Pharmacokinetics/Pharmacodynamics Biomarker Study in Active Ulcerative Colitis Patients

Phase 2
Completed
Conditions
Colitis, Ulcerative
Interventions
Biological: Anrukinzumab
Other: placebo
Registration Number
NCT01284062
Lead Sponsor
Pfizer
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.

Primary Outcome Measures
NameTimeMethod
Fold Change From Baseline in Fecal Calprotectin at Week 14Baseline, 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
NameTimeMethod
Volume of Distribution (Vz) for AnrukinzumabPre-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.

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.

Number of Participants Who Discontinued From the Study Due to Adverse EventsBaseline up to Week 32
Plasma Decay Half-Life (t1/2) for AnrukinzumabWithin 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.

Maximum Observed Plasma Concentration (Cmax) for AnrukinzumabPre-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).

Minimum Observed Plasma Trough Concentration (Cmin) for AnrukinzumabPre-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).

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

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

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

Area Under the Curve From Time Zero to End of Dosing Interval (AUCtau) for AnrukinzumabPre-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.

Systemic Clearance (CL) for AnrukinzumabPre-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.

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

Total Interleukin-13 (IL-13) LevelBaseline, Day 2, 4, 7, Week 2, 4, 8, 12, 14, 16, 20, 24, 28, 32
