ctDNA Assay in Patients With Resectable Pancreatic Cancer

Официальное название

Application of ctDNA Assay in the Neoadjuvant and Adjuvant Chemotherapy Setting in Patients With Resectable Pancreatic Cancer

Обзор

The purpose of this study is to determine the proportion of positive ctDNA -freely circulating tumor DNA fragments found in the blood plasma- in patients with pancreatic cancer and to better understand the relationship between possible ctDNA biomarkers and patient survival. A successful study may provide preliminary evidence that helps improve future patient care through targeted diagnostics, prognosis, and/or treatment.

Подробное описание

The objective of this study is to assess the role of serial ctDNA analysis as integrative biomarker in patients with resectable or borderline resectable pancreatic cancer undergoing treatment with curative intent. This is a single arm prospective tissue/blood collection from patients undergoing neoadjuvant treatment and Surgery as well as surveillance, plan to accrue up to 50 patients. Primary objective is to determine the proportion of ctDNA positive in patients with resectable pancreatic cancer and to evaluate the progression free survival (PFS) in subjects with ctDNA positive versus ctDNA negative.

Patients who consent to the study will participate in pre-study exams and tests to find out if they can take part in the study. This includes, but is not limited to, a doctor's visit with medical history and physical evaluation, blood work, pregnancy test for those capable of becoming pregnant, and imaging tests.

The study itself will include the patient's regular treatment for pancreatic cancer which may include 4 to 6 months of chemotherapy, chemo-radiation, surgery to remove pancreatic cancer, 24 weeks of post operative ctDNA surveillance and follow up for 2 years. Blood will be drawn at regular time points during this study for ctDNA detection. The tumor tissue at diagnosis will be collected to develop a personalized and tumor informed PCR test.
