About this study
Official title: A Randomized, Double Blind, Multiple Dose Placebo Controlled Study to Evaluate the Safety, Tolerability, and Efficacy of AMG 181 in Subjects With Moderate to Severe Ulcerative Colitis
The primary objective of this study is to evaluate the effect of abrilumab on induction of remission in adults with moderate to severe ulcerative colitis after 8 weeks of treatment as assessed by a total Mayo Score ≤ 2 points, with no individual subscore > 1 point.
Read the detailed description
The study consisted of a 24-week double-blind, placebo-controlled treatment period followed by an open-label period of approximately 108 weeks. Participants were eligible to enter the open-label period of the study early if they did not achieve a response at week 8 and had an inadequate response at week 12 or later or if they experienced disease worsening after achieving response and/or remission at week 8. Failure to achieve response at week 8 was defined as failure to achieve a decrease from baseline in total Mayo Score ≥ 3 points and ≥ 30% decrease from baseline. Inadequate response at week 12 or later was defined as failure to achieve a 2-point decrease and 25% improvement in partial Mayo Score compared with screening and minimum partial Mayo Score ≥ 5 points. Disease worsening was defined as an increase in partial Mayo Score ≥ 3 points from the week 8 value and minimum partial Mayo Score ≥ 5 points with recto-sigmoidoscopy sub-score ≥ 2.
Participants were planned to be randomized in a 2:1:2:2:2 ratio to placebo or abrilumab at 7 mg, 21 mg, 70 mg (on day 1, week 2, week 4, and every 4 weeks thereafter until week 24), or 210 mg (on day 1 followed by placebo in weeks 2 and 4 and every 4 weeks thereafter until week 24), respectively. Due to a consistent discrepancy between the investigational product (IP) instruction manual (IPIM) description of vial positions and the actual vial positions in the IP package participants were initially randomized to 3 arms (placebo, 70 mg, and 210 mg) with a randomization ratio of 4:3:2. The study was temporarily paused while this issue was investigated. Once the discrepancy was corrected, Protocol Amendment 3 implemented, and affected participants completed their double-blind treatment period, the study resumed enrollment and randomization per protocol. Neither the randomization nor study blind was compromised and therefore the intent-to-treat principle was maintained.

What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants With Remission at Week 8
Remission was defined as a total Mayo Score ≤ 2 points, with no individual subscore > 1 point.
The Mayo Score is a composite index of four items (stool frequency, rectal bleeding, rectosigmoidoscopy findings, and physician's global assessment) with each item graded semi-quantitatively on a score of 0 to 3 where 0 represents normal and higher score represents more severe disease status. The total Mayo Score is the sum of the four item scores, with a result ranging from 0 to 12 points. Higher scores represent more severe disease.
The remission rate (percentage of participants with remission) was calculated based on observed data (unadjusted remission rate) and also after applying a logistic regression model including the factors of treatment group, stratification factors (prior anti-TNF use and pre- versus post-Protocol Amendment 3) and baseline total Mayo Score (adjusted remission rate).
Measured: Week 8
Secondary outcomes (3)
Percentage of Participants With Response at Week 8
Response was defined by a decrease from baseline in the total Mayo Score of ≥ 3 points and ≥ 30%, with an accompanying decrease in the rectal bleeding subscore ≥ 1 point or an absolute rectal bleeding subscore = 0 or 1.
The Mayo Score is a composite index of four items (stool frequency, rectal bleeding, rectosigmoidoscopy findings, and physician's global assessment), each graded semi-quantitatively on a scale of 0 to 3 where 0 represents normal and higher score represents more severe disease status. The total Mayo Score is the sum of the four item scores, ranging from 0 to 12 points. Higher scores represent more severe disease.
The response rate (percentage of participants with response) was calculated based on observed data (unadjusted response rate) and also after applying a logistic regression model including the factors of treatment group, stratification factors (prior anti-TNF use and pre- versus post-Protocol Amendment 3) and baseline total Mayo Score (adjusted response rate).
Measured: Baseline and week 8
Percentage of Participants With Mucosal Healing at Week 8
Mucosal healing was defined using the rectosigmoidoscopy subscore of Mayo assessment as absolute subscore for rectosigmoidoscopy of 0 or 1.
Flexible rectosigmoidoscopy was performed as part of the Mayo assessment, graded semi-quantitatively on a scale of 0 to 3 where 0 represents normal and higher score represents more severe disease status.
The healing rate (percentage of participants with mucosal healing) was calculated based on observed data (unadjusted healing rate) and also after applying a logistic regression model including the factors of treatment group, stratification factors (prior anti-TNF use and pre- versus post-Protocol Amendment 3) and baseline rectosigmoidoscopy score (adjusted healing rate).
Measured: Week 8
Percentage of Participants With Sustained Remission at Week 8 and Week 24
Remission was defined as a total Mayo Score ≤ 2 points, with no individual subscore > 1 point. Sustained remission was defined as achieving the criteria for remission at both week 8 and week 24.
The Mayo Score is a composite index of four items (stool frequency, rectal bleeding, rectosigmoidoscopy findings, and physician's global assessment), each graded semi-quantitatively on a scale of 0 to 3 where 0 represents normal and higher scores represent more severe disease status. The total Mayo Score is the sum of the four item scores, with a and ranges from 0 to 12 points. Higher scores represent more severe disease.
The remission rate (percentage of participants with sustained remission) was calculated based on observed data (unadjusted remission rate) and also after applying a logistic regression model including the factors of treatment group, stratification factors (prior anti-TNF use and pre- versus post-Protocol Amendment 3) and baseline total Mayo Score (adjusted remission rate).
Measured: Week 8 and week 24

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of Participants With Remission at Week 8 (time frame: Week 8). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT01694485, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 27 Jun 2019.
