About this study

Study M14-675 consists of 2 parts, Part 1 and Part 2. Part 1 is a randomized, double-blind, placebo-controlled 8-week induction period. Part 2 is an open-label, 8-week extended treatment period for participants who did not achieve clinical response at Week 8 in Part 1.

Eligible participants are randomized in a 2:1 ratio to one of the two treatment groups (upadacitinib 45 mg or matching placebo) for 8 weeks. The randomization is stratified by biologic inadequate responder (bio-IR) status (bio-IR vs non-bio-IR), corticosteroid use (yes or no), and Adapted Mayo score (≤ 7 or > 7) at Baseline. Within bio-IR, the randomization is further stratified by number of prior biologic treatments (≤ 1 or > 1). Within non-bio-IR, the randomization is further stratified by previous biologic use (yes or no).

Participants who achieve clinical response defined by Adapted Mayo Score at Week 8 or Week 16 and do not meet any study discontinuation criteria are eligible to enroll into Study M14-234 Substudy 3 (NCT02819635; 52-week maintenance study) or Study M14-533 Cohort 1 (NCT03006068; long-term follow-up study).

Primary outcomes

  1. Percentage of Participants Who Achieved Clinical Remission Per Adapted Mayo Score at Week 8

    Time frame: Week 8

    The Adapted Mayo Score is a composite score of UC disease activity based on the following 3 subscores:

    • Stool frequency subscore (SFS), scored from 0 (normal number of stools) to 3 (5 or more stools more than normal).
    • Rectal bleeding subscore (RBS), scored from 0 (no blood seen) to 3 (blood alone passed).
    • Endoscopic subscore, scored from 0 (normal or inactive disease) to 3 (severe disease, spontaneous bleeding, ulceration).

    The overall Adapted Mayo score ranges from 0 to 9 where higher scores represent more severe disease.

    Clinical remission is defined as an Adapted Mayo score ≤ 2, with SFS ≤ 1 and not higher than Baseline, RBS of 0, and endoscopic subscore ≤ 1.

Secondary outcomes

  1. Percentage of Participants With Endoscopic Improvement at Week 8

    Time frame: Week 8

    Endoscopic improvement is defined as an endoscopic subscore of 0 or 1. Endoscopies were assessed by a blinded central reader and scored according to the following scale: 0 = Normal or inactive disease; 1 = Mild disease (erythema, decreased vascular pattern); 2 = Moderate disease (marked erythema, lack of vascular pattern, any friability, erosions); 3 = Severe disease (spontaneous bleeding, ulceration).

  2. Percentage of Participants With Endoscopic Remission at Week 8

    Time frame: Week 8

    Endoscopic remission is defined as an endoscopic subscore of 0. Endoscopies were assessed by a blinded central reader and scored according to the following scale: 0 = Normal or inactive disease; 1 = Mild disease (erythema, decreased vascular pattern); 2 = Moderate disease (marked erythema, lack of vascular pattern, any friability, erosions); 3 = Severe disease (spontaneous bleeding, ulceration).

  3. Percentage of Participants Who Achieved Clinical Response Per Adapted Mayo Score at Week 8

    Time frame: Week 8

    The Adapted Mayo Score is a composite score of UC disease activity based on the following 3 subscores:

    • Stool frequency subscore (SFS), scored from 0 (normal number of stools) to 3 (5 or more stools more than normal).
    • Rectal bleeding subscore (RBS), scored from 0 (no blood seen) to 3 (blood alone passed).
    • Endoscopic subscore, scored from 0 (normal or inactive disease) to 3 (severe disease with spontaneous bleeding, ulceration).

    The overall Adapted Mayo score ranges from 0 to 9 with higher scores representing more severe disease.

    Clinical response per the Adapted Mayo Score is defined as a decrease in Adapted Mayo score ≥ 2 points and ≥ 30% from Baseline, plus a decrease in RBS ≥ 1 or an absolute RBS ≤ 1.

  4. Percentage of Participants Who Achieved Clinical Response Per Partial Adapted Mayo Score at Week 2

    Time frame: Week 2

    The Partial Adapted Mayo Score is a composite score of UC disease activity based on the following 2 subscores:

    • Stool frequency subscore (SFS), scored from 0 (normal number of stools) to 3 (5 or more stools more than normal).
    • Rectal bleeding subscore (RBS), scored from 0 (no blood seen) to 3 (blood alone passed).

