Myelofibrosis is associated with severe, frequent symptom burden1

Progressive, relentless symptoms impair QoL and increase disability2-4

  • MF-related symptoms compromise social functioning, physical activity, independence, and QoL1,5
  • Constitutional MF symptoms negatively impact QoL and are associated with poor prognosis for survival4,6
  • Fatigue is extremely common and is similar to or worse than that suffered by patients undergoing chemotherapy for haematologic malignancies7

High incidence and wide variety of symptoms of MF1

Splenomegaly and other symptoms have high incidence in patients with Myelofibrosis - JAKAVI

Adapted from: Scherber R et al. Blood. 2011;118:401-408.1

QoL scores for MF patients were worse than those for all cancer patients combined8

Mean baseline EORTC QLQ-C30 HRQoL scores for patients with MF (COMFORT-II) compared with scores for all cancer patients by age group8

Prognosis for MF patients were worse than those for all cancer patients combined - JAKAVI

Adapted from: Kiladjian J et al. Poster presented at ASCO Annual Meeting, 2012.8

MF-related symptoms are progressive and may worsen even with conventional therapies9,10

Symptom scores worsened with placebo9

Symptoms of Myelofibrosis are progressive and may worsen with conventional therapies - JAKAVI

Adapted from: Verstovsek S et al. N Engl J Med. 2012;366:799-807.9

Symptoms measured with the use of a modified Myelofibrosis Symptom Assessment Form (MFSAF), version 2.0.

Symptoms scores worsened from baseline with conventional therapies throughout 48-week study period10

Myelofibrosis-related symptoms including appetite loss, insomnia, dyspnea, pain, and fatigue worsened with conventional therapies during a 48-week study period - JAKAVI

Adapted from: Harrison C et al. N Engl J Med. 2012;366:787-798.10

Symptoms measured by European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire core model.
