Pharmacokinetics/Pharmacodynamics Biomarker Study in Active Ulcerative Colitis Patients

10. listopadu 2014 aktualizováno: 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.

Clinical Response Rate at Week 14
Časové okno: 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 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.
