About

This is a prospective, multicenter, double-blind (DB), controlled, randomized, parallel group comparison Phase 3a study to evaluate the efficacy and safety of new mesalamine suppositories (MAX-002) as compared to placebo and active medicine after 6 weeks of treatment in adults with mild to moderate ulcerative proctitis (UP).

Full description

The present study consists of screening period (2 weeks before randomization), DB phase (6 weeks), OL phase (8 weeks) and follow-up visits at Week 3, Week 6 and Week 14. Participants who are eligible will be randomized to receive 1g MAX-002, 1g Canasa® and placebo suppository once daily in the DB phase. Participants who complete or discontinue the study at Week 6 will either receive 1g MAX-002 suppositories on a voluntary basis, standard care treatment as per investigator's discretion or no treatment during the next 8 weeks of the OL phase. Total duration of treatment will be of 14 weeks. Efficacy will primarily be evaluated by percentage of participants who show response as per Mayo DAI Score at Week 6. Participants' safety will be monitored throughout the study.
