  • Females and males aged from ≥1 year to \<18 years old
  • Confirmed diagnosis of Chronic Immune Thrombocytopenia (ITP) according to American Society of Hematology (ASH) 2019 guidelines
  • Platelets count \<30x10\^9/L at the Baseline Visit

  • Sexually active females who have been using at least 1 acceptable form of birth control for a minimum of 30 days (or a minimum of 3 months for hormonal contraceptives) prior to the Screening visit and must agree to use at least 1 acceptable method of contraception throughout the study and for 30 days after the last dose of PANZYGA. Acceptable methods of birth control for this study include: intrauterine device (IUD), hormonal contraception, male or female condom, spermicide gel, diaphragm, sponge, or cervical cap. For non-sexually active females who have begun menstruating, abstinence is considered an acceptable method of birth control.
  • Parent or legal guardian must agree and be willing to assist the participant attend study visits, and to follow all protocol requirements and instructions of the study doctor

Exclusion

  • Thrombocytopenia secondary to other diseases (such as Acquired Immunodeficiency Syndrome \[AIDS\] or systemic lupus erythematosus \[SLE\]), drug-related thrombocytopenia, or congenital thrombocytopenia
  • Administration of intravenous immunoglobulin (IGIV) or anti-D immunoglobulin within 3 weeks (+/- 3 days) before enrollment
  • Administration of thrombopoietin receptor agonists when the dose has NOT been stable within 3 weeks before enrollment and a dosage change is planned before Day 32
  • Administration of oral immunosuppressants when the dose has NOT been stable during the preceding 2 months (2 weeks for long-term corticosteroid therapy) and a dosage change is planned before Day 32 (Note: topical agents and inhaled corticosteroid therapy use is permitted)
  • Administration of long-term anti-prolific agents or attenuated androgen therapy when the dose has NOT been stable during the preceding 2 months and a dosage change is planned before Day 32
  • Nonresponsive to previous treatment with IGIV or anti-D immunoglobulin
  • Evidence of an active major bleeding episode at Screening
  • Splenectomy in the previous 3 months or planned splenectomy throughout the study period
  • Evans syndrome (experiencing active disease with 2 out of 3 of the following: autoimmune thrombocytopenia, autoimmune hemolytic anemia, and/or autoimmune neutropenia)
  • Known or suspected human immunodeficiency virus (HIV), hepatitis B virus (HBV), and/or hepatitis C virus (HCV) infections
  • Emergency surgery in the previous 4 weeks
  • Severe liver and/or kidney disease (alanine aminotransferase \[ALT\] \>3x upper limit of normal (ULN), aspartate aminotransferase \[AST\] \>3x upper limit of normal (ULN), and/or creatinine \>120 µmol/L)
  • History of severe hypersensitivity to blood or plasma derived products, or any component of the PANZYGA
  • Known immunoglobulin A (IgA) deficiency and antibodies against IgA
  • History of, or suspected alcohol or drug abuse in the previous year
  • Females who are pregnant or nursing
  • Unable or unwilling to comply with the study protocol
  • Receipt of any other investigational medicinal product within 3 months before study entry
  • Risk factors\* for thromboembolic events in whom the risks outweigh the potential benefit of PANZYGA treatment.
  • Any other condition(s), that in the Investigator's opinion, make it undesirable for the patient to participate in the study or may interfere with protocol compliance.
  • Risk factors include, but are not limited to: obesity, advanced age, hypertension, diabetes, a history of atherosclerosis/vascular disease or thrombotic events, hyperlipidemia, multiple cardiovascular risk factors, acquired or inherited thrombophilic disorders, prolonged periods of immobilization, severe hypovolemia, central venous catheterization, active malignancy and/or known or suspected hyperviscosity.
