FDA Issues Nyxoah an Approvable Letter for its Genio® System

Mont-Saint-Guibert, Belgium – March 26, 2025, 8:00am CET / 3:00am ET – Nyxoah SA (Euronext Brussels/Nasdaq: NYXH) (“Nyxoah” or the “Company”), that develops breakthrough treatment alternatives for Obstructive Sleep Apnea (OSA) through neuromodulation, today announced that the U.S. Food and Drug Administration (FDA) has issued an Approvable Letter regarding the Company's Pre-Market Approval (PMA) application for the Genio® system.

/EIN News/ -- The Approvable Letter means that Nyxoah’s application for marketing the device in the United States substantially meets the requirements of the Federal Food, Drug and Cosmetic Act and the FDA’s PMA implementing regulations codified at 21 C.F.R. Part 814, and the FDA will approve the application subject to satisfactory completion of a manufacturing facilities, methods and controls review. The Company will work closely with the FDA to address these requests and is committed to bringing this innovative therapy to U.S. patients.

“The FDA has reviewed our submission and determined that it substantially meets the requirements for approval: the FDA’s Approvable Letter included no further questions on the clinical data or biocompatibility that support the submission,” commented Olivier Taelman, Nyxoah’s Chief Executive Officer. “We are still on the right track to make Genio available to U.S. patients suffering from OSA.”

This decision does not impact Genio's CE Mark or ongoing commercial activities in Europe, where the device is approved for both Complete Concentric Collapse (CCC) and non-CCC patients.

Nyxoah is driven by the vision that OSA patients should enjoy restful nights and feel enabled to live their life to its fullest. 

Following the successful completion of the BLAST OSA study, the Genio® system received its European CE Mark in 2019.
