New study tracks hidden blood condition to prevent future disease
NCT ID NCT07313059
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 100 people aged 55 and older who have clonal hematopoiesis (CH) or unexplained low blood counts. Researchers will monitor their health over time, assess risks for heart disease and blood cancers, and provide personalized support. The goal is to create a blueprint for doctors to better care for people with CH and guide future research.
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 study could provide a blueprint for monitoring and managing clonal hematopoiesis, potentially reducing risks of blood cancers and heart disease.
- What could go wrong
- This is an observational study, not a treatment trial. It may not lead to direct medical advances, and results depend on long-term follow-up.

Inclusion Criteria: 1. Aged 55 years and above 2. Confirmed CH or possible CH, with possible CH defined by: a. Persistent, non-severe cytopenia, characterised by one or more of the following, present on at least 2 occasions, at least 4 months apart (WHO criteria): i. Absolute neutrophil count (ANC) \< 1.8 x 109/L ii. Haemoglobin (Hb) \< 120 g/L in females, \< 130 g/L in males iii. Platelet count \< 150 x 109/L 3. Provision of written informed consent prior to any study-related assessments or procedures being carried out. Exclusion Criteria: 1. Severe cytopenia as defined by one or more of the following: 1. ANC \< 0.5 x109/L 2. Hb \< 80 g/L 3. Platelet count \< 50 x 109/L 2. Multilineage cytopenias: a. Marked trilineage cytopenia with all the following present: i. ANC \< 1.0 x 109/L AND ii. Hb \< 110 g/L AND iii. Platelet count \< 100 x 109/L b. Marked bilineage cytopenia, with two or more of the following present: i. ANC \< 1.0 x 109/L ii. Hb \< 110 g/L iii. Platelet count \< 100 x 109/L Note: People with possible CH, with the above characteristics will be excluded from referral to the CH clinic and will instead have urgent investigation as an inpatient or in the haematology clinic. However, if no definite cause for cytopenia is identified, including CH, then individuals may be referred for CH screening at the CH clinic the discretion of the study PI
