Pre-assignment details
The randomized treatment phase started after a 2 to 4 week screening period during which participants self-administered single-blind Placebo MDI QID and Ventolin as needed to be used in response to asthma symptoms. In addition to the 1,001 subjects randomized, 875 subjects were screened but did not participate, of which 851 (97.3%) were ineligible, 3 were lost to follow up, 1 was excluded due to a protocol deviation, 18 withdrew by subject decision, and 2 withdrew by parent/guardian decision.
