Clinical summary

Summary

Myelofibrosis patients with high molecular risk mutations have an intrinsically aggressive disease with increased risk of leukemic transformation and reduced overall survival. As there are no therapies currently established in the subset of high molecular risk patients with early myelofibrosis, the study aims to evaluate ruxolitinib in this patient population. Patients will be randomized into each arm of the trial. Participants, care takers and investigators will not know which arm of the study each participant is in.

Conditions

This trial is treating people with Myelofibrosis

  • Patients with non-palpable spleen or spleen palpable ≤ 5 cm from the left costal margin to the point of greatest splenic protrusion
  • Patients with MF-7 score of ≤ 15, with each individual symptom score of ≤ 3

Exclusion
