With the ADASUVE NDA approval, Alexza also has several post-approval requirements, including a large observational clinical trial designed to gather patient safety data based on the real-world use of ADASUVE, as well as a clinical program addressing the safety and efficacy of ADASUVE in agitated adolescent patients.
About Agitation Associated with Schizophrenia and Bipolar I DisorderAgitation is a serious medical problem that can present in a number of psychiatric disorders, including schizophrenia and bipolar I disorder. Of the estimated 3.2 million patients treated for schizophrenia or bipolar I disorder in the U.S. 3, about 90% suffer from agitation in their lifetime 4, due to the natural course of underlying disease or non-compliance with chronic medication. Patients average 11 to 12 episodes of agitation each year 5.
Agitation episodes may escalate unpredictably and, in some cases, necessitate chemical or physical restraint to relieve the individual's distress and to protect care providers and others in close proximity. Rapid, effective and safe intervention is key to returning the agitated person to a less agitated state.

In December 2012, Alexza received a positive opinion from the EMA's Committee for Medicinal Products for Human Use recommending the approval of ADASUVE in the European Union for the rapid control of mild-to-moderate agitation in adult patients with schizophrenia or bipolar disorder. Patients should receive regular treatment immediately after control of acute agitation symptoms.
