Active clinical trials for "Herpes Zoster"

The objective of this study is to evaluate the safety and tolerability of single rising doses of ASP2151 under fasted condition in healthy male subjects. The study will also evaluate the pharmacokinetics (PK) of a single dose of ASP2151 under fasted versus fed conditions in healthy male subjects.

Vaccination is the most effective way of preventing infectious diseases. Despite the success of vaccines in general, vaccines induce diminished antibody responses and lower protection in the elderly in particular. This could be explained by a defect in the early responses of an ageing immune system. A better understanding of the basic immunological mechanisms that mediate vaccine efficacy is incomplete. Such information is critical and could greatly decrease both the cost and the time to new vaccine development particularly for the geriatric population. In this trial, the investigators will study the immunologic differences of the FDA approved licensed shingles vaccine between a younger and an older group. Thirty three healthy volunteers between the ages of 25-40 and forty four healthy volunteers between the ages of 60-79 will be enrolled in the study. Each participant in the study will be given one shingles shot. Blood work will be obtained one month before vaccination, on the day of vaccination, one day, three days, seven days, fourteen days, one month, three months and six months after vaccination. Throughout the duration of the study, the participants will be monitored for safety.

A new paediatric formulation (oral liquid) has been developed for flexible and accurate dosing of valacyclovir in children. To establish the bioavailability of this new formulation, healthy volunteers will be exposed to the new formulation and to valacyclovir tablets. The concentration of valacyclovir in their blood after exposure to the oral liquid will be measured and compared to the tablet.

Primary objective: To describe the safety profile of a refrigerator-stable formulation of VARIVAX® as a first single dose injection in 12 to 15 month-old infants in the 42-day follow-up period post-vaccination. Secondary objectives: NA

Background: People who have cancer tend to get sick more often. This is in part because of the cancer treatments they get. Because of this, they may get shingles. Scientists had thought people with chronic lymphocytic leukemia (CLL) should not get the shingles vaccine. Now there is a new shingles vaccine that is not live and cannot cause shingles. The new shingles vaccine may protect people with weak immune systems from getting shingles. This is currently shown to be safe to give people 50 years and older to prevent shingles. Researchers want to test how safe the vaccine is and how it works in people with CLL. Objective: To learn how a new shingles vaccine works in people who have chronic lymphocytic leukemia or small lymphocytic lymphoma (SLL). Eligibility: Adults ages 18 years and older with CLL or SLL who are not being treated for CLL or who are getting certain treatments. Design: Participants will be screened with a chart review or through another protocol. Visit 1 At visit 1, participants may have a pregnancy test, blood test, or physical exam. Pregnant participants cannot be in the study. Eligible participants will get the shingles vaccine as an injection. Participants will receive a diary and write down any symptoms they have for 7 days after the vaccines. Visit 2 Visit 2 will be 3 months later. Participants will have blood taken and get another dose of the vaccine. Participants will receive a diary and write down any symptoms they have for 7 days after the vaccines. Visit 3 Visit 3 will be 3 months after visit 2. Participants will have blood taken. Participants may be able to get an additional vaccine the same day as the shingles vaccine.

Vaccines are used to prevent infectious diseases worldwide. Unfortunately, many vaccines, like the flu vaccine, are less effective in older adults. This single-centre open label partially randomised, partially placebo-controlled trial evaluates the differences in immune response between young and older adults after vaccination with a quadrivalent inactivated influenza vaccine and an adjuvanted herpes zoster vaccination. Exploring the underlying mechanisms between the differences in immunogenicity can provide important information for future vaccine development.

Primary objective: To compare if, when given concomitantly with VARIVAX® by the same route at 12-18 months of age using separate injection sites, a single dose of M-M-RTMII administered by IM route is as immunogenic as a single dose of M-M-RTMII administered by SC route in terms of response rates to measles, mumps and rubella at 42 days following the vaccination. AND/OR To compare if, when given concomitantly with M-M-RTMII by the same route at 12-18 months of age using separate injection sites, a single dose of VARIVAX® administered by IM route is as immunogenic as a single dose of VARIVAX® administered by SC route in terms of response rate to varicella at 42 days following the vaccination Secondary objectives: To summarise the antibody titres to measles, mumps, rubella and varicella at 42 days following the vaccination in children immunised with M-M-R™II and VARIVAX® administered concomitantly at two separate injection sites by the same route IM or SC, To evaluate the safety profiles of M-M-R™II and VARIVAX® administered concomitantly at two separate injection sites by the same route IM or SC.

The purpose of this study is to learn more about the immune response to varicella zoster virus (VZV).

The aim of this research is to study and compare the efficacy and safety of single injection erector spinae plane block and thoracic paravertebral block in prevention of post herpetic neuralgia in patients with acute thoracic herpes zoster.

This study will test the immunogenicity, safety, and tolerability of VARIVAX™ manufactured with the Varicella Enhanced Process (VEP) compared with the VARIVAX™ 2007 Process. The primary hypotheses being tested are 1)VARIVAX™ VEP will induce varicella-zoster virus (VZV) antibody responses that are non-inferior to those induced by VARIVAX™ 2007 process at 6 weeks after vaccination 1, and 2) VARIVAX™ VEP will induce an acceptable anti-VZV antibody response rate at 6 weeks after vaccination 1.
