E.2 Objective of the trial |
E.2.1 | Main objective of the trial |

|
E.2.2 | Secondary objectives of the trial |
The secondary objectives of the study are to evaluate: 1. To further assess the efficacy of IgPro10 as compared to placebo 2. To assess safety of IgPro10 as compared to placebo 3. To assess the IgPro10 concentrations at steady state 4. To assess longer term efficacy and safety of IgPro10 at the end of an OL Treatment Period at Week 72. |

Ongoing active serious infection at Screening (including, but not limited to, pneumonia, bacteremia/septicemia, osteomyelitis/septic arthritis, bacterial meningitis, or visceral abscess) 8. Malignancy in the past 2 years, except for non-melanoma skin cancer, cervical carcinoma in situ, or other in situ cancer if it has been excised and treated within in the past year 9.
