ProSomnus® Announces FDA 510(k) Clearance for ProSomnus EVO™ [PH] Sleep and Snore Device

Device expands ProSomnus’ suite of FDA-cleared Precision Oral Appliance Therapy Devices for treatment of Obstructive Sleep Apnea (OSA)

Device is engineered to provide Medicare beneficiaries and their healthcare providers with new options for treating OSA

SAN FRANCISCO, Nov. 02, 2022 (GLOBE NEWSWIRE) — ProSomnus (“the Company”), a pioneer in precision medical devices for the treatment of Obstructive Sleep Apnea (OSA), today announced that it has received 510(k) clearance from the United States Food and Drug Administration (FDA) for the ProSomnus EVO™ [PH] Sleep and Snore Device. The device joins the Company’s flagship product, the ProSomnus EVO™, in its line of FDA-cleared, patient-preferred, less invasive Precision Oral Appliance Therapy (OAT) devices for the treatment of OSA.

The ProSomnus EVO [PH] Sleep and Snore Device is specifically engineered to meet Centers for Medicare Services coding guidelines, offering Medicare beneficiaries a non-invasive, comfortable, easy-to-use, and effective alternative to CPAP machines, surgical procedures, and legacy oral devices. Per Medicare coding guidelines, the ProSomnus EVO [PH] device uses mechanical hinge components to precisely reposition and stabilize the patient’s jaw during sleep, increasing pharyngeal space and reducing the risk of upper airway collapse. The device is approximately 13% smaller than predicate devices and features unique comfort bumps around key components. The device features unique advancement markings and visual indicators to make it easier for beneficiaries to communicate with their healthcare providers throughout treatment.

Every ProSomnus EVO [PH] device is personalized and digitally manufactured based upon the patient’s unique anatomy and healthcare provider’s treatment plan for each patient. The ProSomnus EVO [PH] is the only Herbst-style device made from engineered, Medical Grade Class VI-rated material, the highest material quality grade offered by US Pharmacopeia.

“Receiving FDA clearance for the ProSomnus EVO [PH] is a significant milestone for the Company and for patients suffering from OSA,” said Len Liptak, Co-Founder and Chief Executive Officer of ProSomnus. “This expands our industry-leading suite of FDA-cleared precision medical devices to treat OSA, offering patients and their healthcare providers yet another alternative to CPAP, surgery and legacy oral appliances. Successfully addressing OSA starts with giving patients a treatment that is safe, effective, and easier to adhere to, and the EVO [PH] is one more patient-preferred Precision OAT option available to them.”

“This latest FDA milestone is a big step in making Precision OAT available to as many patients as possible,” said John E. Remmers, MD, Chief Scientist of ProSomnus. “Despite the alarming prevalence of OSA and its dire consequences, legacy OSA treatments have not improved at a rate that patients deserve, especially in light of the current issues with CPAP treatment. This makes our commitment to developing less invasive therapies even more important, and we look forward to the difference it will make for patients and providers.”

“Our manufacturing platform allows us to advance the quality of our materials. We are continuously expanding our material selection far beyond dental applications and researching and developing innovative medical grade polymers for our products,” commented Sung Kim, Co-Founder and Chief Technology Officer of ProSomnus. “The improved flexibility of the ProSomnus EVO [PH] makes it even easier for patients to use, while its durability protects it from accidental drops. In addition to being incredibly stain-resistant, the EVO [PH] is precision milled in one piece, so it maintains its fit throughout treatment without deformation, staining or harboring bioburden, unlike soft liner and nylon materials.”

About OSA
OSA is the recurring collapse of the airway during sleep, resulting in oxygen shortages and abrupt awakenings accompanied by gasping or choking. In addition to daytime sleepiness, OSA is associated with serious comorbidities, including heart failure, stroke, hypertension, morbid obesity and type 2 diabetes. Patients with untreated OSA are 23 times more likely to suffer a heart attack and four times more likely to have a stroke. It is estimated that more than one billion people worldwide and over 74 million people in North America suffer from OSA. Approximately 56 million of those 74 million people in North America are undiagnosed.
