Simple blood tests could help monitor cancer treatment progress
NCT ID NCT05708599
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is collecting blood samples from 102 patients with non-small cell lung cancer, colorectal cancer, or pancreatic cancer who are receiving standard treatments. Researchers will analyze the blood for cancer DNA (ctDNA) to see how it changes over time and whether it relates to tumor response. The goal is to find better ways to monitor cancer using a simple blood test instead of repeated biopsies.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors use simple blood tests to monitor how well cancer treatments are working and detect changes early.
- What could go wrong
- This is an observational study, not a treatment trial. It only looks at blood samples and does not test any new drug or therapy, so it cannot directly improve patient outcomes.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. ≥18 years old 2. Male or female patients with pancreatic ductal adenocarcinoma, colorectal carcinoma or adenocarcinoma of the lung as specified above leading to new treatment line. 3. Signed and dated written informed consent in accordance with International Council on Harmonisation-Good Clinical Practice (ICH-GCP) and local legislation prior to admission to the study. 4. Willingness to undergo pre- and on-treatment liquid biopsies for biomarker assessment. Patients can be enrolled without tissue tumour biopsy upon agreement between the Investigator and the Sponsor. Exclusion Criteria: 1. Patients not expected to comply with the protocol requirements or not expected to complete the study as scheduled (e.g. chronic alcohol or drug abuse or any other condition that, in the investigator's opinion, makes the patient an unreliable study participant). 2. Women who are pregnant or who plan to become pregnant during the study. 3. Participation at a clinical trial involving an investigational medicine where the treatment details cannot be disclosed.
