Study Endpoints
Primary Endpoints
The number of adverse events in drug versus placebo groups.
From baseline to the end of study, up to 20 weeks.

Establish the safety and tolerability of nasal foralumab dosing in subjects as a percentage of drug and placebo groups who experience adverse events.

Assessment of microglial function via PET scan using the ligand [18F]PBR06
From baseline to end of study, up to 20 weeks.

The ligand \[18F\]PBR06 provides a quantification of microglial activation during a PET scan. The investigatorshope to use this tracer at the start and end of the study to examine how the use of Foralumab may affect microglial function.

Measure the effect of foralumab on the ratio of CD4/CD8 memory/naïve T cells biomarkers in blood
From baseline to the end of treatment, up to 12 weeks.
