چکیده

abstract


Polycythemia vera (PV) is characterized by erythropoiesis and JAK2-activating mutations, with increased risks of morbidity and mortality. Most patients with PV are iron deficient, and treatment often includes hematocrit control with phlebotomy, which may exacerbate iron deficiency-associated complications. The phase 3 RESPONSE trial evaluated the JAK1/JAK2 inhibitor ruxolitinib (n = 110) versus best available therapy (BAT; n = 112) in patients with PV who were hydroxyurea-resistant/intolerant. Ruxolitinib was superior to BAT for hematocrit control, reduction in splenomegaly, and blood count normalization. This exploratory analysis, the first to evaluate iron status in a prospective study of patients with PV, investigated ruxolitinib effects on 7 serum iron markers and iron deficiency-related patient-reported outcomes (PRO). Among patients with evidence of baseline iron deficiency, ruxolitinib was associated with normalization of iron marker levels, compared with lesser improvement with BAT. Iron levels remained stable in ruxolitinib patients with normal iron levels at baseline. Regardless of baseline iron status, treatment with ruxolitinib was associated with improvements in concentration problems, cognitive function, dizziness, fatigue, headaches, and inactivity, although improvements were generally greater among patients with baseline iron deficiency. The improvements in iron deficiency markers and PROs observed with ruxolitinib are suggestive of clinical benefits that warrant further exploration.

Conclusion


In conclusion, ruxolitinib treatment of patients with PV was associated with rapid and sustained improvements in iron indices, compared with lesser improvements with best available therapy. Regardless of iron indices at baseline, ruxolitinib treatment was associated with improvements in patient-reported outcomes on the MPN-SAF and EORTC QLQ-C30. The rapid improvements in markers of iron deficiency with ruxolitinib treatment observed in this analysis are suggestive of a clinical effect that warrants further exploration.
