Study summary

This study aims at evaluating the safety and the tolerance of the micro-transplantation in elderly patients with acute myeloid leukemia who are ineligible to conventional allogeneic transplantation.

Read the detailed description

Acute Myeloid Leukemia (AML) is an aggressive hematological malignancy with a median age at diagnosis of 65 years. Outcomes of AML in elderly population remain unsatisfactory with low rates of complete remission, poor disease-free and overall survival. Therapeutic management of older patients with AML deals with patient-related features (i.e. comorbid conditions and performance status) as well as disease-related prognostic factors (i.e. cytogenetics and molecular genetics). Even if allogeneic hematopoietic-cell transplantation provides the strongest antineoplasic effect, this treatment option remains limited for older patients owing to toxicities, the development of significant graft-versus-host disease (GVHD) and logistics of donor availability. More recently, micro-transplantation has emerged as an alternative strategy based on the infusion of mobilized HLA-mismatched related donor cells after induction chemotherapy, thus exerting a graft-versus-leukemia effect without substantial donor engraftment and GVHD. Therefore, there is much of interest in investigating the efficacy and the safety of this method for older patients with AML who are not candidates for allogeneic stem cell transplantation.

  • Patient, ≥ 60 years-old - \< 75 years-old, with established diagnosis of de novo or secondary AML with intermediate-risk or adverse-risk cytogenetic profile, or with established myelodysplasic syndromes (RAEB), in confirmed complete remission following anti-leukemic induction therapy (\<5% blasts)

  • Normal karyotype with a favorable molecular profile: NPM1+ and FLT3-; NPM1+, FLT3- and double mutation CEBPα or chronic myeloid leukemia in blastic phase

Terms in these criteria, in plain language(4)

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.

Informed consent

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.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

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.

Ran from Jan 2019 to primary completion in Jan 2024, 60 months.

Since we started tracking on Sep 25, 2026, the dates moved once, on Oct 13, 2026: primary completion Dec 2025 → Jan 2024 and completion Dec 2027 → Jul 2024.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
