Read the detailed description
Acute leukemias are clonal malignant diseases of immature hematopoietic system ,characterized by clonal evolution and considerable genetic, epigenetic, and phenotypic heterogeneity,and constitute a common cause of morbidity and mortality worldwide.[1] Gene expression profiling has improved the molecular classification and prognosis of Acute leukemias, where molecular testing has become mandatory for further classify into prognostic groups. Among the genetic aberrations, alterations of the FMS-like tyrosine kinase 3 (FLT3) gene. [2] FLT3 is a type 3 receptor tyrosine kinase that plays an important role in the expansion and proliferation of multi-potent progenitor cells within the bone marrow.[3] mutations of FLT3 induce a constitutional activation of tyrosine kinases and several downstream targets resulting in proliferation and growth of malignant cells ,myeloproliferative phenotype , high tumor burden,and a characteristic hematological , immunophenotypic and biochemical profile that can be identified during routine diagnostic workup.[4]Two mutations exist in these cells: FLT3-ITD (internal tandem duplication), and FLT3-TKD, a point mutation in the tyrosine kinase domain.[5] FLT3-ITD is a common driver mutation, seen with a frequency of 20 to 30% ,and significantly affecting the pathogenesis and the clinical outcome . Genetic testing for FLT3-ITD mutation at diagnosis is done to risk stratify patients and to guide therapeutic decisions.[6-8] FLT3 receptor/CD135 is a transmembrane tyrosine kinase receptor, normally expressed on the surface of hematopoietic stem cells and is lost upon cell differentiation , activation of the receptor resulting in stimulating survival and proliferation, and inhibiting apoptosis of progenitor cells . Overexpression of the FLT3 receptor has been reported to be associated with high risk for relapse in patients with acute leukemia .[2]

Questions about this trial
What is this clinical trial studying?
An observational study of Acute Myeloid Leukemia, run by Assiut University.
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 1 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: status not confirmed, as of the sponsor's last update on 19 May 2022. 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?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Shaimaa Abdelazeem Selim, Assist. lecturer (01006214247, Shaimaaselim95@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Correlation between FLT3 gene mutation and the expression of CD135 and their association with clinical outcome ,haematological, immunophenotypic , biochemical characteristics in the development and progression of AML. (time frame: baseline). 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 NCT05383014, which also lists 6 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 19 May 2022.
