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.

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.
