Run by Meir Medical Center · NCT05882175 · Data updated 2026-11-12

This study is testing a new index to see if it can help doctors better understand and predict outcomes for patients with blood cancers who might develop a serious condition called HLH.

Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 18 and older with newly diagnosed or transformed hematologic malignancies.

Probably not a fit

Patients who have received recent treatment for their hematologic malignancy within the last month may not benefit from this study.

What this trial studies

This study aims to validate the Optimized HLH Inflammatory (OHI) index in patients with hematologic malignancies who may develop hemophagocytic lymphohistiocytosis (HLH). It will enroll patients with new or transformed hematologic malignancies and follow them to assess their survival and prognosis over one year. The OHI index is based on specific biomarkers, including elevated levels of soluble CD25 and ferritin, which may help in diagnosing and predicting outcomes for patients with this serious condition.

Why it matters

Potential benefit: If successful, this study could improve diagnostic accuracy and prognostic assessment for patients with HLH associated with hematologic malignancies.

How similar studies have gone: While the OHI index is a novel approach, similar studies have shown the importance of biomarkers in improving outcomes for patients with HLH.
