YARDLEY, Pa., May 09, 2024 (GLOBE NEWSWIRE) -- Optinose (NASDAQ:OPTN), a pharmaceutical company focused on patients treated by ear, nose and throat (ENT) and allergy specialists, today announced that it has entered into agreements for the sale of approximately $55 million of its common stock and pre-funded common stock warrants to a group of existing and new institutional investors in a registered direct offering.

In the registered direct offering, the Company is selling 31,800,000 shares of its common stock at a price of $1.00 per share, representing the average closing price of the Company’s common stock on the Nasdaq Global Select Market for the five trading days immediately preceding the signing of the binding agreement prior to market close on May 8, 2024. In addition, the Company is selling to certain investors pre-funded warrants to purchase up to an aggregate of 23,700,000 shares of its common stock at a price of $0.999 per each pre-funded warrant, which represents the per share offering price for the common stock less the $0.001 per share exercise price for each such pre-funded warrant. The gross proceeds from the offering are expected to be approximately $55 million, before deducting estimated offering expenses. The registered direct offering is expected to close on or about May 10, 2024, subject to the satisfaction of customary closing conditions.

The financing is being led by Nantahala Capital and the D. E. Shaw group with participation from multiple other new and existing healthcare focused investors.

“We appreciate the support of this group of new and existing investors,” said Ramy Mahmoud, MD, MPH, CEO of Optinose. “The landmark efficacy evidence from two controlled trials, followed by the first-ever FDA approval of XHANCE as a prescription treatment for chronic rhinosinusitis without nasal polyps is a strong foundation for pursuing future growth opportunities. We expect the post-offering cash and cash equivalents of approximately $100 million to fund operations and debt service obligations through 2025. With a strengthened financial footing, our team looks forward to helping millions of patients suffering from chronic sinusitis by making the first effective prescription treatment broadly available. Right now, our launch is focused on a specialty prescriber audience, and we expect XHANCE net revenues to be between $85 to $95 million for full year 2024,” he concluded.

About Optinose
Optinose is a global specialty pharmaceutical company focused on serving the needs of patients cared for by ear, nose and throat (ENT) and allergy specialists.

XHANCE is a drug-device combination product that uses the Exhalation Delivery System™ (also referred to as the EDS®) designed to deliver a topical steroid 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 both the treatment of chronic rhinosinusitis without nasal polyps (also called chronic sinusitis) and chronic rhinosinusitis with nasal polyps (also called nasal polyps) in patients 18 years of age or older.

CONTRAINDICATIONS: Hypersensitivity to any ingredient in XHANCE.

  • Local nasal adverse reactions, including epistaxis, erosion, ulceration, septal perforation, Candida albicans infection, and impaired wound healing, can occur. 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.
  • Glaucoma and cataracts may occur with long-term use. Consider referral to an ophthalmologist in patients who develop ocular symptoms or use XHANCE long-term.
  • 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 infections can occur, including 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.
  • Assess for decrease in bone mineral density initially and periodically thereafter.


  • Chronic rhinosinusitis without nasal polyps: The most common adverse reactions (incidence ≥3%) are epistaxis, headache, and nasopharyngitis.
  • Chronic rhinosinusitis with nasal polyps: 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.
