Secondary
| Measure | Time frame | Description |
|---|---|---|
| Total IgE serum concentrations | pre-dose, 5, 14, 29, 85, and 140 day post-dose | Blood will be collected to measure serum IgE concentrations. |
| Immunogenicity (Anti-FB825 antibody in serum) | pre-dose, 5, 14, 29, 85, and 140 day post-dose | Blood will be collected to measure Immunogenicity. |
| Composite of PK parameters | Pre-dose, 2, 3, 5, 14, 29, 85, and 140 day post-dose | Blood will be collected for the determination of serum FB825 concentrations, Cmax, Tmax, AUC, and terminal half-life.These parameters will be determined using non-compartmental methods. |
