Alexza Pharmaceuticals, Inc. Announces Submission of European Marketing Authorization Application for Adasuve(R) (Staccato(R) Loxapine)

Published: Oct 27, 2011

MOUNTAIN VIEW, Calif., Oct. 27, 2011 /PRNewswire/ -- Alexza Pharmaceuticals, Inc. (Nasdaq: ALXA) announced today that it has submitted its ADASUVE Marketing Authorization Application (MAA) to the European Medicines Agency (EMA). ADASUVE uses Alexza's proprietary Staccato system, an oral inhalation technology that provides rapid systemic delivery of a thermally-generated aerosol of loxapine. The ADASUVE MAA seeks approval for the rapid control of agitation in adult patients with schizophrenia or with bipolar disorder. The Staccato system offers patients a rapid onset of therapeutic effect in a non-invasive, reliable and patient-friendly manner.

"During the last six months, we have conducted pre-submission meetings with both our Rapporteur and Co-Rapporteur, and we believe we have a good understanding of their expectations for our ADASUVE MAA submission," said James V. Cassella, PhD, Senior Vice President, Research and Development at Alexza. "Our submission has been developed to address their inputs and feedback, and we are very excited to have the European review process initiated."

Dr. Cassella continued, "In addition to information from the US NDA, our ADASUVE MAA submission contains additional analysis of the primary efficacy data, and a comprehensive comparison of Staccato loxapine and other injectable drugs used to treat agitation."

Alexza projects that there may be up to eight million adults in Europe who will develop schizophrenia or bipolar disorder in their lifetimes. Agitation is a common symptom among patients suffering from schizophrenia and bipolar disorder. Alexza's market research studies with schizophrenia patient caregivers and bipolar disorder patients indicates these patients currently experience an average of 11 to 12 episodes of agitation each year.

"Our MAA submission is another important step in the development of ADASUVE," stated Thomas B. King, President and CEO of Alexza. "We are optimistic that we will receive timely European review, as we begin to work with our partner Grupo Ferrer, in executing our European commercialization strategy. We believe ADASUVE offers an innovative therapeutic option for the treatment of agitation associated with schizophrenia or bipolar disorder."
