About this study

  1. To assess the incidence of IDH1 and IDH2 mutations in adult AML patients, and to explore their associations with the patients' clinical, cytogenetic, and molecular characteristics as well as with treatment response and outcome.
  2. To delineate the similarities and distinctions among mutations at IDH1-R132, IDH2-R140 and IDH2-R172 in AML, both clinically and molecularly (including cytogenetics, immunophenotyping, mutation co-occurrence patterns).
  3. The results can be references for future selection of targeted therapy (targeting IDH mutant proteins).
Read the detailed description

Isocitrate dehydrogenases (IDH) are enzymes that catalyze oxidative decarboxylation of isocitrate into alpha-ketoglutarate (α-KG). IDH1 and IDH2 mutations in AML give the enzymes neomorphic enzymatic activity to transform α-KG to D-2HG, an oncometabolite which acts as a competitive inhibitor of dioxygenases, and causes dysregulation of TET2 and histone demethylases, consequently leading to epigenetic reprogramming of a cell, blocking differentiation and contributing to a transformed phenotype, and leukemogenesis. Investigators plan to recruit 300 adult AML patients (newly diagnosed or relapsed). 10mL of peripheral blood or marrow blood will be obtained from routine practice blood/marrow sampling specimens (no extra venipuncture or bone marrow aspiration would be required) and sent for routine tests such as cytogenetics, immunophenotyping, and gene mutation analyses. IDH1 R132, IDH2 R140, and IDH2 R172 mutations will be screened by PCR followed by Sanger sequencing, as previously described.

Investigators will first assess the incidence of IDH1 and IDH2 mutations in adult AML patients, and then explore their associations with the patients' clinical course, cytogenetic, and molecular characteristics as well as with treatment response and outcome. Investigators also seek to delineate the similarities and distinctions among IDH mutation variants at IDH1-R132, IDH2-R140 and IDH2-R172, both clinically and molecularly (including cytogenetics, immunophenotyping, mutation co-occurrence patterns).

What is being measured

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

  1. Incidence of IDH1 and IDH2 mutation

    Peripheral blood or marrow blood will be obtained from routine practice blood/marrow sampling specimens (no extra venipuncture or bone marrow aspiration would be required) and sent for routine tests such as cytogenetics, immunophenotyping, and gene mutation analyses.

    Measured: 2017/03/07 - 2019/03/01

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Myeloid Leukemia, run by National Taiwan University Hospital at 1 site in Taiwan.

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 2 inclusion and 2 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: status not confirmed, as of the sponsor's last update on 20 Apr 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Results are not available in the source record.

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

Contact Wen-Chien Chou (0972651701, wchou@ntu.edu.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of IDH1 and IDH2 mutation (time frame: 2017/03/07 - 2019/03/01). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 20 Apr 2018.
