AstraZeneca's Partner, MAP Pharmaceuticals, Announces Phase 3 Study of Unit Dose Budesonide in Children with Asthma Did Not Meet Primary Endpoints

LONDON, February 23, 2009 /PRNewswire-FirstCall/ -- MAP Pharmaceuticals, Inc. announced today that its initial Phase 3 clinical trial of Unit Dose Budesonide (UDB) for the potential treatment of children with asthma did not meet its co-primary endpoints: asthma control as assessed by changes from baseline in nighttime and daytime composite symptom scores, in either of the doses evaluated when compared with placebo.

AstraZeneca will work with MAP Pharmaceuticals to conduct further analyses of these data to determine appropriate next steps for the program.

AstraZeneca and MAP Pharmaceuticals have a collaboration agreement to develop and commercialize UDB.

MAP Pharmaceuticals is dedicated to developing and commercializing new therapies for children and adults suffering from chronic conditions that are not adequately treated by currently available medicines. The company has two product candidates in Phase 3 clinical development. Unit Dose Budesonide is being developed in collaboration with AstraZeneca for the potential treatment of asthma in children, and MAP0004 is being developed for the potential treatment of migraine. In addition, MAP Pharmaceuticals generates new pipeline opportunities by applying its proprietary drug particle and inhalation technologies to enhance the therapeutic benefits of proven drugs, while minimizing risk, by capitalizing on their known safety, efficacy and commercialization history.
