A new treatment for children aged 2 or older with sickle cell disease has been approved by the U.S. Food & Drug Administration. In a press release on Wednesday, the FDA announced it had approved Casgevy, the first gene therapy for children with sickle cell disease. (NewsNation) — A new treatment for children aged 2 or older with sickle cell disease has been approved by the Food & Drug Administration (FDA). In a Wednesday news release, the FDA announced it had approved Casgevy, the first gene therapy for children with the disease. “Casgevy is a gene therapy consisting of the patient’s own (autologous) hematopoietic (blood) stem cells, administered as a one-time single dose for intravenous infusion,” the release noted. “Pediatric patients as young as 2 years of age can now access a critical additional treatment option to treat these debilitating, life-threatening diseases,” Karim Mikhail, the acting director of the Center for Biologics Evaluation and Research, wrote. “These disorders carry a heavy burden for children and their families, affecting growth, development, and long-term health in profound ways,” Megha Kaushal, acting deputy director of the Office of Therapeutic Products in CBER, said in the release.
