• Have UC symptoms for at least 3 months prior to Visit 1, and UC diagnosis established by clinical, histological and endoscopic evidence.
• Have active, mild to moderate UC at the time of screening, defined as: - Modified Mayo score 4 - 7, - Mayo endoscopic subscore ≥ 2, confirmed by central reader before randomisation.
• Have a recent (≤ 31 days prior to Visit 1) endoscopy documenting the degree and extent of mucosal inflammation; otherwise, an endoscopy must be performed during the screening period to confirm a MES ≥ 2.
• Currently (at Visit 1) not receiving treatment for ulcerative colitis or receiving oral mesalazine ≤ 3.0g per day or rectal mesalazine ≤ 1.0 g per day (combination of rectal and oral mesalazine is not allowed).
• Be able and willing to avoid all disallowed medications for the appropriate washout period before randomisation and during the rest trial (see Section 7.6 [of D1_Protocol 2023-509606-30-00] for concomitant medications): Medication group, Route, Washout period; Antibiotics, Systemic, 1 week; Anti-diarrhoeal, Systemic, 1 week; Glucocorticoid, Systemic, 4 weeks; Glucocorticoid, Rectal, 4 weeks
