Possible treatments for two NBIA disorders are being tested in clinical trials that are either in progress or being planned for the near future.
The best known of these is the Retrophin Inc. trial for Pantothenate Kinase-Associated Neurodegeneration, or PKAN, now underway at 20 sites in the U.S., Canada and Europe. It is the first trial of a medication that targets the underlying causes of this disorder.
Retrophin, based in San Diego, finished enrolling patients in December 2018, with approximately 82 PKAN patients between the ages of 6 and 65 years. The Fosmetpantotenate Replacement Therapy, or FORT study, is being conducted under a Special Protocol Assessment agreement. That means the U.S. Food and Drug Administration believes that the trial’s design is adequate to support the filing of a New Drug Application, assuming the results are favorable.
