Currently Enrolling Trials

A Phase 3b, randomized, open-label, parallel-group, multicenter study to evaluate the efficacy and safety of two dosing regimens of ropeginterferon alfa-2b-njft. NCT05481151
Completed Trials


A Phase 1/2, prospective, multicenter, open-label, dose-escalation trial to determine the safety, efficacy, and tolerability of ropeginterferon alfa-2b-njft in patients with PV, and define the maximum tolerated dose.


A Phase 3b, open-label extension trial in patients who completed PROUD-PV to assess the long-term efficacy of ropeginterferon alfa-2b-njft or standard first-line treatment (HU or other best available treatment*) in terms of disease response rate and changes in disease burden.

*Includes peginterferon alfa-2a, acetylsalicylic acid, anagrelide, IFN alfa, ruxolitinib, IFN alfa-2a, both ruxolitinib and IFN alfa-2a, ropeginterferon alfa-2b-njft, or both ropeginterferon alfa-2b-njft and IFN alfa-2a.


A Phase 3, randomized clinical trial conducted across 48 clinics in Europe to assess the noninferiority of ropeginterferon alfa-2b-njft versus hydroxyurea (HU) regarding disease response in the treatment of PV.
