Filter by:Objective: To investigate whether replacement of MMF/MPA by everolimus in kidney transplant recipients results in superior immunogenicity of COVID-19 vaccination as measured by neutralizing antibody titer against the Omicron XBB.1.5 strain. Trial design: Multicentre, open-label randomized controlled clinical trial, for a duration of at least 10 weeks with an optional extension to 18 weeks. Trial population: Kidney transplant recipients, 18 years or older, who are at least 6 months after transplantation, with a functioning kidney transplant, using MMF/MPA in combination with at least one other immunosuppressant including a calcineurin inhibitor (CNI), with at least 3 previous COVID-19 vaccinations (=basic COVID-19 immunisation). Interventions: Patients will be randomized into one of two equally sized groups, with either continuation of their current immunosuppressive regimen including MMF/MPA or replacement of MMF/MPA by everolimus during at least six weeks before until four weeks after the last vaccination. Patients will receive a repeated COVID-19 vaccination with the monovalent Omicron XBB.1.5 vaccine, 28 days thereafter they can opt to also receive two herpes zoster vaccinations with the Recombinant Zoster Vaccine (RZV) with an interval between the first and second dose of 28 days. Main trial endpoints: The neutralizing antibody titer against the Omicron XBB.1.5. strain 28 days after monovalent Omicron XBB.1.5 COVID-19 vaccination in patients continuing MMF/MPA compared to patients who switched to everolimus. Secondary trial endpoints: - SARS-CoV-2 specific anti-S1 antibody level at 28 and 56 days after COVID-19 vaccination - Varicella zoster specific anti-gE antibody level 28 days after 1st and 2nd herpes zoster vaccination - SARS-CoV-2 specific T-cell response 28 days after COVID-19 vaccination - Varicella zoster specific T-cell response 28 days after 2nd herpes zoster vaccination - Safety in terms of incidence of acute rejection, kidney function decline, SAEs, AESIs and solicited local and systemic AEs after COVID-19 and herpes zoster vaccination
The purpose of this study is to compare the immunogenicity and safety of recombinant zoster vaccine according to CD4+ T-cell count and age in people living with HIV, and to provide evidence to guide immunization of people living with HIV.
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.
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.
The purposes of the study are to evaluate the immunogenicity and safety of different dose levels of recombinant herpes zoster vaccine (CHO Cells) with 2 doses at 2-month intervals in healthy subjects aged 30 years and older.
The goal of this clinical trial is to evaluate the lot-to-lot consistency, immunogenicity, and safety of live attenuated varicella vaccine manufactured by Beijing Institute of Biological Products Co., Ltd in healthy children.
The purpose of this postmarketing commitment safety study is to evaluate the real-world safety of HZ/su vaccine during pregnancy in immunodeficient or immunosuppressed adult pregnant women between 18 and 49 years of age in the United States. The primary outcome of interest is major congenital malformations (MCMs).
The goal of this clinical trail is to demonstrate the non-inferiority of recombinant human interferon α-2b gel (ZK-A03) after changing the manufacturer of the active ingredient in patients with herpes zoster. This double-blind study will enroll approximately 368 adult patients with herpes zoster in China. Eligible patients will be assigned randomly at a 1:1 ratio. For each patient who is included, treatment may last up to 10 days. During the study, subjects will be treated with recombinant human interferon α-2b gel (either before or after the alteration of the active ingredient manufacturer), at a frequency of four times a day, together with a background therapy of valaciclovir hydrochloride.
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.
Local used high molecular weight Hyaluronan (HA) with high viscosity has a variety of receptors in the human body, including CD44, LYVE-1, RHAMM, HARE, Siglec-9, TLR2, CEMIP and TMEM2. Intra-articular local injection of HA has a certain degree of analgesic effect. Local injection of HA into the nerve trunk directed by ultrasound was used for the treatment of neuropathic pain. It was reported that the analgesic effect of HA is regulated by TRPV1 ion channels. This study hypothesizes that hyaluronidase cleaves HA to generate low molecular weight HA fragments HA35 with good tissue permeability, which may bind to a variety of HA receptors on the cell surface within the tissues and produce a broad-spectrum analgesic effect. In this study, 35kDa Hyaluronan fragment HA35 was prepared by mixing hyaluronidase PH20 injection and high molecular weight Hyaluronan (HA) injection at room temperature for 20 minutes. In this study, hyaluronidase injection and Hyaluronan injection were off-label used to conduct an investigator-initiated study (IIT or IIS) for the treatment of herpes zoster and shoulder, neck, back and temporal pain.
