CAMBRIDGE, Mass., Sept. 08, 2026 (GLOBE NEWSWIRE) — Apnimed, Inc. (Nasdaq: APMD) (“Apnimed”), a late stage clinical pharmaceutical company dedicated to the discovery, development and commercialization of novel oral therapies that address the neurobiology of sleep-related breathing diseases, today announced its financial results for the second quarter ended June 30, 2026, and provided a corporate update. 

“This was a highly productive quarter for Apnimed as we continued to execute against our strategy, highlighted by the FDA’s acceptance of our NDA for AD109 (proposed proprietary name Oxnimbi), with a PDUFA target action date of February 28, 2027,” said Kevin Lind, Chief Executive Officer of Apnimed. “Over the past several months, we have significantly strengthened our financial position, including through the successful completion of our IPO, providing us with additional resources as we prepare for the potential commercialization of Oxnimbi, pending approval. With this strengthened financial position, we are advancing our commercial readiness activities and building the capabilities needed to support a potential U.S. launch. With an estimated 80 million people in the U.S. living with OSA, many of whom remain untreated, we believe Oxnimbi has the potential to address the scale of unmet need in OSA and, if approved, represents a significant commercial opportunity for Apnimed.” 

Recent Highlights and Upcoming Milestones 

• Announced the FDA accepted for review the New Drug Application (“NDA”) for AD109 (proposed proprietary name Oxnimbi) for the treatment of adults with obstructive sleep apnea (“OSA”). The FDA has assigned a Prescription Drug User Fee Act (“PDUFA”) target action date of February 28, 2027. 
• Presented a broad body of data and research at both ATS 2026 and SLEEP 2026, including pooled analyses of the SynAIRgy and LunAIRo Phase 3 trials of Oxnimbi, reflecting one of the largest clinical development programs conducted for an OSA pharmacotherapy, as well as research highlighting the significant unmet need in OSA.  
• Simultaneously published two peer-reviewed articles on Oxnimbi, including results from the Phase 3 SynAIRgy trial in the American Journal of Respiratory and Critical Care Medicine and a companion mechanistic review article in the American Journal of Respiratory Cell and Molecular Biology. 
• Strengthened the Company’s leadership team with the appointments of Kevin Lind as Chief Executive Officer, Michael Kelly as Chief Financial Officer and Steven Spector as Chief Legal Officer and Head of Corporate Affairs as part of a planned leadership transition.

• Completed the strategic monetization of the Company’s interest in Shionogi-Apnimed Sleep Science, generating $100 million in upfront proceeds, with the potential for additional milestone and royalty payments, while allowing the Company to further focus its resources on Oxnimbi. 
• Apnimed’s common stock began trading on the Nasdaq Global Select Market under the ticker symbol “APMD” on July 31, 2026.

Second Quarter Financial Results 
Apnimed reported cash and cash equivalents of approximately $172.8 million at June 30, 2026. Subsequently, the Company completed its upsized initial public offering of 13,800,000 shares of its common stock, including 1,800,000 shares issued pursuant to the full exercise of the underwriters’ overallotment option, at a price to the public of $16.00 per share for gross proceeds of $220.8 million, less underwriting discounts and commissions.   

Research and development expenses were $9.9 million for the three months ended June 30, 2026, a decrease of $6.1 million, or 38%, compared to $16.0 million for the three months ended June 30, 2025. The net decrease was primarily driven by $7.6 million lower clinical trial expense related to AD109 (proposed proprietary name Oxnimbi) as LunAIRo and SynAIRgy trials were completed in 2025, and $0.1 million decrease in other projects expense. This decrease was partially offset by an increase of $1.6 million in medical affairs expense due to increased Key Opinion Leader engagement in 2026.  

General and administrative expenses were $12.7 million for the three months ended June 30, 2026, an increase of $7.3 million, or greater than 100%, compared to $5.4 million for the three months ended June 30, 2025. The net increase was primarily related to increases of $3.0 million in legal services incurred related to business consulting and contract negotiations, and increased salary expense due to increased headcount, $4.0 million in infrastructure to prepare us, the market, and our brand for the expected launch of Oxnimbi, if approved, including key areas such as education on the unmet needs in OSA, pricing strategy, forecast estimates, market access planning, product positioning and stakeholder messaging, and $0.3 million in stock-based compensation related to increased headcount.  

Other income (expenses) was $137.8 million for the three months ended June 30, 2026, an increase of $137.5 million, or greater than 100%, compared to $0.3 million for the three months ended June 30, 2025. The net increase is primarily related to a $57.1 million gain on reversal of deposit liability, an $85.4 million gain on sale of equity method investment, a $0.6 million increase in interest income, and a change in other income of $0.1 million due to the change in fair value of the contingent asset, offset by a $2.9 million combined change in fair value of long-term debt, revenue interest liability, and the convertible notes, and an increase in other expense related to $2.9 million of long-term debt and revenue interest liability issuance costs.

Net income was $125.9 million for the quarter ended June 30, 2026, compared to a net loss of $69.5 million for the quarter ended June 30, 2025. The increase was primarily attributable to the factors impacting the Company’s expenses and other income described above.

About AD109 / Oxnimbi 
AD109 is Apnimed’s investigational drug candidate, with a proposed proprietary name of Oxnimbi. The proposed name remains subject to final FDA review and acceptance and may change. Oxnimbi is designed to be the first potential pharmacological treatment to improve oxygenation during sleep and target the neuromuscular root cause of upper airway collapse in people with OSA. It is a potentially first-in-class combination of aroxybutynin, a novel antimuscarinic, and atomoxetine, a selective norepinephrine reuptake inhibitor. Oxnimbi is intended to be a once-daily oral pill taken at bedtime that is designed to lower the complexity of treating OSA. Oxnimbi, if approved, may offer an oral solution to help improve oxygenation and health for people living with OSA. Oxnimbi has completed two Phase 3 clinical trials for the treatment of mild, moderate and severe OSA. Apnimed’s NDA for Oxnimbi is under review by the FDA and was assigned a PDUFA goal date of February 28, 2027. There can be no assurances that Oxnimbi will be approved by the FDA by the PDUFA target action date, or at all.  

About Apnimed   
Apnimed is a late stage clinical pharmaceutical company dedicated to the discovery, development and commercialization of novel oral therapies that address the neurobiology of sleep-related breathing diseases. We believe the introduction of once-nightly oral drugs has the potential to expand diagnosis and the reach of treatment for people with OSA. We believe that people with OSA would benefit from having multiple treatment options with differing mechanisms to more fully address the heterogeneity of OSA’s disease pathophysiology. Apnimed envisions a new era where novel oral therapies simplify intervention and expand the reach of diagnosis and treatment.

Apnimed is advancing its product candidate, AD109 (proposed proprietary name Oxnimbi), which is designed to improve oxygenation in individuals living with OSA. We believe that Oxnimbi could become the catalyst for a new oral treatment paradigm for OSA that has been historically limited to devices or invasive surgeries.
