Open Actively Recruiting

COVID-19 Booster Vaccine in Autoimmune Disease Non-Responders

About

Brief Summary

This is a randomized, multi-site, adaptive, open-label clinical trial comparing the immune response to different additional doses of COVID-19 vaccine in participants with autoimmune disease requiring IS medications. All study participants will have negative serologic or suboptimal responses (defined as a Roche Elecsys® Anti-SARS-CoV-2 S result ≤200 U/mL) or a low immune response (defined as a Roche Elecsys® Anti-SARS-CoV-2 S result >200 U/ml and ≤2500 U/mL) to their previous doses of COVID-19 vaccine.

The study will focus on 5 autoimmune diseases in adults: - Systemic Lupus Erythematosus (SLE) - Rheumatoid Arthritis (RA) - Multiple Sclerosis (MS) - Systemic Sclerosis (SSc), and - Pemphigus. This study will focus on 4 autoimmune diseases in pediatric participants: - Systemic Lupus Erythematosus (SLE) - Juvenile Idiopathic Arthritis (JIA) - Pediatric-Onset Multiple Sclerosis (POMS) - Juvenile Dermatomyositis (JDM)

General Adult Inclusion Criteria:

  • Willing and able to sign informed consent 2. Documented full COVID-19 vaccination (CDC card or documentation in medical records) that was completed at least 4 weeks prior and no more than 52 weeks prior to the Stage 1 Screening visit, or if participating in Stage 2, no more than 48 weeks prior to the Stage 2 Screening visit.

General Exclusion Criteria 2. History of severe allergic reaction to the initial COVID-19

vaccine regimen, to any component of any of the COVID-19 vaccines, or to polyethylene glycol (PEG). 3. New diagnosis of malignancy that will require chemotherapy or immunotherapy, or ongoing treatment for a malignancy with chemotherapy or immunotherapy. 4. Active disease (per the Investigator's decision) resulting in inability to hold the IS therapy in the MMF/MPA or MTX arms of the study. a. The potential impact of temporarily holding medication for participants with a recent mild disease flare within 4 weeks should be carefully considered. 5. Active disease during the Screening period resulting in:

  • An increase/addition of any IS medications, or
  • A suggestion of MS relapse per the investigator. 6. Recent or current SARS-CoV-2 infection defined as:
  • Documented SARS-CoV-2 infection in the past 30 days (from the day the participant is diagnosed by positive test to Screening).

Participants with active, ongoing chronic infections. Note: Participants are permitted to be on chronic prophylactic antimicrobial therapy. Adults with evidence of HIV, Hepatitis B indicated by surface antigen, and Hepatitis C indicated by anti-hepatitis C antibody positivity will be excluded. If an adult is negative for Hepatitis C viral load at Screening, he/she will be eligible to participate. 10. Participants with common variable immunodeficiency disease, as well as any participants currently receiving immune globulin replacement therapy. Note: Pediatric participants on IVIG therapeutically may enter the study provided they have sufficiently quiet disease that they can withhold their IVIG from 8 weeks prior to the Screening visit through 4 weeks after vaccination. 11. Participants who received licensed or investigational monoclonal antibodies or plasma products directed against SARS-CoV-2 within 30 days of Screening. 12. Participants who have received any live vaccines within 2 months of the anticipated study vaccine dose or who will have need of a live vaccine at any time during the study. 13. Currently pregnant or breastfeeding (For pediatric participants postmenarchal females must have a negative urine pregnancy test at Screening). 15. Hemoglobin (Hgb) <8.0 g/dL (80 g/L) 16. Past or current medical problems or findings from physical examination or laboratory testing that are not listed above, which, in the opinion of the investigator, may pose additional risks from participation in the study, may interfere with the participant's ability to comply with study requirements or that may impact the quality or interpretation of the data obtained from the study. 17. Other investigational chemical agent within 30 days or other investigational biologic agent within 8 weeks or 5 half-lives (whichever is longer) of Screening. 18. Concurrent treatment with cyclophosphamide. Adult participants taking cladribine, alemtuzumab, or mitoxantrone will also be excluded. 19. Participants currently on any type of dialysis, or who have received a solid organ transplant. 20. Prisoners or participants who are compulsorily detained (involuntarily incarcerated) for treatment of either a psychiatric or physical (e.g., infectious disease) illness. 21.
