About this study
Official title: Genome Wide Association Study Evaluating Genetic Factors Related to the Efficacy and Tolerability of Fludarabine Treatment in Patients With CLL
RATIONALE: Studying samples of DNA in the laboratory from patients who received fludarabine-based treatment may help doctors learn more about the effects of fludarabine on cells. It may also help doctors understand how well patients respond to treatment.
PURPOSE: This research study is studying DNA samples from patients with chronic lymphocytic leukemia previously treated with fludarabine-based therapy.
Read the detailed description
OBJECTIVES:
- To identify genetic characteristics associated with the efficacy and toxicity of fludarabine-based treatment in patients with chronic lymphocytic leukemia who participated on E2997.
- To validate these genetic characteristics with a cancer cell model system to confirm association and dissect the mechanism of effect.
OUTLINE: Archived DNA samples are analyzed for genetic characteristics associated with the efficacy and toxicity to fludarabine-based treatment using Affymetrix 6.0 single nucleotide polymorphism arrays. The results are then compared with data of genes identified in a cancer cell model system, and with clinical data (response, toxicity, overall survival, and progression-free survival) associated with each patient sample.

Questions about this trial
What is this clinical trial studying?
An observational study of Leukemia, run by Eastern Cooperative Oncology Group.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
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 17 May 2017. 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?
Association of single SNP genotype with overall and progression-free survival (time frame: 1 month). 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 17 May 2017.
