Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages Up to 18 years
  • All sexes
  • No healthy volunteers
  • Child, Adult

Study population: Children or adolescents who have received one or more treatments of interest for a Chronic Immune-Thrombocytopenic Purpura, Autoimmune Hemolytic Anemia , or EVANS syndrome, in one of the 30 centers of the CEREVANCE network, will be identified and selected by the team CEREVANCE, in the OBS'CEREVANCE computer database created since 2004. The first second-line treatment they received will be analyzed.

Who may be able to join

  • Patient initiating a first second-line immunomodulatory treatment (azathioprine, ciclosporine, eltrombopag, hydroxychloroquine, mycophénolate mofétil, rituximab, romiplostim), registered in the OBS'CEREVANCE database, presenting a Chronic Immune-Thrombocytopenic Purpura, Autoimmune Hemolytic Anemia or simultaneous EVANS syndrome.

Who cannot join

  • Patient under immunosuppressant for another immunological pathology at the initiation of the first second line treatment,
  • Patient treated with 2 second-line treatments on the same day,
  • Oral refusal of participation of the patient or his legal representatives, after reading the information note specific for the study.

About this study

Official title: National Study Backed by a Rare Disease Cohort the Benefit / Risk Balance of Immunomodulatory Treatments Prescribed in the Child and Adolescent for Autoimmune Cytopenia.

In France, a national prospective cohort for monitoring children and adolescents with autoimmune cytopenia OBS'CEREVANCE is in place since 2004. It is coordinated in Bordeaux by the Center's team. Reference Rare Diseases CEREVANCE. It has been validated by the French Data Protection Authority in 2009 (information note and written consent). It had mid 2013 more of 900 patients, and the data collected make it possible to study intentionally to treat the therapeutic management of patients with Chronic Immune-Thrombocytopenic Purpura, from Autoimmune Hemolytic Anemia, or from EVANS syndrome.

This study evaluates efficacy and tolerance at 6 months of treatment immunomodulators prescribed in France in real conditions of use, in children and adolescents under the age of 18, for a Chronic Immune-Thrombocytopenic Purpura, an Autoimmune Hemolytic Anemia or a simultaneous EVANS syndrome.

Read the detailed description

Chronic immunological thrombocytopenic purpura and anemia hemolytic autoimmune are rare autoimmune hematologic diseases, primary or secondary, affecting the child often very young, sometimes associated simultaneously or sequentially (Evans syndrome). They can be life-threatening, they in 20 to 50% of cases of prolonged dependence on immunosuppressants. The incidence of Immune-Thrombocytopenic Purpura is 2 to 5 / 100,000 inhabitants of under 18, the Autoimmune Hemolytic Anemia 5 to 10 times lower.

For the pediatric population, the experience reported in the literature is limited to individual cases or small series often retrospective and not comparative. It does not allow to have in 2013 a reasoning based on on evidence to define the second-line therapeutic strategy, in especially for Autoimmune Hemolytic Anemia where the therapeutic data are almost nonexistent. Splenectomy remains to this day the reference treatment of the Chronic Immune-Thrombocytopenic Purpura of the adult. In children, the therapeutic goal is to avoid it or to prevent it delay it. After failure of first-line treatments (immunoglobulins or corticosteroids) used for treatment of relapses or continuously, the main immunomodulatory treatments used in second line are azathioprine, ciclosporin, hydroxychloroquine, rituximab, mycophenolate mofetil, romiplostim, eltrombopag.

The benefit / risk balance of these 7 immunomodulatory treatments prescribed to the child for autoimmune cytopenia is presumed to be favorable based on the very limited data from the pediatric literature and the experience of most adults do not benefit from a specific marketing authorization.

What is being measured

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

  1. Haemorrhagic sign - Grade ≥ 3 (Buchanan score) Presence of a haemorrhagic sign ≥grade 3

    Presence of a haemorrhagic sign ≥ grade 3 = moderate bleeding (Buchanan score : from 0 to 5)

    Measured: At 6 months

  2. Thrombocytopenia Presence of thrombocytopenia <30 G / L

    Presence of thrombocytopenia <30 G / L

    Measured: At 6 months

  3. Need of a transfusion ?

    Performing a transfusion : yes or no ?

    Measured: At 6 months

  4. Immunoglobulin IV Immunoglobulin IV

    Immunoglobulin IV push

    Measured: At 6 months

  5. Corticoids push

    Corticoid push (no reduction of their number during treatment follow-up versus non-treatment period)

    Measured: At 6 months

  6. Need a splenectomy ?

    Performing a splenectomy : yes or no ?

    Measured: At 6 months

  7. Clinical signs of anemia

    Presence of clinical signs of anemia ≥ grade 2 = Subject bedridden less than 50% of the day (WHO score : from 0 to 4)

    Measured: At 6 months

  8. Anemia

    Presence of anemia <7g / dl

    Presence of anemia <7g / dl

    Measured: At 6 months

  9. Introduction of a new immunomodulatory treatment

    Introduction of a new immunomodulatory treatment : yes or no ?

    Measured: At 6 months

  10. Stop treatment or not ?

    Stop treatment because of failure, intolerance or non-compliance

    Measured: At 6 months

Individual data sharing
No: Through this program, a coordinated and centralized analysis of reliable pharmacovigilance data will be transmitted in real time to the National Agency for Medicines. It will enable National Agency for Medicines to ensure the safe use of these treatments for the pediatric population, vulnerable, and optimize monitoring in the short and long term identified or potential risks of these treatments on a developing immune system. It will also ensure the monitoring of off-label or Temporary Therapeutic Protocol / Temporary recommendation for use prescriptions and to argue recommendations for good use. For treatments whose benefit will be confirmed, these results will be useful to the medical community to define the best second-line therapeutic strategy.

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?

Haemorrhagic sign - Grade ≥ 3 (Buchanan score) Presence of a haemorrhagic sign ≥grade 3 (time frame: At 6 months). 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?
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?
