Active clinical trials for "HIV Infections"

Switching from enfuvirtide to raltegravir in the treatment of HIV-infected patients who sustain viral suppression with a combination therapy including enfuvirtide (or : with an enfuvirtide-based combination therapy)

This study will compare the benefit for patients switching from Kaletra® to Invirase® tablets over remaining on Kaletra® (based on randomization), to elicit the lipid benefits inferred in previous studies

The hallmark of HIV infection and AIDS is the continuous attrition of CD4 T cells. One of the mechanisms that may account for the CD4 attrition , is autoimmunity against the CD4 T cells, caused by autologous immune cells. Vaccination against autoimmune reactive T cells has been successfully tried in animal models of autoimmune diseases and is now being tried in patients with Multiple Sclerosis. The purpose of the present study is to test this hypothesis in HIV infection. We will vaccinate HIV infected patients in whom specific autoimmune reactivity against CD4 is present , with their own CD4 reactive T cells. Following that, we shall study the patients and find out if the T cell vaccination caused a rise in CD4 T cell levels, and whether it influenced HIV viral load, as well as HIV and CD4 specific immunity.

For people with HIV who are currently taking specific medications (including Sustiva (efavirenz)) and have no detectable viral load, this study tracks how patients do if they take their medications for five days of the week compared with seven days of the week.

Main objective: To evaluate the applicability of the treatment: To evaluate the treatment toxicity according to the Common Terminology Criteria (CTC) version 3.0 of the National Cancer Institute (NCI). To evaluate opportunistic and non-opportunistic infections after 6 cycles of treatment with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) administered every 14 days and highly active antiretroviral therapy (HAART) in patients with diffuse large B cell lymphoma (DLBCL) and HIV infection. To evaluate the adherence to the treatment with 6 cycles of R-CHOP considering the delays in the administration of the cycles and the reductions in the doses of chemotherapy (planned dose administered in predicted term). Secondary objectives: To evaluate the efficacy of the treatment in patients with DLBCL and HIV infection after 6 cycles of treatment with R-CHOP administered every 14 days (R-CHOP/14): To determine the global response and complete remission tax. To evaluate the duration of the response. To evaluate the probability of event-free survival in 5 years. To evaluate the probability of global survival in 5 years. To identify predictive factors of response after 6 cycles of treatment with R-CHOP administered every 14 days in patients with DLBCL and HIV infection. To evaluate the impact of the therapeutic combination of R-CHOP and HAART in the parameters of the HIV infection (HIV viral load and CD4+ lymphocyte count).

The purpose of this study is to determine the short term safety, tolerance, and antiviral effect of zidovudine (AZT) and amdoxovir (AMDX, DAPD) in combination, and whether the dosage for AZT can be reduced, potentially decreasing side effects, while maintaining antiviral effects. Study hypothesis: DADP in combination with AZT is safe and effective, and AZT dosing may be reduced, resulting in lower levels of AZT-monophosphate associated with toxicity and maintaining levels of AZT-triphosphate associated with efficacy.

To evaluate the pharmacokinetics (PK) of LPV/r with saquinavir in HIV-1 infected children. To evaluate treatment response (clinical, immunological and virological) to LPV/r, SQV in Thai children.

The purpose of this study is to determine if blood levels of the hormonal emergency contraceptive agent, Plan B, are altered by concomitant use with the HIV medication, efavirenz.

The purpose of this pilot study is to determine whether there is a correlation between viral load reduction (at Day 4, 7 or 14) following a short course (14 days) of Maraviroc added to a failing regimen, and the R5 result of the TrofileTM assay at screening.

The current project proposes the comparison of two pharmacologic strategies as adjunctive treatments for the improvement of HIV-associated neurocognitive disruption, additionally to use of HAART. The investigators propose the use of the compound that has shown greatest benefits in this context to date, the lithium, versus the use of a well-tolerated and promising drug in other pathologies with neurocognitive affectation, such as Alzheimer or Parkinson diseases, which is the rivastigmine. In those other diseases, this second compound has recently offered a good tolerability, but also benefits on attention, memory and other neurocognitive areas. Both study groups, patients on therapy with lithium and patients on therapy with rivastigmine, will be compared to a control group, which will not initiate any other treatment (therefore only continuing antiretroviral therapy). The investigators are aware that this proposal will offer new relevant data for the study of neurocognitive improvement in HIV infection, as well will allow a better knowledge of clinical management of HIV-infected patients with CNS disease, an aspect that is a common clinical concern today.
