Optinose Announces Additional Positive Results from ReOpen2 and Initial Results from Pooled Analyses of Both Trials in the ReOpen Program
Company previously announced positive top-line results from both ReOpen1 and ReOpen2, the landmark trials evaluating XHANCE as a treatment for chronic sinusitis
Multiple secondary endpoints from ReOpen2 indicate patients treated with XHANCE experienced improvement in symptoms and quality of life when compared to patients treated with placebo
In pooled data from ReOpen1 and ReOpen2, XHANCE demonstrated a benefit relative to placebo on CT scans in patients with chronic sinusitis without nasal polyps
YARDLEY, Pa., July 8, 2022— Optinose (NASDAQ:OPTN), a pharmaceutical company focused on patients treated by ear, nose and throat (ENT) and allergy specialists, today announced additional results from the ReOpen trial program evaluating XHANCE for treatment of patients with chronic sinusitis. XHANCE® (fluticasone propionate) nasal spray is a drug-device combination product combining its proprietary Exhalation Delivery System™ (EDS™) designed to uniquely deliver drug high and deep in nasal passages with an anti-inflammatory drug. These pre-planned secondary analyses of data from the ReOpen2 trial as well as pooled data from both ReOpen1 and ReOpen2 found that patients using XHANCE in these trials experienced a spectrum of benefits on symptoms and quality of life, as well improvement in objective measures of disease, relative to patients receiving a placebo comparator.
As previously disclosed, both co-primary endpoints in ReOpen2 showed significant improvement among patients treated with XHANCE versus placebo comparator, including combined symptom score at 4 weeks and average of percentages of opacified volume (APOV) at 24 weeks. In pre-planned, exploratory, secondary analyses of ReOpen2, patients treated with XHANCE were also found to have larger improvements than patients receiving placebo comparator at the 4-week time point on each of the four individual defining symptoms of chronic rhinosinusitis, including congestion/obstruction, rhinorrhea (thick drainage), facial pain or pressure, and loss of sense of smell. Pre-planned secondary analyses also revealed greater improvement on the sinonasal outcomes test (22 item), a commonly used measure of symptoms, quality of life, and functioning in chronic rhinosinusitis, at week 24 for patients receiving XHANCE then placebo comparator. Nominal p-values for the differences between the group of patients receiving XHANCE and the group of patients receiving placebo were less than 0.05 on each of these measures.
Many people with chronic rhinosinusitis have tried and are frustrated with standard nasal steroid sprays. To inform possible differences in response of patients previously using a standard nasal steroid spray, a pre-planned analysis of pooled data from ReOpen1 and ReOpen2 assessed symptom improvement for patients entering the trials with at least moderate symptoms despite reporting use of a standard nasal steroid spray. For this subgroup, patients receiving XHANCE improved more from baseline than patients receiving placebo comparator. Additionally, a pooled analysis was performed to assess change in CT scans, measured by APOV at week 24, for the subgroup of patients receiving XHANCE who had chronic sinusitis without nasal polyps. Compared to patients treated with placebo comparator, XHANCE treatment produced greater reduction in sinus opacification in this subgroup (-6.31% vs -1.55%, nominal p-value of 0.004). Differences between active and placebo in the groups receiving one or two sprays per nostril twice daily were similar and nominally statistically significant.
“We are pleased to see new evidence from ReOpen2 suggesting XHANCE treatment produces benefits on each of the cardinal symptoms of chronic rhinosinusitis and on a measure of quality of life. Symptom relief and quality of life represent the main treatment goals for patients with chronic rhinosinusitis and their doctors,” said Ramy Mahmoud, MD, MPH, President of Optinose. “In addition, we now have pooled data showing that the subgroup of patients receiving XHANCE in the ReOpen trials who had chronic sinusitis without nasal polyps experienced improvement on the APOV endpoint.”
The safety profile and tolerability of XHANCE in these trials were consistent with its currently labelled safety profile. In pooled data from both trials inclusive of both dose groups, adverse events occurring at a rate of more than 3% in patients receiving XHANCE that were also more common than in the group receiving the EDS-placebo were epistaxis, COVID-19, nasopharyngitis, and headache.

The global, randomized, double-blind, placebo-controlled Phase 3 ReOpen1 trial evaluated the efficacy and safety of intranasal administration of 186 and 372 mcg twice daily of OPN-375, marketed as XHANCE, in patients with chronic sinusitis (CS) with or without nasal polyps over 24 weeks. The co-primary efficacy endpoints were the change from baseline in symptoms as measured by a composite score of nasal congestion, facial pain or pressure sensation, and nasal discharge at the end of week 4, and the change from baseline to week 24 in the average of the percentages of ethmoid and maxillary sinus volume occupied by disease as measured by CT scan.
The global, randomized, double-blind, placebo-controlled Phase 3 ReOpen2 trial evaluated the efficacy and safety of one and two sprays of XHANCE (OPN-375) in each nostril twice daily, over 24 weeks in patients with chronic sinusitis (CS) who did not have 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 sensation, and nasal discharge) at the end of week 4, and objective change in inflammation inside the sinus cavities, as measured by the change in average of percentages of volume occupied by disease across the ethmoid and maxillary sinuses as measured by CT scan. The ReOpen trial program is a landmark research program because these are the first ever large, controlled trials we are aware of that show significant improvement of both symptoms and inflammation inside the sinuses with a nasal therapy.
About Chronic Sinusitis
Chronic sinusitis (CS), cited as the second most common chronic disease of adults in the US, is a serious chronic inflammatory disease that may affect as many as 30 million adults in the United States and cost the U.S. economy over $30 billion in direct and indirect costs every year. 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, those 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.

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 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 for patients either 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.
WARNINGS AND PRECAUTIONS:
•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.
