Study Details

Study Description

Brief Summary

This trial is a translational, open-label, multi-site, retrospective and prospective cohort study of 250 patients aiming to characterize predictive parameters of clonal evolution in a population of subjects carrying the germline GATA2 mutation.

The study will be conducted on a population of subjects either with previous germline GATA2 mutation identified or newly identified for germline GATA2 mutation in the context of routine care.

Prospective cohort:

150 subjects will be included in this prospective cohort study:

  • Alive subjects previously identified with a germline GATA2 mutation through the already existing "Neutropenia database";

  • Subject identified in the investigating centers in the context of a newly identified germline GATA2 mutation.

For each included patient, biological samples (blood and bone marrow samples) will be collected at baseline visit and then during 5 years, according to the samples taken in the standard practice. No additional sampling will be performed for the study.

Retrospective cohort:

Subjects (100 cases in total) previously identified with germline GATA2 mutation through the already existing "Neutropenia database" and with the following features may enter the retrospective cohort:

  • Deceased patients,

  • Lost to follow-up patients. Clinical follow-up data will be obtained from this database and/or patient's medical report.

For each retrospective case, archived blood and bone marrow samples (collected in a sanitary setting) will be sent to sponsor's centralized unit for analysis.

Arms and Interventions

Arm Intervention/Treatment
Other: Subject with a germline GATA2 mutation (Prospective cohort)

Other: Biological samples (blood and bone marrow samples).
For each included patient, biological samples (blood and bone marrow samples) will be collected at baseline visit and then during 5 years, according to the samples taken in the standard practice. No additional sampling will be performed for the study.

Outcome Measures

Primary Outcome Measures

  1. Time to appearance of spectrum 2, defined as the delay between date of birth and appearance of an event classified as spectrum 2. [5 years for each patient]

    Spectrum 2 corresponds to MDS (Myelodysplastic Syndromes) with excess blasts, AML (Acute myeloid Leukemia) or CMML (Chronic myelomonocytic leukemia).

Secondary Outcome Measures

  1. Time to appearance of spectrum 1, defined as the delay between date of birth and appearance of spectrum 1. [5 years for each patient]

    Spectrum 1 corresponds to hypoplastic marrow and/or low-grade MDS (without excess blasts).

  2. Time to appearance of first hematological event defined by the delay between date of birth and appearance of first hematological. [5 years for each patient]

  3. Disease Free Survival (DFS) defined as the time from Leukemia diagnosis until first /relapse or death from any cause. [5 years for each patient]
