About
The purpose of HZ-REUMA study is explore vaccine response and protection against shingles (herpes zoster, HZ) after vaccination with two doses of Shingrix in immunosuppressed patients with inflammatory rheumatic diseases (IRD) compared to immunocompetent patients with IRD (controls).
Hypothesis:
The immunological disturbance as part of the rheumatic disease in combination with different immunomodulating treatments may impair vaccine response to non-live HZ vaccine (Shingrix) and thereby lead to an insufficient protection against infection.
Primary objective (outcome)
The impact of modern anti-rheumatic treatments including synthetic disease modifying anti-rheumatic drugs (DMARDs) such as methotrexate and different biological treatments (anti-TNF, anti IL6r, anti-IL12/23/17, anti-CD20, anti-BlyS, anti-INFERON treatment, or targeted DMARDs (JAK-inhibitors) on antibody response elicited by two doses of subunit vaccine against herpes zoster (HZ) administrated 1-2 months apart in patients with IRD.
Secondary outcomes
The numbers and frequency of antigen specific CD4 2+ T cells expressing ≥2 or more activation markers (TNFalpha, INF-gama, interleukin-2 or CD40ligand)
Long-term immunogenicity of two doses of Shingrix in immunosuppressed patients with IRD measured 3 and 5 after vaccination
the tolerability of the vaccine, the impact on existing rheumatic disease, and possible association with onset of new autoimmune diseases
if vaccination against herpes zoster protects against infections in patients with inflammatory rheumatic diseases
Study Population Adult patients (18 years and older) with a clinically diagnosed inflammatory rheumatic disease and regularly followed at Skåne University Hospital, section for rheumatology in Lund/Malmö, Sweden are eligible for the study and will be offered vaccination free of charge. Control group comprises adult individuals with known inflammatory rheumatic disease without immunosuppressive treatment except for low dose prednisone (max 5 mg daily) .

Full description
Patients with inflammatory rheumatic diseases (IRD) such as rheumatoid arthritis (RA), SLE, spondyloarthropathies, systemic vasculitis or systemic sclerosis (Granulomatosis with polyangiitis, GPA; Eosinophilic granulomatosis with polyangiitis, EGPA, Giant Cell Arteritis, GCA), systemic sclerosis or other inflammatory systemic disease) have an increased morbidity and mortality in infections. These infections include the numerous vaccine-preventable diseases such as herpes zoster (HZ). Vaccination is a cost-effective measure to prevent an infection. However, several studies have reported an impaired response to common vaccinations among immunosuppressive patients with IRD. The underlying mechanisms are not entirely known. The Centre for Disease Control (CDC) Advisory Committee for Immunization Practice (ACIP) as well as the European League Against Rheumatism (EULAR) and Swedish authorities (The Public Health Agency of Sweden) recommend vaccination against HZ to the risk groups. Majority of patients with IRD are treated with potent immunosuppressive drugs and thereby belong to the target group for HZ vaccine. Data on the immunogenicity, tolerability of a non-live, subunit vaccine against HZ (Shingrix) among immunosuppressed patients with IRD is limited. The overall aim of this research project is to study antibody and T cells response and tolerability of two doses of subunit HZ vaccine (Shingrix) in immunosuppressed patients with IRD compared to IRD patients without active immunosuppressive treatment (with exception for prednisolone orally in a maximal daily dose of 5 mg).
Hypothesis The immunological disturbance as part of the rheumatic disease in combination with different immunomodulating treatments may impair antibody and T cells vaccine response but vaccination is still expected to generate a "satisfactory immune response".
Main objective (outcome)
To study:
Safety assessments and safety reporting -At vaccination (visit 1 and 2) when the first and second vaccine doses are administrated each participant will receive oral information on the common adverse events (AE), adverse drug reactions (ADR) and serious adverse events (SAE). AEs/ADRs will be assessed and reported using the GSK global safety document.
Safety Reporting Institution/Investigator is solely responsible for reporting all Adverse Events and Serious Adverse Events to regulatory authorities, investigators, IRBs or IECs, and GSK, as applicable, in accordance with national regulations in Sweden where the study is conducting.
