Is this trial a fit for you?

Likely a good fit

Adults (18+) with diagnosed MMN who have ultrasound-confirmed nerve thickening and a MMN-RODS centile score of 90 or less.

Probably not a fit

Some participants may not experience meaningful benefit and could have safety risks from treatment.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This Phase 1, open-label study administers empasiprubart intravenously to adults with MMN to examine its effects on nerve thickness, muscle strength, movement, and grip ability. Participants receive the treatment over a defined period, followed by a safety follow-up of up to 15 months, with an overall involvement of about 29 months per participant. Outcomes focus on ultrasound-determined nerve morphology, functional strength, and daily-hand use. The trial is sponsored by argenx and conducted at selected clinics in Tbilisi, Georgia.

Why it matters

Potential benefit: If successful, patients with MMN could experience improvements in nerve structure and hand function that may help with everyday tasks.

How similar studies have gone: Previous studies of similar biologic approaches in MMN have shown mixed or preliminary signals; this study explores a novel agent in a Phase 1 setting.
