PDUFA target action date is March 16, 2024, for the Company's sNDA. If approved, the Company is prepared for launch of XHANCE for treatment of patients diagnosed with chronic sinusitis

Physicians diagnose chronic sinusitis 10 times more frequently than XHANCE’s current nasal polyps indication and there is no FDA-approved medication for these patients

Company reports fourth quarter and full year 2023 XHANCE net revenue of $19.9 million and $71.0 million

Conference call and webcast to be held today at 8:00 a.m. Eastern Time

YARDLEY, Pa., March 07, 2024 (GLOBE NEWSWIRE) -- Optinose (NASDAQ:OPTN), a pharmaceutical company focused on patients treated by ear, nose and throat (ENT) and allergy specialists, today reported financial results for the quarter and year ended December 31, 2023, and provided recent operational highlights.

"Our first strategic focus for 2023 was working to secure the first-ever approval of a medication for patients with chronic sinusitis," stated CEO Ramy Mahmoud, MD, MPH. "Our regulatory and clinical teams have been responsive and timely during FDA's review as the agency works towards a target action date of March 16. In addition, during 2023 we worked hard to prepare our organization to make the most of the new opportunity. We revised operations in a variety of ways to better support a 2024 launch while also successfully increasing the efficiency of our business, as evidenced by XHANCE net revenues and operating expenses that both beat our initial expectations for full year 2023. With the target FDA action date in a matter of days, I am confident that we are prepared, if approved, to rapidly make the product available to millions of patients in need, starting in our specialty physician audience."

Fourth Quarter 2023 and Recent Highlights

Chronic Sinusitis Supplemental New Drug Application (sNDA)
In May 2023, the Company announced that the U.S. Food and Drug Administration (FDA) accepted its sNDA for XHANCE® (fluticasone propionate) in the Exhalation Delivery System™ seeking a new indication for treatment of adults with chronic rhinosinusitis (commonly referred to as, chronic sinusitis). The assigned Prescription Drug User Fee Act (PDUFA) goal date is March 16, 2024.

Publication of ReOpen Clinical Program Results
In January 2024, the Company announced the publication of peer-reviewed data from the landmark ReOpen program evaluating the efficacy and safety of XHANCE in adult patients with chronic sinusitis in the Journal of Allergy and Clinical Immunology: In Practice. As detailed in the publication, both trials showed statistically significant improvement in symptoms, in inflammation inside the sinuses, and in the number of acute disease exacerbations that occurred in patients treated with XHANCE compared to patients receiving a vehicle combined with the Exhalation Delivery System (EDS-placebo).

Fourth Quarter and Full Year 2023 Financial Results

This decrease was primarily driven by a decrease in shipments. For the twelve-month period ended December 31, 2023, the Company reported $71.0 million in net revenue from sales of XHANCE, a decrease of 7% compared to $76.3 million during the twelve-month period ended December 31, 2022.

About XHANCE
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 sinonasal cavity, including sinuses and sinus drainage tracts 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. Results from 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.
