About this study
Official title: Phase II, Multicenter, Open Label, Prospective to Evaluate Efficacy and Tolerance of a Chemoimmunotherapy With HyperCVAD or Vincristine/Dexamethasone Plus the Anti-CD22 Monovlonal Antobody Epratuzumab for the Treatment of Adult Relapsed/Refractory CD22+ B-Acute Lymphoblastic Leukaemia Patients : CHEPRALL Study, a GRAALL Study.
Patients with relapsed/refractory adult acute lymphoblastic leukemia (ALL)have a very dismal prognosis. In this case, allogeneic transplantation is the only curative treatment when patient have obtained a second complete remission (CR. In France, in patients younger than 60 years old,the HyperCVAD regimen used by the MDAnderson in Houston is generally applied. In older patients (>=60 years)or young patients <= 60 years no eligible for intense chemotherapy, a combination of vincristine + Dexamethasone is generally chosen in order to avoid too much toxicity but the result is worse in term of CR.
More than 90% of ALL with a B phenotype (2/3 of cases in adults)express the surface antigen CD22 on leukemic blasts which thus represents an interesting target for therapy. Epratuzumab is a humanized anti-CD22 antibody produced by Immunomedics, Inc, Morris Plain (New Jersey, USA). Epratuzumab has already shown efficacy in lymphoma patients. Only one study, including 15 children, has been published so far reporting the efficacy and the toxicity of Epratuzumab in the setting of ALL in monotherapy, one can observe 8 stable disease, 3 progressions and 4 partial responses. When combining chemotherapy and Epratuzumab, 9CR were observed with acceptable toxicity. Tolerance was acceptable.
The French GRAALL group proposes to test an age-adapted combination of chemotherapy + Epratuzumab, in refractory/relapses CD22+ B ALL patients in order to improve their prognosis, in term of CR, survival and of number of patients eligible for allograft.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Epratuzumab in people with B ALL and CD22+ Expression, run by Nantes University Hospital at 11 sites in France.
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 10 inclusion and 11 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 14 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 11 sites in France. Whether a site is taking part right now should be confirmed with that site. See every site.
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.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
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 response rate (CR and CRp). 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 NCT01219816, 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 14 Sep 2026.
