Study of Immune Globulin Intravenous (Human) GC5107 in Subjects With Primary Humoral Immunodeficiency

Phase 3
Completed
Conditions
Immunologic Deficiency Syndromes
Interventions
Biological: GC5107
Registration Number
NCT02783482
Lead Sponsor
Green Cross Corporation
Brief Summary

The purpose of this study is to evaluate the safety, efficacy and Pharmacokinetics of Immune Globulin Intravenous (Human) GC5107 in subjects with Primary Humoral Immunodeficiency (PHID).

Detailed Description

This was a prospective, open-label, single-arm, historically controlled, multicenter phase 3 study measuring the safety, efficacy and pharmacokinetics and tolerability of GC5107 in subjects with Primary Humoral Immunodeficiency disease (PHID).

Subjects received intravenous infusions of the investigational product at the same dose and interval as used for their previous Immunoglobulin intravenous (IVIG) maintenance therapy. GC5107 was administered every 21 or 28 days for a period of 12 months.

Primary Outcome Measures
NameTimeMethod
The Proportion of Infusions With Temporally Associated Adverse Events (TAAEs) That Occur Within 72 Hours Following an Infusion of Test ProductWithin 72 hours after an infusion of GC5107

The proportion of infusions with temporally associated adverse events occurring during or within 72 hours following infusion, whether or not they were thought to be related to GC5107

The Incidence of Acute Serious Bacterial Infections (SBI)One year

The incidence of acute serious bacterial infections (aSBIs) meeting FDA guidance criteria, which includes bacterial pneumonia, bacteremia/sepsis, bacterial meningitis, visceral abscesses, and osteomyelitis/septic arthritis.

Efficacy data is evaluated by comparing the frequency of acute serious bacterial infections per subject per year according to the FDA guideline of an upper one-sided 99% confidence limit \< 1.0 per subject per year.

Secondary Outcome Measures
NameTimeMethod
The Incidence of Infections Other Than Acute Serious Bacterial InfectionsOne year
The Number of Days of Oral Therapeutic AntibioticsOne year

Based on the total number of days of oral (PO) therapeutic antibiotics for each subject. Mean and SD are calculated based on weighting for the duration of data available for each subject, where duration is defined as (date of last visit - first infusion date + 1) for subjects who complete the study; and defined as (date of withdrawal - first infusion date + 1) for subjects who withdraw from the study.

The Number of Days of Unscheduled Physician Visits Due to InfectionsOne year

Based on the total number of days of unscheduled physician visits due to infections for each subject. Mean and SD are calculated based on weighting for the duration of data available for each subject, where duration is defined as (date of last visit - first infusion date + 1) for subjects who complete the study; and defined as (date of withdrawal - first infusion date + 1) for subjects who withdraw from the study.

The Number of Days of Hospitalizations Due to InfectionsOne year

Subject with no experience of specific event will be included in the analysis as zero incidence, zero day, or zero time duration. The mean and SD will be calculated weighting for the duration of data available for each subject.

The Number of Days of Intravenous (IV) Therapeutic AntibioticsOne year

Based on the total number of days of IV therapeutic antibiotics for each subject. Mean and SD are calculated based on weighting for the duration of data available for each subject, where duration is defined as (date of last visit -first infusion date + 1) for subjects who complete the study; and defined as (date of withdrawal - first infusion date + 1) for subjects who withdraw from the study.

The Number of Days Missed From Work/School/Kindergarten/Daycare, or Days Unable to Perform Normal Daily Activities Due to InfectionsOne year

Based on the total number of days missed from work/school/kindergarten/daycare or days unable to perform normal daily activities due to infections for each subject. Mean and SD are calculated based on weighting for the duration of data available for each subject, where duration is defined as (date of last visit - first infusion date + 1) for subjects who complete the study; and defined as (date of withdrawal - first infusion date + 1) for subjects who withdraw from the study.
