The short answer

Avlayah (tividenofusp alfa-eknm) is an FDA-approved brain-penetrant enzyme replacement therapy made by Denali Therapeutics. The FDA approved it on 24 March 2026 for Hunter syndrome (MPS II) affecting the brain. We found no approval outside the United States in public sources as of 13 October 2026. We found no Gulf registration in public sources as of 13 October 2026. In Saudi Arabia, the UAE, Kuwait and Qatar, the legal route is usually a named-patient request: the treating hospital asks the national regulator for permission to import it for one patient. We give you a written timeline estimate for your case before you commit.
