A Study to Assess the Effect of Empasiprubart on Nerve Morphology by Ultrasound in Adults With Multifocal Motor Neuropathy

Summary

The main purpose of the study is to evaluate empasiprubart use in adults living with Multifocal Motor Neuropathy (MMN). The researchers will evaluate the effect of empasiprubart on the thickness of the nerves, muscle strength, movement, and on the potential improvement of grip strength of the participants in handling objects. The study consists of an open-label treatment period where all participants will receive empasiprubart intravenously (IV). After the last dose of empasiprubart participants will enter a safety follow-up period for up to 15 months. The total study duration for each participant will be approximately 29 months.
