Ages Eligible for Study:   6 Years to 75 Years   (Child, Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Signed Informed Consent Form
  • Use of an effective method of contraception for females of childbearing potential
  • Body weight ≥ 20 kg and ≤ 150 kg
  • IgE level ≤ 1300 IU/mL (Note: Subjects with an IgE < 30 IU/mL will be dosed at the lowest level on the dosing table [30 IU/mL], thus enabling better understanding of the role of Xolair in peanut allergic subjects who have low total IgE levels.)
