Study Evaluating the Effect of IMA-026 on Allergen-Induced Late Asthma Response in Mild Asthma

The Effects of IMA-026 on Allergen-Induced Airway Responses and Airway Inflammation in Subjects With Mild Atopic Asthma

The purpose of this study is to evaluate the effect of IMA-026, an antibody to IL-13, on airway hyperresponsiveness and airway inflammation in mild asthmatics. IMA-026 will be given as 2 injections under the skin 1 week apart at 2 mg/kg each dose. The study will include a screening period and a treatment period which includes doses on day 1 and day 8.

Inclusion Criteria:

1. Healthy men and women 18 to 60 yrs with mild allergic asthma
2. only asthma med is short-acting bronchodilator used not more than twice weekly
3. FEV1 greater than 70% predicted and a demonstrated baseline late response to allergen induction

Exclusion Criteria:

1. Upper respiratory infection or asthma exacerbation with 4 weeks of screening
2. Serious infection requiring parenteral antibiotics or hospitalization with 4 weeks of test article administration
3. Positive radiographic findings indicative of respiratory disease other than asthma
