Brief summary

To evaluate the long-term safety and tolerability of encapsulated mesalamine Granules (eMG) (formerly referred to as Mesalamine Pellets \[MP\]) in participants with ulcerative colitis currently in remission.

Detailed description

This is a Phase 3, multicenter, open-label, treatment extension study evaluating the long-term safety and tolerability of eMG given once daily (QD) in participants who successfully participated in a double-blind lead-in study (MPUC3003 \[NCT00744016 \] or MPUC3004 \[NCT00767728 \]) or new participants who are currently in remission from symptoms of ulcerative colitis.

Inclusion criteria

1. An Institutional Review Board (IRB)/Ethics Committee (EC) approved informed consent is signed and dated prior to any study-related activities. 2. Participant has successfully participated in a previous MP clinical study per investigator's discretion with successful participation minimally defined as compliant with study-related procedures and study drug dosing schedule in the previous study and did not discontinue from the previous study due to study drug-related AE(s) or if new participants: a. Participant is a male or, If the participant is female, she is eligible to enter if she is of: Non-childbearing potential (that is; physiologically incapable of becoming pregnant, including any female who has undergone sterilization \[hysterectomy or bilateral tubal ligation\] or is post-menopausal. For purposes of this study, postmenopausal is defined as 1 year without menses); or childbearing potential, has a negative serum pregnancy test at screen and, if heterosexually active, agrees to one of the following: i) Double barrier method of contraception, specifically, use of a condom and spermicide, for 1 week prior to study drug administration, throughout the 6-month Treatment Phase, and the 2-week follow-up phase. ii) Oral contraceptives administered for at least 2 monthly cycles prior to study drug administration during all 6 months of study drug administration and administered for 1 monthly cycle following completion of the study. iii) An intrauterine device (IUD), inserted by a qualified clinician, with published data showing that the lowest expected failure rate is less than (\<)1% per year (not all IUDs meet this criterion). iv) Medroxyprogesterone acetate (DEPO-PROVERA) administered for a minimum of 1 monthly cycle prior to the study drug administration, during all 6 months of study drug administration, and administered for 1 monthly cycle following study completion. Norelgestromin/ ethinyl estradiol transdermal system (Ortho Evra patch) administered for at least 2 monthly cycles prior to study drug administration and administered for 2 monthly cycles following study completion. v) Partner has undergone vasectomy and participant is in a monogamous relationship. The investigator is responsible for determining whether the participant has adequate birth control for study participation. b. Participant is greater than or equal to (≥) 18 years of age. c. Participant has historically confirmed diagnosis (physician letter for newly/recently diagnosed and by medical records for previously diagnosed participants) of mild to moderate UC in remission for greater than (\>) 1 month and \<12 months. d. Confirmed current remission defined as both: A screening rectal bleeding score of 0 as described in the Disease Activity Index (DAI) (Sutherland Index) where 0 = None A screening sigmoidoscopy score of 0 to 1 for mucosal appearance as described in the (Sutherland Index where 0 = intact mucosa with preserved or distorted vessels and 1 = Erythema, decreased vascular pattern, granularity, no mucosal hemorrhage. 3. Participant and investigator consider there is the potential for benefit to the participant with MP treatment. 4. Participant is capable and willing to comply with all study procedures.

Exclusion criteria

1. Participant has any condition or circumstance that would, in the opinion of the investigator, prevent completion of the study or interfere with analysis of study results, including history of noncompliance with treatments or visits. If a new participant, the following additional
