Participant Flow

The target population consisted of male or female children aged between 4 and 8 years who had clinician-diagnosed asthma of at least 3 months. Subjects were expected to be stable on treatment with albuterol as needed and/or inhaled corticosteroids and/or leukotriene receptor antagonists for 2 weeks prior to screening. The first subject enrolled on 06 May 2021 and the last subject completed the study on 08 July 2021. Subjects were enrolled at 2 US study centers.

The randomized treatment phase started after a screening period with a maximum duration of 14 days. Subjects who were taking budesonide in any form at Visit 1 were switched to another corticosteroid with a washout of budesonide of 3 to 7 days. In addition to the 12 subjects randomized, 1 subject was screened but did not participate (1 screen failure).

PRIMARY outcome

Timeframe: A total of 10 samples were taken per treatment visit at pre-dose and at 10, 20, 40, 60, 120, 240, 360, 480 and 720 minutes after dosing.

Population: Budesonide PK samples were available from 12 children. There were 2 instances, one for each treatment intervention, where the pre-dose budesonide concentration was considered too high (16% and 46% of Cmax), potentially having an impact on the post-dose concentrations. There was also 1 instance in the Pulmicort Respules 1mg treatment intervention where post-dose samples were not collected due to difficulty with the catheter. PK parameters were not calculated in these three instances.
