Covid19 Rheumatic Diseases Rheumatoid Arthritis SLE | Biological: Moderna COVID-19 vaccine | Phase 3 |
The purpose of this study is to evaluate the safety, local reactions (reactogenicity), capacity to form antibodies against the coronavirus (immunogenicity) and long-term persistence of those antibodies following two doses of a Health Canada approved RNA-based COVID-19 vaccine in patients with rheumatic diseases.
Two doses from the Moderna vaccine will be administered intramuscularly. The time between dose 1 and dose 2 of the vaccine will be 28 days.
This research study will recruit 220 participants (165 patients and 55 healthy controls), men and women, aged 18 years or older.

Biological: Moderna COVID-19 vaccine
Two doses from the Moderna vaccine will be administered intramuscularly. The time between dose 1 and dose 2 of the vaccine will be 28 days. |
- Frequency and grade of each solicited local and systemic adverse events (AEs) [ Time Frame: during a 7-day follow-up period post each vaccination ]
- Frequency and grade of any unsolicited AEs (including 'significant disease flares'*) [ Time Frame: during the 28-day follow-up period post-each vaccine dose. ]* 'Significant' disease flares: defined as worsening of clinical disease activity documented by the treating physician and requiring intensification of therapy.
- Geometric mean titer (GMT) of antibody [ Time Frame: at Day 57 ]
- Percentage of patients who seroconverted [ Time Frame: baseline and Day 57 ]defined as a 4-fold increase in antibody titer
- Geometric mean fold rise (GMFR) in IgG titer [ Time Frame: baseline and Day 57 ]
- Geometric mean titer (GMT) of antibody [ Time Frame: Day 28 ]post-first vaccine dose
- Geometric mean titer (GMT) of neutralizing antibody [ Time Frame: Day 57 ]
- CD4 and CD8 T cell responses [ Time Frame: baseline, Day 57 ]percent of CD4 and CD8 T cells that produce IFNγ following exposure to overlapping peptide pool representing the vaccine-encoded receptor binding domain (RBD).
- Effect of age on Geometric mean titer (GMT) in RA patients [ Time Frame: baseline, Day 57 ]Will be assessed by comparing RA treated with JAKs versus biologics versus RTX in age adjusted models.
- Geometric mean titer (GMT) in RA versus age-matched controls [ Time Frame: baseline, Day 57 ]Will be assessed by comparing RA versus HC in age adjusted models.
- Geometric mean titer (GMT) [ Time Frame: baseline, Month 6 and Month 12 ]
- Percentage of patients who seroconverted [ Time Frame: baseline, Day 57 ]defined as a 4-fold increase in neutralizing antibody titer
- Geometric mean fold rise (GMFR) of neutralizing antibody titer [ Time Frame: baseline, Day 57 ]
- Effect of treatment on Geometric mean titer (GMT) in RA patients [ Time Frame: baseline, Day 57 ]Will be assessed by comparing RA treated with JAKs versus biologics versus RTX in age adjusted models.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | Yes |
Inclusion Criteria (all of the following):
- Adults ages 18 years and older;
-
For the cases, established diagnosis of:
- RA done by a rheumatologist according to the 2010 American College of Rheumatology (ACR) /European League Against Rheumatism (EULAR) criteria, OR
- SLE done by a rheumatologist according to the 1997 revised ACR criteria and/or the 2013 SLICC lupus classification criteria and/or the 2019 EULAR/ACR criteria;
- For the cases, stable treatment (≥3 months prior to enrollment for biologics/small molecules and MMF; >3 weeks of a specific dose in case of steroids);
- For the controls, people without a diagnosis of a chronic rheumatic disease who can have comorbidities as in patients with rheumatic diseases;
- Able to comprehend the investigational nature of the protocol and provide informed consent;
- Male or non-pregnant female;
- Women of childbearing potential must agree to use at least one acceptable primary form of contraception.
Exclusion Criteria (any of the following):
- Positive pregnancy test either at screening or just prior to each vaccine administration.
- Any medical disease or condition that, in the opinion of the site Principal Investigator (PI) or appropriate sub-investigator, precludes study participation.
- Acute illness, as determined by the site PI or appropriate sub-investigator, with or without fever [oral temperature >38.0°C (100.40F)] within 72 hours prior to each vaccination.
- Diagnosis of hepatitis B, hepatitis C virus, or human immunodeficiency virus (HIV).
- History of hypersensitivity or severe allergic reaction (e.g., anaphylaxis, generalized urticaria, angioedema, other significant reaction) to any previous licensed or unlicensed vaccines.
- Participation in another clinical trial or plan to do so during the study. If a patient was on a drug trial, recruitment could occur following 2 half-lives of the study drug.
- Vaccines within the 2 weeks prior to any dose of COVID-19 vaccine or until 30 days after any dose of COVID-19 vaccine.
- Lactating female.
- Immunoglobulin therapy or blood products within the past month.
- Prior diagnosis of COVID-19 in the past 3 months.
- Planned changes in baseline drug treatments (except prednisone) for rheumatic diseases prior to D57.
- For patients required to be on cohort 8: Planned reduction of prednisone dose below 10 mg prior to D21.
