The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details.
Collaborator:
University of Alberta
Information provided by (Responsible Party):
Mebo Research, Inc.
  Purpose
The purpose of this study is to identify metabolic signatures associated with malodor conditions. The investigators will perform state-of-the art metabolomics tests and bioinformatic data mining to explore if conditions leading to malodor can be screened by metabolomic profiling of urine samples.

Condition
Nutritional and Metabolic Diseases

Study Type: Observational
Study Design: Observational Model: Case-Control
Time Perspective: Prospective
Official Title: Metabolomic Profiling of Urine Samples for the Identification of Novel Biomarkers and Mechanisms in the Diagnosis and Management of Malodor Associated With Metabolic Inefficiencies

Further study details as provided by Mebo Research, Inc.:

Primary Outcome Measures:
  • Differences in metabolite concentrations measured by mass spectrometry, comparing urine samples from individuals with malodor issues, and age-matched healthy controls. [ Time Frame: ten months ]
    The investigators would like to validate if urine metabolomic profiling can be used for identifying key metabolomic signatures associated with malodor


Secondary Outcome Measures:
  • Correlations between urine biomarkers and frequency/severity of malodor symptoms (questionnaires) [ Time Frame: one year ]
    The investigators will comprehensively analyze the ability of metabolite levels to discriminate frequent and severe from non-severe malodor symptoms


Enrollment: 54
Actual Study Start Date: February 2016
Estimated Study Completion Date: May 2018
Primary Completion Date: August 30, 2017 (Final data collection date for primary outcome measure)
Groups/Cohorts
Subjects with malodor
individuals with self-reported odor issues suspected to be associated with microbial imbalance on or inside the body and inefficient metabolism as evidenced from other laboratory tests
Healthy control
individuals not complaining of uncontrollable or unpredictable malodor episodes

Detailed Description:
In this study, metabolite profiling analysis will be carried out on urine samples of individuals with malodor conditions related to metabolism inefficiencies. Metabolic profiles will be identified using the metabolomics equipment located in the NMR, HPLC and MS facilities of the Metabolomics Innovation Centre (TMIC). Multivariate statistical analyses will be used, as well as other approaches to mine complex data from heterogeneous sources.
