AGIO Hits 52-Week Low Amid Trial Setbacks
Shares of Agios Pharmaceuticals (AGIO.O) plummeted approximately 45% in premarket trading today, marking a new 52-week low for the stock. The significant decline follows mixed results from the late-stage RISE UP trial of mitapivat for sickle cell disease, where the primary endpoint for hemoglobin response was met, but the treatment failed to demonstrate a meaningful reduction in pain crises. Furthermore, serious adverse events were reported in both the treatment and placebo groups, raising concerns among investors. Looking ahead, Agios plans to engage with the U.S. FDA in early 2026 to discuss a marketing application for mitapivat, while also aiming to streamline expenses to facilitate the potential launch of Pyrukynd for thalassemia.
