YARDLEY, Pa., Aug. 11, 2022 (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 ended June 30, 2022, and provided operational updates.

"We reported confirmatory, positive topline results from ReOpen2 in June and are further encouraged by the consistency observed in key secondary and pooled results," stated CEO Peter Miller. "These data potentially support a new indication for XHANCE as a treatment for chronic sinusitis which we believe could increase the total addressable market for XHANCE by a factor of approximately ten compared to current indication. Our team plans to submit an sNDA by the end of 2022. Our current business is performing well, XHANCE net revenue increased 12% in the second quarter of 2022 compared to second quarter 2021 and increased 21% on a year-to-date basis. We changed our full year 2022 guidance for net revenue because we experienced greater than expected vacancy rates in our sales territories in recent months and greater than expected summer seasonal volume declines. However, we are optimistic about the impact that filling vacant sales territories, fall seasonal volume increases, and new clinical data showing a reduction in acute exacerbations in nasal polyp patients could have on prescriptions."

Second Quarter 2022 and Recent Highlights

ReOpen2

In June, the Company announced that the ReOpen2 clinical trial met both of its co-primary endpoints. A statistically significant improvement was demonstrated in patients with chronic sinusitis who were treated with XHANCE® (fluticasone propionate), a drug-device combination product with the proprietary Exhalation Delivery System™, in the ReOpen2 clinical trial compared to patients receiving the Exhalation Delivery System placebo as measured by both primary endpoints: first, a composite symptom score (comprising nasal congestion, facial pain or pressure, and nasal discharge) measured at week 4 and second, an objective measure of disease in the sinus cavities at week 24 (measured by average of the percentages of opacified volume (APOV) on CT scan across the ethmoid and maxillary sinuses).

"ReOpen2 was the second of two trials studying XHANCE for the treatment of patients with chronic sinusitis, a disease for which there are no FDA-approved drug treatments," said Ramy Mahmoud, MD, MPH, President of Optinose. "In ReOpen2 we found confirmatory evidence that patients with chronic sinusitis who used XHANCE improved, as measured by both a composite symptom score and as measured by the amount of inflammation in the sinuses themselves. ReOpen2 was exciting news for us and for tens of millions of people suffering from chronic sinusitis and added importantly to the growing body of evidence that may inform use of XHANCE to treat sinonasal disease."

The safety profile and tolerability of XHANCE in this trial were generally consistent with its currently labelled safety profile. Adverse events occurring at a rate of more than 3% with XHANCE and more common than in the Exhalation Delivery System placebo group were: epistaxis, COVID-19, headache, and depression.

Detailed results from this trial will be submitted for publication in a peer-reviewed journal and for presentation at future medical meetings.

Pooled Results from the ReOpen Program

In July, the Company announced selected pooled results from the ReOpen program.

To inform possible differences in response of patients previously using a standard nasal steroid spray, a pre-planned analysis of pooled data 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.

In addition, 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. Differences between active and placebo in 186 mcg or 372 mcg XHANCE treatment groups were similar and nominally statistically significant.

Finally, an analysis of pooled data found that the 372 mcg treatment group achieved a type 1 error controlled statistically significant reduction of 66% in the incidence of exacerbations compared to placebo comparator. Reductions in the number of exacerbations, ranging from 53 to 80%, were found for subgroups of chronic sinusitis patients with or without nasal polyps in the 186 mcg or 372 mcg XHANCE treatment groups in additional pre-planned exploratory analyses that were not type 1 error controlled. Exacerbations were defined as a worsening of at least one of the four cardinal symptoms of chronic sinusitis (nasal congestion/obstruction, rhinorrhea, facial pain/pressure, and loss of sense of smell) lasting at least 3 days accompanied by an escalation in medical care, such as doctor visits or antibiotic or steroid prescription.

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 nasal polyps. In ReOpen2, the second of the two trials, 222 patients were treated who had CS without 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 with any nasal medication to demonstrate significant improvement of both symptoms and inflammation inside the sinuses and to show reduction in the number of acute exacerbations.

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 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. 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 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 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. The 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 those with and 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.
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.
