Intervention/exposure
Study type
Interventional(has expanded access)
Description of intervention(s) / exposure
Treatment: Drugs - Nipocalimab
Treatment: Drugs - Placebo

Experimental: Nipocalimab - Participants in Stage A (Open-label) will receive a loading dose of nipocalimab (Dose 1) intravenous (IV) infusion on Day 1, followed by nipocalimab (Dose 2) IV infusion once every 2 weeks (q2w) from Week 2 to Week 12. Participants who demonstrate evidence of clinical improvement in Stage A (responders) will enter Stage B (Double-blind) and receive nipocalimab (Dose 2) IV infusion q2w starting on Day 1 up to Week 52. After completion of Stage B or discontinuation from Stage B due to relapse, participants will have the option to enter the open label extension (OLE) phase and receive nipocalimab (Dose 2) IV infusion q2w starting on OLE Day 1 until 2 years after marketing authorization in a participant's local country or until nipocalimab becomes available commercially or via other continued access program, whichever comes first.

Placebo comparator: Placebo - Participants receiving nipocalimab in Stage A and who demonstrate evidence of clinical improvement in Stage A (responders) will enter Stage B (Double-blind) and receive placebo IV infusion q2w starting on Day 1 up to Week 52. After completion of Stage B or discontinuation from Stage B due to relapse, participants will have the option to enter the open label extension (OLE) phase and receive nipocalimab (Dose 2) IV infusion q2w starting on OLE Day 1 until 2 years after marketing authorization in a participant's local country or until nipocalimab becomes available commercially or via other continued access program, whichever comes first.


Treatment: Drugs: Nipocalimab
Nipocalimab will be administered intravenously.

Treatment: Drugs: Placebo

Can healthy volunteers participate?
No
Key exclusion criteria
* Has a history of severe and/or uncontrolled hepatic (example, viral/alcoholic/autoimmune hepatitis/cirrhosis and/or metabolic liver disease), gastrointestinal, renal, pulmonary, cardiovascular, psychiatric, neurological or musculoskeletal disorder, hypertension and/or any other medical or uncontrolled autoimmune disorder(s) (example, diabetes mellitus) or clinically significant abnormalities in screening laboratory that, might interfere with the participants full participation in the study, or might jeopardize the safety of the participant or the validity of the study results
* Pure sensory CIDP or chronic immune sensory polyradiculopathy (CISP) (EAN/PNS definition)
* Any other disease that could better explain the participant's signs and symptoms, such as significant persisting neurological deficits from stroke or central nervous system (CNS) trauma or peripheral neuropathy from another cause such as connective tissue disease or systemic lupus erythematosus
* Polyneuropathy of other causes, including the following: Multifocal motor neuropathy (MMN); Monoclonal gammopathy of uncertain significance with antimyelin associated glycoprotein (anti-MAG) immunoglobulin M (IgM) antibodies; Hereditary motor neuropathy; Hereditary neuropathy with liability to pressure palsies (HNPP); Polyneuropathy, organomegaly, endocrinopathy, monoclonal protein and skin change syndromes; Lumbosacral radiculoplexus neuropathy; Polyneuropathy most likely due to diabetes mellitus; Polyneuropathy most likely due to systemic illnesses; Drug- or toxin-induced polyneuropathy Note: A concomitant polyneuropathy of other causes (example, a mild, stable diabetic polyneuropathy) is not necessarily exclusionary if chronic inflammatory demyelinating polyneuropathy (CIDP) is confirmed as the main diagnosis, as determined by the investigator and confirmed by the adjudication committee
* Has known allergies, hypersensitivity, or intolerance to nipocalimab or its excipients
