$50 Million from Recent Financing Extends Expected Cash Runway Beyond the Expected PDUFA Action Date for XHANCE as a Treatment for Chronic Sinusitis

Revised Note Purchase Agreement Extends Start of Amortization to September 2025

YARDLEY, Pa., Nov. 30, 2022 (GLOBE NEWSWIRE) -- Optinose (NASDAQ:OPTN), a pharmaceutical company focused on patients treated by ear, nose and throat (ENT) and allergy specialists, today provided corporate updates and announced that CEO Peter Miller will participate in a fireside chat at the 34th Annual Piper Sandler Healthcare Conference on December 1, 2022.

“The addition of cash from the recent financing and the amendment of our note purchase agreement with Pharmakon enable our organization to focus on XHANCE growth and the submission of a supplemental NDA in early 2023,” stated CEO Peter Miller. "We believe chronic sinusitis is an enormous opportunity relative to our current business with up to 10 times the number of diagnosed patients versus our current nasal polyps indication – many of whom are treated by the same physicians we call on today. We believe a first-ever approval in chronic sinusitis would be a significant advancement in care for patients and represents a valuable opportunity for our specialty business and a potential partner in primary care."


Corporate Updates
On November 23, 2022, the Company’s previously announced common stock and warrant financing closed resulting in approximately $50.0 million of gross proceeds to the Company, prior to deducting underwriting discounts and commissions and expenses payable by the Company.  The Company expects that its current cash and cash equivalents (inclusive of the proceeds from the financing) will be sufficient to fund its operations and debt service obligations through the expected PDUFA action date for XHANCE as a treatment for chronic sinusitis in the fourth quarter of 2023.

Concurrent with the financing, the Company amended and restated its note purchase agreement with Pharmakon. The amended and restated agreement extends the interest only period from September 30, 2023 to September 30, 2025, extends the maturity date from September 30, 2024 to June 30, 2027, modifies the financial covenant requiring the Company to achieve minimum trailing twelve-month consolidated XHANCE net product sales and royalties (including eliminating such covenant until the twelve-month period ending March 31, 2024), and modifies certain other terms.

For additional details regarding the amended and restated Note Purchase Agreement, please review the Company’s recent SEC filings on Form 8-K. These filings are available on the Investors page of the Optinose website as well as at the SEC’s website

About the ReOpen Program
The ReOpen program comprises 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 patients were treated who had CS with or without concurrent nasal polyps. In ReOpen2, the second of the two trials, 222 patients were treated who had CS, none of whom also had nasal polyps. 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) through week 4, and change in inflammation inside the sinus cavities, as measured by the change in the average of percentages of volume occupied by disease across the ethmoid and maxillary sinuses as measured by CT scan.

About Chronic Sinusitis
Chronic sinusitis (CS), cited as the second most common chronic disease of adults in the US1, is a serious chronic inflammatory disease affecting as many as 30 million adults in the United States and costing the U.S. economy 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 most patients suffering for many years. In addition, the condition is often associated with multiple acute exacerbations that 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 who do not have nasal polyps, though there are medications, including XHANCE, approved by FDA for treatment of nasal polyps. The term “chronic rhinosinusitis” is also often used as an umbrella term in medical literature to refer to patients with chronic inflammatory disease in the nose and sinuses, with or without nasal polyps.

About Optinose
Optinose is a specialty pharmaceutical company focused on serving the needs of patients cared for by ear, nose and throat (ENT) and allergy specialists. To learn more, please visit or follow us on Twitter and LinkedIn.

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 nasal polyps in patients 18 years of age or older and has been studied for treatment of chronic sinusitis in two phase 3 trials, ReOpen1 and ReOpen2. Top-line 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 sinusitis either with or without nasal polyps.

Important Safety Information

CONTRAINDICATIONS: Hypersensitivity to any ingredient in XHANCE.


  • Local Nasal Effects: 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.

  • 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: 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.
