About this study

Patients who meet all of the inclusion criteria and none of the exclusion criteria are randomized 1:1:1 to receive subcutaneous injections of adalimumab at either 160/80 mg at Week 0/2 and 40 mg every other week (eow) starting at Week 4 to Week 50, 80/40 mg at Week 0/2 and 40 mg eow starting at Week 4 to Week 50, or placebo eow starting at Week 0 to Week 50 under the double-blind condition. At or after Week 8, participants who have inadequate response during the double-blind period can switch to the rescue arm, where participants from the placebo group initially receive adalimumab 160 mg and 80 mg 2 weeks later and those from the adalimumab group receive adalimumab 40 mg initially and 2 weeks later under double-blind conditions. All participants in the rescue arm then receive 40 mg adalimumab eow until Week 50. Participants who complete the 52-week double-blind period receive open-label adalimumab 40 mg eow starting at Week 52 and continuing until the end of the study. Participants who have an inadequate response or disease flare can dose escalate to 80 mg eow at or after Week 60. Participants who dose escalate to 80 mg eow and continue to have an inadequate response or disease flare are withdrawn from the study.

Primary outcomes

  1. Percentage of Participants With Clinical Remission at 8 Weeks

    Time frame: Week 8

    Clinical remission was defined as a Mayo score ≤ 2 with no individual subscore > 1. The Mayo score is a composite score of ulcerative colitis disease activity calculated as the sum of four subscores:

    • Stool Frequency Subscore (SFS), based on the participant's diary and scored from zero (normal number of stools) to three (5 or more stools than normal);
    • Rectal Bleeding Subscore (RBS), based on the participant's diary and scored from zero (no blood) to three (blood only passed);
    • Endoscopy Subscore (ESS), based on colonoscopy or sigmoidoscopy and scored from zero (normal or inactive disease) to three (severe disease, spontaneous bleeding, ulceration);
    • Physician's Global Assessment (PGA) subscore, based on the physician's overall assessment, and scored from zero (normal) to three (severe disease).

    The total Mayo score ranges from 0 to 12 points, with higher scores representing more severe disease.

  2. Percentage of Participants With Clinical Remission at 52 Weeks

    Time frame: Week 52

    Clinical remission was defined as a Mayo score ≤ 2 with no individual subscore > 1. The Mayo score is a composite score of ulcerative colitis disease activity calculated as the sum of four subscores:

    • Stool Frequency Subscore (SFS), based on the participant's diary and scored from zero (normal number of stools) to three (5 or more stools than normal);
    • Rectal Bleeding Subscore (RBS), based on the participant's diary and scored from zero (no blood) to three (blood only passed);
    • Endoscopy Subscore (ESS), based on colonoscopy or sigmoidoscopy and scored from zero (normal or inactive disease) to three (severe disease, spontaneous bleeding, ulceration);
    • Physician's Global Assessment (PGA) subscore, based on the physician's overall assessment, and scored from zero (normal) to three (severe disease).

    The total Mayo score ranges from 0 to 12 points, with higher scores representing more severe disease.

Secondary outcomes

  1. Percentage of Participants With Clinical Remission at 8, 32, and 52 Weeks

    Time frame: Weeks 8, 32, and 52

    Clinical remission was defined as a Mayo score ≤ 2 with no individual subscore > 1. The Mayo score is a composite score of ulcerative colitis disease activity calculated as the sum of four subscores:

    • Stool Frequency Subscore (SFS), based on the participant's diary and scored from zero (normal number of stools) to three (5 or more stools than normal);
    • Rectal Bleeding Subscore (RBS), based on the participant's diary and scored from zero (no blood) to three (blood only passed);
    • Endoscopy Subscore (ESS), based on colonoscopy or sigmoidoscopy and scores from zero (normal or inactive disease) to three (severe disease, spontaneous bleeding, ulceration);
    • Physician's Global Assessment (PGA) subscore, based on the physician's overall assessment, and scored from zero (normal) to three (severe disease).

    The total Mayo score ranges from 0 to 12 points, with higher scores representing more severe disease.

  2. Percentage of Participants With a Clinical Response

    Time frame: Baseline and Weeks 8, 32, and 52

    A clinical response was defined as a decrease in Mayo score of ≥ 3 points and ≥ 30% from Baseline PLUS a decrease in the Rectal Bleeding Subscore (RBS) ≥ 1 or an absolute RBS of 0 or 1.

