Clonal Architecture of ASXL1-mutated Myelofibrosis

Study Purpose

Prospective study to decipher the clonal architecture of ASXL1-mutated primary and secondary myelofibrosis and its impact on prognosis

Recruitment Criteria

Accepts Healthy Volunteers Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms	No
Study Type An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies.	Interventional
Eligible Ages	18 Years and Over
Gender	All

More Inclusion & Exclusion Criteria

Inclusion Criteria:

- Adults (age ≥18 years), - Affiliated to the national social security system, - ASXL1 mutated primary or secondary myelofibrosis, - Signed the consent to participate in the study, - Included, or consenting to be included, in the national clinical-biological database of France Intergroupe Syndrome Myéloprolifératifs (FIM).

Exclusion Criteria:

- Patient with another active hematological disease or cancer at the time of diagnosis, - Person subject to legal protection scheme or incapable of giving consent.

Trial Details

Trial ID: This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.	NCT05710211
Phase Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.	N/A

Additional Details

The clonal architecture of myelofibrosis patients is still little described. Inconsistent results in terms of the prognostic value of some mutations are observed in the literature, in particular concerning ASXL1 mutations. We assume that a better understanding of the clonal architecture of ASXL1-mutated myelofibrosis could help refining the prognostic impact of ASXL1 mutations. This study aims to evaluate a multicenter cohort of 50 patients. Blood of patients will be collected within 18 months of diagnosis. After 4 years of follow-up of the patient as part of his usual care, data on survival and leukemic transformation will be collected.
