Urinary Prostaglandin E Metabolite (PGE-M), A Metabolite of Prostaglandin E2 (PGE2): A Novel Biomarker of Crohn's Disease Activity

This study has been completed.

Collaborator:
UCB Pharma
Information provided by (Responsible Party):
David Schwartz, Vanderbilt University Medical Center
ClinicalTrials.gov Identifier:
NCT00496548
First received: July 2, 2007
Last updated: April 30, 2017
Last verified: April 2017
  Purpose
The purpose of this study is to determine whether urinary PGE-M levels correlate with Crohn's disease activity and to compare how well urinary PGE-M correlates with other non-invasive biomarkers of disease activity such as C-reactive protein (CRP) and fecal calprotectin.

Condition Intervention

Procedure: Fecal calprotectin
Procedure: Urinary PGE-M Level

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: No masking
Primary Purpose: Diagnostic

Primary Outcome Measures:
  • Urine for PGE-M levels [ Time Frame: Day of colonoscopy procedure ]

Secondary Outcome Measures:
  • Blood for C-reactive protein (CRP) levels [ Time Frame: Day 1 ]
  • Stool for fecal calprotectin [ Time Frame: Prior to colonoscopy procedure (before beginning bowel prep) ]
  • Routine colonoscopy for assessment of disease activity [ Time Frame: 1-3 weeks from consent ]
  • Harvey-Bradshaw index disease activity score [ Time Frame: Day of colonoscopy procedure ]

Enrollment: 159
Study Start Date: August 2007
Study Completion Date: December 2015
Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
Fecal calprotectin and urinary PGE-M levels will be tested on all participants.
Procedure: Fecal calprotectin
Fecal calprotectin levels obtained and compared to urinary PGE-M and serum C-reactive protein (CRP) levels.
Procedure: Urinary PGE-M Level
Urinary PGE-M level obtained and compared to fecal calprotectin and serum CRP levels.

Detailed Description:

The available clinical measures of Crohn's disease activity can be overly influenced by functional symptoms. Placebo response rates in clinical trials are high. Several non-invasive biomarkers are currently available for assessing inflammatory bowel disease (IBD) disease activity including erythrocyte sedimentation rate, C-reactive protein and fecal calprotectin. Although these markers hold some promise, their performance is less than ideal. What is needed is a simple, non-invasive, biologic measure of Crohn's disease.

Cyclooxygenase-2 (COX-2) is involved in prostaglandin E2 (PGE2) synthesis and is expressed in epithelial inflammatory conditions and some cancers. We have developed an assay to quantify the major urinary metabolite of PGE2, PGE-M. PGE-M has been previously shown to be elevated in the urine of patients with advanced colorectal neoplasia relative to controls.
