In a historic milestone for medicine, patients with sickle cell disease are being cured through CRISPR gene editing therapy. Casgevy, approved by the FDA in late 2023, has now treated hundreds of patients with remarkable success.

“Casgevy, approved by the FDA in late 2023, has now treated hundreds of patients with remarkable success.”
