Filter by:Introduction: Patients with autoimmune rheumatic diseases (ARDs), rheumatoid arthritis (RA), juvenile idiopathic arthritis (JIA), psoriatic arthritis (PAs), ankylosing spondylitis (AS), systemic lupus erythematosus (SLE), primary Sjögren's syndrome (pSS) , systemic sclerosis (SSc), idiopathic inflammatory myopathies (IIM) and primary vasculitides, have a high risk of herpes zoster (HZ) infection. This increased susceptibility is caused by a deficient cell-mediated immune response due to the underlying disease and glucocorticoid and immunosuppressive treatments that impair the T-cell response, including conventional and unconventional synthetic disease-modifying anti-rheumatic drugs (DMARDs) and biological agents. In this context, the recent availability of a recombinant vaccine against HZ (RZV or Shingrix®), composed of recombinant VZV glycoprotein E (gE) and the AS01B adjuvant system (HZ/su), is a major progress regarding safety for immunosuppressed patients. Its effectiveness, however, has been clearly demonstrated for non-immunosuppressed patients and in selected populations of immunocompromised individuals. There are no prospective controlled studies evaluating the immunogenicity of RZV and its impact on the activity of the underlying disease, as well as its safety in patients with ARDs at high-risk for HZ. Hypothesis: RZV has a good safety profile, including with respect to underlying rheumatic disease activity, in patients with ARDs at high risk of HZ. Objectives: Primary: To assess the short-term safety profile in relation to underlying disease activity in patients with ARDs at high risk of HZ immunized with RZV compared to unvaccinated patients. Secondary: To evaluate the general safety of the vaccine in patients with ARDs at high risk of HZ immunized with RZV and non-immunosuppressed control subjects (CG); the humoral and cellular immunogenicity of RZV in patients with ARDs at high risk of HZ compared to CG; the influence of disease treatment on vaccine response; the 12-month persistence of humoral immunogenicity and incident cases of HZ. Specific studies will also be carried out to evaluate the effect of drug withdrawal (methotrexate-MTX and mycophenolate mofetil-MMF) after vaccination in increasing the immune response in patients with ARDs with controlled underlying disease.
This clinical trial is to study the safety and tolerability of a recombinant herpes zoster vaccine (LZ901) and sponsored by Beijing Luzhu Biotechnology Co., Ltd. It is a phase I, randomized, double-blind, placebo-controlled, dose escalation study in healthy people aged 50 to 70 years inclusive. The study is to protect adults against shingles (herpes zoster / varicella zoster virus(VZV)). There will be about 66 participators who will receive two-dose injection at the upper arm. LZ901 vaccine is made up of a tetramer of VZV glycoprotein E (VZV gE-Fc) and adsorbed with aluminum hydroxide adjuvant. This adjuvant can raise the immune response to a lot of antigens. It is the most widely used and safe adjuvant in various types of vaccines worldwide. In this study: 1. The participation is voluntary. 2. Before the study, participants will receive some tests for screening. If qualified, investigators will officially invite them to join this study. 3. The study vaccine is LZ901 with two different dose levels (50μg/0.5 mL, 100μg/0.5 mL). The placebo, which is saline solution, has no active drug. Participants will receive one of three as above mentioned. 4. Participants will be enrolled in one of four cohorts. If participants are enrolled in Cohorts 1 or 2, they will receive LZ901. If participants are enrolled in Cohorts 3 or 4, they will have a 2 out of 3 chance (66%) of receiving LZ901 and 1 out of 3 chance (33%) of receiving placebo. 5. In Cohort 3 and 4, the study staff and participants will not know which study treatment participants will be receiving. However, the study doctor can get this information in case of an emergency. 6. Participants will stay at the clinic for 30 minutes after each vaccination to observe if there are any uncomfortable. 7. This study will last about 8 months and will include about 8 study visits to the clinic. During this period, participants will receive a follow-up phone call and/or email by the study staff to follow the condition closely for safety, and record on diary/contact card. 8. Participants will receive some tests during the study, include safety tests such as physical examination, vital signs measurements, blood tests, urinalysis. Participants will be measured the levels of specific antibodies to see if the vaccine works well. This study is for research purposes only. Participants may not receive any direct benefits from participating in this study but have a chance to be in a study that may help others in the future.
