Title: A Phase II, Multicenter, Randomized, Double-Blind, Placebo-Controlled, Parallel-Group Study to Evaluate the Efficacy, Safety, and Tolerability of Intravenous MEMP1972A in the Prevention of Allergen-Induced Airway Obstruction in Patients With Mild Asthma
Brief Summary: This Phase II, double-blind, placebo-controlled, randomized, parallel-group study is designed to evaluate the efficacy, safety and tolerability of MEMP1972A when administered to patients by intravenous (IV) infusion for the treatment of allergen-induced asthma.

* The patient has an ACQ score of at least 1.5.
* The patient has airway reversibility of at least 12% to beta-agonist administration at screening.
* The patient is currently taking fluticasone at a dosage of at least 440 μg daily (or equivalent). Patients' baseline asthma therapy regimens (including but not limited to inhaled corticosteroids, leukotriene antagonists, 5-lipoxygenase inhibitors, cromolyn) must be stable for 30 days before screening, and continue without dosage changes throughout study.
* The patient has a blood eosinophil count of at least 400/μL.

* Female patients of childbearing potential (not surgically sterile or 2 years postmenopausal), must use a medically accepted method of contraception and must agree to continue use of this method for the duration of the study and for 30 days after the end-of-treatment visit. Acceptable methods of contraception include barrier method with spermicide, abstinence, intrauterine device (IUD), or steroidal contraceptive (oral, transdermal, implanted, and injected).
