About Nyxoah

Nyxoah is reinventing sleep for the billion people that suffer from obstructive sleep apnea (OSA). We are a medical technology company that develops breakthrough treatment alternatives for OSA through neuromodulation. Our first innovation is Genio®, a battery-free hypoglossal neuromodulation device that is inserted through a single incision under the chin and controlled by a wearable. Through our commitment to innovation and clinical evidence, we have shown best-in-class outcomes for reducing OSA burden.

Following the successful completion of the BLAST OSA study, the Genio® system received its European CE Mark in 2019. Nyxoah completed two successful IPOs: on Euronext Brussels in September 2020 and NASDAQ in July 2021. Following the positive outcomes of the BETTER SLEEP study, Nyxoah received CE mark approval for the expansion of its therapeutic indications to Complete Concentric Collapse (CCC) patients, currently contraindicated in competitors' therapy. Additionally, the Company announced positive outcomes from the DREAM IDE pivotal study for FDA and U.S. commercialization approval.

Caution – CE marked since 2019. Investigational device in the United States. Limited by U.S. federal law to investigational use in the United States.