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 14 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.
Kidney transplant recipients are at increased risk of infections, including Varicella-zoster virus (VZV) infections. Vaccination against VZV is routinely offered to all kidney transplant recipients and candidates in Denmark. In this exploratory observational study, the VZV specific immune response in kidney transplant candidates and recipients will be characterized at different time points in relation to transplantation, vaccination and infections. More knowledge on the immune reaction to transplantation, VZV vaccination and VZV infections may provide improved strategies for prevention and treatment of VZV infections in kidney transplant candidates and recipients.
The purpose of this study is to provide evidence as to whether RZV is immunogenic with an acceptable safety profile in Multiple Sclerosis patients on anti-CD20 treatment.
Background: Shingles is a painful, blistering rash caused by the same virus that causes chickenpox. Shingrix is a vaccine approved to prevent shingles in healthy adults over age 50 and in immunocompromised adults over age 18. Researchers want to learn more about how people with HIV respond to Shingrix. Objective: To learn how Shingrix affects the immune response in people with HIV. Eligibility: People aged 18 years and older with HIV. Healthy people aged 50 years or older are also needed. Design: Participants will have at least 4 clinic visits in 1 year. Participants will be screened. They will have a physical exam with blood and urine tests. At their first visit, participants will receive Shingrix as a shot in the upper arm. They will have a rectal swab; a cotton swab will be inserted into the rectum and rotated gently to collect bacteria. Participants will receive a second shot of Shingrix 2 months after the first one. They will visit the clinic again 3 and 12 months after the first shot. Participants will receive a 28-day memory tool. They will write down their symptoms between clinic visits. They will have up to 4 phone calls to talk about side effects of the shot. Participants may undergo apheresis: They will lie still while blood is drawn from a needle in one arm. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be given back through a second needle in their other arm.
To compare the efficacy and tolerability of three different doses of Pascorbin® besides standard medication with placebo and the reduction of herpes zoster-associated clinical symptoms as an add-on therapy for patients suffering from acute herpes zoster in primary care
This randomized, double-blind, placebo-controlled, non-inferiority crossover study will evaluate the Herpes Zoster Sunbit (HZ/su) vaccine in SLE patients in order to evaluate safety and immunogenicity in patients with variable baseline clinical activities, ages and immunosuppressant exposures. The investigators hypothesize that HZ/su administration will be non-inferior to placebo with respect to the risk of moderate or severe SLE flare(s) occurring within 24 weeks of receiving the first dose of the assigned treatment. In addition, the investigators hypothesize that immunogenicity of the vaccine in SLE patients will be at least 50% of levels observed in healthy subjects from prior large clinical trials.
This is a phase II study that will examine the immunogenicity of the Shingrix vaccine in patients following an allogeneic stem cell transplant.
Herpes zoster is a common disease, usually caused by the reactivation of latent varicella zoster virus from the dorsal root ganglion. Acute herpes zoster is characterized by severe pain and the appearance of vesicular skin rashes that usually heal in 2-3 weeks. One of the complications of acute herpes zoster is post-herpetic neuralgia (PHN), which is usually defined as persistent pain lasing 90 days or more from the onset of skin rash. The reported incidence of PHN ranges from between 5% to over 50%. PHN can negatively impact one's quality of life due to serious physical, psychological, functional, and social disturbances due to consequences of chronic pain. Platelet rich plasma (PRP) is an emerging treatment option for chronic pain. It is currently used predominantly for treating musculoskeletal pain conditions such as osteoarthritis and tendinopathies. However, PRP promotes the healing of nerve injury and reduces neuropathic pain, making it a potentially promising treatment option for neuropathic pain. The effect of interlaminar epidural PRP for PHN has not been studied. In this study, a case series will be performed to investigate the analgesic effect of interlaminar epidural PRP for patients with thoracic herpes zoster.
