  Purpose

The investigators will perform a double blind, placebo controlled clinical trial with Xolair (omalizumab) at four centers to safely and rapidly desensitize patients with severe peanut allergy. The investigators will determine if pretreatment with anti-IgE mAb (Xolair/omalizumab) can greatly reduce allergic reactions and allow for faster and safer desensitization.

Further study details as provided by Children's Hospital Boston:

Primary Outcome Measures:
  • The ability of omalizumab-treated subjects to successfully complete the build-up phase of peanut, and tolerate daily 4,000 mg doses of peanut flour after discontinuing omalizumab. [ Time Frame: 14 wks after the start of oral peanut desensitization (wk 26 of study). ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:
  • The ability of subjects to tolerate an oral dose of 4,000 mg peanut. [ Time Frame: 8 wks after the start of oral peanut desensitization (study wk 20). ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 36
Study Start Date: January 2013
Estimated Study Completion Date: October 2015
Estimated Primary Completion Date: October 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: omalizumab group
Patients will receive omalizumab.
Drug: Omalizumab
subcutaneous injection
Other Name: Xolair
Placebo Comparator: placebo
Patients will receive placebo.
Drug: placebo
subcutaneous injection

Detailed Description:

36 subjects will receive Xolair, and 8 subjects will receive placebo. The study will occur at 4 sites: Boston Children's Hospital, Children's Hospital of Philadelphia, Stanford University and Lurie Children's Hospital.

Patients will be pre-treated with Xolair or placebo before rapid oral peanut desensitization. Patients will continue to receive Xolair during the 8 subsequent weeks of desensitization, receiving their final dose of Xolair one week after reaching the highest tolerated dose of peanut.

  Eligibility

Ages Eligible for Study:   7 Years to 25 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Moderate to severe peanut allergy-sensitive subjects between the ages of 7 to 25 years old.
  • Sensitivity to peanut allergen will be documented by a positive skin prick test result (6 mm diameter wheal or greater)
  • ImmunoCAP IgE level to peanut > 10 kU/L.
  • Sensitivity to peanut allergen based on a double-blind placebo-controlled oral food challenge (DBPCFC) at maximum of cumulative 175 mg of peanut protein dose.

Exclusion Criteria:

  • Subjects with a total IgE at screening of < 50 kU/L > 2,000 kU/L.
  • Positive reaction to the placebo on DBPCFC.
  • Previous reaction to omalizumab.
  • Subjects having a history of severe anaphylaxis to peanut requiring intubation or admission to an ICU, frequent allergic or non-allergic urticaria, or history consistent with poorly controlled persistent asthma, or gastrointestinal or gastroesophageal disease.
