Ropeginterferon Alfa-2b Shows Superior Efficacy Over Anagrelide in Phase III Essential Thrombocythemia Trial
- Ropeginterferon alfa-2b achieved a 42.9% sustained response rate compared to 6.0% with anagrelide in patients with essential thrombocythemia resistant or intolerant to hydroxyurea.
- The drug demonstrated superior molecular responses with 27.8% partial and 2.8% complete molecular responses, while anagrelide showed no molecular responses.
- Ropeginterferon alfa-2b significantly reduced thrombotic events to 1.1% versus 8.8% with anagrelide and showed better safety profile with fewer treatment discontinuations.
- The SURPASS-ET trial results support ropeginterferon as a promising disease-modifying therapy for high-risk essential thrombocythemia patients.
