  7. Subjects with a history of HIV positivity.
  8. Subjects with a history of allergy or intolerance to dibenzoxazepines (amoxapine and loxapine).
  9. Subjects with a known history of contraindications to anticholinergics (bowel obstructions, urinary retention, acute glaucoma).

  13. Subjects who have a clinically significant ECG abnormality.
  14. Subjects with a history of unstable angina, syncope, coronary artery disease, myocardial infarction, congestive heart failure (CHF), stroke, transient ischemic attack (TIA), or a neurological disorder.
  15. Subjects who have a history of pulmonary disease that precludes administration of Staccato Loxapine (asthma, bronchitis, bronchospasm, emphysema).
  16. Subjects who have an FEV1 less than 80% of predicted values on spirometry assessments at Visit 1.
  17. Female subjects who are breastfeeding or have a positive pregnancy test at Visit 1 or Visit 2.
  18. Female participants of child-bearing potential or within 1 year of menopause, and sexually active are excluded unless they use a medically acceptable and effective birth control method throughout the study and for 1 week following the end of the study. Medically acceptable methods of contraception include abstinence, diaphragm with spermicide, intrauterine device (IUD), condom with foam or spermicide, vaginal spermicidal suppository, surgical sterilization, and birth control pills. Unacceptable methods include: the rhythm method, withdrawal, condoms alone, or diaphragm alone.
  19. Subjects who have any other disease or condition, by history, physical examination, or laboratory abnormalities that in the investigator's opinion, would present undue risk to the subject, or may confound the interpretation of study results.

Outcomes

Primary Outcome Measures

Tmax
Tmax = time from inhalation to to maximum observed loxapine concentration
Half-life
Half-life of the terminal elimination phase of loxapine concentrations
ke
elimination rate constant
Clearance
clearance (CL/F) of lozxapine
Cmax
maximum concentration of loxapine observed
Dose Proportionality (AUCinf) by Power Analysis
Dose proportionality by power analysis examines the linear regression of the log-AUC versus log-Dose on a by-patient basis across all doses administered. The slope and 90% confidence interval (CI) provide a clear, quantitative (best practices) assessment of the relationship of drug delivered to dose administered. The units on such analyses are generally those of slope (rise over run), with 1.000 being "perfect". Although any positive slope might be considered clinically useful, a 90% CI within the criteria of 0.800-1.250 may be considered a delivery system which is "as good as it gets".

5. Study Description

Brief Summary
The objective of this study was to assess the safety, tolerability and pharmacokinetics of a single inhaled dose of (administered in 1 or 2 puffs) Staccato Loxapine in healthy volunteers.
Detailed Description
Safety and pharmacokinetic data obtained from 50 subjects (between the ages of 18 to 55 years) entered into this randomized, placebo-controlled study. To obtain 50 enrolled subjects, screening procedures and inclusion/exclusion criteria were evaluated for 126 subjects during a variable screening period of up to 21 days. Once enrolled, subjects were randomized to either Staccato Loxapine or Staccato placebo. Plasma samples for pharmacokinetic analysis were collected beginning on Day 0, pre-dose and continuing for 24 hr post dose. Blood samples for the PK analysis of loxapine and its metabolites (8-OH loxapine, 7-OH loxapine and amoxapine) were obtained at time 0 (immediately before dosing), at 30 sec, 1, 2, 3, 5, 10, 30, 45 min, 1, 2, 4, 6, 12, 24 hr after dosing. Plasma concentrations of loxapine and metabolites were used to estimate the following PK parameters for loxapine and its metabolites: area under the plasma concentration time curve from time 0 extrapolated to infinity (AUCinf), AUC from time 0 to time tlast, the last quantifiable concentration (AUClast), maximum observed plasma concentration (Cmax), observed time of Cmax (tmax), terminal phase elimination rate constant (ke), apparent terminal elimination half life calculated from ke (T½ ), apparent total body clearance / fraction absorbed calculated from AUCinf and dose (CL/F) (for loxapine and the metabolites where permitted by measurable concentrations). Safety was evaluated by the incidence of adverse events, clinical laboratory testing (blood chemistry, hematology, and urinalysis), physical examination, vital signs, pulse oximetry, postural vital signs, 12-lead electrocardiogram, pulmonary function tests, continuous 12-lead Holter monitoring, sedation assessments, akathisia assessments.
