Optinose Announces FDA Acceptance of Supplemental New Drug Application for XHANCE
The application is based on phase 3 results from the ReOpen clinical trial program showing XHANCE significantly reduced symptoms and sinus opacification in participants with chronic rhinosinusitis
If approved, XHANCE is expected to be the first and only drug indicated for the treatment of chronic rhinosinusitis, a diagnosis which is assigned at approximately 10 million patient visits annually
YARDLEY, Pa., May 4, 2023 Optinose (NASDAQ:OPTN), a pharmaceutical company focused on patients treated by ear, nose and throat (ENT) and allergy specialists, today announced the U.S. Food and Drug Administration (FDA) accepted for review its supplemental new drug application (sNDA) requesting approval of XHANCE as a treatment for chronic rhinosinusitis. XHANCE® (fluticasone propionate) nasal spray is a drug-device combination product that combines the most widely used nasal anti-inflammatory drug with the innovative Exhalation Delivery System™ (EDS™). The EDS is designed to uniquely deliver drug high and deep into difficult-to-access sinuses and sinonasal drainage tracts. The sNDA submission is based on data from the two Phase 3 clinical trials in patients with chronic sinusitis from the ReOpen Program and has been assigned a Prescription Drug User Fee Act (PDUFA) target goal date of December 16, 2023.
“Chronic sinusitis is one of the top diagnoses made in adult outpatient visits, with approximately 10 million physician office visits coded annually, yet there is a high level of patient dissatisfaction and suffering and no FDA approved drug treatments except for patients who also have nasal polyps,” stated Ramy Mahmoud, MD, MPH, CEO of Optinose. “We are excited to see our study data under FDA review as we believe the ReOpen trials found important benefits that XHANCE could offer to physicians and their patients as a first-ever drug approved to treat chronic rhinosinusitis.”
About the ReOpen Program The ReOpen program comprised two global, randomized, double-blind, placebo-controlled Phase 3 trials that evaluated the efficacy and safety of one or two sprays of XHANCE (OPN-375) in each nostril twice daily, over 24 weeks, in patients suffering from chronic sinusitis (CS). In ReOpen1, the first of the two trials, 332 CS patients were treated, either with or without concurrent nasal polyps. In ReOpen2, the second of the two trials, 222 CS patients were treated, all of whom did not have polyps in the nasal cavity. The co-primary endpoints were change from baseline in symptoms, as measured by a composite score of patient-reported symptoms (including nasal congestion, facial pain or pressure, and nasal discharge) at the end of week 4, and objective change in inflammation inside the sinus cavities,
as measured by CT scans assessing the change in the average of the percentages of volume occupied by disease across the ethmoid and maxillary sinuses. The ReOpen trial program is a landmark research program because these are the first ever large, controlled trials we are aware of with any nasal medication to demonstrate significant improvement of both symptoms and inflammation inside the sinuses and to demonstrate reduction in the number of acute exacerbations.
About Chronic Sinusitis
Chronic sinusitis (CS), also called “chronic rhinosinusitis”, has been cited as the second most common chronic disease of adults in the US1. It is a serious chronic inflammatory disease affecting as many as 30 million adults in the United States and burdens the U.S. economy with over $30 billion in direct and indirect costs every year.2 CS is characterized by chronic inflammation affecting the paranasal sinuses and the nasal cavity, where the openings from the sinuses normally ventilate and drain. Chronic sinusitis is associated with symptoms that persist for at least 12 weeks, with many patients suffering for years. In addition, the condition is often associated with multiple acute exacerbations that require medical care and result in substantial use of antibiotics. In some patients, chronic sino-nasal inflammation is accompanied by development of polyps in the nasal cavities, referred to as nasal polyposis. Today, there are no FDA-approved drug treatments for the majority of chronic sinusitis patients, those who do not have polyps in the nasal cavity, although there are medications, including XHANCE, that have been approved by FDA for treatment of the smaller population of chronic rhinosinusitis patients who also have nasal polyps. The term “chronic rhinosinusitis” is sometimes used instead of “chronic sinusitis” to acknowledge that inflammation inside the sinuses is typically accompanied by inflammation in the nasal cavity.

XHANCE is a drug-device combination product that uses the Exhalation Delivery System (also referred to as the EDS) designed to deliver a topical anti-inflammatory to the high and deep regions of the nasal cavity where sinuses ventilate and drain. XHANCE is approved by the U.S. Food and Drug Administration for the treatment of chronic rhinosinusitis with nasal polyps in patients 18 years of age or older and has been studied for treatment of chronic sinusitis (notably including patients without polyps in the nasal cavity) in two phase 3 trials, ReOpen1 and ReOpen2. These trials are the first ever that we are aware of that show improvement in both symptoms and inflammation inside the sinuses, and reduction in acute exacerbations of disease, with a nasal therapy for chronic sinusitis patients, including patients with or without nasal polyps. If approved, XHANCE may be the first drug ever FDA-approved for treatment of chronic rhinosinusitis either with or without nasal polyps.
Important Safety Information
CONTRAINDICATIONS: Hypersensitivity to any ingredient in XHANCE.
WARNINGS AND PRECAUTIONS:
•Local Nasal Adverse Reactions: epistaxis, erosion, ulceration, septal perforation, Candida albicans infection, and impaired wound healing. Monitor patients periodically for signs of possible changes on the nasal mucosa. Avoid use in patients with recent nasal ulcerations, nasal surgery, or nasal trauma until healing has occurred.
•Close monitoring for glaucoma and cataracts is warranted.
•Hypersensitivity reactions (e.g., anaphylaxis, angioedema, urticaria, contact dermatitis, rash, hypotension, and bronchospasm) have been reported after administration of fluticasone propionate. Discontinue XHANCE if such reactions occur.
•Immunosuppression and Risk of Infection: potential increased susceptibility to or worsening of infections (e.g., existing tuberculosis; fungal, bacterial, viral, or parasitic infection; ocular herpes simplex). Use with caution in patients with these infections. More serious or even fatal course of chickenpox or measles can occur in susceptible patients.
•Hypercorticism and adrenal suppression may occur with very high dosages or at the regular dosage in susceptible individuals. If such changes occur, discontinue XHANCE slowly.
•Patients with major risk factors for decreased bone mineral content should be monitored and treated with established standards of care.
ADVERSE REACTIONS: The most common adverse reactions (incidence ≥ 3%) are epistaxis, nasal septal ulceration, nasopharyngitis, nasal mucosal erythema, nasal mucosal ulcerations, nasal congestion, acute sinusitis, nasal septal erythema, headache, and pharyngitis.
DRUG INTERACTIONS: Strong cytochrome P450 3A4 inhibitors (e.g., ritonavir, ketoconazole): Use not recommended. May increase risk of systemic corticosteroid effects.
USE IN SPECIFIC POPULATIONS: Hepatic impairment. Monitor patients for signs of increased drug exposure.
