About this study

Official title: National Prospective Cohort for Monitoring Children With Severe Autoimmune Cytopenia

This study aims to study prospectively the clinical and paraclinical evolution and prognostic factors of autoimmune haemolytic anemias, Evans syndromes and chronic immunological thrombocytopenic purpura of children in France.

Read the detailed description

These autoimmune haematological diseases are rare diseases affecting the child, often very young, and serious and potentially life-threatening. International literature data are scarce, and include individual cases or small series.

They do not allow to determine an optimal therapeutic strategy in case of escape from the first-line treatments. Existing treatments (long-term corticosteroid therapy, immunoglobulins, splenectomy, immunosuppressants, chemotherapies, and more recently anti-CD20 antibodies) are inconsistently effective, and often associated with serious side effects.

The seriousness of these diseases, the therapeutic difficulties, and the absence of a targeted research project in France, led to the implementation of this study.

This study aims to study prospectively the clinical and paraclinical evolution and prognostic factors of autoimmune haemolytic anemias, Evans syndromes and chronic immunological thrombocytopenic purpura of children in France.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Complete sustainable remission (yes/no) for children with autoimmune haemolytic anemias

    Absence of clinical signs of anemia (grade 0) And Hemoglobin > 11 g / dl And reticulocytes <120,000 / mm3 And haptoglobin> 10 mg / dl And bilirubin <10 mg / l or 17 μmol / l And no specific treatment for at least 12 months

    Measured: At the screening

  2. complete remission (yes/no) for children with autoimmune haemolytic anemias

    Absence of clinical signs of anemia (grade 0) And Hemoglobin> 11 g / dl And reticulocytes <120,000 / mm3 Regardless of the level of haptoglobin or bilirubin And specific treatment in progress or interrupted for less than 12 months

    Measured: At the screening

  3. partial remission (yes/no) for children with autoimmune haemolytic anemias

    Clinical Signs of Anemia (Grade 1 or 2) Or Hemoglobin from 7 to 11 g / dl Or reticulocytes> 120,000 / mm3 Regardless of the level of haptoglobin or bilirubin

    Measured: At the screening

  4. no response (yes/no) for children with autoimmune haemolytic anemias

    Clinical Signs of Severe Anemia (Grade 3 or More) Or Hemoglobin <7 g / dl

    Measured: At the screening

  5. deceased patient (yes/no) for children with autoimmune haemolytic anemias

    Death yes/no

    Measured: At the screening

  6. Complete sustainable remission (yes/no) for children with chronic immunologic thrombocytopenic purpura

    Absence of clinical signs of haemorrhage (grade 0) And platelets> 100,000 / mm3 And no specific treatment for at least 12 months

    Measured: At the screening

  7. complete remission (yes/no) for children with chronic immunologic thrombocytopenic purpura

    Absence of clinical signs of haemorrhage (grade 0) And platelets> 100,000 / mm3 And specific treatment in progress or interrupted for less than 12 months

    Measured: At the screening

  8. partial remission (yes/no) for children with chronic immunologic thrombocytopenic purpura

    Clinical Signs of Hemorrhage (Grade 1 or 2) Or platelets between 30,000 and 100,000 / mm3

    Measured: At the screening

  9. no response (yes/no) for children with chronic immunologic thrombocytopenic purpura

    Clinical Signs of Severe Hemorrhage (Grade 3 or Greater) Or Platelets <30,000 / mm3

    Measured: At the screening

  10. deceased patient (yes/no) for children with chronic immunologic thrombocytopenic purpura

    Death yes/no

    Measured: At the screening

Questions about this trial

What is this clinical trial studying?

An observational study of Cytopenia and Autoimmune Haemolytic Anaemia, run by University Hospital, Bordeaux.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Jun 2026. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Complete sustainable remission (yes/no) for children with autoimmune haemolytic anemias (time frame: At the screening). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04070612, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Jun 2026; AzTrials last refreshed its copy on 8 Nov 2026.
