- Diagnostic Test: Circulating Tumor Deoxyribonucleic acid (ctDNA) Assay
- Registration Number
- NCT07096362
- Lead Sponsor
- University of Miami
- Brief Summary
The purpose of this study is to understand whether a blood-based test called circulating tumor DNA (ctDNA) can detect whether participants are having a desired tumor shrinkage or an undesired lack of tumor shrinkage, and to study whether these levels of ctDNA can be used to make treatment decisions faster than the current standard approach, which is to wait 8 weeks after starting chemotherapy to obtain participant first imaging scans since starting chemotherapy.

- Primary Outcome Measures
Name Time Method Part 1:Change in ctDNA fold-change at Week 4 Baseline, Up to 4 weeks (after intervention) Circulating tumor Deoxyribonucleic Acid (ctDNA) fold-change at week 4 is defined as the ratio between ctDNA quantity at week 4 relative to baseline. The quantity of ctDNA will be measured in ng/mL.
At week 4 among participants in Part 1 will be reported as a Tumor Methylation Score (TMS) in plasma samples. The ratio between the TMS at week 4 (TMS4) and the TMS at baseline (TMS0) will be calculated.Part 1: Number of Radiographic Response Status Responders vs. Number of Non-Responders Up to 1.5 years (after intervention) Radiographic response status among participants in Part 1 will be reported in numbers. Participants will undergo Positron Emission Tomography/Computed Tomography (PET/CT) radiographic imaging scans at the end of week 8. Participants will be subdivided into two groups: responders vs. non-responders to modified Folfirinox treatment. Responders will be defined as the number of participants achieving complete response (CR), partial response (PR) or exhibiting stable disease (SD). Non-responders will be defined as the number of participants exhibiting progressive disease (PD). Response will be evaluated using Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 criteria.
Part 2: Progression-Free Survival (PFS) Up to 3.5 years (after intervention) Progression-Free Survival (PFS) is defined as elapsed time in months from day 1 of starting second-line (2L) chemotherapy until the date of documented progressive disease (PD) or death.
- Secondary Outcome Measures
Name Time Method Part 1: Change in ctDNA Tumor Methylation Score (TMS) Baseline, Up to 8 weeks (after intervention) Circulating tumor Deoxyribonucleic Acid (ctDNA) Tumor Methylation Score (TMS) is defined as the amount of methylated tumor DNA in the blood. ctDNA TMS will be assessed at baseline, weeks 2, 4, 6, and 8.
The Tumor Methylation Score (TMS) score ranges from 10 to 1,000,000. TMS is proprietary score, it does not have units.Part 1: Number of Radiographic Responses Up to 8 weeks (after intervention) The number of radiographic response among participants in Part 2 will be reported as the result of Positron Emission Tomography/Computed Tomography (PET/CT) radiographic imaging scans taken at the end of week 8. Response will be evaluated using Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 criteria.
Part 2: Overall Survival (OS) Up to 3.5 years (after intervention) Overall Survival (OS) is defined as elapsed time in months from start of first-line (1L) mFOLFIRINOX treatment to date of death.
