Active clinical trials for "HIV Infections"

In the third decade of the HIV pandemic, what was once a uniformly and rapidly fatal disease has been transformed into a chronic illness by advances in the understanding of HIV pathogenesis and therapeutics. As a result, HIV-infected individuals are living longer and better lives. This phenomenon, coupled with a continued steady rate of new HIV infections in this country, has led to the highest U.S. HIV prevalence rates since the beginning of the epidemic. In the past, HIV prevention efforts were separate from routine primary care delivery due to multiple factors including stigma and time constraints. Recent events, including increases in sexually transmitted disease (STD) rates among HIV-infected persons and evidence that infected individuals can be super-infected by HIV strains resistant to antiretroviral therapy, have inspired the SPNS program initiative to develop demonstration projects for interventions to reduce risky sexual exposures among HIV-infected patients receiving primary care.

The purpose of this study is to see whether an HIV vaccine, ALVAC vCP205, is safe and can prevent HIV infection. The vCP205 vaccine will be tested with another vaccine, gp160MN/LAI-2.

The purpose of this study is to determine if treatment with an anti-HIV drug containing ritonavir and Agenerase is safe and can lower the level of HIV in the blood in patients who have failed an anti-HIV drug treatment containing nelfinavir.

The purpose of this study is to test 2 different dosing regimens of GW433908/ritonavir (RTV) versus lopinavir (LPV)/RTV when each is given with 2 active reverse transcriptase inhibitors (RTIs), in patients who have taken anti-HIV drugs without success.

The purpose of this study is to see if giving the anti-HIV drug nevirapine (NVP) to HIV-positive pregnant women and their infants can help reduce the chance that a mother will give HIV to her baby during delivery. NVP is a promising medication for blocking HIV transmission from HIV-positive mothers to their infants. NVP is inexpensive and is easily absorbed by the mother and transferred to the infant. It is thought that even a single dose to the mother and infant may provide enough protection to the baby during the time of exposure to HIV at birth.

This study is designed to investigate the acceptability, perceived need and uptake of short-term episodic Pre-Exposure Prophylaxis (PrEP) for HIV prevention among men who have sex with men (MSM). The overall objective is to determine the feasibility of a clinic-based Epi-PrEP implementation pilot project for 50 MSM (25/each of the 2 study sites) who report occasional condomless sex and who anticipate a period of high-risk while away from home (e.g. vacation) during the study period.

The objective of the study is to evaluate the feasibility and interest of a HIV quarterly preventive global care for men who have sex with men (MSM) in sub-Saharan Africa to help reducing HIV incidence in this key population, their female partners, and the general population. This interventional, open label, multicenter, multidisciplinary cohort study will be conducted in Burkina Faso, Ivory Coast, Mali and Togo. All participants will receive a HIV quarterly preventive global care including: i) data collection on health status, symptoms of sexually transmitted infections (STI) and sexual behavior, ii) a clinical examination, iii) STI diagnosis and treatment, iv) counselling adapted for MSM, and v) the provision of condoms and lubricants.

The purpose of the study is to screen the optimal intervention strategies to rapid establish the protective barriers against HIV-infection by maximally decreasing the viremia among HIV- infected patients.

This study is being conducted to determine if the uptake of anti-HIV medication, called Genvoya®, at different time-frames, is different at several body sites, including mucosal tissues. This medication might be considered for on-demand PEP regimens in the future.

The objective of this study is to clarify whether if starting antiretroviral treatment based on dual therapy (DTG + 3TC) could provide less control of residual HIV replication and, therefore, a detriment on immune activation and inflammation compared to starting with triple therapy, and could worsen the patients' long-term prognosis. For this purpose, the investigator has designed a randomized clinical trial where will assess the immunological recovery (CD4+/CD8+), immune activation, proliferation, senescence and apoptosis in T lymphocytes CD4+ and CD8+ cells by flow cytometry, the immune activation of monocytes/ macrophages and plasma concentrations of various inflammatory mediators by ELISAS, and the thymic function, the cellular reservoir of HIV and the degree of HIV DNA transcription by digital dropped PCR.
