Polycythemia Vera
Conditions
Brief summary
The trial will be a phase III, randomised-controlled, multi-centre, international, open-label trial consisting of ruxolitinib versus best available therapy, where best available therapy is a choice of interferon alpha, any formulation permitted (IFN) or hydroxycarbamide (HC), and which will be elected by the Investigator prior to randomisation.
Detailed description
The trial will be a phase III, randomised-controlled, multi-centre, international, open-label trial consisting of ruxolitinib versus best available therapy, where best available therapy is a choice of interferon alpha, any formulation permitted (IFN) or hydroxycarbamide (HC), and which will be elected by the Investigator prior to randomisation. There will be no cross-over either between arm A and B or between therapies on Arm B HC and IFN will be provided as best available therapy, IFN can include standard of pegylated-interferon at Investigators discretion.
Interventions
10mg of ruxolitinib twice daily (bd)
Via standard hospital mechanisms
Any formulation, via standard hospital mechanisms
