EQUAL: EGFR ctDNA QUantative Assessment for Lung Cancer Screening in Asian and Latinx Populations

NCT ID: NCT06716580Sponsor: Dana-Farber Cancer InstituteLast updated: 2025-12-10

Summary

This research study is studying a new blood test to screen for Epidermal Growth Factor Receptor (EGFR) positive lung cancer in healthy individuals at risk for the disease and who cannot undergo regular lung cancer screening. The name of the test used in this research study is: -Circulating free DNA (cfDNA) Assay

Detailed description

The goal of this research study is to evaluate the feasibility of a novel EGFR blood plasma ctDNA screening test among East Asian and Latinx participants at risk for lung cancer and ineligible for regular lung cancer screening. The test looks for a gene change called Epidermal Growth Factor Receptor (EGFR), specifically EGFR L858R and exon 19 deletions, which comprise 85-90% of total EGFR mutations. This study seeks to determine if it is possible to use the blood test to detect this type of lung cancer that might not yet show symptoms. The research study procedures include screening for eligibility, in-clinic visits, blood tests, and an optional questionnaire and/or focus group. It is expected that about 1000 people will participate in the blood sample collection, 100 individuals in the survey, and 20 individuals in the focus groups.

Arms & interventions

DeviceCirculating Tumor DNA (ctDNA) Assay
Screening investigational blood test to test for EGFR L858R and exon 19 deletions, which comprise 85-90% of total EGFR mutations. A positive or indeterminate investigational test will be followed up by CLIA verification of results. A positive or indeterminate CLIA result will be followed up by a lung CT scan. A positive CT scan will be followed up by referral for further evaluation. A negative CT scan will be followed up by a repeat scan in 12 months.

Outcome measures

Detection Rate of Non-Small Cell Lung Cancer
The proportion of participants with a positive assay result who are subsequently diagnosed with lung cancer through clinical pathology, among all participants tested with the assay.
