Filter by:A study in two parts (Part A and Part B) to evaluate the responsiveness of various biomarkers of immunity to Varicella-Zoster Virus (VZV) following repeated immunizations with heat treated VZV vaccine V212 or with Zostavax™. The enrollment of participants into this study was conducted in 2 parts, Part A and Part B. The first 42 eligible participants were enrolled into Part A of the study. In Part A, the reaction of the VZV skin test at baseline was evaluated at both 48 and 72 hours post administration of the VZV skin test reagent and saline (in opposite arms), with 2 examiners performing the reading at each timepoint; all subsequent skin test readings in Part A were performed at 48 hours post administration. After all skin test reactions were obtained at baseline for the 42 subjects in Part A, an interim analysis was performed (1) to assess the frequency of baseline negative skin tests in order to confirm that the planned sample size (N=120) was adequate for an evaluation of the effect of vaccination on the VZV Skin Test, and (2) to assess the frequency of baseline positive skin tests at 72 hours relative to 48 hours (post administration) in order to determine the preferred time for evaluation of the skin test reaction. The interim analysis from Part A confirmed the study sample size, an additional 78 subjects were enrolled into Part B to achieve the planned sample size (N=120). The study procedures for Part B of the study were identical to those in Part A with the following exceptions: (1) baseline skin test readings were performed only once, at either 48 or 72 hours (post administration) to accommodate the scheduling of clinic visits, and (2) only one examiner was needed for the skin test reading at baseline.
Symptoms that herald herpes zoster include pruritus, dysesthesia and pain along the distribution of the involved dermatome. The most distressing symptom is typically pain and the most feared complication is postherpetic neuralgia (PHN), the persistence of pain long after rash healing. PHN is defined as pain persisting more than 3 months after the rash has healed. Both, the acute pain associated with herpes zoster and the chronic pain of PHN, have multiple adverse effects on health-related quality of life. The primary objective of the trial presented is to investigate whether a 4 week semi-standardised acupuncture is non-inferior (first step) or superior (second step) to (a) the anticonvulsive drug gabapentin and (b) sham laser acupuncture in the treatment of pain associated with herpes zoster in addition to standardised analgesics. Secondary objectives include an assessment of the change of sensoric function, of long-term effectiveness, the occurrence of PHN and an evaluation of several pain specific questionnaires
Herpes zoster, or shingles, is the result of a viral infection that causes a painful skin rash, usually in older people or people with suppressed immune systems like those infected with HIV. The ZOSTAVAX vaccine has been shown to reduce the number of infections and symptoms of herpes zoster infection in people over the age of 60. The purpose of this study is to evaluate the safety, tolerability, and immunogenicity of two doses of ZOSTAVAX in HIV-1-infected adults with conserved immune function (Cd4+ T cell counts >=200 cells/uL) virologically suppressed on potent combination antiretroviral therapy (ART).
This study will compare ProQuad™ and concomitant administration of M-M-R™ II and Varivax™ with respect to immunogenicity, safety and tolerability. The primary hypothesis to be tested is that the antibody response rates to measles, mumps, rubella, and varicella 6 weeks after vaccination with ProQuad™ will be non-inferior to the antibody response rates after vaccination with concomitant M-M-R™ II and Varivax™.
The purpose of this study is to determine the pharmacokinetics and dosage of EPB-348 that best balances safety and efficacy among adult immunocompetent patients with an acute episode of herpes zoster.
The objective of the present study is to assess and document the safety of a second dose of Varicella Biken vaccine administered at 4 to 6 years of age in healthy children having previously received a first dose of Varicella Biken vaccine. All subjects will receive a second dose of Varicella vaccine (Varicella Biken) at 4 to 6 years of age. The expected total duration of follow-up (first visit to last visit) for each subject will be one month.
The goal of this randomized observer-blind trial is to further refine the formulation of vaccines containing GSK1437173A in older adults by comparing the cellular and humoral immune responses and the safety profiles of the different formulations.
This study aims to assess the immunogenicity and safety of varicella vaccination in a population of autologous peripheral stem cell/ bone marrow transplantation recipients who have reached at least four months post-transplantation.
This Phase 3b study is being conducted for the purpose of registration of the GSK208136 vaccine in Korea.
The purpose of this study was to assess the safety and tolerability of gamma-irradiated varicella-zoster virus (VZV) vaccine A (Part 1) and gamma-irradiated VZV vaccine B and C (Part 2) and to determine if they were immunogenic when administered to healthy individuals, as measured by VZV-specific antibody responses by glycoprotein enzyme-linked immunosorbent assay (gpELISA). The primary hypothesis was that gamma-irradiated VZV vaccine A (Part 1) and gamma-irradiated VZV vaccine B and C (Part 2) would elicit an acceptable VZV-specific immune response. The secondary hypothesis for Part 1 of the study was that heat-treated VZV vaccine would elicit an acceptable VZV-specific immune response.
