior to reaching the hospital.

To compare two different routes of intermittently administered rhIL-2 with a highly active antiretroviral regimen (HAART) to HAART alone. The comparison is based on the following: proportion of patients achieving at least 50-percent increase in CD4 counts above prerandomization baseline values after 1 year of rhIL-2 and the rate of change in CD4 counts. To compare the safety and tolerance of these regimens and their effect on quality of life. To assess the effects of rhIL-2 when combined with HAART on changes in immune cell phenotypes and function and on HIV viral load and the rate of antiviral drug resistance development. The poor responsiveness of late stage HIV-infected patients to rhIL-2 is thought to occur because of low T cell regenerative capacity and high viral burden. If means were available to effectively suppress virus replication, the indigenous immune restorative responses of the host may be further stimulated and enhanced by rhIL-2. The use of protease inhibitors with nucleoside-analogue combination regimens appears to be most effective in controlling virus replication. High-dose intermittent rhIL-2 administered either intravenously or subcutaneously has been shown to be effective in inducing CD4 responses in a number of studies.

This trial tests the safety and effectiveness of the early use of combinations of anti-HIV drugs in HIV-infected infants and young children in an effort to block virus growth and preserve normal immune functions. Various anti-HIV drug combinations need to be tested in order to find the best way to treat infants and children who have been infected with HIV during birth.

The purpose of this study is to see if it is safe to combine methadone with two HIV protease inhibitors (PIs), ritonavir (RTV) and saquinavir (SQV), in HIV-infected patients not currently taking PIs. This study will measure the interactions between methadone and the PIs. Methadone is used treat addicts and to treat severe pain. In order to find the safest way to use methadone with PIs, it is important to evaluate how they interact.
