             d. Confirmed current remission defined as both: A screening rectal bleeding score of 0
             as described in the Disease Activity Index (DAI) (Sutherland Index) where 0 = None A
             screening sigmoidoscopy score of 0 to 1 for mucosal appearance as described in the
             (Sutherland Index where 0 = intact mucosa with preserved or distorted vessels and 1 =
             Erythema, decreased vascular pattern, granularity, no mucosal hemorrhage.

          3. Participant and investigator consider there is the potential for benefit to the
