Active clinical trials for "Virus Diseases"

Viral infections can profoundly influence alloimmune responses and hamper allograft tolerance induction. Persistent hepatitis C virus (HCV) infection occurs in 50% of liver and 20% of kidney transplant recipients, but the impact of HCV on the acquisition of allograft tolerance has not been elucidated. Liver transplantation constitutes a unique clinical model to address this question, given that up to 20% of liver recipients can completely discontinue immunosuppressive drugs and attain operational tolerance. The goal of our study is to determine the influence of HCV-driven immune responses on the acquisition of operational tolerance in liver transplant recipients following drug weaning, and to assess whether immunosuppression withdrawal ameliorates HCV-induced liver damage. This is a prospective trial in which immunosuppressive drug weaning will be offered to HCV-positive liver recipients (selected on the basis of a high likelihood of tolerance) as a strategy to improve HCV-mediated liver disease.

This will be a randomized, placebo-controlled, double-blind single-center proof of concept study to evaluate the anti-EBV activity of 4 grams of valomaciclovir (2 grams BID) for 21 days in subjects with infectious mononucleosis documented to be caused by primary EBV infection. Otherwise healthy subjects (≥15 years old) referred to us with a clinical diagnosis of primary infectious mononucleosis will be screened and those with laboratory-confirmed primary EBV infection will be enrolled.

This study will evaluate the effectiveness of trauma-focused group therapy for reducing HIV-risk behavior and revictimization among adult women survivors of childhood sexual abuse (CSA).

Valaciclovir (VACV), the L-valyl ester prodrug of aciclovir (ACV), is extensively converted to ACV and L-valine after oral administration. In subjects with normal renal function, ACV is predominantly eliminated unchanged in the urine, with a small proportion metabolized to 9-carboxymethoxymethylguanine (CMMG). The metabolism of ACV to CMMG is thought to involve aldehyde dehydrogenase (ALDH). On the basis of a high proportion of the Japanese population having low-activity ALDH, it can be hypothesized that the conversion of ACV to CMMG is decreased, thereby leading, in patients with renal impairment, to higher plasma concentrations of ACV. This pilot study was conducted to investigate potential relationships between genetic polymorphisms of ALDH2, an isozyme of ALDH, and the plasma pharmacokinetics (PK) of VACV, ACV and CMMG in subjects with end-stage renal disease on hemodialysis.

This study aims to investigate the effect of metformin as host-directed therapy in obese/overweight patients with dengue Primary Objective To evaluate the safety and tolerability of metformin in obese/overweight young adults and children with dengue Secondary Objectives To assess the effect of metformin therapy in obese/overweight patients with dengue on physiological, clinical and virological parameters To assess the immunomodulation effects of metformin therapy in obese/overweight patients with dengue To assess difference in gene expression between treatment group compared to non-treatment population

This prospective, non-randomized, non-controlled clinical trial was conducted to examine the clinical outcomes achieved by using initial high-dose intravitreal ganciclovir injections of ganciclovir in treating cytomegalovirus (CMV) retinitis in patients without human immunodeficiency virus (HIV) infection.

This is a randomized, double-blind, placebo-controlled, multicenter, phase III study to be conducted in infants hospitalized with RSV infection in China. The main objectives of this study are to investigate the efficacy and safety of AK0529 in Chinese infants.

The innovative drug XC221 is planned for use in treatment of acute respiratory viral infections in a double-blind, randomized, placebo-controlled, comparative multicenter study assessing the safety, tolerability and efficacy of XC221 at a dose of 200 mg per day in patients with uncomplicated influenza or other acute respiratory viral infections during the 3-days treatment.

This is a Phase 2, double-blind, placebo-controlled study to determine the dose regimen, safety, tolerability, and efficacy of VP-102 in subjects with External Genital Warts (EGW). This study is divided into two parts (Part A and Part B). Increasing durations of skin exposure to study drug (VP-102 or placebo) will be evaluated in three treatment groups prior to progressing to enrollment in Part B. Part A & B will enroll a approximately 108 subjects completing 4 treatment applications every 21 days and continuing with follow-up assessments at Day 84, 112 and 147.

Purpose of the study: • To obtain additional data on the efficacy and safety of Anaferon in the treatment of acute respiratory viral infections.