Severity of Event
Collection and Reporting of AEs & SAEs Study patients will be instructed to contact the study staff if any serious or unexpected adverse event occurs. Reported AE's will be recorded in detail in an AE case report form. Adverse events will be identified with patients during study visits. Any adverse events will be discussed with the PI and will be reviewed to determine whether a change in protocol is necessary.
All adverse events and serious adverse events should be recorded on the Adverse Event Log, Serious Adverse Event Log, and in Data Management system, within 24 hours.
Fatal and Life Threatening SAEs within 24 hours of the investigator's observation or awareness of the event.
All other serious (non-fatal/non-life threatening) events within 4 calendar days of the investigator's observation or awareness of the event.
All pregnancy events within 4 calendar days of the investigator's awareness of the event. All pIMDS or exacerbation of pIMDS events within 7 calendar days of the investigator's observation or awareness of the event.
In addition, each participant is provided with a written questionnaire on the possible effects from the vaccination (AE, ADR or SAE) with instructions how to record them and a telephone number to the research nurse in case of more serious side effects or emergency department (life-threatening effects). In case of reactivation of HZ infection all participants are encouraged to contact the research nurse for an extra visit för VZV PCR or serological response and anti-viral treatment according to algorithm.
PI will report AEs/SAEs to the authorities, IRBs/IECs as appropriate. AEs will be graded as mild, moderate, severe and life threatening. All SAEs, pIMDs will be reported to GSK within 24 hours to the GSK Safety mailbox: ogm28723@gsk.com.
All ADRs that are both serious and unexpected are subject to expedited reporting by the PI. All serious effects will be reported to the authorities as required i.e. effects no later than 15 calendar days after first knowledge (serious) and as soon as possible but no later than 7 calendar days after first knowledge (lethal/life-threatening adverse/unexpected effects. The GSK AE case report form will be used for reporting ARDs and SAEs.
Additional safety endpoints: an exacerbation of pre-existing rheumatic disease accessed by the rheumatologist/ PI/sub-investigators, or an onset of other auto-immune conditions (see list) requires assessment by the PI and will be reported, recorded in details and followed until resolved.

Study Design and Methods
At vaccination (visit 1) the physical examination is performed by a rheumatologist and data on disease and treatment characteristics, anti-rheumatic treatments and other concomitant treatments including previous vaccinations and history of varicella or HZ (study questionnaire), co-morbidity (Charlson Comorbidity Index (CCI), smoking habits (questionnaire), physical function (health assessment questionnaire, HAQ;), EQ5D are collected.
-Patients reported outcome (HAQ, EQMD) are registered in the Swedish rheumatology registry (SRQ) which is a part of a routine care.
Blood Sampling
Blood will be collected pre-vaccination, 4-6 weeks post-dose 2, thereafter 3 years, and 5 years (see schedule of activities).
Statistical Plan and data analysis The study population comprise at least 240 individuals who have received two vaccine doses, whose blood samples have been collected before vaccination and the second vaccine dose. Of these, 190 are patients and 50 controls (patients not receiving any immunosuppressive treatment). In order to ensure the number of participants who fulfil these criteria approximately 10% additional participants (both patients and controls) will be recruited.
Patient groups will be further stratified in two groups, according to either immunosuppressive treatment or diagnosis . Geometric mean antibody levels, GML after vaccination compared to pre-vaccination GML. The percentage of responders (defined as ≥ 4-fold increase in pre-vaccination antibody levels) are assumed to be 99,99% and 80% in control respectively. In order to compare % responders in controls (n=50) and patient group (n=190) with a planned sample size we will have an 80% power to detect 20% unit difference with 5% significance and two sided hypothesis.
Power calculation Two-sided confidence interval (%) 95 Number of exposed immunosuppressed patients 190 Risk of disease among exposed (%) 80 Number of non-exposed 50 Risk of disease among non-exposed (%) 99 Risk ratio detected 0.81
Power based on:
Normal approximation 90.78% Normal approximation with continuity correction 86.38% Percentage of participants seropositivity and seroconversion (after two vaccine doses) will be calculated and compared between two groups. GML before and after will be compared between the groups.
In addition, statistical comparation will be performed with patients receiving only one vaccine dose using appropriate statistical analysis (depending on the number of such cases).
Details around stratification of patients:
Significance Results from this project will be used to support recommendations on vaccination against HZ in immunosuppressed patients known to be at an increased risk of HZ and its complications.
