A Phase 2 interventional study of Consolidation #4(without daunorubicin) and Consolidation #4(with daunorubicin) in Leukemia, Lymphoid, sponsored by Yonsei University. Recruiting at 10 sites in South Korea. Open to participants aged Up to 2 Years. Per ClinicalTrials.gov, last updated 2026-07-29.
Sponsored by Yonsei University · Phase 2, Interventional, and Treatment
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.
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.

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