Brief Summary  

This is a multicenter, randomized, blinded study to evaluate the long-term efficacy and safety of ABX464 50mg and 25mg administered once daily (QD) as maintenance therapy following completion of 8-week induction treatment (Induction Studies ABX464-105 or ABX464-106) in subjects with moderately to severely active ulcerative colitis who have inadequate response, no response, a loss of response, or an intolerance to either conventional therapies [corticosteroids, immunosuppressant (i.e. azathioprine, 6-mercaptopurine, methotrexate)] and/or advanced therapies [biologics (TNF inhibitors, anti-integrins, anti-IL-23), and/or S1P receptor modulators, and/or JAK inhibitors].

This study is the maintenance phase of the Phase 3 clinical development program sequential to previous induction studies ABX464-105 and ABX464-106.

All eligible subjects who have completed either one of the induction studies above mentioned, will be encouraged to take part in the present ABX464-107 maintenance study and will be randomized to either a double blind, placebo-controlled part (Part #1) or allocated to ABX464 50mg or 25mg blinded ABX464 treatment arms (Part #2) depending on their clinical response at the end of induction as shown below.

This study consists of a 44-week treatment phase and a 28-days follow-up period concluding in the End of Study (EOS) visit.
