Study summary

This project aims to investigate the therapeutic and repair effects of cord blood mononuclear cells (MNCs) on bone marrow failure after chemotherapy in children with malignant diseases. It is planned to collect 20 malignant children with bone marrow failure after chemotherapy and randomly divide them into two groups. The umbilical cord blood mononuclear cells were injected, ≥1×10\^8 per infusion, once a week, and the recovery time of peripheral blood leukocytes, neutrophils, platelets and hemoglobin was observed. According to the recovery of myelosuppression, stop when the peripheral blood reaches leukocytes>1×10\^9/L, neutrophils>0.5×10\^9/L, platelets>25×10\^9/L, and hemoglobin>60g/L at the same time. Use, share 1-4 times.

Statistical software was used to compare the changes of peripheral blood leukocytes, neutrophils, platelets and hemoglobin before the start of the test (0d) and 1d, 3d, 5d, 7d, 10d, and 14d after the start of the test, as well as the severity of concurrent infections and antibiotic use Time, number of infusions of blood products.

Read the detailed description

The standard of bone marrow failure after chemotherapy is based on theWorld Health Organization(WHO) grade IV myelosuppression standard, that is, peripheral blood white blood cells (WBC) \< 1 × 10\^9/L, neutrophils (N) \<0.5 × 10\^9/L, platelets (PLT) \<25×10\^9/L, hemoglobin (Hb) \<60g/L, for more than 2 weeks. It is planned to collect 20 malignant children with bone marrow failure after chemotherapy and randomly divide them into two groups. The umbilical cord blood mononuclear cells were injected, ≥1×10\^8 per infusion, once a week, and the recovery time of peripheral blood leukocytes, neutrophils, platelets and hemoglobin was observed. According to the recovery of myelosuppression, when the peripheral blood reaches WBC>1×10\^9/L, N>0.5×10\^9/L, PLT>25×10\^9/L, and Hb>60g/L at the same time, it should be discontinued and used together. 1-4 times.

Safety evaluation: Children under treatment who meet any one or more of the following, the study will be terminated or withdrawn: (1) Within 6 hours after the treatment with venous cord blood mononuclear cells, the clinical symptoms that cannot be explained by known causes are significantly aggravated or In case of deterioration, the trial should be terminated, and appropriate treatment should be carried out. The withdrawn cases should be included in the clinical efficacy evaluation, and the count is invalid; (2) During the treatment and within 6 hours after the treatment, the following conditions that cannot be explained by the known causes occur: severe hypotension, contraction Blood pressure drops ≥20mmHg or systolic blood pressure \<70mmHg; severe hypertension, systolic blood pressure rises ≥20mmHg or systolic blood pressure>140mmHg, the test should be terminated; (3) During treatment and within 6 hours after treatment, chills, Patients with fever (body temperature ≥39°C), rash, headache, low back pain and other symptoms should stop the test; (4) If serious adverse events occur, the test should be stopped.

Efficacy evaluation: compare the changes of peripheral blood leukocytes, neutrophils, platelets and hemoglobin before the start of the test (0d) and 1d, 3d, 5d, 7d, 10d, and 14d after the start of the test, as well as the severity of concurrent infection and antibiotic use Time, number of infusions of blood products.

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

  1. Age ≤ 17 years old;
  2. Treated in pediatric hematology department from September 2021 to September 2024, patients with bone marrow failure after transplantation;
  3. (ECOG) score ≤ 2;
  4. Sign the form (\< 10 years old, signed by the guardian; ≥ 10 The children and their guardians signed the informed consent form before the selection.

Exclusion criteria

Exclusion Criteria:

  1. Those who have received thoracic radiotherapy in the past;
  2. Those who do not meet the above inclusion criteria.
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.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

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.

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 28, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
