Description

Summary

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, 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.

Official Title

An Open-Label Uncontrolled Multicenter Study to Evaluate the Pharmacokinetics, Pharmacodynamics, Safety and Activity of Nipocalimab in Children Aged 2 to Less Than 18 Years With Generalized Myasthenia Gravis

Open to people ages 2-17

  • Diagnosis of myasthenia gravis (MG) with generalized muscle weakness meeting the clinical criteria for generalized myasthenia gravis (gMG) as defined by the Myasthenia Gravis Foundation of America (MGFA) Clinical Classification Class IIa/b, IIIa/b, or IVa/b at screening
  • Has a documented positive serologic test for acetylcholine receptor (anti-AChR) antibodies or muscle-specific tyrosine kinase (anti-MuSK) antibodies that will be confirmed at screening
  • A participant using herbal, naturopathic, traditional Chinese remedies, ayurvedic or nutritional supplements, or medical marijuana (with a doctor's prescription) is eligible if the use of these medications is acceptable to the Investigator. These remedies must remain at a stable dose and regimen throughout the study
  • Has sufficient venous access to allow drug administration by infusion and blood sampling as per the protocol
  • Participants should have a body weight and body mass index between 5th and 95th percentile for age and sex. Obese participants greater than 95th percentile and underweight participants below 5th percentile may participate following medical clearance
  • A female of childbearing potential must have a negative highly sensitive serum (beta-human chorionic gonadotropin [beta-hCG]) at Screening and a negative urine pregnancy test at Day 1 prior to administration of study intervention

You CAN'T join if...

  • Has a history of severe and/or uncontrolled liver, gastrointestinal, renal, pulmonary, cardiovascular, psychiatric, neurological or musculoskeletal disorder or any other medical disorder including laboratory abnormalities, that, in the opinion of the Investigator, might interfere with participant's full participation in the study, or might jeopardize the safety of the participant or the validity of the study results
  • Has any confirmed or suspected clinical immunodeficiency syndrome not related to treatment of his/her generalized myasthenia gravis (gMG), or has a family history of congenital or hereditary immunodeficiency unless confirmed absent in the participant
  • Has had a thymectomy within 12 months prior to screening, or thymectomy is planned during the Active treatment Phase of the study
  • Has shown a previous severe immediate hypersensitivity reaction, such as anaphylaxis to therapeutic proteins (example, monoclonal antibodies)
  • Has experienced myocardial infarction, unstable ischemic heart disease, or stroke within 12 weeks of screening
