Brief summary
The objective of this study is to evaluate the pharmacokinetics (PK) and safety profiles of A006, an Albuterol dry powder inhaler (DPI), following a single dose of 110 mcg (T1) or 220 mcg (T2), in healthy male and female adult volunteers.
Detailed description
This study is a randomized, double or evaluator-blinded, single dose, four-arm, crossover PK study in eighteen (18) healthy volunteers, both male and female adults, at 18-40 years of age. All candidates will be screened and only those who satisfy all enrollment criteria will be enrolled into this study. Each study subject will participate in a screening visit and four (4) study visits with one (1) randomized study treatment given in each visit. PK samples will be analyzed with an established LC/MS/MS method. An End-of-Study (EOS) safety evaluation will be conducted at the end of Study Visit-4.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Area Under the Curve of Drug Concentration versus Time (AUC[0-t]) | Within 30 minutes prior to dosing (baseline) to 8 hours post-dose | Subject PK blood samples will be taken prior to dosing and at multiple time points, up to 8 hours after dosing during each treatment period. PK samples will be analyzed using a validated test method. Area under the curve of the drug concentration versus time curve (AUC\[0-t\]) for each treatment period will be calculated using the trapezoidal rule. |
| Peak Plasma Concentration (C[max]) | Within 30 minutes prior to dosing (baseline) to 8 hours post-dose | Subject PK blood samples will be taken prior to dosing and at multiple time points, up to 8 hours after dosing during each treatment period. PK samples will be analyzed using a validated test method. Peak plasma concentration (C\[max\]) will be the highest concentration of Albuterol during each treatment period. |
| Time to Reach Peak Plasma Concentration (t[max]) | Within 30 minutes prior to dosing (baseline) to 8 hours post-dose | Subject PK blood samples will be taken prior to dosing and at multiple time points, up to 8 hours after dosing during each treatment period. PK samples will be analyzed using a validated test method. Time to reach peak plasma concentration (t\[max\]) will be the time it takes to reach the highest concentration of Albuterol during each treatment period. |
| Plasma Albuterol Concentrations at All Time Points | Within 30 minutes prior to dosing (baseline) to 8 hours post-dose | Subject PK blood samples will be taken prior to dosing and at multiple time points, up to 8 hours after dosing during each treatment period. PK samples will be analyzed using a validated test method. Plasma Albuterol concentrations at these time points will be reported during each treatment period. |

| Measure | Time frame | Description |
|---|---|---|
| Heart Rate (HR) at Screening | Within 14 days prior to Day 1 (Visit 1) | Subjects will have their vital signs, i.e., blood pressure and heart rate, measured during the Screening Visit to ensure they are generally healthy. |
| Heart Rate (HR) | Within 30 minutes prior to dosing (baseline) to 8 hours post-dose | Subject will have their vital signs, i.e., blood pressure and heart rate, measured prior to dosing and at multiple time points, up to 8 hours after dosing during each treatment period. |
| 12-Lead ECG QT Intervals at Screening | Within 14 days prior to Day 1 (Visit 1) | 12-Lead ECGs will be performed to measure QT and QTc intervals during the Screening Visit to ensure absence of overt cardiac illnesses. |
| 12-Lead ECG QT Intervals | Within 30 minutes prior to dosing (baseline) to 8 hours post-dose | 12-Lead ECGs will be performed to measure QT and QTc intervals prior to dosing and at multiple time points, up to 8 hours after dosing during each treatment period. |
