Healthy volunteers: no

Brief summary:
This randomized, double-blind, double-dummy, placebo-controlled, parallel-group, 12-week study will evaluate the efficacy and safety of beclomethasone dipropionate (80 or 160 mcg/day) administered via breath-actuated inhaler (BAI) and metered-dose inhaler (MDI) in pediatric patients 4 through 11 years of age with persistent asthma, compared with placebo.

Patients took 1 inhalation (with assistance from parents/guardians/caregivers, as needed) from each of 2 devices (BAI device followed by MDI device in that order) twice daily as per the double-dummy study design: 1 BAI treatment or placebo device and 1 MDI treatment or placebo device for a total of 2 inhalations each time.

Detailed description:

Arms:
arm 1: Beclomethasone dipropionate (BDP) was administered via a breath-actuated inhaler (BAI) twice daily (40 mcg twice a day).

Placebo MDI twice daily for blinding.

Albuterol/salbutamol hydrofluoroalkane (HFA) metered-dose inhaler (MDI) at 90 mcg ex-actuator) or equivalent was used as rescue medication throughout the study. arm 2: Beclomethasone dipropionate (BDP) was administered via a breath-actuated inhaler (BAI) twice daily (80 mcg twice a day).

Placebo MDI twice daily for blinding.

Albuterol/salbutamol hydrofluoroalkane (HFA) metered-dose inhaler (MDI) at 90 mcg ex-actuator) or equivalent was used as rescue medication throughout the study. arm 3: Beclomethasone dipropionate (BDP) was administered via a metered-dose inhaler (MDI) twice daily (40 mcg twice a day).

Placebo BAI twice daily for blinding.

Albuterol/salbutamol hydrofluoroalkane (HFA) metered-dose inhaler (MDI) at 90 mcg ex-actuator) or equivalent was used as rescue medication throughout the study. arm 4: Beclomethasone dipropionate (BDP) was administered via a metered-dose inhaler (MDI) twice daily (80 mcg twice a day).

Placebo BAI twice daily for blinding.

Albuterol/salbutamol hydrofluoroalkane (HFA) metered-dose inhaler (MDI) at 90 mcg ex-actuator) or equivalent was used as rescue medication throughout the study. arm 5: Placebo was administered via breath-actuated inhaler (BAI) twice daily. Additionally placebo was administered via metered-dose inhaler (MDI) twice daily.

Albuterol/salbutamol hydrofluoroalkane (HFA) metered-dose inhaler (MDI) at 90 mcg ex-actuator) or equivalent was used as rescue medication throughout the study.

Interventions: intervention 1: Beclomethasone dipropionate BAI intervention 2: Placebo BAI intervention 3: albuterol/salbutamol 90 mcg intervention 4: Beclomethasone dipropionate MDI intervention 5: Placebo MDI
Intervention descriptions: intervention 1: Beclomethasone dipropionate (BDP), was delivered by a single inhalation using a breath-actuated inhaler (BAI) at levels of 40 mcg or 80 mcg per inhalation, twice each day. intervention 2: Placebo was delivered by a single inhalation using a breath-actuated inhaler (BAI) twice each day. intervention 3: Rescue medication (albuterol/salbutamol hydrofluoroalkane (HFA) MDI \[90 mcg ex-actuator\] or equivalent) for use on an as-needed basis for the immediate relief of asthma symptoms throughout the treatment period. intervention 4: Beclomethasone dipropionate (BDP), was delivered by a single inhalation using a metered-dose inhaler (MDI) at levels of 40 mcg or 80 mcg per inhalation, twice each day. intervention 5: Placebo was delivered by a single inhalation using a metered-dose inhaler (MDI) twice each day.
