Brief Summary:
The main purpose of this study is to evaluate the safety and efficacy of nipocalimab compared to placebo in delaying relapse in adults with chronic inflammatory demyelinating polyneuropathy (CIDP) who initially respond to nipocalimab in Stage A.

CIDP is a rare, chronic autoimmune disease of the peripheral nervous system characterized by progressive weakness and impaired sensation. Nipocalimab (also referred to as JNJ-80202135 or M281) is a fully human aglycosylated immunoglobulin (Ig)G1 monoclonal antibody (mAb) designed to selectively bind, saturate, and block the IgG binding site on the endogenous neonatal Fc receptor. The study will consist of the following periods: (a) identification of participants with active CIDP (including screening [up to 4 weeks] and run-in [up to 12 weeks]); (b) open-label treatment with nipocalimab (Stage A) (12 weeks); (c) double-blind, placebo-controlled, randomized withdrawal (Stage B) (up to 52 weeks); and (d) an open-label extension (OLE) (until to 2 years after marketing authorization in the participant's local country or until nipocalimab becomes available commercially or via other continued access program, whichever comes first). Participants who discontinue treatment and intend to withdraw from the study at any point during the treatment periods (Stage A, Stage B, or the OLE) will be requested to enter an 8-weeks follow-up after the last dose of study intervention. Efficacy, safety, pharmacokinetics (PK), immunogenicity, and biomarker evaluations will be assessed.

The I-RODS comprises of 24 items representing common daily activities that address upper and lower limb disability and range in difficulty from very easy to very difficult. Lower scores indicate greater activity and social participation limitations.
- Stage A: Change from Baseline Over Time in Mean Grip Strength (Dominant Hand) [ Time Frame: Baseline to 12 weeks ]Change from Stage A baseline over time in mean grip strength (dominant hand) will be reported. Grip Strength is a quantifiable, objective performance outcome measure of hand strength, which can be measured using various devices (for example, Martin Vigorimeter and Jamar Dynamometer).

- Stage B: Change from Baseline Over Time in Mean Grip Strength (Non-Dominant Hand) [ Time Frame: Up to 52 weeks ]Change from Stage B baseline over time in mean grip strength (non-dominant hand) will be reported. Grip Strength is a quantifiable, objective performance outcome measure of hand strength, which can be measured using various devices (for example, Martin Vigorimeter and Jamar Dynamometer).
- Stage B: Number of Participants with Binary Response Endpoint Satisfying all 4 Conditions: a) An Improved Adjusted INCAT Disability Score Compared to Baseline; b) Not Relapsing; c) Not Switching to SoC; d) Not Discontinuing Treatment [ Time Frame: Up to 52 weeks ]Number of participants with Binary response endpoint satisfying all 4 conditions: a) an improved adjusted INCAT Disability Score compared to Stage B baseline; b) not relapsing; c) not switching to SoC; d) not discontinuing treatment, will be reported.
