An Open-label, Multicenter Study to Assess the Pharmacokinetics (PK), Safety, and Tolerability of Subcutaneous IgPro20 in Immunoglobulin (IG) Treatment-naïve Participants With Primary Immunodeficiency (PID)
Completed · Phase 4
Conditions studied: Primary Immunodeficiency
In brief
This is an open-label, multicenter, phase 4 study in IG treatment-naïve participants with PID, conducted in the United States (US), to assess the PK, safety, and tolerability of IgPro20. The primary objective of this study is to characterize the PK of IgPro20 and to assess the safety and tolerability of IgPro20 in IG treatment-naïve participants with PID who are aged greater than or equal to (\>=) 18 years.

You may qualify if…
- Participants must be aged >=18 years.
- Participants must have a confirmed and documented diagnosis of PID, must be IG treatment-naïve and have an IgG level less than or equal to (<=) 400 milligrams per deciliter(mg/dL) at Screening.

- Participants with hyperprolinemia.
- Participants who are receiving the following medications:
- Systemic corticosteroids (prednisone or equivalent; average daily dose of greater than [>] 15 mg) from 4 weeks before Screening.
- Any dose of systemic immunosuppressants within 9 months or 5 times the half-life (t½) plus 6 months before Screening, whichever is longer.
- Any dose of biologic therapies with influence on the immune system (eg, tumor necrosis factor inhibitors, interleukin inhibitors, B-cell inhibitors), including investigational agents, within 12 months or 5 times the t½ plus 6 months before Screening, whichever is longer.
- Participants who are currently receiving anti-coagulation therapy.
