E.3 | Principal inclusion criteria |
The patients eligible for inclusion in this study must fulfill all of the following criteria: 1. Written informed consent must be obtained before any assessment is performed. 2. Male and female subjects aged 18-75 years at Screening. 3. Patients diagnosed with UC established at least 3 months prior to screening and history including at least one relapse. 4. Patients with mild to moderate UC which is defined by a total Mayo Score between 5 and 10 (inclusive), comprised of the following subscores; - Endoscopic subscore: 2 or 3 (determined from central reading of screening endoscopy) - Stool frequency subscore: 1-3 - Rectal bleeding subscore: 1-3 - Physician's global assessment subscore: 1-2. 5. Disease must extend beyond 15 cm from the anal verge (assessed by screening endoscopy). 6. Patients must have responded inadequately or have intolerance to conventional therapy with oral 5-ASA prior to screening, and be willing to continue 5-ASA at a stable dose during the study treatment period. 7. Able to communicate well with the investigator, to understand and comply with the requirements of the study. |

E.4 | Principal exclusion criteria |
The patients fulfilling any of the following criteria are not eligible for inclusion in this study: - Use of investigational drugs within 4 weeks or 5 half-lives of screening, whichever is longer; or longer if required by local regulations. - Confirmed laboratory findings at screening showing: • Total white blood cell count (WBC) outside the range of 3,000 – 12,000 /μL. o Subjects with mild leukocytosis (WBC not higher than 15,000 /μL) may be eligible, if the elevated WBC, according to the Investigator, is attributable to disease activity and/or to corticosteroid therapy and other causes such as hematological or infectious diseases can be excluded; • Platelets <100,000/μL; • Hemoglobin <9 g/dL and/or other signs of severe anemia - Are taking any of the prohibited medications listed in Table 6 2 and do not fulfill the washout period at the time of randomization. - Patients receiving concomitant medication(s) that is/are known to inhibit OAT3 or BCRP and that cannot be discontinued or replaced by safe alternative medication within 5 halflives or 1 week (whichever is longer) prior to baseline and for the duration of the study. - Has severe UC during the screening period. - Has previous diagnosis with Crohn's disease, indeterminate colitis, microscopic colitis or acute diverticulitis based on medical history. - Any severe, progressive or uncontrolled medical or psychiatric condition, or other factors at randomization that in the judgment of the investigator prevents the patient from participating in the study. - Active systemic infections (other than common cold) during the 2 weeks prior to randomization. Evidence of Clostridium difficile infection or other intestinal pathogen infection within 4 weeks prior to the first dose of study drug. - History of toxic megacolon, abdominal abscess, symptomatic colonic stricture, or stoma; history or is at risk of colectomy. - Pregnant or nursing (lactating) women, where pregnancy is defined as the state of a female after conception and until the termination of gestation, confirmed by a positive hCG laboratory test at Screening. - Women of child-bearing potential, defined as all women physiologically capable of becoming pregnant, unless they are using basic methods of contraception during dosing of study Treatment. - Patients with clinically relevant primary sclerosing cholangitis
Other protocol-defined exclusion criteria may apply.