    The overall Partial Adapted Mayo score ranges from 0 to 6 with higher scores representing more severe disease.

    Clinical response per Partial Adapted Mayo Score is defined as a decrease in Partial Adapted Mayo score ≥ 1 point and ≥ 30% from Baseline, plus a decrease in RBS ≥ 1 or an absolute RBS ≤ 1.

  5. Percentage Of Participants Who Achieved Histologic-Endoscopic Mucosal Improvement at Week 8

    Time frame: Week 8

    Histologic endoscopic mucosal improvement is defined as an endoscopic subscore of 0 or 1 and a Geboes score ≤ 3.1.

    The endoscopic subscore ranges from 0 (normal or inactive disease) to 3 (severe disease with spontaneous bleeding, ulceration).

    The Geboes histologic index includes seven histological features (architectural change, chronic inflammatory infiltrate, lamina propria neutrophils and eosinophils, neutrophils in epithelium, crypt destruction and erosion or ulcers). The Geboes score has 6 grades, each with 3-5 subgrades: Grade 0, structural change only; Grade 1, chronic inflammation; Grade 2, lamina propria neutrophils and eosinophils; Grade 3, neutrophils in epithelium; Grade 4, crypt destruction; and Grade 5, erosions or ulceration.

  6. Percentage of Participants Who Reported No Bowel Urgency at Week 8

    Time frame: Week 8

    Bowel urgency was assessed by participants in a subject diary completed once a day.

  7. Percentage of Participants Who Reported No Abdominal Pain at Week 8

    Time frame: Week 8

    Abdominal pain was assessed by participants in a subject diary completed once a day.

  8. Percentage of Participants Who Achieved Histologic Improvement at Week 8

    Time frame: Week 8

    Histologic improvement is defined as a decrease from Baseline in Geboes score. The Geboes histologic index includes seven histological features (architectural change, chronic inflammatory infiltrate, lamina propria neutrophils and eosinophils, neutrophils in epithelium, crypt destruction and erosion or ulcers). The Geboes score has 6 grades, each with 3-5 subgrades: Grade 0, structural change only; Grade 1, chronic inflammation; Grade 2, lamina propria neutrophils and eosinophils; Grade 3, neutrophils in epithelium; Grade 4, crypt destruction; and Grade 5, erosions or ulceration.

  9. Change From Baseline in Inflammatory Bowel Disease Questionnaire (IBDQ) Total Score at Week 8

    Time frame: Baseline (Week 0) to Week 8

    The Inflammatory Bowel Disease Questionnaire (IBDQ) is used to assess health-related quality of life (HRQoL) in patients with ulcerative colitis. It consists of 32 questions evaluating bowel and systemic symptoms, as well as emotional and social functions. Each question is answered on a scale from 1 (worst) to 7 (best). The total score ranges from 32 to 224 with higher scores indicating better health-related quality of life. A positive change from Baseline indicates improvement.

  10. Percentage of Participants Who Achieved Mucosal Healing at Week 8

    Time frame: Week 8

    Mucosal healing is defined as an endoscopic score of 0 and Geboes score < 2.0. The endoscopic subscore ranges from 0 (normal or inactive disease) to 3 (severe disease with spontaneous bleeding, ulceration).

    The Geboes histologic index includes seven histological features (architectural change, chronic inflammatory infiltrate, lamina propria neutrophils and eosinophils, neutrophils in epithelium, crypt destruction and erosion or ulcers). The Geboes score has 6 grades, each with 3-5 subgrades: Grade 0, structural change only; Grade 1, chronic inflammation; Grade 2, lamina propria neutrophils and eosinophils; Grade 3, neutrophils in epithelium; Grade 4, crypt destruction; and Grade 5, erosions or ulceration.

  11. Change From Baseline in Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) Score at Week 8

    Time frame: Baseline (Week 0) to Week 8

    The FACIT fatigue questionnaire was developed to assess fatigue associated with anemia. It consists of 13 fatigue-related questions. Each question is answered on a 5-point Likert scale: 0 (not at all); 1 (a little bit); 2 (somewhat); 3 (quite a bit); and 4 (very much). The total score ranges from 0 to 52, where higher scores represent less fatigue, and a positive change from Baseline indicates improvement.
