About this study
Official title: Molecular Mechanisms of NOTCH Induced Transformation in T-ALL
RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.
PURPOSE: This laboratory study is looking at tissue samples from patients with T-cell acute lymphoblastic leukemia.
Read the detailed description
OBJECTIVES:
- Identify the transcriptional signatures associated with the presence of NOTCH1 mutations in primary T-cell acute lymphoblastic leukemia (T-ALL) cells using oligonucleotide microarrays.
- Characterize the global changes on gene expression resulting from the inactivation of NOTCH signaling in human T-ALL lymphoblasts.
OUTLINE: This is a multicenter study.
Frozen lymphoblast samples from patients with T-cell acute lymphoblastic leukemia (NOTCH1-mutated and wild type) are assessed for genetic expression profiles and mutations by microarray analysis and activated NOTCH1 protein by western blot analysis.
PROJECTED ACCRUAL: A total of 48 samples from patients will be accrued for this study.

Questions about this trial
What is this clinical trial studying?
An observational study of Leukemia, run by ECOG-ACRIN Cancer Research Group.
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 0 inclusion and 1 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 5 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?
Transcriptional signatures associated with NOTCH1 mutations in T-cell acute lymphoblastic leukemia (T-ALL) cells (time frame: 1 month). 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?
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 5 Feb 2020.
