Brief summary
The investigators will look at TPI-1020 safety and tolerability in mild to moderate asthmatic smoker subjects.
Detailed description
This study will assess and compare the safety and tolerability of inhaled TPI 1020 versus budesonide. Pharmacokinetic (PK) and pharmacodynamic (PD) parameters will also be studied in a sub-group of subjects.
Interventions
600 mcg BID x 14 days followed by 1200 mcg BID x 7 days
400 mcg BID x 14 days then 800 mcg/day x 7 more days

Exclusion criteria
* History or symptoms of significant autoimmune, hematological, or neurological disease, including transient ischemic attack (TIA), stroke, seizure disorder, or behavioural disturbances that are judged clinically significant by the Investigator * History of serious adverse reaction or hypersensitivity to corticosteroids * Abnormal chest X-ray that is judged clinically significant * Pregnant or lactating or have positive plasma pregnancy test * Use of oral/parenteral/inhaled corticosteroids within the last 28 days or injectable depot corticosteroids within the last 6 weeks. * Use of any other asthma-related medications within 1 month of Screening
