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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Recombinant zoster vaccine
Eligible patients were randomized in a 1:1 ratio to recombinant zoster vaccine/placebo on the background of standard of care (SOC).
Participants received two intramuscular doses of the vaccine 2 months apart.
|
Recombinant zoster vaccine (RZV) is indicated for prevention of herpes zoster in adults aged ≥ 50 years old.
RZV contains a varicella zoster virus glycoprotein E antigen and the AS01B adjuvant system.
|
Placebo Comparator: Placebo
Eligible patients were randomized in a 1:1 ratio to recombinant zoster vaccine/placebo on the background of standard of care (SOC).
Participants received two intramuscular doses of the placebo (sterilized water) 2 months apart.
