Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This dose comparison study, taking place at over 200 sites worldwide, will compare the dosing, safety and efficacy of an investigational medicine OPC-6535 to the dosing, safety and efficacy of Asacol ® in the maintenance of remission in subjects with ulcerative colitis.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Objective(s):

This study will compare the safety and efficacy of 25 mg per day (QD) and 50 mg QD of OPC-6535 to 800 mg twice a day (BID) of Asacol® in the maintenance of remission in subjects with ulcerative colitis.

Subject Population:

* Subjects with ulcerative colitis currently in remission defined as rectal bleeding (RB) and flexible sigmoidoscopy (FS) scores of 0, on or off a stable dose of sulfasalazine or 5-ASA products for at least 6 weeks.
* Subjects must have had the diagnosis of ulcerative colitis established by prior colonoscopy or undergo colonoscopy in lieu of flexible sigmoidoscopy during the Screening Period.
* Subjects must have had treatment for a flare of ulcerative colitis, with symptomatic onset of remission occurring no more than 52 weeks from the Screening Period.
* Subjects may not have used corticosteroids, topical agents (corticosteroid or 5-ASA enemas, suppositories, foams), azathioprine, 6-mercaptopurine, or methotrexate within 6 weeks of the Screening Period. Upon entry, sulfasalazine and 5-ASA containing products will be discontinued.

Safety: Vital signs, ECGs, laboratory studies (including hematology, clinical chemistry, and urinalysis), and adverse events.
