Multidrug Resistance Genes in Patients With Acute Myeloid Leukemia
An observational study of Leukemia, run by Alliance for Clinical Trials in Oncology at 1 site in United States.
Trial summary
This research trial studies multidrug resistance genes in patients with acute myeloid leukemia. Studying samples of bone marrow or blood from patients with cancer in the laboratory may help doctors learn more about changes that may occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer.

About this study
Official title: Multidrug Resistance Protein Gene Polymorphisms in Acute Myeloid Leukemia. A CALGB Leukemia Tissue Bank Project
This research trial studies multidrug resistance genes in patients with acute myeloid leukemia. Studying samples of bone marrow or blood from patients with cancer in the laboratory may help doctors learn more about changes that may occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer. It may also help doctors learn more about drug resistance and how patients respond to treatment.

PRIMARY OBJECTIVES:
- To investigate the association of common single nucleotide polymorphisms (SNPs) and haplotypes of the three multidrug resistance (MDR) genes with treatment outcome in the clinical studies.
II. To assess the effect of ATP-binding cassette (ABC) B1, ABCC1, and ABCG2 polymorphisms and haplotypes on treatment outcome in younger patients enrolled on Cancer and Leukemia Group B (CALGB) 9621 and 19808.
III. To assess the effect of ABCB1, ABCC1, and ABCG2 polymorphisms and haplotypes on treatment outcome in older patients enrolled on CALGB 9720.
SECONDARY OBJECTIVES:
- To test the hypothesis that ABCB1, ABCC1, and ABCG2 polymorphisms and haplotypes are associated with phosphoglycolate phosphatase (Pgp), multidrug resistance protein 1 (MRP-1), and ATP-binding cassette, sub-family G (WHITE), member 2 (Junior blood group) (BCRP) function and expression in pre-treatment blasts from acute myeloid leukemia (AML) patients.
II. To assess the effect of ABCB1, ABCC1, and ABCG2 polymorphisms and haplotypes on PGP, MRP-1, and BCRP function through CALGB 9760 in younger patients enrolled on CALGB 9621 and 19808.
III. To assess the effect of ABCB1, ABCC1, and ABCG2 polymorphisms and haplotypes on PGP, MRP-1, and BCRP function through CALGB 9760 in older patients from CALGB 9720.
IV. To conduct an exploratory analysis of the association of additional candidate genes relevant to etoposide, cytarabine, and daunorubicin with chemotherapy response and toxicity.
OUTLINE:
Leukemia blast cells obtained from bone marrow aspirate or peripheral blood at diagnosis are used to study polymorphisms and haplotypes of ATP-binding cassette (ABC) B1, ABCC1, ABCG2, and other candidate genes. Multidrug resistance (MDR) protein expression and function are also analyzed using leukemia blast cells from patients enrolled on CALGB-9760.
PROJECTED ACCRUAL: Tissue samples from over 600 patients will be accrued for this study.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This research trial studies multidrug resistance genes in patients with acute myeloid leukemia. Studying samples of bone marrow or blood from patients with cancer in the laboratory may help doctors learn more about changes that may occur in deoxyribonucleic acid (DNA) and identify biomarkers related to cancer. It may also help doctors learn more about drug resistance and how patients respond to treatment.

Questions about this trial
What is this clinical trial studying?
An observational study of Leukemia, run by Alliance for Clinical Trials in Oncology at 1 site in United States.
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: under way, not looking for participants, as of the sponsor's last update on 18 Aug 2023. 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 United States. 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?
This study is still under way. Results are not available in the source record yet.
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?
Correlation of common single nucleotide polymorphisms (SNPs) and haplotypes of the 3 multidrug resistance genes (P-glycoprotein [Pgp], multidrug resistance-associated protein (MRP-1) and breast cancer resistance protein [BCRP]) with treatment outcome (time frame: Baseline). 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 18 Aug 2023.
