- Primary and key secondary endpoints showed statistically significant and clinically meaningful benefit in patients with mild to severe OSA
- Data showed evidence of durability-of-effect and improved quality-of-life and quality-of-sleep in open-label study extension
- AD109 was safe and well-tolerated
- Data from a second Phase 2 study (APC-004) in patients with less severe disease also reported today
CAMBRIDGE, Mass.--(BUSINESS WIRE)-- Apnimed, a clinical-stage pharmaceutical company focused on developing oral pharmacologic treatments to address obstructive sleep apnea (OSA) and related disorders, today announced positive data across multiple endpoints from a Phase 2 randomized, double-blind, placebo-controlled, four-period, single-dose crossover factorial clinical trial (APC-003), and a 28-day open-label extension study, evaluating AD109 as a treatment in patients with mild to severe OSA.
The randomized, placebo-controlled segment of the study showed that AD109 had a statistically significant and clinically meaningful difference from placebo after a single dose in the patients’ Hypoxic Burden (HB), which was the study’s primary endpoint. HB is a measure of the total amount of respiratory event-related hypoxemia, or low blood oxygen during sleep. The Apnea-Hypopnea Index (AHI), which was a secondary endpoint, which indicates the number of apnea (cessation of breathing) and hypopnea (shallow breathing) events per hour of sleep, demonstrated a similar reduction for AD109 relative to placebo. Additionally, during the open-label extension phase of this clinical trial, AD109 was shown to have a durability-of-effect when patients took AD109 for 28 days. Patients also experienced improvements in quality-of-life, nighttime breathing, and sleep across both objective and subjective measures.
“Today, we announced the findings from two key studies with our lead program AD109, which looked at two different populations of patients with OSA and different parameters of efficacy,” said Larry Miller, M.D., Chief Executive Officer of Apnimed. “Both of these studies demonstrate the potential of this oral pharmaceutical option to have a positive impact for patients in need of safe and easy-to-use solutions to address their disease. The results of Study APC-003 and its open-label extension provide strong evidence of durability-of-effect over 28 nights of treatment with AD109 and demonstrate improvements in the quality of the patients’ sleep across several key measures.”
Dr. Miller continued by saying, “Importantly, the open-label extension also looked at the impact of AD109 on the patient’s quality-of-life, using a gold standard assessment, the OSA-Specific Quality of Life Index (SAQLI), where patients reported statistically significant improvements in quality of life that suggest meaningful improvement in symptoms with chronic treatment. We look forward to confirming these findings and those of Study APC-004 in our planned Phase 2 MARIPOSA clinical trial, which will begin later this year.”
Apnimed also issued a press release today showcasing results from a second Phase 2 study, APC-004, exploring the safety and efficacy of AD109 in patients with mild to moderate OSA. For more information on that announcement, click here.
Study APC-003 and Open Label Extension Data Summary: A Phase 2 Clinical Trial in Patients with Mild to Severe OSA (NCT04580394)
This Phase 2 study was a randomized, double-blind, placebo-controlled, four-period, single-dose crossover factorial study in patients with mild to severe OSA. A total of 60 participants were enrolled. At bedtime during four overnight periods, each participant received one night of AD109, one night of each of the individual components that make up AD109 (aroxybutynin and atomoxetine), and one night of placebo.
Patients treated with AD109 had a large, statistically significant, and clinically meaningful difference from placebo in their HB (p
In addition, a four-week open-label extension was conducted that confirmed the efficacy and safety findings from the first segment of the study. Over four weeks of treatment with AD109, patients (n=37) had statistically significant and clinically meaningful reductions in HB (p
“The results from Study APC-003 are incredibly promising,” said James Maynard M.D., a principal investigator on the study from CTI Clinical Research Center (Cincinnati, OH). “With AD109 we are seeing clinically meaningful improvement in oxygenation and breathing during sleep as well as indications that these measures are improving over time, signaling the potential to see greater benefit the longer patients are on an oral treatment approach.”
The study also demonstrated a statistically significant (p
AD109 is Apnimed’s first-in-class, investigational, oral pharmacologic combination dosed once daily at bedtime, designed to treat OSA patients across a broad spectrum of disease severity. AD109 targets key neurological pathways in OSA that cause pathological upper airway closure during sleep. AD109 combines a selective norepinephrine reuptake inhibitor (atomoxetine) with Apnimed’s novel new chemical entity (NCE) – a selective antimuscarinic (aroxybutynin) - to activate the upper airway dilator muscles and maintain an open airway during sleep. The investigational drug combination is designed to be safe, effective, and convenient, addressing the key limitations of the current standard of care treatments, and is currently in Phase 2 clinical trials.
About Obstructive Sleep Apnea
Obstructive Sleep Apnea (OSA) is one of the most common and serious sleep disorders and is estimated to affect more than 25 million Americans, though underdiagnosis continues to be a serious problem. OSA is characterized by partial or complete upper airway closure that occurs during sleep, which often leads to poor sleep, and in the long-term has been shown to exacerbate hypertension, diabetes, cardiovascular disease, and stroke. Additionally, OSA can impair work productivity, reduce functional ability, and lower quality of life.
Sleep-related muscular relaxation driven by the central nervous system is the key neurologic mechanism leading to OSA. In patients with OSA, sleep onset leads to a reduction in neuromuscular control of the upper airway and a corresponding relaxation of the upper airway dilator muscles. The vast majority of diagnosed patients are prescribed positive air pressure therapy devices such as continuous positive airway pressure, or CPAP, but many patients are dissatisfied with these mechanical nighttime devices and fewer than half are compliant long-term, leaving a significant population untreated, undertreated, and at risk.
Apnimed is a clinical-stage pharmaceutical company working to transform the treatment of sleep apnea based on a simple idea – patients with Obstructive Sleep Apnea will benefit from treatment with a safe and effective oral medication. Apnimed’s lead development program targets the neurologic control of upper airway muscles to maintain an open airway during sleep. The drug is delivered as a convenient once-daily at bedtime. Based in Cambridge, Mass., the company is developing a portfolio of novel pharmacologic therapies for sleep apnea and related disorders. Learn more at apnimed.com
