Official title
COLOMATE: Colorectal Cancer Liquid Biopsy Screening Protocol for Molecularly Assigned Therapy
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This trial screens patients with colon or rectal cancer that has spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable) for genetic mutations for recommendation to a molecularly assigned therapy. Identifying gene mutations may help patients enroll onto target companion trials that target these mutations.
