Oxbryta Lawsuit Overview
Oxbryta (voxelotor), a drug approved in 2019 to treat sickle cell disease, is now the subject of growing legal action. Originally hailed as a breakthrough therapy, Oxbryta has since been linked to life-threatening complications including vaso-occlusive crises (VOC), strokes, seizures, and death.
Patients and families across the U.S. are filing lawsuits against Global Blood Therapeutics (now a Pfizer subsidiary), claiming they were never warned of these serious risks. The lawsuits allege that the company failed to disclose key side effects and put vulnerable patients at grave risk.
