Evaluation of the ctDNA LUNAR Test in an Average Patient Screening Episode — ECLIPSE  

Colorectal Cancer Clinical Trial

Official title: Evaluation of the ctDNA LUNAR Test in an Average Patient Screening Episode

Status Active, not recruiting

Clinical Trial Summary

The ECLIPSE (Evaluation of the ctDNA LUNAR test in an Average Patient Screening Episode) study is a prospective, observational multi-site study without randomization. The primary objective of the study is to evaluate the performance characteristics of a blood-based ctDNA LUNAR-2 test to detect colorectal cancer in a screen-relevant, average risk population.

Clinical Trial Description

The LUNAR-2 test has been developed to detect malignant disease in screen-relevant patients who would otherwise undergo screening for malignant disease using invasive methodologies such as colonoscopy. The intended use of such a test would be to return a result of ctDNA detected/ ctDNA not detected in a patient eligible for average risk screening for colorectal cancer. Those patients who receive a ctDNA detected result should undergo further investigation with colonoscopy. In order to define the performance characteristics of the test in a relevant population, this study will perform a blood draw prior to the patient undergoing the standard of care colonoscopy (and all associated preparatory medications) and retrospectively compare the performance characteristics of the LUNAR-2 test with the findings of the index colonoscopy. Outcomes of patients at one and two-years post-procedure will be collected as secondary endpoints to investigate the possibility of incidental, non-colorectal cancer cases and interval cancers that had not reached the clinical threshold for detection at the time of the index colonoscopy. ;
