Study summary

This clinical trial is an open-label, multicenter, prospective phase 2 clinical trial targeting pediatric leukemia patients of infant age. The goal is to improve survival rates by varying the presence or absence of chemotherapy and hematopoietic stem cell transplantation based on genetic characteristics at the time of diagnosis and minimal residual disease (MRD) values measured by various methods after treatment.

In addition, by clearly defining the patient group that requires hematopoietic stem cell transplantation, it is expected that the role of hematopoietic stem cell transplantation in infantile leukemia, for which there have been various guidelines for hematopoietic stem cell transplantation, can be confirmed. Additionally, due to the characteristics of infants, this study aim to identify long-term sequelae or prognosis related to treatment by prospectively collecting side effect data related to treatment during and after treatment.

Read the detailed description

Infant leukemia patients are classified into low/intermediate/high risk groups and hematopoietic stem cell transplantation is performed after chemotherapy or chemotherapy as shown in the schema below.

  • Low risk group : Induction chemotherapy-Low Risk Consolidation chemotherapy 1\~4 - Maintenance chemotherapy
  • Intermediate risk group : Induction chemotherapy-High Risk Consolidation chemotherapy 1\~4 - Maintenance chemotherapy
  • High risk group : Induction chemotherapy-High Risk Consolidation chemotherapy 1\~4 - hematopoietic stem cell transplantation

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • The age of diagnosis is less than 1 year old
  • The disgnosisi of ALL or ALAL(lymphoid predominant)
  • of the parents(guardians) before participation in this study

Exclusion criteria

Exclusion Criteria:

  • Burkitt leukemia/lymphoma or mature B-cell leukemia
  • Down syndrome, Bloom syndrome, ataxia-telangiectasia, Fanconi anemia, Kostmann syndrome, Shwachman syndrome or other bone marrow failure syndrome, hematopoietic stem cell transplantation
  • infant leukemia
  • Participants with to medication
  • Administered systemic therapy within 4 weeks prior to this study (However, steroid administration is allowable in oncologic emergencies only after the subject's disease diagnosis and risk group classification are completed.)
  • Participants in other interventional studies other than this protocol
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.

Relapsed and refractory

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

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.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

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 Jul 29, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
