Official title: Tumor Cell and DNA Detection in the Peripheral Blood of Patients With Hematological Malignancy

Run by University of Missouri-Columbia · NCT04841447 · Data updated 2026-11-12

This study is testing if a medication that blocks DPP-4 can help prevent relapse in people with acute myeloid leukemia by looking at their blood and bone marrow.

What this trial studies

This observational study aims to collect blood and bone marrow specimens from patients with hematological malignancies to understand the effects of Dipeptidyl Peptidase-4 (DPP-4) inhibitors on acute myeloid leukemia (AML) stem cells. The research will explore how DPP-4 contributes to leukemia development and the potential for individualized therapies. By testing DPP-4 inhibitors both in vitro and in vivo, the study seeks to determine if these inhibitors can prevent AML relapse during remission. The findings may provide insights into new treatment strategies for AML and other related blood cancers.

Why it matters

Potential benefit: If successful, this study could lead to more effective, individualized therapies for patients with leukemia.

How similar studies have gone: While the role of DPP-4 in leukemia has been explored in animal models, this study represents a novel approach using human samples to investigate its implications in hematological malignancies.
