About this study
Official title: Immunotherapy With ex Vivo Expanded Haploidentical Natural Killer Cells as Consolidation Strategy for Children/Young Adults With AML
The purpose of this study is to estimate the efficacy of immunotherapy with ex vivo expanded haploidentical NK cells as consolidation therapy for children/young adults with intermediate risk AML.
Read the detailed description
Immunotherapy with NK cells may improve the treatment results in AML. For better efficiency high cell doses or several infusions of NK cells are required. For this purpose, donor NK cells are expanded in the presence of feeder K562-mbIL21-41BBL cell line. The cycle of immunotherapy includes chemotherapy (cyclophosphamide, fludarabine) followed by two doses of NK cells infusion.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Expanded haploidentical NK cells in people with Acute Myeloid Leukemia, run by Belarusian Research Center for Pediatric Oncology, Hematology and Immunology at 1 site in Belarus.
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 9 inclusion and 7 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: status not confirmed, as of the sponsor's last update on 28 Aug 2024. 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 Belarus. 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.
What does this combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Tatsiana Shman, PhD (+375296341853, shman@oncology.by), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Relapse-free survival (RFS) (time frame: 2 years). 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 28 Aug 2024.
