The Effect of Xolair (Omalizumab) on Allergy Blood Cells

September 30, 2013 updated by: Creighton University

The Effect of Xolair (Omalizumab) on Inhibiting Leukotriene and Cytokine (IL-4 and IL-13) Release From Blood Basophils

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.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
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.
Time Frame: 1 year
1 year

Secondary Outcome Measures

Outcome Measure
Time Frame
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).
Time Frame: 1 year
1 year
