Clinical Trial Summary

This is a Phase 2 study with an open-label dose escalation phase followed by a blinded withdrawal phase and an open label extension. The study is designed to monitor the PTG-300 safety profile and to obtain preliminary evidence of efficacy of PTG-300 for the treatment of phlebotomy-requiring polycythemia vera.


Clinical Trial Description

Phase 2 study in approximately sixty subjects previously diagnosed with Polycythemia Vera who require phlebotomy on a routine basis. There is a 28 week dose finding phase to identify a dose that maintains hematocrit <45%. Subjects who successfully complete the dose finding phase will be entered into a 12 week randomized withdrawal phase to confirm the response. Subsequently patients will enter into an up to 3 year open label extension to investigate long term safety. ;
