New study aims to predict dangerous blood clots in cancer patients on chemo
NCT ID NCT07196020
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
Cancer patients face a higher risk of blood clots during chemotherapy, but it's hard to know who is most at risk. This study will measure clotting-related biomarkers in the blood of 380 patients with ovarian, lung, stomach, or pancreatic cancer at four points during their treatment. By comparing those who develop clots with those who don't, researchers hope to develop a blood test that predicts clot risk and helps guide the safe use of blood thinners.
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 lead to a simple blood test that identifies which cancer patients are at high risk of blood clots during chemotherapy, allowing doctors to use blood thinners more safely and effectively.
- What could go wrong
- This is an observational study, not a treatment trial. It is still in early stages and may not produce a reliable prediction tool. The results may not apply to all cancer types or treatments.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Patients with a diagnosis of ovarian, lung, gastric or pancreatic cancer scheduled to undergo a course of chemotherapy who are undergoing adjuvant or neoadjuvant chemotherapy, or who are undergoing chemotherapy for relapsed disease or patients receiving targeted therapy in combination with chemotherapy * Patients who are over 18 years of age * Patients who are able to give full and informed written consent Exclusion Criteria: * Prior history of a documented VTE event within the last 5 years (excluding central line associated events whereby patients completed anticoagulation \> 3 months previously) * Any history of significant haemorrhage (requiring hospitalization or transfusion) outside of a surgical setting within the last 5 years * Familial bleeding diathesis * Known diagnosis of disseminated intravascular coagulation. * Surgery within 2 weeks of first baseline sample (with the exception of porth-a-cath implantation or biopsy) * Chemotherapy or immunotherapy 4 weeks before first baseline sample * Currently receiving long term anticoagulant therapy (Low Molecular Weight Heparin(LMWH), Direct Oral Anticoagulants(DOACs), Warfarin). Patients receiving aspirin, ticlopidine, clopidogrel or LMWH at a prophylactic dosage for a short period (ie post cancer surgery or during short hospital stay) will be included provided they have completed thromboprophylaxis therapy at the first blood sampling time point.
