Clinical Trial TitleBESPOKE Study of ctDNA Guided Therapy in Colorectal Cancer
National Clinical Trial Number:NCT0426470
Clinical Trial Protocol Description:
Subjects are being asked to participate in this study because subjects are over the age of 18, and subjects have been diagnosed with either stage II or III colorectal cancer and have undergone surgery or will shortly undergo surgery. Subject and subject’s doctor have decided subject will have Signatera™ ctDNA testing performed as part of subject’s routine care. Signatera is a laboratory test that uses DNA from a tissue sample to measure tumor DNA in the blood. This is an observational study, which means it will not change the regular medical care subjects will receive from subject’s doctor. The study is being done to better understand how Signatera results are used to manage care of patients with colorectal cancer. The test that will be used for ctDNA (circulating tumor DNA) testing is a diagnostic test called Signatera. The test can only be used in the certified laboratory that developed the test. Subject and subject’s doctor have decided subject will have Signatera ctDNA testing performed as part of subject’s routine care.
Patients will receive SIGNATERATM test results and may be recommended for chemotherapy or observation by their treating healthcare provider (HCP). Patients will be followed for up to two (2) years with periodic whole blood collection. Treatment administered, disease-free survival, overall survival, time to recurrence, physician questionnaires and patient-reported outcomes will be collected/recorded.
