DREAM U.S. Pivotal Study

On September 27, 2024, Nyxoah SA (the “Company”) announced that data from its DREAM U.S. pivotal study were presented in an oral session at the International Surgical Sleep Society (“ISSS”) 2024 Educational Update.

In particular, additional data were presented for Apnea-Hypopnea Index (“AHI”) reduction in supine and non-supine positions. Genio bilateral stimulation resulted in a clinically meaningful 71.0% median reduction in supine AHI at 12 months compared with baseline. This reduction compares to a median 12-month AHI reduction of 70.8% across all sleeping positions.

With respect to secondary endpoints reported at ISSS, subjects demonstrated significant improvements in quality-of-life outcomes. Specifically, a mean increase of 2.3 points was observed in the Functional Outcomes of Sleep Questionnaire assessment. Additionally, the Epworth Sleepiness Score was reduced by a mean of 3.4 points from baseline.

The presentation included previously announced data demonstrating that the study achieved its co-primary endpoints of 12-month AHI responder rate, per the Sher criteria, and Oxygen Desaturation Index (“ODI”) responder rate, both on an Intent-To-Treat (“ITT”) basis. In the DREAM U.S. pivotal study, 115 patients received the Genio® implant and were included in the safety analysis. These patients had a mean AHI of 28.0, mean ODI of 27.0 and mean body mass index of 28.5 at baseline. At 12 months, 73 subjects were determined to be AHI responders, per the Sher criteria, resulting in an ITT AHI responder rate of 63.5% (p=0.002), and 82 subjects were determined to be ODI responders, resulting in an ODI responder rate of 71.3% (p<0.001). Safety results were in line with other neuromodulation therapies, with 11 serious adverse events (“SAEs”) in ten subjects resulting in an SAE rate of 8.7%. Out of the 11 SAEs, three were device related, and there were three explants.

The information included under the heading “DREAM U.S. Pivotal Study” of this report on Form 6-K shall be deemed to be incorporated by reference into the registrationstatements on Form S-8 (Registration Numbers 333-261233 and 333-269410) and Form F-3 (Registration Number 333-268955) of the Company(including any prospectuses forming a part of such registration statements) and to be a part thereof from the date on which this reportis filed, to the extent not superseded by documents or reports subsequently filed or furnished.

DREAM Pivotal Study Data Presented at the InternationalSurgical Sleep Society 2024 Educational Update


Additional clinical data on patients sufferingfrom Obstructive Sleep Apnea (OSA) demonstrate a clinically significant 71.0% median reduction in Apnea-Hypopnea index (AHI) while sleepingsupine

at 12 months compared with baseline.

82.0% of patients who completed a polysomnographyat 12 months had an AHI below 15, and 67.4% of patients who completed a polysomnography at 12 months had an AHI below 10.

Mont-Saint-Guibert, Belgium – September27, 2024, 10:30pm CET / 4:30pm ET – Nyxoah SA (Euronext Brussels/Nasdaq: NYXH) (“Nyxoah” or the “Company”), a medical technology company that develops breakthrough treatment alternatives for Obstructive Sleep Apnea (OSA) through neuromodulation, announced that data from the DREAM U.S. pivotal study were presented in an oral session at the International Surgical Sleep Society (ISSS) 2024 Educational Update, taking place from September 26 -27 in Miami, Florida.

Additional data were presented for AHI reduction in supine and non-supine positions. Genio bilateral stimulation resulted in a clinically meaningful 71.0% median reduction in supine AHI at 12 months compared with baseline. This reduction compares to a median 12-month AHI reduction of 70.8% across all sleeping positions.

With respect to secondary endpoints reported at ISSS, subjects demonstrated significant improvements in quality-of-life outcomes. Specifically, a mean increase of 2.3 points was observed in the Functional Outcomes of Sleep Questionnaire (FOSQ) assessment. Additionally, the Epworth Sleepiness Score was reduced by a mean of 3.4 points from baseline.

The presentation included previously announced data demonstrating that the study achieved its co-primary endpoints of 12-month AHI responder rate, per the Sher criteria, and Oxygen Desaturation Index (ODI) responder rate, both on an Intent-To-Treat (ITT) basis. In the DREAM U.S. pivotal study, 115 patients received the Genio^®^ implant and were included in the safety analysis. These patients had a mean AHI of 28.0, mean ODI of 27.0 and mean body mass index of 28.5 at baseline. At 12 months, 73 subjects were determined to be AHI responders, per the Sher criteria*, resulting in an ITT AHI responder rate of 63.5% (p=0.002), and 82 subjects were determined to be ODI responders, resulting in an ODI responder rate of 71.3% (p<0.001). Safety results were in line with other neuromodulation therapies, with 11 serious adverse events, or SAEs, in ten subjects resulting in an SAE rate of 8.7%. Out of the 11 SAEs, three were device related, and there were three explants.

*An AHI responder, per the Sher criteria, is defined as a subject with an AHI reduction of at least 50% from baseline and an AHI score of less than 20 events per hour on the 12-month PSG. An ODI responder is defined as a subject which demonstrates an ODI reduction of at least 25% from baseline on the 12-month PSG.

“The DREAM study demonstrated efficacy of bilateral hypoglossal nerve stimulation using Genio for the treatment of obstructive sleep apnea. Clinically significant improvements in primary and secondary endpoints were observed,” said B. Tucker Woodson, MD, Chief, Professor – Medical College of Wisconsin and Principal Investigator of the DREAM study. “Genio has the potential of helping us advance neuromodulation therapy for the treatment of OSA.”

“Achieving meaningful AHI reductions regardless of sleep position is a clinical validation of our patient-centric approach,” said Olivier Taelman, CEO of Nyxoah. “Genio bilateral stimulation also enabled more than 80% of patients to hit 12 months with an AHI below 15, positively impacting their overall quality of life and reducing sleepiness. Nyxoah is now entering the final regulatory phase and is progressing toward FDA approval. This will be a huge milestone in our mission to make Genio available to OSA patients in the US.”
