Oxbryta’s withdrawal is a setback in the fight against sickle cell disease
The therapy was withdrawn from global markets due to safety concerns
Pfizer’s recent decision to withdraw Oxbryta (voxelotor) from global markets feels like a devastating blow for many people with sickle cell disease.
Oxbryta’s conditional approval in 2019 by the U.S. Food and Drug Administration gave hope to many, as few treatments exist for patients with sickle cell disease. The therapy was approved in the European Union in 2022.
As a sickle cell advocate who’s committed to raising awareness, I believe that improving health outcomes and access to treatment is what the fight is all about. This loss of a treatment option is a setback for our community.
For the many patients and families who rely on this medication to manage their condition, the uncertainty about what comes next must be overwhelming. Sickle cell disease is already an unpredictable and painful condition to live with; now, patients who found some relief from Oxbryta must work with their care provider to figure out next steps.
I’ve seen firsthand how important access to effective treatments is — for physical health as well as mental and emotional well-being. I was not eligible for Oxbryta, but I had hoped that as more treatments became available, I would be suitable for one of them. Many people living with sickle cell disease already experience anxiety about their health and future, which can be mentally exhausting.
A step backward
One of the most pressing concerns in the sickle cell community is whether the wider population, researchers, investors, and healthcare professionals really care about us. Sickle cell primarily affects people of African descent, and historically, this population has faced significant disparities in healthcare access and outcomes. The development and approval of Oxbryta was a win for our community, but its withdrawal feels like a step backward in our efforts to achieve equity.
After reading the reasons behind Pfizer’s decision, I agree that if the therapy’s benefits don’t outweigh its risks, withdrawing it from the market is the right decision. However, this raises questions about the clinical trials and safety testing conducted before the drug was approved. Why weren’t these safety issues raised sooner?
The relationship between Black people and clinical trials is already very fragile. This kind of news is likely to further fracture relationships between the Black community and research and development, as our marginalized population has once again been failed.
Despite this setback, I remain hopeful and determined to focus on the big picture. We should use the data and lessons learned from Oxbryta to develop better and safer therapies for people with sickle cell. There needs to be more research, more treatment options, and better access to care for our neglected patient population.
I urge the sickle cell community, healthcare professionals, and policymakers to come together and demand more viable alternatives. The narrative cannot be that approved treatments are failing sickle cell patients. We need action now.

I am a father who found my father's people when I was 37 years old. I found my lost sister and brother, and found my brother at the same time. I found my lost family, but my father died when he was 37 years old. I was not aware that there was a risk that I could pass on this disease. I had three of my children who have died from this disease, and my father and I have a granddaughter with SCD now and she is 17 years old. Please keep me up to date on this disease.
