Study of the Safety and Efficacy of Zoenasa® Versus Mesalamine Enema in Subjects With Left-Sided Ulcerative Colitis
This study is ongoing, but not recruiting participants.

This double-blind, randomized, comparator-controlled Phase II study is designed to establish the safety and efficacy of Zoenasa Rectal Gel compared to mesalamine enema in subjects with left-sided ulcerative colitis, as measured by the modified ulcerative colitis disease activity index (UCDAI), over 6 weeks of treatment. In this study, two cohorts of subjects will receive either Zoenasa-1:4 (1.0g NAC; 4.0g 5-ASA) investigational drug enema therapy or comparator mesalamine enema (4.0g 5-ASA). The study will enroll subjects randomized equally into the 2 cohorts. Each cohort will enroll approximately 60 subjects. The two arms of the trial will be enrolled concurrently in a randomized fashion.

- Female subjects of childbearing potential must have a negative urine pregnancy test at screening; surgically sterile, post-menopausal, abstinent, or patient or partner agree to use a medically appropriate form of birth control from screening to until 1 month after the last dose of study medication.
- Male subjects must be surgically sterile, abstinent, or patient or partner compliant with a contraceptive regimen from screening to until 1 month after the last dose of study medication.
- They are able to understand and sign a written informed consent form, which must be obtained prior to initiation of study procedures.
- They have documented history of proximal or universal ulcerative colitis, proctitis or active proctitis confined to 15cm or less from the anal verge.
- They demonstrate signs and symptoms of fulminant colitis, bowel stricture, toxic megacolon, an anticipated need for blood transfusion for gastrointestinal bleeding, or demonstrate evidence of peritonitis.
