About this study
Official title: Efficacy, Immunogenicity, and Safety of the Recombinant Herpes Zoster Vaccine (RZV) in Patients With Autoimmune Rheumatic Diseases Under Immunomodulators
This interventional phase IV clinical trial will evaluate the efficacy, immunogenicity and safety of the adjuvanted recombinant herpes zoster vaccine (RZV) in adults with autoimmune rheumatic diseases (ARDs) receiving immunomodulatory monotherapy. Humoral immune response will be quantified by anti-glycoprotein E (anti-gE) antibody titers. Patients will receive two doses of RZV. Outcomes include seroconversion and geometric mean titers six weeks after completion of the vaccination schedule, persistence of antibody titers at one year, and incidence of confirmed herpes zoster during follow-up.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Recombinant Zoster Vaccine (RZV)Biological
VRZ (Shingrix®) is composed of 50 μg of recombinant VZV glycoprotein E (gE) and the liposome-based AS01B (HZ/su) adjuvant system (containing 50 μg of 3-O-desacyl-4'-monophosphoryl lipid A [MPL] and 50 μg of Quillaja saponaria Molina, fraction 21 (QS21), licensed by GSK from Antigenics, a subsidiary of Agenus). Two doses of the vaccine will be administered (0.5 mL) into the deltoid muscle on days (D) 0 and D42.
| Study group | Role | What they receive |
|---|---|---|
| Immunomodulator Monotherapy | Experimental | Participants with autoimmune rheumatic diseases who are clinically stable and receiving monotherapy with hydroxychloroquine or sulfasalazine will receive two doses of the recombinant zoster vaccine (RZV, Shingrix) administered intramuscularly on Day 0 and Day 42. Immunogenicity will be evaluated through anti-glycoprotein E antibody titers at baseline, six weeks, and one year after vaccination. Safety, disease activity, and incidence of herpes zoster will be monitored throughout follow-up. Receives: Biological: Recombinant Zoster Vaccine (RZV) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Seroconversion rate of anti-glycoprotein E (anti-gE) antibodies six weeks after completion of the RZV vaccination schedule
Humoral response will be assessed by ELISA quantification of anti-glycoprotein E antibodies. Seroconversion will be defined as a fourfold or greater increase from baseline or a fourfold increase above the lower limit of quantification for participants who are seronegative at baseline. The outcome is the proportion of participants who achieve seroconversion at Day 84.
Measured: Baseline (Day 1) through day 84.
Secondary outcomes (8)
Geometric mean titers of anti-glycoprotein E antibodies six weeks after completion of the RZV vaccination schedule
Anti-glycoprotein E antibody concentrations will be measured in serum samples using an ELISA. Titers will be log-transformed and geometric mean titers will be calculated as the exponential of the mean of the log-transformed values. The outcome is the GMT at Day 84 and its change relative to baseline.
Measured: Baseline (Day 1) through day 84.
Persistence of antibody titers one year after completion of the RZV vaccination scheme
Antibody persistence will be evaluated by quantifying anti-glycoprotein E antibody concentrations using ELISA. Results will be expressed as geometric mean titers obtained from log-transformed antibody levels. Seroconversion at one year will be defined as a fourfold or greater increase relative to baseline or a fourfold increase above the assay lower limit of quantification for participants seronegative at baseline.
Measured: Day 1 (baseline) through day 84 and one year after the second dose (Day 365)
Safety of RZV vaccine in ARD patients under immunomodulators
Safety will be assessed by recording local and systemic adverse events through standardized diaries completed after each dose and confirmed during clinic visits. Events will be graded according to World Health Organization severity and CDC criteria.
Measured: Baseline (Day 1) through day 84.
Incidence of herpes zoster over one year following RZV vaccination in ARD patients under immunomodulators therapy
A suspected case of herpes zoster will be defined as (1) a new unilateral, dermatomal, rash with pain (broadly defined to include allodynia, pruritus, or other abnormal sensations) without any alternative diagnosis or (2A) or a vesicular rash suggestive of varicella zoster virus infection regardless of the distribution, and no alternative diagnosis; without any alternative diagnosis. For each suspected case, the rash will be photographed and samples will be collected from three lesions to confirm the diagnosis of HZ by real-time polymerase-chain reaction (PCR) assay. If the PCR results were indeterminate or if samples were not available, the final diagnosis will be determined by unanimous agreement among the five members of an ascertainment committee, which includes a dermatologist.
Measured: Day 42 through one year after the second dose (D365).
Disease safety (flare) - Rheumatoid Arthritis
Rheumatoid Arthritis (RA): An absolute increase in Disease Activity Score C-reactive protein (DAS28-CRP) > 1.2, or an increase > 0.6 if baseline > 3.2.
Score: 0 to 10 - higher values indicates higher disease activity.
Measured: Day 1 (baseline) through day 42 and six weeks after the second dose D84.
Disease safety (flare) - Systemic Lupus Erythematosus
Systemic Lupus Erythematosus (SLE): An increase of more than three points in the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K).
Score: 0 - No activity; 1 - 4 mild activity; > 6 high activity
Measured: Day 1 (baseline) through day 42 and six weeks after the second dose D84.
Disease safety (flare) - Ankylosing Spondylitis
Ankylosing Spondylitis (AS): An increase in Ankylosing Spondylitis Disease Activity Score (ASDAS).
Scores activity:
<1.3: Inactive disease 1.3 to <2.1: Moderate disease activity 2.1 to 3.5: High disease activity >3.5: Very high disease activity
Measured: Day 1 (baseline) through day 42 and six weeks after the second dose D84.
Disease safety (flare) - Sjögren's Syndrome
We will use the EULAR Sjögren's Syndrome Disease Activity Index (ESSDAI).
This score ranges from 0 (minimum) to 123 (maximum). Higher scores indicates greater disease activity.
Measured: Day 1 (baseline) through day 42 and six weeks after the second dose D84.
