About this trial
This is an interventional basic science trial for Asthma focused on measuring Allergic Asthma, Anti IgE, Xolair, Basophil, IL-13, IL-4, Histamine
Eligibility Criteria
Inclusion Criteria:
- 2 year history of ragweed allergic rhinitis
- positive skin prick tests to ragweed >5 mm wheal diameter
- serum IgE <700 iU/m
Exclusion Criteria:
- Use of prohibited medications (e.g. antihistamine in past 7 days and topical or oral corticosteroids in past 1 month, beta-agonist or theophylline for 1 week
- History of immunotherapy in the past 2 years
- Exposure to Omalizumab in the past 2 years
- Clinically significant non-allergic or perennial rhinitis to avoid mediator release due to environmental allergens
- Asthma other than mild intermittent
- Women of childbearing potential who are not on an accepted form of birth control, as well as women who are breastfeeding
- Known sensitivity to study drug Xolair
- Patients with severe medical condition(s) that in the view of the investigator prohibits participation in the study
- Patients with a previous history of cancer
- Use of any other investigational agent in the last 30 days
Sites / Locations
- Creighton University Medical Center

Xolair at 0.016 mg/kg/IgE(iu/ml)/4 wks
Outcomes
Primary Outcome Measures
To determine if Xolair (omalizumab) inhibits basophil leukotriene secretion & to compare this with its inhibition of histamine release. We will also compare this inhibition in basophils stimulated with allergen vs anti-IgE vs calcium ionophore.
Secondary Outcome Measures
To determine the effect of Xolair (omalizumab) on IL-4 &vIL-13 secretion. To compare the effect of Xolair on IL-4 vs IL-13 secretion from basophils stimulated with allergen, anti-IgE & calcium ionophore (ionomycin).

5. Study Description
Brief Summary
We are studying Xolair (omalizumab) to see it's effect on allergic blood cells. The blood tests will be done in a test tube to see if they react differently before and after treatment. The blood cells will be mixed with to whatever the person is allergic.
Detailed Description
Must be allergic-asthma with IgE between 30 and 700 IU/ml.
