Lower systemic drug exposure observed compared to currently marketed

conventional nebulized budesonide

MOUNTAIN VIEW, Calif., March 24 /PRNewswire-FirstCall/ -- MAP Pharmaceuticals, Inc. (Nasdaq: MAPP) announced today that in a pharmacokinetic clinical trial Unit Dose Budesonide (UDB) demonstrated lower systemic drug exposure when compared to the currently marketed conventional nebulized budesonide. UDB is MAP Pharmaceuticals' proprietary nebulized formulation of budesonide, currently in Phase 3 clinical development, for the potential treatment of pediatric asthma. UDB is designed to be administered more quickly and to provide efficacy at lower doses than conventional nebulized budesonide, which is the current leading treatment for pediatric asthma.

The clinical trial was a randomized, open label, cross-over study evaluating the pharmacokinetic profile of two doses of UDB given twice daily in 32 adults with mild to moderate asthma. A 0.135 mg dose of UDB was compared as an alternative to a 0.25 mg dose of conventional nebulized budesonide given twice daily, and a 0.25 mg dose of UDB was compared as an alternative to a 0.5 mg dose of conventional nebulized budesonide given twice daily.

In this study UDB demonstrated faster times to maximum blood concentrations as compared to conventional nebulized budesonide, and had similar maximum blood concentrations. No serious adverse events were reported in the study and nebulization time for UDB in this adult population was shorter than for the currently marketed conventional nebulized budesonide product.

"We are pleased to confirm that the UDB doses we are evaluating as part of our Phase 3 clinical program resulted in lower systemic drug exposure c
