| Summary: | Background:
Mesalamine suppositories are first‐line therapy in active ulcerative proctitis; the standard regime still recommends multiple doses per day. The primary objective of this study was to show the noninferiority of once‐daily administration of a novel 1 g mesalamine suppository versus thrice‐daily administration of the 0.5 g mesalamine suppository.
Methods:
This was a single‐blind (investigator‐blinded), randomized, multicenter, comparative, Phase III clinical trial. Patients with mild to moderately active ulcerative proctitis inserted either one mesalamine 1 g suppository at bedtime or one mesalamine 0.5 g suppository thrice daily over a 6‐week period. The primary endpoint was rate of remission (Disease Activity Index below 4).
Results:
In all, 354 patients were evaluable for safety and per‐protocol analysis. The new regimen demonstrated noninferiority: The percentage of patients with remission was 87.9% for the once‐daily 1 g mesalamine suppository and 90.7% for the thrice‐daily 0.5 g mesalamine suppository. Each regimen resulted in prompt cessation of clinical symptoms (e.g., median time to ≤3 stools per day (all without blood): 5 days in the 1 g mesalamine once‐daily and 7 days in the 0.5 g mesalamine thrice‐daily group). Patients preferred applying suppositories once a day.
Conclusions:
In active ulcerative proctitis the once‐daily administration of a 1 g mesalamine suppository is as effective and safe, yet considerably more convenient, than the standard thrice‐daily administration of a 0.5 g mesalamine suppository. (Inflamm Bowel Dis 2010) |
