Arms Assigned Interventions
Placebo Comparator: Dose escalation Drug: Albuterol sulfate
Single dose dry powder by inhalation

Detailed Description:
This is a single blind (investigator unblinded), open label, single exposure, non-randomized, single center, outpatient, stepwise, rising dose study in male subjects with mild intermittent asthma to assess topical safety and tolerability of Albuterol Sulfate Acu-30™ DPI, compared with Placebo Acu-30™ DPI. Increasing doses of each drug will be administered in a sequential fashion in 4 steps to 3 different subjects at each step (a total of 12 subjects) with mild intermittent asthma in each step.

Ages Eligible for Study:   18 Years to 45 Years
Genders Eligible for Study:   Male
Accepts Healthy Volunteers:   No

Inclusion Criteria

  • Mild intermittent asthma (meeting GINA specifications -
  • Medically normal subjects with no significant abnormal findings
  • No tobacco (nicotine products) use for at least 2 years before the study starts
  • Normal (or abnormal and clinically insignificant) laboratory values at screening (potassium or glucose levels)
  • No significant medical or surgical conditions (COPD, cystic fibrosis, severe allergic rhinitis)

Exclusion Criteria:

  • Past or present history of experiencing any allergic reaction to the medications/formulations administered in this study, or in the opinion of the Principal Investigator, suggests an increased potential for an adverse hypersensitivity
  • Subject with abnormal screening visit vital signs or clinical laboratory evaluation considered clinically significant by the Principal Investigator
