Overview
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.
