Primary

Measure	Time frame
Main Objective: The primary objective of the study is to evaluate the long-term safety of ABX464 given at 50 mg once daily in subjects with Moderate to Severe Active Ulcerative Colitis.;Secondary Objective: The secondary objectives are to evaluate: • The long-term effect of ABX464 on clinical and endoscopic remission in subjects with Moderate to Severe Active Ulcerative Colitis assessed by the MCS. • The long-term effect of ABX464 on inflammatory markers (CRP, Calprotectin and ESR) • The long-term of ABX464 on Quality of Life (QoL) measured by the SF- 36 questionnaire in subjects with Moderate to Severe Active Ulcerative Colitis.;Primary end point(s): Number of incidences of treatment-emergent adverse events in ABX464 treated subjects.;Timepoint(s) of evaluation of this end point: Timepoint of evaluation of this end point from day 0 to EoS.	—
