This study has 3 treatment phases, a 12-Week Induction Phase, a 40-Week Maintenance Phase, and a 48-Week Extension Phase.

The objective is to evaluate the efficacy and safety of obefazimod compared to placebo as induction and maintenance therapy in subjects with moderately to severely active CD after inadequate response (no response, loss of response, or intolerance) to conventional therapies and/or advanced therapies.

The primary objective for the 48-Week Extension Phase is to evaluate the safety and tolerability of obefazimod compared with placebo in subjects who are enrolled in the Extension Phase.

This is a study to learn if the experimental medicine (called PF-07054894) is safe, effective, and how it is processed in adult people with ulcers in the colon.

This is a multicenter, randomized, placebo controlled study to evaluate the efficacy and safety of ABX464 given at 25 or 50 mg QD in inducing clinical remission 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 \[biologics (TNF inhibitors, anti-integrins, anti-IL-23), and/or S1P receptor modulators, and/or JAK inhibitors\].
