OBJECTIVES: Double-blind study comparing efficacy and safety of the topically acting corticosteroid beclomethasone dipropionate (BDP) to prednisone (PD) in patients with active, mild-to-moderate ulcerative colitis (UC).

METHODS: Overall, 282 patients were randomized to receive BDP-prolonged release tablets 5 mg once daily for 4 weeks and then every other day for an additional 4 weeks or oral PD 40 mg once daily for the initial 2 weeks tapered of 10 mg every 2 weeks during the 8-week study period. Efficacy end point was the non-inferiority of BDP vs. PD in terms of Disease Activity Index (DAI) score <3 or reduction by at least 3 points for patients with a baseline DAI ≥7 at week 4. Safety end point was the proportion of patients with steroid-related adverse events (AEs) and cortisol <150 nmol/l at week 4.

RESULTS: DAI response rates at week 4 were 64.6% and 66.2% with BDP and PD, respectively, demonstrating non-inferiority of BDP vs. PD (delta: −1.56; 95% confidence interval (CI) −13.00–9.88,P=0.78). Patients with steroid-related AEs and cortisol <150 nmol/l at week 4 were 38.7% in the BDP group and 46.9% in the PD group (P=0.17 between groups). No safety signals were observed in both the groups.

CONCLUSIONS: BDP was non-inferior to PD in the treatment of active UC, with a good safety profile in both the groups.
