NEWS RELEASE - for immediate release

Alexza Announces Submission of Responses to the

EMA Day 120 List of Questions for the ADASUVE™ MAA

Mountain View, California - July 18, 2012 - Alexza Pharmaceuticals, Inc. (Nasdaq: ALXA) announced today that it has submitted its responses regarding the ADASUVE Marketing Authorization Application (MAA) to the European Medicines Agency (EMA). In March 2012, Alexza received the Committee for Medicinal Products for Human Use Consolidated List of Questions (Day 120 List of Questions) regarding Alexza’s ADASUVE MAA. In May 2012, Alexza and its European corporate partner, Grupo Ferrer, met with the Rapporteur, Co-Rapporteur and EMA to further understand specifics of the major objections raised in the Day 120 List of Questions. The submitted responses are intended to address the questions outlined in the Day 120 List of Questions. According to the published EMA timetables, Alexza expects to receive the Day 180 List of Outstanding Issues for the ADASUVE MAA in late September 2012.

Alexza also announced today that it has completed the follow-up from the May 2012 EU Pre-Approval Inspection (PAI). This inspection resulted in no findings the EMA classified as Critical or Major deficiencies. The EU PAI resulted in 12 findings classified as Other and 4 recommendations. The EMA has accepted Alexza’s final corrective action plan, and proposed timing for the action plan completion and reporting. Alexza expects to receive its EU Good Manufacturing Practices (GMP) Certificate for its Mountain View, California facility as a result of this outcome.
