MOUNTAIN VIEW, Calif., Aug. 14, 2014 /PRNewswire/ -- Alexza Pharmaceuticals, Inc. (Nasdaq: ALXA) today provided an update on its European Medicines Agency (EMA) post-approval studies for ADASUVE® inhalation powder, pre-dispensed (loxapine).  As part of the ADASUVE approval process with the EMA, Alexza is required to conduct five post-approval studies:

  • a benzodiazepine interaction study - study completed and data submitted to the EMA
  • a controlled study to determine ADASUVE's effect on cardiac rhythms, or a thorough QTc study, with two doses of ADASUVE - study completed and data submitted to the EMA
  • a clinical program designed to evaluate the safety / efficacy of ADASUVE in agitated adolescent patients - the initial study in this program, a Phase 1 dose-ranging study, has been initiated in collaboration with Teva and the first patient dosed
  • a Post-Authorization Safety Study (PASS) - study has been initiated and the first patient dosed
  • a Drug Utilization Study (DUS) - study planned to be initiated in Q4 2014 

"We are encouraged by the progress we are making on the EU post-approval commitments for ADASUVE.  We have already completed two of the studies and submitted the data to the EMA," said James V. Cassella, PhD, Executive Vice President, Research and Development and Chief Scientific Officer of Alexza.  "We are pleased that the first patient in our PASS study and the first patient in our Phase 1 dose-ranging study have been dosed, and look forward to additional patient enrollment in the three ADASUVE studies in the coming months."   

ADASUVE PASS Design
The EMA requested a PASS to better understand the safety profile of ADASUVE in real-world use in Europe, and to assess effectiveness of the risk minimization activities.  This study is a multicenter, multinational, prospective observational study to evaluate the safety of ADASUVE when used in the routine clinical setting in agitated patients.  The study is intended to enroll approximately 1,500 patients from a total of about 20 to 25 centers in five to six EU countries over a 24-month enrollment period.

ADASUVE DUS Design
The EMA requested a DUS to evaluate the patterns of use for ADASUVE in routine clinical practice in Europe.  This multicenter, multinational study entails retrospective review of medical records of patients receiving ADASUVE in real-world settings.  The study is expected to include a total of approximately 1,000 patients from a total of about 20 to 25 centers in five to six EU countries over an 18-month enrollment period.

About ADASUVE (Staccato® loxapine)
ADASUVE is the first and only oral inhalation therapy for the rapid control of mild-to-moderate agitation in adult patients with schizophrenia or bipolar disorder.  The marketing authorization for ADASUVE requires that patients receive regular treatment immediately after administration of the product to control acute agitation symptoms.  It also requires that ADASUVE be administered only in a hospital setting under the supervision of a healthcare professional.  Short-acting beta-agonist bronchodilator treatment should be available for treatment of possible severe respiratory side effects, such as bronchospasm.

ADASUVE combines Alexza's proprietary Staccato system with loxapine, an antipsychotic medicinal product.  The Staccato system is a hand-held inhaler that delivers a drug aerosol to the deep lung that results in intravenous-like pharmacokinetics and rapid systemic effect. For more information about ADASUVE, including the Summary of Product Characteristics and Patient Information Leaflet approved in the EU, please visit the EMA website.  For the full prescribing information including boxed warnings for the U.S., please visit www.adasuve.com

Alexza and Ferrer estimate that as many as eight million adults in the EU alone suffer from schizophrenia or bipolar disorder1.  Agitation is a common symptom for these patients2, characterized by feelings of distress, anxiety and loss of control.
