Pharmacokinetics/Pharmacodynamics Biomarker Study in Active Ulcerative Colitis Patients
2014年11月10日 更新者:Pfizer
A Phase 2a, Randomized, Double-blind, Sponsor Unblinded, Placebo-controlled, Multiple Dose Study To Evaluate The Pharmacodynamics, Pharmacokinetics And Safety Of Anrukinzumab In Subjects With Active Ulcerative Colitis
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.

Number of Participants With Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs)
時間枠: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.

Clinical Response Rate at Week 14
時間枠: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.

Clinical Remission Rate at Week 14
時間枠: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.
