Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a Phase IV, multicenter, open-label study of Asceniv™ administered as an intravenous infusion of Asceniv™ (IGIV) 300-800 mg/kg every 21 or 28 days in approximately 12 pediatric subjects with Primary Immunodeficiency Diseases (PIDD). The study will be conducted at 5-7 centers in the United States, with subjects receiving six (28 day cycle) or seven (21 day cycle) doses of Asceniv™ during the study.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Asceniv

Asceniv™ will be given as an intravenous infusion at the same dose, or higher dose where medically appropriate, as the subject's previous IV Immunoglobulin G treatment (300-800 mg/kg) every 21 or 28 days.

Group Type EXPERIMENTAL

Asceniv™

Intervention Type BIOLOGICAL

Each subject will receive an intravenous infusion of Asceniv™ on Study Day 1 (required to be within 28 days of screening) and every 21 or 28 days thereafter according to their current interval of IGIV treatment. Subjects will receive Asceniv™ at the same dose or higher dose if medically appropriate (300-800 mg/kg), every 21 or 28 days for five months (seven or six doses respectively).

Asceniv™

Each subject will receive an intravenous infusion of Asceniv™ on Study Day 1 (required to be within 28 days of screening) and every 21 or 28 days thereafter according to their current interval of IGIV treatment. Subjects will receive Asceniv™ at the same dose or higher dose if medically appropriate (300-800 mg/kg), every 21 or 28 days for five months (seven or six doses respectively).

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Subject and/or legal guardian must be able to understand the study procedures, have agreed to participate in the study and have voluntarily signed an IEC/IRB approved written informed consent. The consent form or a specific assent form, where required, will be signed and dated by minors.
2. Have confirmed and documented clinical diagnosis of primary immunodeficiency disease including but not limited to: common variable immunodeficiency, X-linked and autosomal forms of agammaglobulinemia, hyper-IgM syndrome, or antibody deficiencies.
3. Be male or female, and ≥ 2 years and \< 12 years at the time of informed consent by subject or legal guardian.
4. Have been receiving IGIV at a dose that has not been changed by \> 25% of the mean dose on a mg/kg basis for at least 3 months prior to study entry.
5. Have two trough levels of IgG in the last year (screening level may be used), and maintained a trough serum IgG level \> 500 mg/dL on the previous 2 assessments prior to receiving Asceniv™. (The trough level must be at least 300 mg/dL above pre-treatment serum IgG levels; with exception for cases of X-linked agammaglobulinemia where no pre-treatment value is available. Documentation will need to include dose, treatment interval and trade name of the IGIV products used for the three doses prior to the first Asceniv™ infusion in this study.
6. For female subjects, be of non-childbearing potential or have a negative pregnancy test prior to study start and be deemed not at risk of becoming pregnant by adherence to a reliable contraceptive method for the duration of the study. Females of non-childbearing potential are defined as prepubertal girls.

Exclusion Criteria

1. Have a known hypersensitivity to immunoglobulin or any excipient in Asceniv™.
2. Have a history of any severe anaphylactic or anaphylactoid reaction to blood or any blood-derived product.

4. Have uncompensated, hemodynamically significant, congenital or other heart disease. Including but not limited to acute coronary syndromes and chronic stable angina.
5. Have a medical condition that is known to cause secondary immune deficiency, such as chronic lymphocytic leukemia, lymphoma, multiple myeloma, or HIV infection.
6. Have a significant T-cell or granulocyte deficiency in number or function (chronic or recurrent absolute neutrophil count \<1000 x 109/L).
7. Have significant renal impairment (defined as an estimated Glomerular Filtration Rate ≤ 50 mL/min/1.73m2); or have a history of acute renal failure.
8. Have abnormal liver function, defined as ALT or AST ≥ 2.5 x ULN.

19. Have a history of hemolysis while undergoing treatment with IGIV therapy.
20. Be morbidly obese as indicated by a Body Mass Index (BMI) ≥40.
21. Have an active viral or bacterial infection or symptoms/signs consistent with such an infection, within the two weeks prior to the Screening Visit. Subjects may be receiving antibiotics as long as signs/symptoms of infection have been absent for two weeks prior to the initial infusion of investigational product (IP).
