Is this trial a fit for you?

Likely a good fit

Ideal candidates include adults aged 18 and older with a confirmed diagnosis of primary or secondary myelofibrosis.

Probably not a fit

Patients with early or prefibrotic primary myelofibrosis or those currently participating in interventional clinical trials may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This multicenter observational study aims to enroll consecutive patients diagnosed with myelofibrosis according to the 2016 or 2022 WHO criteria from various European hematological centers. The study will collect data from both retrospective and prospective patient visits, with yearly follow-ups scheduled until the end of data collection in 2028. The goal is to describe the clinical epidemiology of myelofibrosis, a rare bone marrow disorder with significant symptom burden and poor prognosis, and to refine diagnostic criteria and treatment recommendations based on evolving knowledge in the field.

Why it matters

Potential benefit: If successful, this study could enhance understanding of myelofibrosis and improve patient management and treatment outcomes.

How similar studies have gone: Previous studies, such as the ERNEST observational study, have successfully enrolled large patient cohorts and confirmed prognostic models in myelofibrosis.
