Official title
LUMEN-Dx: Novel Epigenetic Mapping in Cell-Free DNA for the Detection of Lung Cancer
Overview
This trial is a multicenter, open-label, non-interventional controlled study to identify and characterize epigenetic signatures of lung cancer. The goal of this study is to develop a simple blood test that can detect lung cancer with high sensitivity, and assist in the early diagnosis and management of lung cancer. In particular, the ability to assist existing methods in cancer diagnostics, predict response to treatment, and assess the success of treatment during and after treatment will be examined. In addition, the ability to assess minimal residual disease (MRD) will be evaluated, by taking blood after surgery to remove a tumor or after treatment, and testing whether there is any residual DNA from the tumor using the markers that are found. The collection of patients and data will be conducted over a period of about a year and a half, with the aim of reaching approximately 300 participants, including patients with lung cancer before and after treatment/surgery and control groups.
Detailed description
During cell death, which occurs frequently in cancerous tissue, DNA from the dead cells is released into the blood. This DNA has a unique epigenetic pattern that can indicate the tissue of origin from which it was released. Therefore, cell-free DNA may serve as a biomarker for monitoring tissues in which there is increased cell death and allow for early detection of disease before it is even visible by other existing methods. In addition, because the epigenetic pattern is dynamic and changes depending on the existing condition, epigenetic changes may allow the identification of the type of disease or serve as a marker for responsiveness to treatment.
The aim of the proposed study is to perform epigenetic mapping in cell-free DNA to identify genomic regions that differ in their epigenetic pattern between lung cancer patients of all histological types, patients with chronic lung diseases, patients with acute pneumonia, and healthy individuals. In particular, the ability to assist existing methods in cancer diagnostics, predict response to treatment, and assess the success of treatment during and after treatment will be examined. In addition, the ability to assess minimal residual disease (MRD) will be examined by taking blood after surgery to remove a tumor or after treatment and testing whether there is any residual DNA from the tumor using the markers that are found. This method may allow early identification of MRD in lung cancer by cell-free DNA in the blood, thus influencing the method of treatment and significantly increasing the chances of survival for patients.
Subjects will be screened for eligibility and then, after signing an Informed Consent Form, the first peripheral blood sample will be obtained.
Lung cancer patients undergoing treatment will donate blood at the following time points: before starting their first systemic treatment (immunotherapy/chemo-immunotherapy) treatment, 4-12 weeks after treatment initiation, and 6-12 months post-treatment.
Lung cancer patients undergoing surgery to remove lung cancer will donate blood at the following time points: before the surgery, 4-6 weeks after surgery, and 6-12 months post-surgery.
Patients with positive or inconclusive low-dose CT findings and negative biopsy results for lung cancer will be recruited to evaluate the ability of the test to assist in a more accurate diagnosis.
Patients with chronic lung disease or acute pneumonia, with no lung cancer diagnosis and 50 healthy volunteers will be recruited as control groups. These participate will donate blood once during the study.
Primary outcome measures
- Define a set of differential epigenetic biomarkers that uniquely identify lung cancer [Time frame: 12 months from the first blood draw]
