About

This was a multicenter, open label, randomized, controlled, safety trial in subjects aged 6-75 years with a diagnosis of moderate to severe, persistent asthma.

Upon successful completion of the screening period (~2 weeks), each subject entered the 24 week study.

Sex: All

Ages: 6 to 75 years old

Volunteers: No Healthy Volunteers
