About this study

Determine P-glycoprotein expression in blood samples of Acute Lymphocytic leukemia (ALL) pediatric patients receiving MTX treatment and trace its ontogeny and compare it with its expression in pediatric healthy subjects. In addition, to determine the correlation of P-glycoprotein expression and Methotrexate concentration at steady state.

Read the detailed description

The 20 leukemic patients will be classified into three age groups according to the ages that will be available at the time of sample collection.

  • All patients will be recruited from Tanta Oncology Center, Tanta University.
  • The study will be approved by the Research Ethics Committee of Tanta University and college of Pharmacy ethical committee.
  • An informed consent will be obtained from parents of all patients in this research before enrollment.
  • All patients' data will be private and confidential. Any unexpected risks that may appear during the course of the research will be reported to patients and the ethical committee on time.

Blood Samples will be obtained from healthy pediatric subjects of the same ages of the diseased group subjects (Samples will be obtained from subjects from a primary care center during their routine blood analysis excluding patients of chronic diseases, patients receiving any medications, and patients of impaired kidney or liver functions).

P-glycoprotein expression will be estimated in all samples using Permeability glycoprotein (P-gp), ELISA Kit, and its expression will be traced with development from the youngest till the oldest age available, this will also be compared with normal healthy pediatric subjects.

Being tested
MTX, (but the investigator is not using any intervention, the participants are already taking it in their treatment protocol and the investigator is just analyzing p-gp expression)
Medical subject headings
Precursor Cell Lymphoblastic Leukemia-Lymphoma

Questions about this trial

What is this clinical trial studying?

An observational study of Acute Lymphocytic Leukemia, run by Tanta University at 3 sites in Egypt.

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 3 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: finished, as of the sponsor's last update on 2 Sep 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in Egypt. 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?

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?

P-gp expression in blood samples (time frame: 42 hours). 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?

On the ClinicalTrials.gov record for NCT05021159, which also lists 3 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 2 Sep 2021.
