Active clinical trials for "Herpes Zoster"

Varicella is a vaccine-preventable disease, which can be severe in immunosuppressed children. Currently, the (live) vaccine is not recommended in pediatric orthotopic liver transplant recipients. Furthermore, protection due to naturally acquired immunity to VZV or post-immunization isn't well described in this population.The questions asked are: What is the influence of the immunosuppression required after orthotopic liver transplantation (OLT) on the maintenance of VZV-specific immunity elicited by wild-type varicella infection before OLT transplantation? What is the influence of the immunosuppression required after OLT on VZV-specific immunity elicited by varicella immunization before OLT transplantation? What is the influence of the residual immunosuppression at ≥ 12 months after OLT transplantation on the induction of VZV-specific B and T cell responses elicited by VZV vaccination after OLT transplantation? What is the influence of the residual immunosuppression at ≥ 12 months after OLT transplantation on the persistence / waning of B and T cell responses elicited by VZV vaccination?

This is a phase II study that will examine the immunogenicity of the Shingrix vaccine in patients following an allogeneic stem cell transplant.

The goal of this clinical trial is to assess the safety and immunogenicity of a self-replicating (sr) RNA-based vaccine, JCXH-105, in the prevention of Shingles (Herpes Zoster) Participant will be randomized to receive either JCXH-105 or Shingrix.

Herpes zoster (HZ), also commonly known as shingles, is characterized by a bandlike rash in the dermatome that corresponds to the affected nerve. Pain is prevalent in HZ patients, which may be provoked by light touch. Postherpetic neuralgia (PHN) is one of the most common complications of HZ and it is generally intractable to treat. At present, common treatment methods for HZ include anti-inflammatory, antiviral, analgesic, and neuroleptic regimens. Nevertheless, the application of these therapies can sometimes be limited by side effects. In this scenario, it is urgent to seek alternative non-pharmacological therapies for treating HZ. Intradermal acupuncture (IDA) is a common type of acupuncture. By retaining the needles for a much longer duration than other common modalities of acupuncture, IDA can prolong the sustained effect of acupuncture. In addition, characterized by mild pain during the insertion of intradermal needles, IDA is more suitable for patients who fear conventional acupuncture and it is also easy to operate by practitioners. Therefore, concerning the treatment of pain conditions, such as acute HZ, it may have certain advantages over conventional acupuncture. Thus, The aim of this trial is to evaluate the efficacy and safety of IDA for acute HZ.

The risk of herpers zoster reactivation is higher in SLE patients than general population. It has shown that mild or even inactive patients could also have varicella zoster virus (VZV) infections, and they account for about two-thirds of the events. And our previous study indicated that recent various VZV infection was associated with increased risk of disease flares. The risk of virus reactivation limited the use of live-attenuated shingles vaccine in SLE patients, especially in whom with high dose of prednisone or immunosuppressants. Whether the introduction of recombinant zoster vaccine could reduce the risk of zoster reactivation in lupus patients is to be explored in this study.

To investigate the immunogenicity, reactogenicity and safety of 2 doses of the adjuvanted herpes zoster subunit vaccine (Shingrix) in patients with SLE in a randomized trial.

This investigator-initiated study will serve as a sub-study for the American College of Rheumatology-sponsored VERVE protocol currently funded by the NIH. This double-blinded multicenter randomized pragmatic trial is designed to determine whether Zostavax or Shingrix are safe and effective in patients with rheumatoid arthritis (RA) currently using anti-tumor necrosis factor (TNF) therapies. Inclusion/exclusion criteria for this sub-study mirror that of the parent VERVE trial with the exception of abatacept therapy being allowed. Preliminary data from the VERVE parent protocol enrolling patients using anti-TNF therapy is encouraging in that few patients experienced adverse events (56 adverse events in 50 participants, out of 140 participants in total) and that 96.2% of these adverse events were considered either mild or moderate. Importantly, there have been no instances of vaccine dissemination or zoster events to date.

The purpose of this clinical study is to learn about the safety, extent of the side effects (reaction to vaccine), and immune response (your immune system's reaction) of the study vaccine called Varicella Zoster Virus modRNA (VZV modRNA). We are seeking for healthy participants who are between 50 and 69 years of age. This study will be conducted in 2 substudies: Substudy A (Phase 1) and Substudy B (Phase 2). Substudy A: This substudy is the Phase 1 portion of the study. In this substudy, participants will receive 1 of 3 VZV modRNA vaccine candidates (different construct, different dose levels and different formulation [frozen or freeze dry powder]) or the approved shingles vaccine intramuscularly. Participants will be assigned in 1 of 11 groups in the study. Vaccination will be given either as a 2-dose series using one of two dosing schedules (either 2-months apart or 6-months apart), or (in one of the groups), as a single VZV modRNA vaccine at the first vaccination visit and saline at the second vaccination visit. Participants will take part in this study for 8 to 12 months depending on the group they are assigned to. Some group(s) will continue into persistence-of-immunity (overtime assessment of effect of vaccine) portion of the study. Those participants assigned to these selected groups will be involved in the study for up to 5 years. Substudy B: This substudy is the Phase 2 portion of the study. In this part of the study, participants will receive either VZV modRNA vaccine at selected dose level/schedule/formulation or approved shingles vaccine. This selection will be determined from Substudy A. Participants will be involved in this study for up to 5 years.

The purpose of the study is to better understand how the immune system responds to the new herpes zoster (shingles) vaccine (Shingrix®). The study will be looking at certain markers in the blood after vaccination with Shingrix®.

This is a randomized, observer-blinded, active-controlled Phase I study to evaluate the safety, reactogenicity, and immunogenicity of REC610, when administered as 2 intramuscular (IM) injections in healthy adults aged 40 years and older, who do not have known HZ and history of varicella or HZ vaccination. The recombinant HZ vaccine, Shingrix® (GlaxoSmithKline), will be used as the active control.
