Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Up to 30 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Study population: Patients diagnosed with myeloid disease.

DISEASE CHARACTERISTICS:

  • Samples of blood and tissue cells from patients diagnosed with myeloid disease including the following subtypes:
  • Chronic phase chronic myeloid leukemia (CML), to complement initial studies in the K562 CML cell line
  • Acute promyelocytic leukemia (APL), to complement initial studies in the NB4 APL cell line
  • Acute myeloid leukemia (AML) expressing the t(8;21)(q22;q22) translocation, which occurs in approximately 12% of pediatric AML and is associated with good prognosis
  • AML expressing 5q- or monosomy 7, associated with a poor prognosis
  • AML expressing the fms-like tyrosine kinase 3 internal tandem duplication (FLT3-ITD), associated with a poor prognosis

About this study

Official title: Xenotransplantation of Primary Leukemia Samples Into Zebrafish

RATIONALE: Studying samples of blood and tissue from patients with cancer in the laboratory may help doctors learn more about cancer and the development of drug resistance in patients. It may also help doctors find better ways to treat cancer.

PURPOSE: This research trial is studying samples from patients with leukemia.

Read the detailed description

OBJECTIVES:

  • Demonstrate the capability of primary human leukemia samples to survive and proliferate in the zebrafish embryo.
  • Confirm the anti-proliferative or toxic effects of known chemotherapeutics on the transplanted cells in vivo.
  • Evaluate the effect of novel anticancer drugs and/or their combinations on individual samples.

OUTLINE: This is a multicenter study.

Cryopreserved specimens are injected into the yolk sac of zebrafish embryos under anesthesia. After 1 hour of recovery at 28° C, embryos are maintained at 38° C and screened for fluorescence at the injection site. Within 48 hours post-injection, some embryos are treated with various chemotherapeutic drugs or dimethyl sulfoxide and incubated in protease solution. Proliferation of leukemia cells are monitored by live-cell microscopy. Cells with or without drug treatment are then extracted at 24 and 72 hours post-injection. Leukemia cells are counted and tested with imatinib mesylate, all-trans retinoic acid (tretinoin), cytosine arabinose, and known bioactive chemical compounds from promising drug families, such as tyrosine kinase inhibitors, antiapoptotic agents, channel modulators, and prostaglandin agonists.

Questions about this trial

What is this clinical trial studying?

An observational study of Leukemia, run by Children's 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 19 May 2016. 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?

Primary human leukemia samples capable to survive and proliferate in the zebrafish embryo. The study lists 3 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 19 May 2016.
