Arm Intervention/treatment
Experimental: IgPro20 Biological: Immune globulin subcutaneous (Human)
IgPro20 is a 20% (weight per volume [w/v]) liquid formulation of human immunoglobulin for subcutaneous (SC) use. Subjects will receive weekly infusions of IgPro20 for a total of 24 weeks at a dose based on the subject's IgPro20 dose in the pivotal study ZLB06_002CR (NCT01199705).

Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Median of the Individual Subject's Rate of Adverse Events (AEs) Per Infusion [ Time Frame: 24 weeks ]
    The rate was calculated by counting all newly developed or worsened AEs within a subject and dividing by the total number of IgPro20 infusions administered to this subject. Subsequently, the median of these individual AE rates per infusion was calculated. AE rates were classified (i) by severity (mild, moderate, severe) and (ii) by causal relationship to study medication (not related or unlikely related; at least possibly related [i.e., possibly related, probably related, or related]).


Secondary Outcome Measures :
  1. Overall Rate of AEs Per Infusion [ Time Frame: 24 weeks ]
    The rate was calculated by counting all newly developed or worsened AEs during the treatment period in all subjects and dividing the total number of AEs by the total number of IgPro20 infusions administered. In addition, individual AEs were classified (i) by severity (mild, moderate, severe) and (ii) by causal relationship to study medication (not related or unlikely related; at least possibly related [i.e., possibly related, probably related, or related]). The AE rates per infusion by severity and causal relationship to study medication were calculated by dividing the number of AEs in each category by the total number of IgPro20 infusions.

  2. Number of Subjects With Newly Developing or Worsening AEs [ Time Frame: 24 weeks ]
    Number of subjects with AEs, overall and classified (i) by severity (mild, moderate, severe) and (ii) by causal relationship to study medication (not related or unlikely related; at least possibly related [i.e., possibly related, probably related, or related]).

  3. Percentage of Infusions With Subject-assessed Tolerability of at Least 'Good' [ Time Frame: 24 to 72 hours after infusion ]
    Subjects assessed their overall perception of local tolerability at the infusion site throughout the study in the subject diary within a time window of 24 h to 72 h after the end of the latest infusion by assessing it as "very good", "good", "fair", or "poor". The reported percentage represents the percentage of subjects with local tolerability assessments of "very good" or "good" at any given study infusion.

  4. IgG Trough Level [ Time Frame: 24 weeks ]
    Serum IgG trough levels at the completion visit compared to the baseline visit of the follow-up study. IgG trough levels at baseline, at the completion visit, and the change from baseline to the completion visit are shown

  5. Annualized Rate of Clinically Documented Serious Bacterial Infections (SBIs) [ Time Frame: 24 weeks ]
    SBIs are defined as bacterial pneumonia, bacteremia and septicemia, osteomyelitis/septic arthritis, bacterial meningitis, or visceral abscess. The annualized rate was based on the total number of SBIs and the total number of subject study days for all subjects in the FAS and PPS and adjusted to 365 days.

  6. Number of Infection Episodes (Serious and Non-serious) [ Time Frame: 24 weeks ]
  7. Number of Days Out of Work/School/Kindergarten/Day Care or Unable to Perform Normal Daily Activities Due to Infections. [ Time Frame: 24 weeks ]
    Median number of days out of work/school/kindergarten/day care or unable to perform normal daily activities due to infections.

  8. Number of Days of Hospitalization Due to Infections. [ Time Frame: 24 weeks ]
    Median number of days of hospitalization due to infections.

  9. Duration of Use of Antibiotics for Infection Prophylaxis and Treatment [ Time Frame: 24 weeks ]
    Median number of days of use of antibiotics for infection prophylaxis and/or treatment


Other Outcome Measures:
  1. Rate of Infection Episodes (Serious and Non-serious) [ Time Frame: 24 weeks ]
    The annualized rate of infection episodes (serious and non-serious) was based on the total number of infection episodes and the total number of subject study days for all subjects in the FAS population and the PPS population and adjusted to 365 days.
