          The Food and Drug Administration on Friday approved the world’s first medicine based on CRISPR gene-editing technology, a groundbreaking treatment for sickle cell disease that delivers a potential cure for people born with the chronic and life-shortening blood disorder.

          The new medicine, called Casgevy, is made by Vertex Pharmaceuticals and CRISPR Therapeutics. Its authorization is a scientific triumph for the technology that can efficiently and precisely repair DNA mutations — ushering in a new era of genetic medicines for inherited diseases.

          In a clinical trial, Casgevy was shown to eliminate recurrent episodes of debilitating pain caused by sickle cell, which afflicts approximately 100,000 people in the U.S., a vast majority of whom are Black. The therapy, whose scientific name is exa-cel, is described as a potential cure because the genetic fix enabled by CRISPR is designed to last a lifetime, although confirmation will require years of follow-up.
