Recombinant Zoster Vaccine in Stable SLE Patients

October 25, 2022 updated by: RenJi Hospital

Efficacy and Safety of Recombinant Zoster Vaccine in Stable SLE Patients(Vtrial)

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.

Detailed Description

Systemic lupus erythematosus (SLE) is a chronic systemic autoimmune disease that requires long-term corticosteroid and/or immunosuppressive agents. Thus lupus patients are immunocompromised patients, and the incidence of herpes zoster is higher than general population (asian population 32.5-91.4/1000 person-years vs general population 2.58-4.89/1000 person-years). Patients with active SLE are more susceptible because they require stronger immunosuppressive therapy. However, even mild or even stable lupus patients are highly susceptible, and they account for about two-thirds of the events. In addition, herpes zoster may trigger lupus flare. A case-control study showed a close correlation between herpes zoster reactivation and the diagnosis of lupus, and our previous studies indicated that recent 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 herpes zoster could reduce the risk of zoster reactivation in lupus patients is to be explored in this study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.
