About this study

Official title: Analysis of T Cell Metabolism and Immune Phenotype During the Course of Acute Myeloid Leukemia

The objective of this study was to analyze the T cell metabolism and immune phenotype in AML patients during the course of the disease before and after allo-HCT.

Read the detailed description

Patients who experience relapse of acute myeloid leukemia (AML) after allogeneic hematopoietic cell transplantation (allo-HCT) have a dismal prognosis. Infusion of donor T cells can induce graft-versus-leukemia (GVL) effects, indicating the importance of intact T cell function for leukemia control. Recent studies have shown the importance of metabolic fitness for an effective T cell response.

In this study we have analyzed the T cell metabolism and immune phenotype in AML patients at different time points before and after allo-HCT.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. T cell metabolism

    Extracellular acidification rate (ECAR) and oxygen consumption rate (OCR) determined by live-cell metabolic assay using the Seahorse Analyzer

    Measured: 4 years

  2. T cell phenotype

    T cell cytokine and effector molecule production

    Measured: 4 years

Secondary outcomes (1)
  1. Metabolite abundance in serum

    Serum metabolites as measured by mass spectrometry

    Measured: 4 years

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Myeloid Leukemia, run by University of Freiburg.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Feb 2020. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

T cell metabolism (time frame: 4 years). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04259372, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Feb 2020.
