T1 A budget impact analysis of gene therapy for sickle cell disease: an updated analysis JF Blood Advances JO Blood Adv YR 2024 DO 10.1182/bloodadvances.2024013093 VO 8 IS 17 SP 4658 OP 4661 SN 2473-9529 AB TO THE EDITOR:In December 2023, the US Food and Drug Administration (FDA) approved 2 gene therapies for sickle cell disease (SCD). The data demonstrated substantial short-term clinical improvement.1,2 Approximately half of the 100 000 individuals in the United States with SCD are Medicaid enrollees.3 Allogeneic hematopoietic stem cell transplant (HSCT) is a well-described cure for the hemoglobinopathy, although its use is limited due to donor availability and toxicity.4Prices for gene therapies have made headlines, whereas the payment timing and uncertainty in treatment durability compound the challenge for payers.5 The 2 new approvals for SCD apply to a population far larger than any existing commercial gene therapy.
