Optinose (NASDAQ:OPTN) today announced the U.S. Food and Drug Administration (FDA) has approved XHANCE® (fluticasone propionate) nasal spray for the treatment of chronic rhinosinusitis without nasal polyps in patients 18 years of age and older.
ReOpen was the first ever large placebo-controlled clinical trial program to demonstrate statistically significant reduction of symptoms in chronic sinusitis patients without nasal polyps
Clinical trial program also showed reduction in sinus inflammation and in acute exacerbations, which frequently result in use of antibiotics
XHANCE uses the proprietary Exhalation Delivery System to enable deposition of a proven steroid in target areas of inflammation deep in the nose not typically reached by standard nasal sprays
Chronic sinusitis affects approximately 30 million adults in the U.S.
YARDLEY, Pa., March 15, 2024 (GLOBE NEWSWIRE) -- 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) has approved XHANCE® (fluticasone propionate) nasal spray for the treatment of chronic rhinosinusitis without nasal polyps in patients 18 years of age and older.
Chronic sinusitis (also called “chronic rhinosinusitis” or “CRS”) is one of the most common chronic diseases, affecting approximately 30 million adults in the United States. Research shows that the disease impairs quality of life to a similar degree as other serious chronic conditions, such as chronic obstructive pulmonary disease, sciatica, or migraine. Chronic sinusitis is also one of the most common diagnoses in adult outpatient medicine. Chronic sinusitis is diagnosed in approximately 10 million outpatient visits, of which approximately 70% result in antibiotic prescriptions, and leads to more than 600,000 surgeries annually. Although there are FDA–approved medications to treat nasal polyps, including XHANCE, no medication had ever been approved for the more than two-thirds of chronic sinusitis patients who do not have nasal polyps – until today.1
“The FDA approval of XHANCE for the treatment of CRS without nasal polyps is an important milestone,” said Rick Chandra, M.D., Professor of Otolaryngology-Head and Neck Surgery, Endowed Director, Roland “Ron” Eavey, MD, SM Endowed Directorship in Leadership and Education, Service Chief, Rhinology and Skull Base Surgery, Vanderbilt University. “Until today, we have been forced to use unproven therapies to try and alleviate the symptoms that these patients suffer. While we often resort to using nasal steroid sprays in this patient population, they have never been shown to be effective in large placebo-controlled clinical studies. XHANCE, which uses the Exhalation Delivery System to enable delivery of an established topical steroid to the areas of the nasal cavity and sinuses we know to be extensively inflamed, is now proven to be effective in treating our CRS patients both with and without nasal polyps.”
“People who don’t suffer from chronic sinusitis may not appreciate how burdensome the condition can be. More than 80% of patients with chronic sinusitis report frustration with symptom relief when using a standard-delivery nasal steroid sprays, and patients commonly use multiple unproven over the counter medications in an effort to find symptom relief.” said Ramy Mahmoud, MD, MPH, CEO of Optinose. “Although chronic sinusitis is one of the most common diagnoses in outpatient physician visits, and surgery is available, there has never been a prescription medication approved by the FDA as safe and effective to treat the millions of patients without nasal polyps suffering from this debilitating disease. We are thrilled to now be able to offer new hope to these patients and believe XHANCE has the potential to become part of the standard of care for the treatment of chronic sinusitis.”
The approval was based on data from the ReOpen program evaluating XHANCE for treatment of adults with chronic sinusitis. A drug-device combination product, XHANCE uniquely combines a widely used nasal steroid with the Exhalation Delivery System™, an innovative delivery system designed to target the sites where inflammation occurs, especially difficult-to-access sinuses and sinonasal drainage tracts not typically reached by standard-delivery nasal sprays.
The safety profile and tolerability of XHANCE for patients in the ReOpen trials was generally consistent with its currently labeled safety profile. The most common adverse reactions (incidence ≥ 3%) in the ReOpen program were epistaxis, headache, and nasopharyngitis.

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 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 the treatment of chronic rhinosinusitis (with and without nasal polyps) in patients 18 years of age or older.
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 in each nostril twice daily, over 24 weeks, in patients suffering from chronic sinusitis. In ReOpen1, the first of the two trials, 332 chronic sinusitis patients either with or without concurrent nasal polyps were treated. In ReOpen2, 222 chronic sinusitis patients who did not have polyps in the nasal cavity were treated. The co-primary endpoints were change from baseline in symptoms, as measured by composite symptom score (nasal congestion, facial pain or pressure, and nasal discharge) at the end of week 4, and change in inflammation inside the sinus cavities, as measured by CT scans (change in the average of the percentages of volume occupied by disease in the ethmoid and maxillary sinuses) at week 24. The ReOpen trial program is a landmark research program that included the first ever large, placebo-controlled trials we are aware of to demonstrate that any nasal medication produces significant improvement in both symptoms and inflammation inside the sinuses for patients with chronic sinusitis, regardless of whether or not nasal polyps are present, and to show reduction in the number of acute exacerbations.1
IMPORTANT SAFETY INFORMATION
CONTRAINDICATIONS: Hypersensitivity to any ingredient in XHANCE.
WARNINGS AND PRECAUTIONS:
- 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.
ADVERSE REACTIONS:
- 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.
