About Alexza Pharmaceuticals, Inc.
 
Alexza is a pharmaceutical company focused on the research, development and commercialization of novel, proprietary products for the acute treatment of central nervous system conditions.  Alexza's technology, the Staccato® system, vaporizes unformulated drug to form a condensation aerosol that, when inhaled, allows for rapid systemic drug delivery through deep lung inhalation.  With the Staccato system, a drug is quickly absorbed through the lungs into the bloodstream, providing speed of therapeutic onset that is comparable to intravenous administration, but with greater ease, patient comfort and convenience. 
 
ADASUVEâ„¢ (Staccato loxapine) is Alexza's lead program, which is being developed for the acute treatment of agitation associated with schizophrenia or bipolar I disorder in adults.  Alexza completed and announced positive results from both of its Phase 3 clinical trials and initially submitted the ADASUVE New Drug Application (NDA) in December 2009.  In October 2010, the Company received a complete response letter (CRL) from the U.S. Food and Drug Administration (FDA) regarding the application.  The Company completed an end-of-review meeting with the FDA in December 2010, a REMS guidance meeting with the FDA in April 2011, and the ADASUVE NDA was resubmitted in August 2011.  In December 2011, the ADASUVE NDA was the subject of an advisory committee meeting.  In January 2012, Alexza received notice of a 90-day extension of the PDUFA goal date, from February 4, 2012 to May 4, 2012.   In May 2012, Alexza received a second CRL from the FDA regarding the ADASUVE NDA and on June 22, 2012, the Company resubmitted the ADASUVE NDA.  The resubmitted ADASUVE NDA has a PDUFA goal date of December 21, 2012.