    The Mayo score is a composite score of ulcerative colitis disease activity calculated as the sum of four subscores:

    • Stool Frequency Subscore, based on the participant's diary and scored from zero (normal number of stools) to three (5 or more stools than normal);
    • Rectal Bleeding Subscore, based on the participant's diary and scored from zero (no blood) to three (blood only passed);
    • Endoscopy Subscore, based on colonoscopy or sigmoidoscopy and scored from zero (normal or inactive disease) to three (severe disease, spontaneous bleeding, ulceration);
    • Physician's Global Assessment subscore, based on the physician's overall assessment, and scored from zero (normal) to three (severe disease).

    The total Mayo score ranges from 0 to 12 points, with higher scores representing more severe disease.

  3. Percentage of Participants With Mucosal Healing

    Time frame: Weeks 8, 32, and 52

    Mucosal healing was defined as an endoscopy subscore of ≤ 1 and was assessed using flexible sigmoidoscopy performed at Weeks 8, 32, and 52.

    The endoscopy subscore ranges from zero to three as follows:

    0 = Normal or inactive disease, 1 = Mild disease (erythema, decreased vascular pattern, mild friability), 2 = Moderate disease (marked erythema, absent vascular pattern, friability, erosions), 3 = Severe disease (spontaneous bleeding, ulceration).

  4. Percentage of Participants With Rectal Bleeding Subscore Indicative of Mild Disease (≤ 1)

    Time frame: Weeks 8, 32, and 52

    Rectal bleeding was assessed from the participant's diary, taking the worst score from the 3 days prior to each study visit. The rectal bleeding subscore ranges from zero to three, according to the following scale:

    0 = no blood seen, 1 = streaks of blood with stool less than half the time, 2 = obvious blood with stool most of the time, 3 = blood alone passed.

  5. Percentage of Participants With Physician's Global Assessment Subscore Indicative of Mild Disease (≤ 1)

    Time frame: Weeks 8, 32, and 52

    The Physician's Global Assessment Subscore acknowledges the three other subscores (Stool Frequency, Rectal Bleeding, and Endoscopy), the participant's daily record of abdominal discomfort and functional assessment, and other observations such as physical findings and the participant's performance status. Possible scores range from zero to three as follows:

    0 = Normal (other subscores are 0), 1 = Mild disease (other subscores are mostly 1), 2 = Moderate disease (other subscores are 1 to 2), 3 = Severe disease (other subscores are 2 to 3).

  6. Percentage of Participants With Stool Frequency Subscore Indicative of Mild Disease (≤ 1)

    Time frame: Weeks 8, 32, and 52

    Stool frequency was assessed from the participant's diary, taking the worst score from the 3 days prior to each study visit. The stool frequency subscore ranges from zero to three, according to the following scale:

    0 = Normal number of stools for this participant, 1 = 1-2 stools more than normal, 2 = 3-4 stools more than normal, 3 = 5 or more stools more than normal.

  7. Percentage of Inflammatory Bowel Disease Questionnaire (IBDQ) Responders

    Time frame: Baseline and Weeks 8, 32, and 52

    An inflammatory bowel disease questionnaire responder was defined as a participant with at least a 16-point increase from Baseline in total Inflammatory Bowel Disease Questionnaire (IBDQ) score. The IBDQ is a 32-item questionnaire consisting of 4 dimensions: bowel-related symptoms, systemic function, social function, and emotional status. The responses to each question within each domain range from 1 (significant impairment) to 7 (no impairment), with the total score ranging from 32 (very poor) to 224 (perfect health-related quality of life).

  8. Number of Participants With Adverse Events up to Week 8

    Time frame: 8 weeks

    An adverse event (AE) is defined as any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment.

    The investigator assessed the relationship of each event to the use of study drug as either probably related, possibly related, probably not related or not related.

    A serious adverse event is an event that results in death, is life-threatening, requires or prolongs hospitalization, results in a congenital anomaly, persistent or significant disability/incapacity or is an important medical event that, based on medical judgment, may jeopardize the participant and may require medical or surgical intervention to prevent any of the outcomes listed above.
