Badanie nipokalimabu u dzieci w wieku od 2 do mniej niż 18 lat z uogólnioną miastenią

2 listopada 2026 zaktualizowane przez: Janssen Research & Development, LLC

Otwarte, niekontrolowane, wieloośrodkowe badanie oceniające farmakokinetykę, farmakodynamikę, bezpieczeństwo i aktywność nipokalimabu u dzieci w wieku od 2 do mniej niż 18 lat z uogólnioną miastenią

The purpose of this study is to determine the effect of nipocalimab on total serum immunoglobulin G (IgG) in pediatric participants 2 to less than (<) 18 years of age (globally) and 8 to <18 years of age (for Unites Stated (US) sites only), the safety and tolerability of treatment with nipocalimab in children and adolescents and to evaluate the pharmacokinetics (PK) of nipocalimab in children and adolescents with generalized myasthenia gravis (gMG) who have an insufficient clinical response to ongoing, stable standard-of-care therapy.

Change from Baseline in Myasthenia Gravis -Activities of Daily Living (MG-ADL) Score
Ramy czasowe: Up to 3 years

Change from baseline in MG-ADL score will be reported. The MG-ADL score provides a rapid assessment of the participant's myasthenia gravis (MG) symptom severity. Eight functions (talking, chewing, swallowing, breathing, impairment of ability to brush teeth or comb hair, impairment of ability to arise from a chair, double vision, eyelid droop) are rated on a 4-point scale: 0 (no impairment) to 3 (severe impairment). The total score will be sum of eight function scores and can range from 0 to 24. A higher score indicates greater symptom severity.

The QMG score is a standardized quantitative strength assessment comprising 13 components (and is administered by a trained qualified healthcare professional [HCP] eg, physician, physician assistant, nurse practitioner, nurse). The quantitative results of each strength component are mapped to the following 4-point scale: 0 equals to (=) none, 1 = mild, 2 = moderate and 3 = severe. The total score will be sum of 13 components scores and can range from 0 to 39. A higher score indicates greater weakness.
