Metabolic profiling in chronic lymphocytic leukemia

Official title: Metabolic Profiling of Leukemic Cells Through Isotope Tracing in Patients With CLL

Run by University of Wisconsin, Madison · NCT04785989 · Data updated 2026-11-12

This study is trying to understand how cancer cells in people with chronic lymphocytic leukemia use different fuels to see if it can help find new ways to treat the disease.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with a diagnosis of chronic lymphocytic leukemia, either with low or high disease burden, who are treatment-naïve.

Probably not a fit

Patients with a history of diabetes or those on carbohydrate-restricting diets may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to investigate the metabolic characteristics of chronic lymphocytic leukemia (CLL) by analyzing the fuel preferences and metabolic dependencies of leukemic lymphocytes. Utilizing a 'top-down' approach, the study will employ metabolic tracing techniques with isotopically labeled glucose and glutamine to uncover metabolic vulnerabilities in CLL. The goal is to fill the existing knowledge gap regarding cancer cell metabolism in the human body, which could lead to new therapeutic targets for treatment. Participants will include adults with varying stages of CLL, both treatment-naïve and with specific disease burdens.

Why it matters

Potential benefit: If successful, this study could identify new metabolic targets for treating chronic lymphocytic leukemia, potentially leading to more effective therapies.

How similar studies have gone: While metabolic profiling in cancer is an emerging field, this specific approach to studying CLL metabolism is novel and has not been extensively tested in prior studies.
