A Phase 1/2 interventional study of Expanded haploidentical NK cells in Acute Myeloid Leukemia, sponsored by Belarusian Research Center for Pediatric Oncology, Hematology and Immunology. Recruiting at 1 site in Belarus. Open to participants aged 6 Months to 21 Years. Per ClinicalTrials.gov, last updated 2024-08-28.

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.
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.
3,667 studies on the registry are indexed under Leukemia, Myeloid, Acute; 816 are open to participants now.
This study's planned enrollment of 15 is below the median of 40 across 3,005 interventional studies indexed under Leukemia, Myeloid, Acute.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.
A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.
Studies often ask for 60 or 70 and above. Your doctor gives the score.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Allogeneic and autologous transplant
Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.

Karnofsky performance status (KPS)
