  Outcome Measures
  Show All Outcome Measures

1.  Primary:   The Amount of Peanut Protein Ingested Before An Allergic Reaction is Observed During the Double-blind, Placebo Controlled Food Challenge (DBPCFC) After Completing Treatment With Peanut OIT.   [ Time Frame: 36-60 months ]

2.  Secondary:   The Amount of Peanut Protein Ingested Before An Allergic Reaction is Observed During the Double-blind, Placebo Controlled Food Challenge (DBPCFC) After Completing 12 Months of Blinded Peanut OIT or Placebo Treatment.   [ Time Frame: 12 months ]

3.  Secondary:   The Change From Baseline Through the End of Peanut OIT Treatment in Wheal Size Diameter Following Peanut Skin Prick Testing   [ Time Frame: Baseline to end of open label phase treatment (36-60 months) ]

4.  Secondary:   The Change From Baseline Through the End of Peanut OIT Treatment in Peanut-specific IgE in the Blood   [ Time Frame: Baseline to end of open label phase treatment (36-60 months) ]

5.  Secondary:   The Change From Baseline Through the End of Peanut OIT Treatment in Peanut-specific IgG4 in the Blood.   [ Time Frame: Baseline to end of open label phase treatment (36-60 months) ]
