Brief summary

This is a Phase IV, multicenter, non-interventional, non-randomized, prospective, observational study in an adult population (patients \>18 years old) of men and women who have been diagnosed with clinically overt PV and are being followed in either community or academic medical centers in the United States who will be enrolled over a 12-month period and observed for 36 months from the date the last patient is enrolled.

Design outcomes

Primary

MeasureTime frameDescription
Description of patterns of the disease Polycythemia Vera (PV), and associations of such patterns with patients' exposures or treatmentsEvery 3 months for approximately 36 months
Incidence (frequency) of disease progressionEvery 3 months for approximately 36 months
Incidence (frequency) of healthcare resources utilizationEvery 3 months for approximately 36 monthsHealthcare resources were defined as a. Medical visits (including Office visits, ER visits, and hospitalizations), b. phlebotomy (PHL) procedures and c. prescriptions (including PV-related prescriptions, PV-related over-the-counter (OTC) medications, and prescription medications for co-morbid conditions).
Incidence (frequency) of complications due to PVEvery 3 months for approximately 36 months
Incidence (frequency) and description of PV-related symptomsEvery 3 months for approximately 36 months

Secondary

MeasureTime frameDescription
Incidence (frequency) of adverse events (for those patients on active therapies, including PHL)Baseline through end of study. Approximately 36 months
Burden of phlebotomy (PHL)Every 3 months for approximately 36 monthsA patients self-reported assessment of burden including pain at site, difficulty and inconvenience of scheduling and cost factors.
Patient-reported outcomes as assessed by Myeloproliferative Neoplasm Symptom Assessment Form Total Symptom Score (MPN-SAF TSS) for assessment of the severity of symptomsEvery 3 months for approximately 36 monthsThe MPN-SAF TSS is a validated 10-item instrument that efficiently assesses the prevalence and severity of PV symptoms in both clinical practice and trial settings. Higher scores indicate more severe symptoms and greater inactivity with a possible total score range of 0-100.
Work Productivity and Activity Impairment Questionnaire - Specific Health Problem (WPAI-SHP) score for assessment of work productivity and activity impairmentEvery 3 months for approximately 36 monthsWPAI-SHP is a validated 6-item instrument that measures the effect of overall health and specific symptoms on productivity at work and outside of it. All outcomes are presented as a proportion, with 0% representing minimal/no impairment and 100% representing maximal impairment or productivity loss.
European Organization for Research and Treatment of Cancer Core Quality of Life Questionnaire (EORTC QLQ-C30) for Health Related Quality of Life (HRQoL)Every 3 months for approximately 36 months
Caregiver burdenEvery 3 months for approximately 36 monthsThe amount of health care received by a paid healthcare worker or by an unpaid caregiver
