Patients not Previously Receiving Corticosteroid Therapy
In a 6-week clinical trial, 270 steroid-naive patients with symptomatic asthma being treated with as-needed beta-agonist bronchodilators, were randomized to receive either 40 mcg twice daily of beclomethasone dipropionate HFA inhalation aerosol, 80 mcg twice daily of beclomethasone dipropionate HFA inhalation aerosol, or placebo. Both doses of beclomethasone dipropionate HFA inhalation aerosol were effective in improving asthma control with significantly greater improvements in FEV1, AM PEF, and asthma symptoms than with placebo. Shown below is the change from baseline in AM PEF during this trial.

Figure 1 (Beclomethasone Dipropionate Hfa Inhalation Aerosol 2)
In a 6-week clinical trial, 256 patients with symptomatic asthma being treated with as-needed beta-agonist bronchodilators, were randomized to receive either 160 mcg twice-daily of beclomethasone dipropionate HFA inhalation aerosol (delivered as either 40 mcg/actuation or 80 mcg/actuation) or placebo. Treatment with beclomethasone dipropionate HFA inhalation aerosol significantly improved asthma control, as assessed by FEV1, AM PEF, and asthma symptoms, when compared to treatment with placebo. Comparable improvement in AM PEF was seen for patients receiving 160 mcg twice-daily beclomethasone dipropionate HFA inhalation aerosol from the 40 mcg and 80 mcg strength products.
Patients Responsive to a Short Course of Oral Corticosteroids
In another clinical trial, 347 patients with symptomatic asthma, being treated with as-needed inhaled beta-agonist bronchodilators and, in some cases, inhaled corticosteroids, were given a 7 to 12-day course of oral corticosteroids and then randomized to receive either 320 mcg daily of beclomethasone dipropionate HFA inhalation aerosol, 672 mcg of CFC-BDP, or placebo. Patients treated with either beclomethasone dipropionate HFA inhalation aerosol or CFC-BDP had significantly better asthma control, as assessed by AM PEF, FEV1 and asthma symptoms, and fewer study withdrawals due to asthma symptoms, than those treated with placebo over 12 weeks of treatment. A daily dose of 320 mcg beclomethasone dipropionate HFA inhalation aerosol administered in divided doses provided comparable control of AM PEF and FEV1 as 672 mcg of CFC-BDP. Shown below are the mean AM PEF results from this trial.

Patients Previously on Inhaled Corticosteroids
In a 6-week clinical trial, 323 patients who exhibited a deterioration in asthma control during an inhaled corticosteroid washout period were randomized to daily treatment with either 40, 160, or 320 mcg twice-daily beclomethasone dipropionate HFA inhalation aerosol or 42, 168 or 336 mcg twice-daily CFC-BDP. Treatment with increasing doses of both beclomethasone dipropionate HFA inhalation aerosol and CFC-BDP resulted in increased improvement in FEV1, FEF25-75% (forced expiratory flow over 25% to 75% of the vital capacity) and asthma symptoms. Shown below is the change from baseline in FEV1 as percent predicted after 6 weeks of treatment.
