Brief summary
The purpose of this study was to understand whether participants could mount an immune response to SARS-CoV-2 modRNA vaccines administered either during continuous siponimod treatment or during a treatment break versus while on treatment with first-line DMTS or no current MS treatment..
Detailed description
This was a three cohort, multicenter, open-label, study of 60 planned (optionally up to 90) multiple sclerosis (MS) patients who were on treatment with siponimod or a first-line disease modifying therapy (DMT) or without MS treatment planning to undergo a SARS-CoV-2 modRNA vaccination as part of clinical routine. * The first cohort enrolled participants who did not interrupt their siponimod therapy for the purpose of a SARS-CoV-2 modRNA vaccination. * The second cohort enrolled participants who interrupted their siponimod therapy for the purpose of a SARS-CoV-2 modRNA vaccination for approximately 2-3 months * The third cohort enrollled participants who received modRNA vaccination while on treatment with the following first-line DMTs (dimethylfumarate, glatirameracetate, interferons, teriflunomide) or no current treatment in clinical routine. The study consists of a screening period, vaccination period and investigational period. During the screening period of up to one month eligibility and SARS-CoV-2 antibodies at baseline were assessed. The 3-4 week vaccination period started with first dose of modRNA vaccine on Day 1 and ended with second dose of modRNA vaccine 3-4 weeks after first dose depending on EU SmPC. The investigational period lasted 12 months, during which blood samples for primary and secondary endpoint analyses were drawn at 1 week (Visit 1), 1 Month (Visit 2) and 6 months (Visit 3) after completion of vaccination (i.e. second dose of vaccine). 12 months after completion of vaccination a COVID-19 follow-up call was scheduled. As patients were treated according to clinical routine, the start of treatment was defined as the date the informed consent was signed. Booster vaccinations were allowed as per local regulations, physician's discretion and as part of clinical routine. This booster may have been any type of SARS-CoV2 vaccine and introduction of a treatment break for the purpose of booster vaccination was at the discretion of the treating physician or patient for all three cohorts. In case of booster vaccinations an additional blood sample was collected 1 month after the booster vaccination (booster Visit). The planned study duration for each participant was 56-64 weeks, depending on the length of the screening period. The study investigated the development of functional anti-SARS-CoV-2 antibodies and T-cell titers for six months after the participants' vaccination.
Interventions
taken orally once per day (dose depends on CYP2C9 genotype)
DMTs: Dimethylfumarate, glatirameracetate, interferon, teriflunomode according to respective SmPC
Administerd according to the respective EU SmPC at the discretion of the treating physician independent of AMA-VACC. If suggested by local regulations and performed as part of clinical routine any type of booster/refresher vaccination (e.g. mRNA, vector, peptide) was allowed in this study.
