  • Confirmed diagnosis of UC for at least 3 months prior to Screening.
  • Active UC with a modified Mayo Score of 5 to 9 points and Mayo Endoscopic Subscore of 2 to 3 at Screening (historical endoscopy within 3 months of screening).

If no data are available, an endoscopy will be performed at Screening.
  • Average daily very soft or liquid stool frequency ≥4.0 and/or average daily abdominal pain score ≥2.0 at Screening.
