Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Intervention/exposure

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.

Eligibility
Key inclusion criteria
* Adults greater than or equal to (>=) 18 years of age at the time of consent and as applicable, must also meet the legal age of consent in the jurisdiction in which the study is taking place
* Diagnosed with Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) according to criteria of the European Academy of Neurology/Peripheral Nerve Society (EAN/PNS) 2021, progressing or relapsing forms. CIDP diagnosis to be adjudicated by independent committee during screening period
* Adjusted Inflammatory Neuropathy Cause and Treatment (INCAT) disability score between 2 and 9 (a score of 2 has to be exclusively from leg disability)
* Fulfilling any of the following treatment conditions: a) Currently treated with oral corticosteroids (CS) less than or equal to (<=) 20 milligrams (mg)/day; or b) Currently treated with pulsed CS, and/or intravenous immunoglobulin (IVIg) or subcutaneous immunoglobulin (SCIg) and the participant is willing to discontinue no later than the run-in baseline visit; or c) Currently treated with oral CS greater than (>) 20 mg/day and the participant is willing to taper to <=20 mg/day during the run-in period; or d) Without previous treatment (treatment naive); or treatment with CS and/or IVIg or SCIg discontinued at least 3 months prior to screening (untreated)
* Active disease as determined by CIDP Disease Activity Status (CDAS) score >= 3
* Other protocol-defined inclusion criteria will apply
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
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
