Active clinical trials for "Acquired Immunodeficiency Syndrome"

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).

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 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.

Integrase is an enzyme produced by HIV so that the virus can multiply in the human body. GSK1349572 is a new drug in the integrase inhibitor class that prevents the enzyme from working properly and therefore prevents the virus from multiplying. GSK1349572 has shown to be effective against viruses in a short-term monotherapy study in adults with no previous exposure to integrase inhibitors. The purpose of this study is to determine whether GSK1349572 is effective in the treatment of HIV-infected patients who no longer respond to treatment with the approved integrase inhibitor raltegravir and carry viruses with resistance to this drug. The safety and efficacy of GSK1349572 50mg once daily in combination with the background HIV drugs previously administered (unless discontinuation of a particular drug is required) will be assessed over 10 days (functional monotherapy phase), followed by the evaluation of the safety and efficacy of GSK1349572 given with a new optimised background regimen from Day 11 through at least Week 24.

This Phase IIb study in HIV-infected antiretroviral naive subjects will select an optimal once daily dose of GSK1349572 from a range of doses for future evaluation.

The purpose of this study is to evaluate the pharmacokinetics (what the body does to the medication), safety and antiviral activity to support dose recommendations by body weight of darunavir with low-dose ritonavir (DRV/rtv), in combination with other antiretroviral drugs (ARVs), in treatment-experienced Human immunodeficiency virus 1 (HIV 1) infected children.

Evaluate and record any changes in the Quality of Life and psychological state of the affected study group following treatment with Bio-Alcamid. Evaluate the safety and efficacy of Bio-Alcamid for restoring the natural fullness and contours of the face affected by HIV drug-induced lipoatrophy. Pre-treatment classification and post treatment recording of changes will be performed by, both, the Principal Investigator and the Treatment Specialist and independently by a 'Blinded' Co-Investigator at post treatment Week 12. Safety data for Bio-Alcamid will be collected throughout the duration of the study. Safety will be determined by the rates of procedure-related events and adverse experiences associated with the use of Bio-Alcamid.

In the last years Structured Treatment Interruptions (STI) have been proposed to reduce HAART-related toxicity and to increase patients' compliance. ISS PART is a randomized comparison of repeated STIs versus continuous HAART in chronically HIV-infected subjects with persistent suppression of viral replication. The two arms of the study will be compared in terms of immunological response (proportion of patients with CD4>500/mmc) at 2 years.

The purpose of this study was to compare the safety, tolerability, and antiviral activity of once-daily (QD) and twice-daily (BID) dosing of the lopinavir/ritonavir (LPV/r) tablet formulation in combination with nucleoside/nucleotide reverse transcriptase inhibitors (NRTIs) in antiretroviral-experienced human immunodeficiency virus type 1 infected subjects with detectable viral load while receiving their current antiretroviral therapy.

The impact of lymphatic filariasis (LF) on HIV is assessed by measuring HIV viral load before and after DEC treatment of filariasis in double-infected individuals. The impact of HIV on lymphatic filariasis is assessed by measuring the success of DEC treatment on W. bancrofti antigenaemia and microfilaraemia in double-infected individuals. The effect of DEC treatment in individuals with lymphatic filariasis and/or HIV is assessed by measuring the pre- and post-treatment level of HIV viral load, immunological responses and micronutritional parameters, including antioxidants and markers of oxidative stress, in single- or double-infected individuals. The study is carried out as an anonymous, unlinked and double-blind placebo controlled study with cross-over design. The study groups comprise: 1) 18 double-infected individuals (HIV+/LF+), 2) 16 HIV infected individuals (HIV+/LF-) and 3) 25 individuals with lymphatic filariasis (HIV-/LF+). Based on stratified, blocked randomisation the study participants receive DEC treatment or placebo. Pre- and post-treatment (1 week, 12 weeks and 24 weeks post-treatment) blood samples are collected and analysed for HIV viral load, CD4+ T cell count, distinctive Th1 and Th2 cytokines, circulating filarial antigens (CFA), micronutrient status, antioxidant enzymes and markers of oxidative stress. After 12 weeks the study participants get the opposite treatment and post-treatment blood samples are collected four times with the same intervals as above.
