Why Oxbryta Mass Tort Matters
In 2019, Oxbryta (voxelotor), developed by Global Blood Therapeutics and later acquired by Pfizer, was introduced as a groundbreaking treatment for sickle cell disease. It was designed to improve oxygen binding to hemoglobin and reduce painful crises.
However, by September 2024, Pfizer voluntarily withdrew the drug worldwide after emerging data showed increased risks of death and complications. As of August 2025, lawsuits are growing nationwide, making Oxbryta A Mass Tort one of the most significant pharmaceutical litigations in recent years.
Understanding Oxbryta’s Side Effects
While Oxbryta initially offered hope by reducing anemia and vaso-occlusive crises (VOCs), post-marketing surveillance revealed severe risks. Clinical trials and real-world data confirmed adverse effects that ultimately triggered the recall.
Serious Side Effects Linked to Oxbryta
- Increased vaso-occlusive crises (VOCs) leading to organ damage and intense pain
- Higher mortality rates compared to placebo groups
- Severe allergic reactions, including swollen glands, difficulty swallowing, and high fever
- Black, tarry stools, chest pain, chills, hives, itching, and painful urination
- Tissue damage progression, in some cases escalating to tissue death
Additional post-recall analyses reported links to strokes, organ failure, and fatal events. Patients are advised to seek immediate medical care if they experience these symptoms and discuss alternatives like hydroxyurea with their doctors.
Lawsuits Against Pfizer
The recall has triggered a growing number of lawsuits accusing Pfizer and GBT of negligence, misrepresentation, and failure to warn about Oxbryta’s risks.
Notable Cases
- Trebor Hardiman Case (October 2024): Filed in California, alleging severe injuries caused by Oxbryta.
- Wrongful Death in Tennessee (June 2025): A widow sued Pfizer, linking her husband’s death to Oxbryta complications.
- Consolidated Actions: By mid-2025, at least eight lawsuits were filed nationwide, with more expected.
Current Status
- Trial Dates: A bellwether trial in California is scheduled for September 2027.
- Growth in Filings: New lawsuits continue to emerge, consolidating into federal actions.
The plaintiffs with Oxbryta cases include sickle cell patients who suffered strokes, organ failure, wrongful death, and severe VOCs.
