Detailed Description
IIM is considered as a group of rare diseases that is characterized by common features of insidious painless, proximal skeletal muscle weakness, low endurance, and elevated serum muscle enzyme levels.
Due to muscle weakness and progressive muscular atrophy, decreasing endurance, internal organ involvement (mainly given the pulmonary, gastrointestinal and cardiac manifestations) and limited therapeutic options, IIM often leads to physical disability and decreased quality of life.
Nipocalimab is a fully human aglycosylated immunoglobulin G1 (IgG1) monoclonal antibody (mAb) designed to selectively bind, saturate, and block the immunoglobulin G (IgG) binding site on the endogenous neonatal fragment crystallizable receptor (FcRn) that binds, salvages, and recycles IgG into circulation or transport IgG across the placenta, following nonspecific pinocytosis into endothelial cells and cells of the reticuloendothelial system.
At homeostasis, FcRn recycles IgG to maintain serum IgG levels and extend IgG half-life and also regulates immune cell inflammatory responses to IgG complexes.
By targeting the IgG binding site on FcRn, nipocalimab is expected to block the binding and, hence, recycling of IgG, resulting in a decrease in circulating IgG antibody levels, including pathogenic IgG autoantibodies and alloantibodies.
Therefore, nipocalimab has potential in the treatment of active IIM by decreasing pathogenic IgG antibody concentrations.
The total duration of the study is up to 112 weeks, consisting of 4 study periods: a less than or equal to (<=) 6-week screening period, a 52-week double-blind period, a 48-week long term extension (LTE), and a safety follow-up 8 weeks post last administration of study intervention.
Safety assessments include adverse events (AEs), serious adverse events (SAEs), adverse events of special interest (AESIs), laboratory parameters (hematology and chemistry, including lipid panel), vital signs, and physical examination.

International Myositis Assessment and Clinical Studies Total Improvement Score (IMACS TIS) is a standardized clinical response criteria to assess minimal, moderate and major clinical improvement in adult participants with idiopathic inflammatory myopathies (IIM).
Minimal improvement is defined as IMACS TIS greater than or equal to (>=) 20 in participants with IIM.
The criteria use the 6 IMACS core set measures: physicians' global activity, patient global activity (PtGA), manual muscle testing (MMT)-8, muscle enzymes, myositis disease activity assessment tool (MDAAT), and health assessment questionnaire-disability index (HAQ-DI).
The absolute percentage change in each measure with varying weights is combined to obtain a TIS on a scale of 0 to 100.
Higher score indicates greater improvement.

The CDASI scale is a validated dermatomyositis (DM) specific instrument that systematically quantifies activity and damage in the skin of participant with DM.
Disease involvement in 15 different anatomical locations is rated using three activity scales (erythema, scale, erosion/ulceration) and two damage measures (poikiloderma, calcinosis) measures.
Gottron's papules/sign on the hands are also evaluated in terms of activity (erythema/ulceration) and damage (dyspigmentation or scarring).
Disease activity scores range from 0 to 100.
Higher scores indicate greater disease activity.

Disease activity scores range from 0 to 100.
Higher scores indicate greater disease activity.

Percentage of Participants With Treatment-Emergent Adverse Events (AEs)
Time Frame: Up to 106 weeks
|
Any AE occurring at or after the initial administration of study intervention through the safety follow-up visit will be considered as treatment-emergent.
An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non-investigational) product that does not necessarily have a causal relationship with the intervention.

Up to 106 weeks
|
Percentage of Participants With Treatment-Emergent Serious Adverse Events (SAEs)
Time Frame: Up to 106 weeks
|
Any AE occurring at or after the initial administration of study intervention through the safety follow-up visit will be considered as treatment-emergent.
An SAE is any untoward medical occurrence that at any dose: results in death; is life threatening; requires inpatient hospitalization or prolongation of existing hospitalization; results in persistent or significant disability/incapacity; is a congenital anomaly/birth defect; is a suspected transmission of any infectious agent via a medicinal product; is medically important.

Change From Baseline in Patient-Reported Outcomes Measurement Information System (PROMIS)- Physical Function (PF)-20
Time Frame: Baseline and Week 52
|
PROMIS-PF-20 is a participant self-administered 20-item questionnaire assessing the physical function domain.
It includes 14 items regarding patients' ability to conduct specific functional activities and 6 items regarding the extent to which their health limits their ability to perform a range of physical activities currently.
The 5-point response options for the former items range from 1 "Unable to do" to 5 "Without any difficulty" and the latter items range from 1 "Cannot do" to 5 "Not at all" with higher scores indicating better functioning.
The overall score ranges from 0 to 100, where higher score indicates better physical function.

Change From Baseline in Functional Disability Using the Health Assessment Questionnaire-disability Index (HAQ-DI)
Time Frame: Baseline, Weeks 24 and 52
|
HAQ-DI score assess functional status of participant.
It is 20 question instrument that assess degree of functional disability a person has in accomplishing tasks in 8 functional areas (dressing, arising, eating, walking, hygiene, reaching, gripping, and common activities of daily living).
Responses in each functional area are scored from 0=indicating no difficulty, to 3=indicating inability to perform a task in that area.
Total HAQ score is average of the computed categories scores ranging from 0-3 where 0=least difficulty and 3=extreme difficulty.
Lower scores are indicative of better functioning.
