  "account": "The FDA has delayed a decision on Agios Pharmaceuticals' supplemental New Drug Application (sNDA) seeking additional approval for the drug mitapivat in sickle cell disease (SCD) until February 1, 2027. The delay was triggered by a major amendment to the sNDA, requiring additional information to assess the need for a Risk Evaluation and Mitigation Strategy (REMS). Agios submitted updated safety data from the ongoing open-label extension periods of the Phase II/III RISE UP trial, showing a hemoglobin response in 41% of patients compared to 3% on placebo. Serious adverse events were reported in 20% of patients on mitapivat versus 29% on placebo. Despite the delay, Agios remains confident in mitapivat's potential to transform care for people with sickle cell disease, as the drug has a confirmed risk-benefit profile and management expects no additional delays.",
