Active clinical trials for "Infections"

This study will evaluate the efficacy and safety of a vaginal product compared with that of another vaginal product in the treatment of vaginal infections.

The purpose of this study is to compare the safety, tolerability and effectiveness of the experimental drug GS-9190 when administered for 24 or 48 weeks with peginterferon alfa 2a and ribavirin for the treatment of genotype-1 chronic hepatitis C infection.

The purpose of the study is to find out whether an experimental autologous dendritic cell vaccine is safe, well tolerated, and whether it can strengthen the immune system's response to HIV.

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.

The majority of Human immunodeficiency Virus (HIV)/Hepatitis C Virus (HCV) co-infected patients are non responders after 48 weeks of the current standard-of-care with Peg-Interferon/Ribavirin. The results of re-treatment are disappointing. The addition of Boceprevir to the current standard-of-care has been shown to increase the efficacy of therapy in HCV mono-infected patients previously treated with a bi-therapy. Knowing that HIV/HCV co-infected patients are subject to more rapid hepatic fibrosis as well as to increased risks of cirrhosis, end-stage liver disease and hepatocellular carcinoma, it is important to improve the response rate of the re-treatment of hepatitis C in these patients. The aim of this pilot study is to evaluate the efficacy and safety of Boceprevir in combination with Peg-Interferon alfa 2b plus ribavirin, in patients co-infected with HIV and chronic genotype 1 HCV, and previously treated with Peg-Interferon/Ribavirin. 80 subjects will be enrolled. The primary endpoint will be the Sustained Virologic Response (SVR) defined as undetectable HCV-RNA at Week 24 after the end of therapy.

A major factor in the respiratory health of Cystic Fibrosis (CF) participants is the prevalence of chronic Pseudomonas aeruginosa (Pa) infections. The Pa infection rate in CF patients increases with age and by age 18 years approximately 85% of CF patients in the US are infected. Liposomal amikacin for inhalation (Arikayce™) was developed as a possible treatment for chronic infection due to Pa in CF patients. The purpose of this study is to determine whether Arikayce™ is effective in treating chronic lung infections caused by Pa in CF participants. The effectiveness, safety, and tolerability of Arikayce™ will be compared to Tobramycin TOBI®, an inhalation antibiotic already available for use.

GV-TH-01 is an open label Phase 1 study of 9 HIV-1 infected adults with suppressed viremia who started anti-retroviral therapy (ART) within 18 months of a negative HIV antibody test. This study has 3 phases. The first phase is the vaccination phase, where patients are vaccinated with pGA2/JS7 (JS7)DNA and MVA62B vaccines on a prime/boost regimen. The second phase of the study is a treatment interruption phase, whereby ART is interrupted for a 12 week period approximately 8 weeks following the last vaccination. The third phase occurs after the 12 week treatment interruption phase and is called the treatment reinstitution phase, because subjects reinstitute ART and are followed for an additional 24 weeks. The primary objective is to evaluate the safety of the vaccines during the three phases of the study. A secondary objective is to evaluate the immunogenicity of the vaccines during the vaccination phase of the study.

The study is now completed

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.

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.
