• Patients who receive mMS score of 8 or greater (severe disease)
• Patients with known allergy to study drugs or have a history of serious AEs related to their use.
• Patients who 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.

• Any condition which the Investigator judges to preclude safe participation in the study or to confound the evaluation of the study outcome.
• Uncontrolled hypertension (defined as systolic ≥140 mmHg or diastolic ≥90 mmHg) despite optimal antihypertensive treatment at screening. If blood pressure is out of range, up to 2 repeated assessments are permitted no more than 60 minutes apart.

Laborértékek

• Patients who are currently using potassium sparing diuretics

Egyéb

• Presence of enteric pathogens or Clostridium difficile toxins in stool samples.
• Patients not able to withdraw from treatment or need continuing immunosuppressants for example sirolimus or cyclosporine during the study period.
• Patients with hyperkalemia
• Positive pregnancy test or lactating patients.
• Patients with history or evidence of chemical substance abuse.

• Male and female patients ≥ 18 years and ≤ 65 years of age.
• Patients have a documented history of idiopathic ulcerative colitis based on standard endoscopic (colonoscopic) and histological criteria involving the whole or part of the left side of the colon [approximately 60 cm up from the anus (anal verge) to splenic flexure of colon], with mild to moderate active disease.
• Patients with a score of at least 4 on the modified Mayo Score (mMS), including an endoscopy subscore of at least 2 and a rectal bleeding subscore of at least 1.
• Patients who have inadequate response, loss of response, or intolerance of at least 1 of aminosalicylates (5-ASAs) (mesalamine, sulfasalazine, olsalazine, basalazide), corticosteroids, azothiopurine, mercaptopurine and methotrexate and need an alternative therapy as per the discretion of the Investigator.
• Patients who have failed to achieve total resolution of all symptoms to topical and/or oral standard treatment regimen of aminosalicylates (mesalamine, sulfasalazine, olsalazine, basalazide) or corticosteroids, azathioprine, mercaptopurine and methotrexate over minimum 4-week duration and need an alternative therapy as per the discretion of the Investigator. Determination of the outcomes of prior therapies should be made after the completion of at least one induction regimen and one maintenance regimen, as appropriate, for the prior therapy.
• The patients who do not show evidence of benefits with the use of Biologics (e.g. Anti-integrins, Anti-TNFalpha and Anti-interleukins) for ulcerative colitis can be enrolled in the study. However, after a washout duration of 5 half-lives from any prior biologic treatments prior to enrollment is required. A shorter washout duration (e.g., 3 half-lives) is acceptable if undetectable drug levels of the biologic can be demonstrated.
  • Note: Absence of benefit (inadequate response) is defined as signs and symptoms of persistently active disease despite an adequate trial of induction treatment with an anti-TNF-α agent (per country's approved label); OR recurrence of symptoms during maintenance dosing following prior clinical benefit;
• A female participant is eligible to participate if she is not pregnant or breastfeeding, and at least one of the following conditions applies:
  • Is not a woman of childbearing potential (WOCBP) OR
  • Is a WOCBP and agrees to remain on an acceptable contraceptive method that is highly effective (with a failure rate of <1% per year), preferably with low user dependency when used consistently and correctly during the intervention period and for at least 6 weeks after the last dose of study intervention. The investigator should evaluate the effectiveness and the potential for contraceptive method failure (e.g., noncompliance, recently initiated) of the contraceptive method in relationship to the first dose of study intervention.
  • A WOCBP must have a negative pregnancy test (serum) at screening and a negative pregnancy test (urine) before the first dose of study intervention.
  • Note: The investigator is responsible for review of medical history, menstrual history, and recent sexual activity to decrease the risk for inclusion of a woman with an early undetected pregnancy.
• Male participants are eligible to participate if they agree to the following during the intervention period and for at least 6 weeks after the last dose of study intervention:
  • Must agree not to donate sperm for the purpose of reproduction
  • PLUS EITHER OF B or C:
  • Be abstinent from heterosexual intercourse as their preferred and usual lifestyle (abstinent on a long-term and persistent basis) and agree to remain abstinent OR
  • Must agree to use contraception /barrier as detailed below
  • A male participant must wear a condom when engaging in any activity that allows for passage of ejaculate to another person.
  • Male participants should also be advised of the benefit for a female partner to use a highly effective method of contraception as condom may break or leak when having sexual intercourse with a woman of childbearing potential who is not currently pregnant
• Patient can understand and sign a written informed consent form, which must be obtained prior to initiation of study procedures.
• Patients with adequate vitals, hematologic, liver and renal function at screening visit
• If drugs such as aminosalicylates (e.g., mesalamine, sulfasalazine, olsalazine, balsalazide) or corticosteroids, azothiopurine, mercaptopurine and methotrexate recently discontinued, they must have been stopped for at least 2 weeks (for aminosalicylates, and corticosteroids)/8-week duration (for azathioprine, mercaptopurine, and methotrexate) prior to the endoscopy used for baseline modified Mayo Score (mMS).
• For 30 patients undergoing intensive PK substudy:
  • Agree to undergo PK sampling procedure.
  • Participant having adequate venous access.
