Active clinical trials for "Infections"

This study will compare the efficacy, safety and tolerability of intravenous ertapenem versus another intravenous antibiotic in the treatment of moderate to severe diabetic foot infections.

The aim of the study is to determine if N-acetylcysteine (a potent free radical scavenger) prevents the occurrence of adverse neonatal outcomes in preterm deliveries complicated by infection associated with preterm labor or preterm premature rupture of membranes (PPROM). The working hypothesis is that in pregnancies complicated by intra-amniotic infection or inflammation, N-acetylcysteine protects the fetus by preventing the development, or decreasing the intensity and/or progression of the fetal inflammatory syndrome.

To evaluate the effective duration (in days) to clinical improvement of outpatient antibiotic regimens in the treatment of superficial abscesses caused by MRSA in patients that present to the emergency department.

The hypothesis is that an antiviral drug (valacyclovir) will reduce the amount of Epstein-Barr virus (EBV) in the mouths of university students with infectious mononucleosis (mono) while being a safe drug. Because EBV is the cause of mono, it is expected that reduction of the amount of virus could result in faster recovery from the disease.

This 2 arm study will evaluate the efficacy, safety and tolerability of saquinavir/ritonavir or lopinavir/ritonavir in combination with emtricitabine/tenofovir in patients with human immunodeficiency virus type 1 (HIV-1) infection who have received no prior HIV treatment. Patients will be randomized to receive either saquinavir/ritonavir 1000/100mg oral (po) twice daily (bid) + emtricitabine/tenofovir 200/300mg po once daily (qd), or lopinavir/ritonavir 400/100mg po bid + emtricitabine/tenofovir 200/300mg po qd. The anticipated time on study treatment is 3-12 months, and the target sample size is 100-500 individuals.

This study will test the safety and immunogenicity of the gp120/NefTat/AS02A vaccine candidate in individuals with chronic HIV-1 infection successfully treated with HAART. The rationale for this study is based on previous scientific experiments, including data indicating that this vaccine can elicit strong HIV-1-specific T cell immune responses in humans and monkeys and lead to a retardation of HIV-1 disease progression in animal models of HIV-1 infection. The HIV vaccine to be administered during this study consists of three recombinant HIV clade B viral antigens: the envelope glycoprotein gp120 and two regulatory proteins, Nef and Tat.The antigens are formulated in a proprietary adjuvant, AS02A, comprised of two immunostimulants in an oil-in-water emulsion (gp120/NefTat/AS02A). The vaccine and the adjuvant are manufactured and provided for the study by GlaxoSmithKline Biologicals, Rixensart, Belgium. The drugs will be given by intramuscular (IM) injection at a standard dose of 20 mg together with 0.5 ml of the AS02A adjuvant. Twenty HIV-1 infected individuals will be randomly enrolled into three different study groups, receiving either the gp120/NefTat/AS02A vaccine (10 individuals), the AS02A adjuvant alone (5 individuals) or a placebo (5 individuals). After obtaining informed consent, subjects will have a history and physical exam performed and have laboratory tests to confirm they meet all inclusion and exclusion entry criteria. Women of childbearing potential will have a pregnancy test prior to each injection of the investigational product. Injections with vaccine, adjuvant alone, or placebo will then be performed at weeks 0, 4, and 12. Study participants will undergo close monitoring after each vaccination. Blood samples will be obtained for immunological assays at study baseline (2 times) and weeks 2, 4, 6, 12, 14, 24, and 48. All patients will maintain their antiretroviral treatment regimen during the entire study period.

Successful therapy of both tuberculosis and HIV disease share similar problems: pill burden, drug interaction, adherence challenge and toxicity. This study will test the efficacy and safety of a once daily antiretroviral regimen in HIV-tuberculosis coinfected patients.

This is a randomized multicentre trial of emtricitabine (FTC) versus tenofovir (TDF)/FTC in antiretroviral naive subjects with HIV/HBV co-infection over 48 weeks (Clinical Trial A). Plus, a 12 week viral kinetic substudy comparing a subgroup of patients on Clinical Trial A is being conducted. (Substudy A1)

This study will test the safety and efficacy of an investigational Human Immunodeficiency Virus (HIV) vaccine. Efficacy will be measured by either prevention of HIV infection or control of HIV viral load in subjects who become HIV infected. On September 18, 2007 the Protocol V520-023 DSMB (Data & Safety Monitoring Board) reviewed data from a planned interim analysis. These data demonstrated that the investigational vaccine candidate was not effective, and all vaccinations in the study were halted. Participants were encouraged to continue to come to the clinic for scheduled visits and ongoing risk reduction counseling since the vaccine was not effective.

The purpose of this study is to determine the effect of an approved medication for adults for an investigational use in pediatric patients 3 months to 17 years for the treatment of complicated intra-abdominal infections or acute pelvic infections.
