Nyxoah SA , a medical technology company that develops breakthrough treatment alternatives for Obstructive Sleep Apnea (OSA) through neuromodulation, announced that the U.S. Food and Drug Administration (FDA) has approved the Genio system for a subset of patients with moderate to severe OSA with an Apnea-Hypopnea Index (AHI) of greater than or equal to 15 and less than or equal to 65.

Genio is a different approach to hypoglossal nerve stimulation (HGNS) for the treatment of OSA. Genio’s unique design utilizes bilateral stimulation, and offers patients a leadless, full-body 1.5T and 3T MRI compatible, non-implanted battery solution, powered and controlled by a wearable component. The wearable component is fully upgradable, providing Genio patients with access to this technology without requiring additional surgeries for technology updates or battery replacements.

"Today marks a defining moment for Nyxoah and for U.S. patients suffering from OSA. With the FDA’s marketing approval of the Genio system, we are proud to bring this innovative therapy to the U.S. market,” commented Olivier Taelman, Nyxoah’s Chief Executive Officer. “Our mission has always been to make sleep simple for OSA patients by offering them a solution that empowers better sleep. We look forward to the successful execution of our U.S. commercialization strategy.”
        
The Genio system’s FDA approval was supported by the high-quality, differentiated safety and efficacy data from the Company's DREAM pivotal trial. The DREAM study met both its primary and secondary endpoints demonstrating an AHI responder rate of 63.5% and an Oxygen Desaturation Index responder rate of 71.3%, with an overall median AHI reduction of 70.8%. Additionally, 82.0% of all DREAM subjects saw their AHI scores drop below 15 or lower.

Importantly, the DREAM study demonstrated that Genio is efficacious regardless of a patient's sleeping position and, to our knowledge the only therapy with such clinical evidence in a large, multicenter, prospective clinical study using data from a full night polysomnography. This is a critical differentiator as on average, people sleep in a supine position between 35% and 40% of the night. The DREAM study measured position-specific outcomes and demonstrated a 66.6% median AHI reduction while patients slept in a supine position despite the fact that the number of airway obstructions can double in this position. This reduction compares favorably to the 71.0% reduction in AHI shown while patients slept in a non-supine position.

"The Genio system's approval represents a major addition to the treatment options available to physicians treating patients with OSA,” said Colin Huntley MD, Associate Professor, Department of Otolaryngology Head & Neck Surgery, Thomas Jefferson University. “This unique bilateral stimulation technology has demonstrated consistent efficacy across all sleeping positions, including the challenging supine position, while maintaining an excellent safety profile.”
