Subjects must fulfil one of the following criteria: Inadequate response: signs and symptoms of persistently active disease despite induction treatment at the approved induction dosing that was indicated in the product label at the time of use Loss of response: recurrence of signs and symptoms of active disease during approved maintenance dosing following prior clinical benefit (discontinuation despite clinical benefit does not quality as having failed or being intolerant to UC biological therapy or JAK inhibitor) Intolerance: history of intolerance to infliximab, adalimumab, golimumab, vedolizumab, ustekinumab, tofacitinib or other approved biologicals or JAK inhibitors (including but not limited to infusion-related event, demyelination, congestive heart failure, or any other drug-related adverse event that led to a reduction in dose or discontinuation of the medication) 107 If receiving any of the following therapies, subjects must have stable dosage for the specified duration: 5-aminosalicylates (ASAs), stable dosage for at least 2 weeks prior to screening endoscopy Oral corticosteroids: prednisone up to 20 mg/day or its equivalent, stable dose for 2 weeks prior to screening endoscopy Budesonide: extended release tablets 9 mg/day [budensonide MMX], stable dose for at least 2 weeks prior to screening endoscopy Conventional immunomodulators: azathioprine, 6-mercaptopurine, methotrexate, stable dosage for at least 8 weeks prior to screening endoscopy |
