Study summary

This prospective non-randomized multicenter trial created based on protocol ML DS 2006 and aimed at standardization of current therapy approaches and creating a national network for diagnostic, treatment and monitoring of children (0-18 years) with AML and Down syndrome in Russia. Based on the results the investigators expect to increase long-term overall and event-free survival in children with AML and DS and reduce the immediate and remote toxicity of chemotherapy by reducing the dose load of chemotherapeutic drugs.

The study protocol therapy for all patients includes four chemotherapy blocks:

Course 1 AIE (cytarabine/idarubicin/etoposide) Course 2 AI (cytarabine/idarubicin) Course 3 HAD (high -dose cytarabine (1g)/daunorubicin) Course 4 HA (high-dose cytarabine) Safety to be monitored based on CTCAE v5.0

This prospective non-randomized multicenter trial created based on protocol ML DS 2006 and aimed at standardization of current therapy approaches and creating a national network for diagnostic, treatment and monitoring of children (0-18 years) with AML and Down syndrome in Russia. Based on the results the investigators expect to increase long-term overall and event-free survival in children with AML and DS and reduce the immediate and remote toxicity of chemotherapy by reducing the dose load of chemotherapeutic drugs.

Patients to be included: Age 0-18 years

  • Diagnosis of AML, MDS and presence of Down syndrome (constitutional trisomy 21 and mutation in the GATA1 gene)
  • Signed informed consent

Patients not be included:

  • Children with Down syndrome and acute lymphoblastic leukemia (ALL)
  • Severe comorbidities with contraindications to the treatment according to the protocol
  • Pre-treatment >14 days with intensive induction therapy
  • Refusal of all therapy or important elements of therapy

NB: Patients with Transient Abnormal Myelopoiesis (TAM) are eligible for enrollment but will be included in the analysis as a separate group.

Patients with M7 AML, trisomy 21 in the tumor clone (without the Down syndrome phenotype) and mutation in the GATA1 gene should be discussed individually with the protocol group to determine the treatment strategy, as patients with M7 AML and trisomy 21 in tumor clone (without the Down syndrome phenotype) are not included in current version of pediatric AML clinical recommendations.

If a patient meets the inclusion criteria, but cannot/should not receive treatment according to the protocol, he/she can be enrolled in the study as a patient under observation. The results of therapy of patients under observation will not be taken into account in the assessment of treatment efficacy.

The study protocol therapy for all patients includes four chemotherapy blocks:

Course 1 AIE (cytarabine/idarubicin/etoposide) Course 2 AI (cytarabine/idarubicin) Course 3 HAD (high-dose cytarabine (1g)/daunorubicin) Course 4 HA (high-dose cytarabine)/ Efficacy parameters include Response rate; event-free survival (EFS); relapse-free survival (RFS); overall survival (OS); treatment-related mortality, myelogram, MRD Safety to be monitored based on CTCAE v5.0 The AML-DS-2025 protocol does not include a maintenance therapy course in order to reduce toxicity and improve quality of life.

Terms in these criteria, in plain language(2)

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.

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.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jul 2025 (actual). Primary completion is estimated for Jul 2030, 60 months after the start.

Of 78 non-industry phase 3 interventional studies under Leukemia, Myeloid, Acute, half reached primary completion within 87 months of starting (the median), counting those still running; a quarter within 66 and three quarters within 111. This study's planned 60 months is below that.

Counting every sponsor, half of 120 studies reached it within 74 months; a quarter within 39 and three quarters within 99.

How these figures are worked out, and which studies are left out of them.

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.
No changes since tracking began. The registry record was last updated on Nov 20, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
