Study Type:	Interventional
Study Design:	Treatment, Randomized, Double Blind (Subject, Caregiver, Investigator, Outcomes Assessor), Placebo Control, Parallel Assignment, Pharmacokinetics Study
Official Title:	Safety, Tolerability, and Pharmacokinetics of Multiple Doses of Staccato® Loxapine for Inhalation in Subjects on Chronic, Stable Antipsychotic Regimens

Further study details as provided by Alexza Pharmaceuticals, Inc.:

Primary Outcome Measures:

Tolerability will be assessed based on treatment emergent adverse events, vital signs, ECG and a visual-analog sedation scale. [ Time Frame: 48 hours ]

Secondary Outcome Measures:

Plasma concentration-time (PK) profiles will be produced for each subject and a mean PK profile for subjects completing for each dose group [ Time Frame: 24 hours ]
PK parameters: tmax, Cmax, AUClast, AUCinf, ke, t1/2 and clearance will be estimated for each subject and for the population using noncompartmental methods. [ Time Frame: 24 hours ]

Enrollment:	40
Study Start Date:	October 2007
Study Completion Date:	December 2007
Primary Completion Date:	December 2007 (Final data collection date for primary outcome measure)

Arms	Assigned Interventions
A: Experimental	Drug: loxapine loxapine aerosol inhalation high dose regimen
B: Experimental	Drug: loxapine loxapine aerosol inhalation middle dose regimen
C: Experimental	Drug: loxapine loxapine aerosol inhalation low dose regimen
D: Placebo Comparator	Drug: placebo placebo aerosol inhalation

Detailed Description:

The purpose of the present Phase 1 study in schizophrenic patients is to assess the safety and pharmacokinetics of multiple doses of Staccato Loxapine given within a 24 hour time period. The study will be conducted in schizophrenic patients who are on chronic, stable antipsychotic medication. Patients meeting entry criteria will be randomized to one of three dose sequences of Staccato Loxapine or to Staccato Placebo. Following administration of medications, safety, tolerability and pharmacokinetic assessments will be conducted at serial time points.
