Point of Care, Real-Time Urine Metabolomics Test to Diagnose Colorectal Cancers and Polyps in Low-and Middle-Income Countries

Summary

Study description: the study is a clinical trial aimed at assessing the validity of a point-of-care tool developed for colorectal cancer screening using urine metabolites.

Objectives:

Primary Objective:

In the pilot phase, investigators will field test the POC device in Nigeria on 75 patients who are high-risk for CRC and then validate the urine metabolite signature using a large cohort of 645 patients at high risk for CRC and polyps. This will allow us to determine the sensitivity and specificity of this device and these signatures for CRC and polyps.

Endpoints: the endpoint will be the calculation of the validity (sensitivity and specificity) of the tool. Positive and negative predictive values will also be calculated.

Study population:

Patients \> 40 years of age with LGI bleeding for more than one-week OR

* Patients who are high risk due to a family history of CRC (first-degree relative)
* Must be at most 10 years younger than when relative presented with CRC (For example, a patient with a relative diagnosed at age 40 with CRC will be eligible after age 30)
* Patients with a diagnosis of stage I-III CRC who have no evidence of disease Both males and females will be involved in the study

I. The study will evaluate the validity and acceptability of the POC biosensor device in Nigeria.

Description of sites/facilities enrolling participants: the study will be conducted at Obafemi Awolowo University Teaching Hospitals Complex (OAUTHC) which hosts the head office of African Research Group for Oncology (ARGO). The study will also run concurrently at other ARGO collaborating sites. All the ARGO collaborating sites are tertiary health care facilities with experienced personnel to oversee the study. The pilot study will, however, take place in OAUTHC alone.

Study duration:

The accrual time for the validation study is 2.5 years. Participant Duration: the study will require initial one-time contact. Those that are positive during the screening with the POC biosensor device will be booked for colonoscopy. Hence, for participants with positive results to complete the study may require 2 weeks on average.

Conditions

• Colorectal Cancer Screening

Interventions

DIAGNOSTIC_TEST

Urine PolypDx machine Versus Colonoscopy

1. Urine samples of the participants in each group will be analyzed to check for preidentified metabolites that signified colorectal cancer 2. Colonoscopy, which is the gold standard for colorectal cancer diagnosis/screening will be performed on all the participants positive for metabolites signifying CRC on Urine PolypDx machine in all the groups
