Protagonist and Takeda announced positive Phase 3 VERIFY study results for rusfertide in treating polycythemia vera (PV), to be presented at ASCO. The study met its primary endpoint with 76.9% of patients on rusfertide plus standard care achieving clinical response vs 32.9% in placebo group. Key findings include a reduction in required phlebotomies (0.5 vs 1.8 per patient) and improved hematocrit control (62.6% vs 14.4% maintaining levels below 45%).
