Adult males and females, 18 to 75 years of age (inclusive) at Screening. 3. Weight range between 40 to 120 kg at Screening. 4. A diagnosis of definite or probable MMN per the European Federation of Neurological Societies (EFNS) / Peripheral Nerve Society (PNS)(EFNS/PNS) 2010 guidelines at Screening. 5.

Exclusion criteria
Exclusion criteria: 1. History or presence of significant medical/surgical condition including any acute illness or major surgery considered to be clinically significant or that could have potential impact on safety/efficacy or study procedures in the opinion of the Investigator. 2. Any coexisting conditions, which may interfere with outcome assessments, such as severe diabetic neuropathy, chronic inflammatory demyelinating polyneuropathy, inflammatory arthritis or osteoarthritis affecting the hand (among others). 3. Concurrent or previous use of rituximab. If a participant has previously used this medication, the last dose must be at least 6 months prior to Day 1. 4. Concurrent use of cyclophosphamide, mycophenolate mofetil, azathioprine, cyclosporine, corticosteroids or other. If a participant has previously used these medications, the last dose must be prior to Day 1. 5. Currently or previously on complement inhibitors, including in a clinical trial setting. 6. History of positive test results for active human immunodeficiency virus (HIV-1 or HIV-2), hepatitis B surface antigen (HBsAg), or hepatitis C virus (HCV) antibodies. Participants who have no evidence of cirrhosis, have completed a curative intent regimen for HCV, and are deemed by a gastroenterologist to have no active HCV will not be excluded. 7. Known diagnosis of systemic lupus erythematosus (SLE) or family history (defined as a parent, sibling, or child) of SLE; 8. History of active malignancy within 5 years prior to Screening, except basal cell carcinoma of the skin, curatively resected squamous cell carcinoma of the skin, cervical carcinoma in situ curatively treated or low-grade prostate adenocarcinoma for which appropriate management is observation alone. 9. Clinically significant drug or alcohol abuse in the opinion of the Investigator. 10. Participation in another clinical study of an investigational drug within 90 days or 5 half-lives of the investigational agent (whichever is longer) prior to Day 1. 11. Any other overlapping condition for which the condition or treatment of the condition may affect the study assessments or outcomes. 12. Any other condition, including mental illness or prior therapy, that in the opinion of the Investigator would make the participant unsuitable for this study, including inability to cooperate fully with the requirements of the study protocol or likelihood of noncompliance with any study requirements.
