Brief Summary:
This study aimed to understand whether patients with relapsing multiple sclerosis (RMS) can mount an immune response to SARS-CoV-2 mRNA vaccines (initial vaccinations or booster vaccines) when vaccinated either before initiation of ofatumumab treatment or at least 4 weeks after commencing ofatumumab treatment.
Detailed Description:
This was a four cohort, multicenter, open-label, prospective study of 34 (optionally up to 60) patients who had relapsing multiple sclerosis (RMS) planning to undergo a SARS-CoV-2 mRNA vaccination (initial vaccinations or booster vaccines) as part of clinical routine. The maximal duration of the study for an individual patient was 22 months.
* The first cohort was RMS patients receiving SARS-CoV-2 mRNA vaccine (initial vaccinations or booster vaccines) as part of clinical routine prior to starting ofatumumab treatment.
* The second cohort was participants receiving SARS-CoV-2 mRNA vaccine (initial vaccinations or booster vaccines) as part of clinical routine while already stable on ofatumumab treatment for at least 4 weeks (since first dose).
Cohort 1a - Patients received first SARS-CoV-2 vaccination within the study prior to starting ofatumumab treatment.
Cohort 1b - Patients had already completed initial vaccination cycle and received a booster vaccine within the study prior to starting ofatumumab treatment.
Cohort 2a - Patients who received their first SARS-CoV-2 vaccination within the study while already stable on ofatumumab treatment for at least 4 weeks (since the first dose).
Cohort 2b - Patients who had already completed their initial vaccination cycle and received a booster vaccine within the study while already stable on ofatumumab treatment for at least 4 weeks (since the first dose).
Development of SARS-CoV-2 specific T-cells and functional anti-SARS-CoV-2 antibodies were investigated for up to 18 months after the participants' vaccination.
