Oral prolonged release beclomethasone dipropionate and prednisone in the treatment of active ulcerative colitis: results from a double-blind, randomized, parallel group study.

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.

Tralokinumab for moderate-to-severe UC: a randomised, double-blind, placebo-controlled, phase IIa study.

OBJECTIVE: Interleukin-13 (IL-13) has been implicated as a key driver of UC. This trial evaluates the efficacy and safety of tralokinumab, an IL-13-neutralising antibody, as add-on therapy in adults with moderate-to-severe UC despite standard treatments. DESIGN: Non-hospitalised adults with UC (total Mayo score ≥6) were randomised to receive tralokinumab 300 mg or placebo subcutaneously every 2 weeks for 12 weeks. The primary end point was the rate of clinical response at week 8. Secondary efficacy end points included clinical remission and mucosal healing rates at week 8 and changes in total Mayo score, total modified Riley score, partial Mayo score and disease activity markers. RESULTS: Clinical response rate was 38% (21/56) for tralokinumab vs. 33% (18/55) for placebo (p=0.406). Clinical remission rate was 18% (10/56) vs. 6% (3/55) (p=0.033) and mucosal healing rate was 32% (18/56) vs. 20% (11/55) (p=0.104) for tralokinumab vs placebo. Changes to week 8 in total Mayo score and total modified Riley score were similar for tralokinumab and placebo (least-squares mean difference between groups: -0.49 (p=0.394) and 0.25 (p=0.449), respectively). Partial Mayo score at week 4 was lower with tralokinumab than placebo (least-squares mean difference between groups: -0.90 (p=0.041)). No consistent patterns were observed for disease activity markers. Tralokinumab had an acceptable safety profile. CONCLUSIONS: Add-on therapy with tralokinumab did not significantly improve clinical response. However, the higher clinical remission rate with tralokinumab than placebo suggests that tralokinumab may benefit some patients with UC. Tralokinumab was well tolerated.

Prevention of ulcers by esomeprazole in at-risk patients using non-selective NSAIDs and COX-2 inhibitors.

OBJECTIVES: Proton pump inhibitors reduce ulcer recurrence in non-steroidal anti-inflammatory drug (NSAID) users, but their impact in at-risk ulcer-free patients using the current spectrum of prescribed agents has not been clearly defined. We assessed esomeprazole for ulcer prevention in at-risk patients (> or = 60 yr and/or ulcer history) taking NSAIDs, including COX-2 inhibitors. Such studies are particularly relevant, given that concerns regarding adverse cardiovascular outcomes among COX-2 inhibitor users may prompt re-evaluation of their use. METHODS: We conducted two similar double-blind, placebo-controlled, randomized, multicenter studies; VENUS (United States) and PLUTO (multinational). A total of 844 and 585 patients requiring daily NSAIDs, including COX-2 inhibitors were randomized to receive esomeprazole (20 or 40 mg) or placebo, daily for 6 months. RESULTS: In the VENUS study, the life table estimated proportion of patients who developed ulcers over 6 months (primary variable, intent-to-treat population) was 20.4% on placebo, 5.3% on esomeprazole 20 mg (p < 0.001), and 4.7% on esomeprazole 40 mg (p < 0.0001). In the PLUTO study, the values were 12.3% on placebo, 5.2% with esomeprazole 20 mg (p = 0.018), and 4.4% with esomeprazole 40 mg (p = 0.007). Significant reductions were observed for users of both non-selective NSAIDs and COX-2 inhibitors. Pooled ulcer rates for patients using COX-2 inhibitors (n = 400) were 16.5% on placebo, 0.9% on esomeprazole 20 mg (p < 0.001) and 4.1% on esomeprazole 40 mg (p= 0.002). Esomeprazole was well tolerated and associated with better symptom control than placebo. CONCLUSIONS: For at-risk patients, esomeprazole was effective in preventing ulcers in long-term users of NSAIDs, including COX-2 inhibitors.
