Mont-Saint-Guibert, Belgium – 17th November 2020 – Nyxoah S.A. (EBR: NYXH) (“Nyxoah” or the “Company”), a health-technology company focused on the development and commercialization of innovative solutions and services to treat sleep disordered breathing conditions, today announces the successful implantation of the first patient in the DREAM US pivotal FDA study. The implantation took place at Hollywood Private Hospital in Perth, Australia and was performed by Dr. Richard Lewis, MBBS, FRACS, Head & Neck Surgeon.

The DREAM (Dual-sided Hypoglossal neRvE stimulAtion for the treatMent of Obstructive Sleep Apnea) study is a pivotal, Investigational Device Exemption (IDE) trial designed to support the marketing authorization of the Genio® system in the United States. This multicenter, prospective, open-label, observational study will enroll 134 patients, who will undergo the implantation procedure in up to 26 centers worldwide including sites in the United States, Germany, Belgium and Australia.

Dr. Richard Lewis, implanting surgeon from Hollywood Private Hospital commented: “ Our center has an extensive historical collaboration with Nyxoah. We took part in the BLAST OSA study that led to CE Mark approval of the Genio® system and we are the lead investigator center in the ongoing BETTER SLEEP study testing the effectiveness of hypoglossal nerve stimulation on Complete Concentric Collapse (CCC) patients who are currently excluded from this type of therapy. We are excited to be part of the DREAM IDE pivotal trial together with US and European physicians and are thrilled to build further clinical evidence on the Genio® system giving more patients across the globe access to this innovative OSA therapy.“

Olivier Taelman, Chief Executive Officer of Nyxoah, added: “The United States are the largest market in the world for the treatment of patients suffering from Obstructive Sleep Apnea. The DREAM study is designed to support the U.S. introduction of the Genio® system. Enabling US physicians to build their first experience with the Genio® system, combined with the knowledge of other already experienced international surgeons, is supporting Nyxoah’s mission to offer its disruptive therapy to more OSA
patients around the world.
