NCT02809274

Brief Summary

Iron deficiency is a known feature of PV, occurs because of accelerated erythropoiesis, gastrointestinal blood loss and phlebotomy. Incidence and effect of iron deficiency in these patients is not well characterized. The study will assess the incidence of iron deficiency at diagnosis and during the course of PV, assess effect of iron deficiency on patient symptoms and its correlation with disease features. This is a multicenter, non-interventional, non-randomized, prospective, observational study in an adult population (patients \>18 years old) of patients who have been diagnosed with PV and are being followed in either community or academic medical centers in Israel.

Outcome Measures

Primary Outcomes (1)

  • Incidence of iron deficiency in patients with PV

    2 years

Secondary Outcomes (4)

  • Association between iron deficiency and other clinical features

    2 years

  • Influence of therapy (phlebotomies, hydroxyurea, other therapies) on iron parameters

    2 years

  • Influence of iron parameters on Patient-reported symptoms

    2 years

  • Influence of iron deficiency on arterial and venous thrombosis rate

    2 years

Study Arms (2)

Patients with PV, not newly diagnosed

Patients with clinically overt PV treated with watchful waiting (with or without aspirin), Phlebotomy (PHL), Hydrea or any other treatment. Influence of iron parameters on Patient-reported symptoms will be evaluated by questionnaires Blood serum samples will be taken for iron parameters analysis

Other: questionnaires

Newly diagnosed patients with PV

Patients with clinically overt PV, newly diagnosed, before any treatment and before phlebotomy initiation. Influence of iron parameters on Patient-reported symptoms will be evaluated by questionnaires Blood serum samples will be taken for iron parameters analysis

Other: questionnaires

Interventions

• Influence of iron parameters on Patient-reported symptoms as assessed by Myeloproliferative Neoplasm Symptom Assessment Form Total Symptom Score (MPN-SAF TSS) for assessment of the severity of symptoms, Quality of life evaluation by The European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) and fatigue assessment by PROMIS Fatigue Scale: Short Form

Newly diagnosed patients with PVPatients with PV, not newly diagnosed

  • Willing and able to provide written informed consent
  • Willing and able to complete patient assessment questionnaires either alone or with minimal assistance from a caregiver and/or trained site personnel
  • Under the supervision of a physician for the current care of PV including but not limited to watchful waiting, acetylsalicylic acid (ASA) 81mg or greater, antithrombotic therapy, Phlebotomy (PHL), Hydroxyurea (HU), interferon (recombinant or pegylated), busulfan, anagrelide

You may not qualify if:

  • Diagnosis of myelofibrosis (MF) \[including primary MF, post-PV MF, or post-essential thrombocythemia MF (post-ET MF)\]
  • Diagnosis of secondary Acute Myeloid Leukemia (AML)
  • Diagnosis of Myelodysplastic Syndrome (MDS)
  • Splenectomy
