FDA Approves Daybue (trofinetide) for the Treatment of Rett Syndrome
Acadia Pharmaceuticals Inc. announced that the U.S. Food and Drug Administration (FDA) has approved Daybue (trofinetide) for the treatment of Rett syndrome in adult and pediatric patients two years of age and older. Daybue is the first and only drug approved for the treatment of Rett syndrome.
Rett syndrome is a complex, rare, neurodevelopmental disorder typically caused by a genetic mutation on the MECP2 gene. It is characterized by a period of normal development until six to 18 months of age, followed by significant developmental regression with loss of acquired communication skills and purposeful hand use. Symptoms of Rett syndrome may also include development of hand stereotypies, such as hand wringing and clapping, and gait abnormalities. Rett syndrome is believed to affect 6,000 to 9,000 patients in the U.S.,with a diagnosed population of approximately 4,500 U.S. patients. Daybue is not recommended for patients with moderate or severe renal impairment.
Daybue™ is expected to be available in the U.S. by the end of April, 2023.
