A Multicenter Study to Assess Response to COVID-19 Vaccine in Multiple Sclerosis Participants Treated With Ofatumumab

Completed

• Conditions: Relapsing Multiple Sclerosis
• Interventions: Other: Ofatumumab; Other: Covid-19 vaccine

• Registration Number: NCT04847596
• Lead Sponsor: Novartis Pharmaceuticals

Brief Summary

This is a single arm, pilot multicenter prospective study in up to 22 participants with relapsing multiple sclerosis.

Arm && Interventions

Group	Intervention	Description
participants with RMS treated with ofatumumab	Covid-19 vaccine	Relapsing MS participants receiving a full course (two doses) of a COVID-19 mRNA vaccine after starting ofatumumab 20 mg subcutaneous treatment
participants with RMS treated with ofatumumab	Ofatumumab	Relapsing MS participants receiving a full course (two doses) of a COVID-19 mRNA vaccine after starting ofatumumab 20 mg subcutaneous treatment

Primary Outcome Measures

Name	Time	Method
Proportion of participants achieving immune response - immune assay No. 1	14 days after full course vaccination (two doses)	Achieving immune response as defined by a positive SARS-CoV-2 qualitative IgG antibody assay. (yes/no)

Secondary Outcome Measures

Name	Time	Method
Proportion of participants achieving immune response - immune assay No. 2	90 days post assay 1	Achieving immune response as defined by a positive SARS-CoV-2 qualitative IgG antibody assay 90 days after assay No. 1 (yes/no)
Adverse events/serious adverse events	120 days after full course vaccination	An adverse event (AE) is any untoward medical occurrence (e.g. any unfavorable and unintended sign \[including abnormal laboratory findings\], symptom or disease) in a clinical investigation participant after providing written informed consent for participation in the study.; Therefore, an AE may or may not be temporally or causally associated with the use of a medicinal (investigational) product.
