Primary Outcome Measures:
  • Safety [ Time Frame: 85 Days ] [ Designated as safety issue: Yes ]
    The safety and tolerability of MEDI4212 will be assessed by summarizing adverse events (AEs) and serious adverse events (SAEs). The occurrence of treatment-emergent adverse events (TEAEs) and treatment-emergent serious adverse events (TESAEs) will be summarized immediately following the first administration of investigational product through the end of study (Day 85).

Secondary Outcome Measures:
  • Evaluation of the PK of MEDI4212 [ Time Frame: 85 Days ] [ Designated as safety issue: No ]
    The secondary endpoints of the study include PK and IM,and PD of MEDI4212 on free IgE levels following single SC or IV dosing. The PK parameters to be obtained and reported include: Cmax - the maximum observed serum concentration of MEDI4212 • Tmax - the time to maximum concentration ( or time of the observed Cmax) • AUC0-∞ - the area under the serum concentration-time curve from time zero to infinity • AUC0-t - the area under the serum concentration-time profile from time zero to the last measurable time point • t1/2 - the terminal elimination half-life • CL - systemic clearance

  • Evaluation of the IM of MEDI4212 [ Time Frame: 85 Days ] [ Designated as safety issue: No ]
    Immunogenicity The presence of ADA in serum will be assessed and results will be analyzed by summarizing the number and percentage of subjects who develop detectable ADA by treatment group. Anti-drug antibody titers will also be reported.

  • Effect of MEDI4212 on free IgE [ Time Frame: 85 Days ] [ Designated as safety issue: No ]
    Pharmacodynamics Serum free IgE will be assessed and the results are expected to be listed by treatment group and summarized for means at different time points. Changes from baseline will also be summarized.
