Study Description

Brief Summary

This study represents the first investigation of anrukinzumab in patients with active ulcerative colitis (UC) and will evaluate proof of mechanism by changes in the mechanism based biomarker (YKL 40) and pharmacodynamic biomarkers (fecal calprotectin, lactoferrin and hs-CRP). It will provide further assessment of the safety, tolerability, and pharmacokinetics (PK) by administration of multiple intravenous (IV) doses of anrukinzumab.

    Outcome Measures

    Primary Outcome Measures

    1. Fold Change From Baseline in Fecal Calprotectin at Week 14 [Baseline, Week 14]

      The fold change from baseline in fecal calprotectin at Week 14, is the ratio of the measurement of fecal calprotectin at Week 14 to baseline measurement; this was calculated as the change from baseline in natural log transformed fecal calprotectin at Week 14.

    Secondary Outcome Measures

    1. Maximum Observed Plasma Concentration (Cmax) for Anrukinzumab [Pre-dose to end of the dosing interval after Day 1, Week 12]

      Maximum concentration observed during the dosing interval (2 weeks for day 1, 4 weeks for week 12).

    2. Minimum Observed Plasma Trough Concentration (Cmin) for Anrukinzumab [Pre-dose to end of the dosing interval after Day 1, Week 12]

      Lowest concentration observed during the dosing interval (2 weeks for day 1, 4 weeks for week 12).

    3. Area Under the Curve From Time Zero to End of Dosing Interval (AUCtau) for Anrukinzumab [Pre-dose, within 1 hour post-end of infusion on Day 1; Day 2, 4, 7, pre-dose on Week 2]

      Area under the plasma concentration curve from time zero to end of dosing interval (2 weeks) was reported.

    4. Plasma Decay Half-Life (t1/2) for Anrukinzumab [Within 1 hour post-end of infusion on Week 12; Week 14, 16, 18, 20, 22, 24, 26, 28, 30, 32]

      Plasma decay half-life is the time measured for the plasma concentration to decrease by one half.

    5. Systemic Clearance (CL) for Anrukinzumab [Pre-dose, within 1 hour post-end of infusion on Week 12; Week 14, 16, 18, 20, 22, 24, 26, 28, 30, 32]

      CL is a quantitative measure of the rate at which a drug substance is removed from the body.

    6. Volume of Distribution (Vz) for Anrukinzumab [Pre-dose, within 1 hour post-end of infusion on Week 12; Week 14, 16, 18, 20, 22, 24, 26, 28, 30, 32]

      Volume of distribution is defined as the theoretical volume in which the total amount of drug would need to be uniformly distributed to produce the desired plasma concentration of a drug.

    7. Fold Change From Baseline in Fecal Calprotectin at Week 2, 4, 8 and 12 [Baseline, Week 2, 4, 8, 12]

      The fold change from baseline in fecal calprotectin at post-baseline visit, is the ratio of the measurement of fecal calprotectin at post-baseline visit to baseline measurement; this was calculated as the change from baseline in natural log transformed fecal calprotectin at post-baseline visit.

    8. Total Interleukin-13 (IL-13) Level [Baseline, Day 2, 4, 7, Week 2, 4, 8, 12, 14, 16, 20, 24, 28, 32]

    9. Number of Participants With Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) [Baseline up to Week 32]

      An AE was any untoward medical occurrence in a participant who received study drug without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes or deemed significant for any other reason: death; initial or prolonged inpatient hospitalization; life-threatening experience (immediate risk of dying); persistent or significant disability/incapacity; congenital anomaly. Treatment-emergent are events between first dose of study drug and up to Week 32 that were absent before treatment or that worsened relative to pretreatment state. All causality AEs included SAEs as well as non-serious AEs, without regard to relationship to the study drug, which occurred during the trial.

    10. Number of Participants Who Discontinued From the Study Due to Adverse Events [Baseline up to Week 32]

    11. Number of Participants With Anti-drug Antibody (ADA) and Neutralizing Antibody [Day 1, Week 4, 8, 12, 14, 16, 20, 24, 28, 32]

      Neutralizing antibody was not analyzed as no participant had positive ADA samples.

    12. Number of Participants With Change From Baseline in Endoscopic Subscore at Week 14 [Baseline, Week 14]

      Mayo score is used to measure the disease activity of ulcerative colitis. Endoscopy or flexible sigmoidoscopy is a sub score of Mayo score. The score for endoscopic subscore ranges from 0 to 3, where higher score indicates more severe disease activity. Participant's score for endoscopy or flexible sigmoidoscopy at Week 14 was specified as improved (decrease), no change and worsened (increase) compared to their baseline score.

    Other Outcome Measures

    1. Clinical Response Rate at Week 14 [Week 14]

      Clinical response rate is defined as percentage of participants with at least 3 point decrease from baseline in total Mayo score with at least 30% change along with 1 point decrease from baseline or absolute score of 0 or 1 in rectal bleeding. The Mayo score is a tool designed to measure disease activity for ulcerative colitis. The Mayo score ranges from 0 to 12 points and consists of 4 subscores (stool frequency, rectal bleeding, findings on flexible sigmoidoscopy [endoscopy] and physician's global assessment), each subscore is graded from 0 to 3 with the higher score indicating more severe disease activity.

    2. Clinical Remission Rate at Week 14 [Week 14]

      Clinical remission rate is defined as percentage of participants with a total Mayo score less than or equal to 2, with no individual subscore greater than 1 at post baseline visit. The Mayo score is a tool designed to measure disease activity for ulcerative colitis. The Mayo score ranges from 0 to 12 points and consists of 4 subscores (stool frequency, rectal bleeding, findings on flexible sigmoidoscopy and physician's global assessment), each subscore is graded from 0 to 3 with the higher score indicating more severe disease activity.

    3. Change From Baseline in Total Mayo Score at Week 14 [Baseline, Week 14]

      The Mayo score is a tool designed to measure disease activity for ulcerative colitis. The Mayo score ranges from 0 to 12 points and consists of 4 subscores (stool frequency, rectal bleeding, findings on flexible sigmoidoscopy [endoscopy] and physician's global assessment), each subscore is graded from 0 to 3 with the higher score indicating more severe disease activity.

    4. Number of Participants With Change From Baseline in Stool Frequency at Week 14 [Baseline, Week 14]

      Stool frequency is a sub score of Mayo score used to measure the disease activity of ulcerative colitis. The score for stool frequency ranges from 0 to 3, where higher score indicates more severe disease activity. Participant's score for stool frequency at Week 14 was specified as improved (decrease), no change and worsened (increase) compared to their baseline score.

    5. Number of Participants With Change From Baseline in Rectal Bleeding at Week 14 [Baseline, Week 14]

      Mayo score is used to measure the disease activity of ulcerative colitis. Rectal bleeding is a sub score of Mayo score.
