Mifepristone Orphan Drug Status for Cushing's Syndrome Secondary to ACTH Secretion in EU
On July 27, the European Commission approved orphan drug status for mifepristone (made by Laboratoire HRA Pharma, France) in the treatment of Cushing's syndrome secondary to ectopic adrenocorticotrophic hormone (ACTH) secretion. The condition affects fewer than 5,000 individuals in the European Union (EU).
The product acts as a reversible competitive antagonist at cortisol receptors, thereby decreasing the effects of elevated cortisol levels and improving long-term outcome.
Mifepristone (made by HRA Pharma) was approved for this orphan drug indication by the U.S. Food and Drug Administration (FDA) in February 2005. Mifepristone was also granted traditional approval by the FDA in September 2000 for the medical termination of intrauterine pregnancies.
