- Clinical Utility of ctDNA in Detecting Resistance Mechanisms and Delivering Precision Medicine to Cancer Patients — Recruiting • Non-phase study • Oncology • NCT07673861.
- What is being tested: The clinical utility of circulating tumour DNA (ctDNA) analysis from blood samples to detect cancer resistance mechanisms and guide precision medicine treatment decisions, rather than relying solely on tissue biopsies.
- Patient eligibility overview: The trial includes cancer patients across various tumour types where ctDNA analysis can be performed on blood samples; specific eligibility criteria would depend on cancer stage, prior treatment history, and measurable ctDNA presence.

ctDNA stands for circulating tumour DNA. As ctDNA is released by tumour cells into the blood stream, taking a blood sample and analysing it for ctDNA, can provide a lot of useful information about a patient's cancer. In certain situations, ctDNA can be used to screen for or detect cancer early, to aid clinical decisions about which treatment to give a patient, to provide information about if a cancer has become resistant to treatment, or provide information about how much cancer may be left after treatment (residual disease). The aim…
