FDA approves Nashville doctor's potential cure for sickle cell disease

Thirteen-year-old Rickey Buggs, III, recently celebrated being freed from a life-threatening blood disorder with a plate of Olive Garden spaghetti and birthday cake at a Nashville hospital.

Rickey's painful crises from sickle cell disease led to repeated emergency room visits and hospital stays throughout his childhood. Now, after undergoing a groundbreaking gene-editing therapy, he is likely cured of the inherited disorder, said Dr. Haydar Frangoul, a pediatric hematologist-oncologist at TriStar Centennial Children's Hospital who helped pioneer the treatment.
