Active clinical trials for "Herpes Simplex"

The purpose of this study is to evaluate the preventive efficacy for HSV infection and safety of valaciclovir (VACV) in the adult and pediatric HSCT patients.

This is a randomized, double-blind, placebo-controlled study to assess the safety and tolerability of V212 when administered to adults with solid tumor malignancy (STM) receiving chemotherapy and to assess the impact of V212 on the development of herpes zoster (HZ) in adults with STM receiving chemotherapy. The primary hypothesis is that vaccination with V212 will reduce the incidence of HZ compared with placebo in adults with STM (lower bound of the 97.5% {one-sided α=0.0125} confidence interval [CI] for the estimated vaccine efficacy in adults with STM be >25%). Participants with hematologic malignancy (HM) were also enrolled and were to be originally included in the primary and secondary objectives and analyses. After an interim analysis demonstrated clear evidence of futility of V212 in the HM population, enrollment of this population was stopped and all HM-related objectives and analyses were made exploratory and are not reported in this record.

This is a randomized, double-blind, placebo-controlled study to assess the safety and efficacy of inactivated VZV vaccine for the prevention of HZ and HZ-related complications in adult recipients of autologous hematopoietic cell transplants (HCTs). The primary hypothesis is that vaccination with V212 vaccine will reduce the incidence of herpes zoster (HZ) compared to placebo when administered to recipients of HCT. The statistical criterion for success requires that the lower bound of the 95% confidence interval for the estimated vaccine efficacy in the V212 recipients (excluding the high-antigen lot) compared with that in the placebo recipients is >25%.

The purpose of the study is to evaluate the safety of Herpes Simplex candidate vaccine (gD2t) with adjuvant and its efficacy to prevent genital herpes disease in HSV positive or negative consorts of subjects with genital herpes disease.

About 80% of the worldwide population is positive on HSV antibodies. In the United States the lifetime prevalence of recurrent herpes labialis is estimated at 20% to 40%, with approximately 100 million episodes occurring in the country every year. In Switzerland about 70% of the adult population is positive on HSV-1 and about 20% is positive on HSV-2. The Herpes simplex virus has a lipid bilayer (virus-envelope), which causes the sensitiveness, to any kind of detergents. Within this bilayer cholesterol molecules are integrated and play a crucial role in virus entry into host cells. In vitro experiments have clearly shown that the depletion of cholesterol in HSV-envelope with 2- HPßCD has inhibited the ability of the virus to infect host cells. The aim of this clinical trial is to reduce the number of Herpes labialis relapse and to provide patients with recurrent Herpes labialis a real benefit, concerning the simple mechanism of action and the negligible side effects. Patients having problems in swallowing the antiviral pills of standard treatment, will find with 2- HPßCD a drug, that just has to be applied on the lips, which increases patient's quality of life tremendously. Trial with medicinal product

The purpose of this study is to evaluate the immunogenicity and safety of GSK Biologicals' HZ/su vaccine in adults ≥ 65 years of age with and without Zostavax® vaccination at least 5 years earlier.

The purpose of this study is to assess the safety and immunogenicity of the GSK Biologicals' HZ vaccine 1437173A administered on either a 0,2-; 0,6- or 0,12-month schedule in adults aged 50 years or above, as the immunogenicity of the HZ vaccine administered at intervals longer than two months is not known.

The purpose of this study is to evaluate the immunogenicity and safety of GSK Biologicals' HZ/su vaccine in adults with solid tumours undergoing chemotherapy.

The purpose of this study is to evaluate the immunogenicity and safety of GSK Biologicals' HZ/su vaccine in subjects' ≥ 50 years of age (YOA) who previously have had Herpes Zoster (HZ). The data collected will be compared with the data from subjects without HZ in other HZ/su trials.

The purpose of this study is to assess immunogenicity and safety of GSK Biologicals' HZ vaccine when its first dose is co-administered with a pneumococcal polysaccharide conjugate vaccine (Prevenar13) in adults aged ≥50 YOA, as compared to the control group where the two HZ/su doses are administered subsequent to Prevenar13.
