FDA Approves Drug to Treat Neurologic Manifestations of Hunter Syndrome

WHY IT MATTERS

This is the first FDA approval of Avlayah specifically for the neurologic manifestations of Hunter syndrome, offering patients a new therapeutic option for managing brain and nervous system symptoms that were previously difficult to treat.

The FDA has approved a new drug called Avlayah to treat Hunter syndrome, a rare genetic disease that affects the brain and nervous system. Hunter syndrome happens when the body can't break down certain substances properly, causing serious health problems over time. This approval means patients with Hunter syndrome now have a new treatment option available to help manage the neurologic symptoms of their condition.

The U.S. Food and Drug Administration approved Avlayah (tividenofusp alfa-eknm) to treat certain individuals with Hunter syndrome (Mucopolysaccharidosis type II or MPS II).

YOU CAN ACT ON THIS

If you or a family member has Hunter syndrome, talk to your doctor right away about whether Avlayah might be appropriate for your specific situation and how to access it.
