YARDLEY, Pa., March 08, 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 and year ended December 31, 2021, and provided recent operational highlights.

"For the full year of 2021 versus 2020, XHANCE net revenues increased 52%, while total prescriptions and new prescriptions increased by 28% and 27%, respectively," stated CEO Peter Miller. "I believe these are outstanding results particularly in the context of a pandemic environment which has constrained both patient visits to physician offices and the ability of our territory managers to broadly meet in-person with our targeted physicians. Looking forward, I expect 2022 to be exciting time for our company as we continue to produce strong revenue growth with our current business, and we expect to complete our second clinical trial evaluating XHANCE for the treatment of chronic sinusitis. If successful, XHANCE has the potential to be the first ever drug treatment approved by the FDA for this indication which could be a game changer for both the 30 million patients suffering from symptoms of chronic sinusitis and for our company."

Fourth Quarter 2021 and Recent Highlights

Total and New XHANCE Prescriptions The number of XHANCE® (fluticasone propionate) prescriptions increased by 27% from 73,900 in the fourth quarter 2020 to 93,700 in the fourth quarter 2021. In addition, XHANCE prescriptions increased by 28% from 261,400 for the full year of 2020 to 335,600 for the full year of 2021.

The number of new prescriptions for XHANCE increased by 21% from 24,600 in the fourth quarter of 2020 to 29,900 in the fourth quarter of 2021. In addition, new prescriptions for XHANCE increased by 27% from 88,600 for the full year of 2020 to 112,700 for the full year of 2021.

ReOpen1 Clinical Trial Top-line ResultsIn March 2022, the Company announced that the ReOpen1, a landmark clinical trial in chronic sinusitis, met both of its co-primary endpoints. A statistically significant improvement was demonstrated in patients with chronic sinusitis who were treated with the XHANCE Exhalation Delivery System™ in the ReOpen1 clinical trial compared to patients receiving an 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 percent of the opacified volume on CT scan, summed across all of the ethmoid and maxillary sinuses).

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 the Exhalation Delivery System placebo were: epistaxis, nasopharyngitis, asthma, and cataract (nuclear and cortical).

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

Corporate Guidance

XHANCE Net Revenue and Average Net Revenue per PrescriptionThe Company expects XHANCE net revenues for the full year of 2022 to be at least $90 million. This includes the Company's expectation that first quarter 2022 XHANCE net revenue will decrease compared to fourth quarter 2021. The primary driver of the sequential decrease to revenue is the Company's expectation that XHANCE average net revenue per prescription for the first quarter of 2022 will decrease, due to typical early-year effects on price and volume related to patient insurance that the Company believes are common for chronic treatments that derive a significant proportion of total prescriptions from refills. The Company expects XHANCE average net revenue per prescription to exceed $210 for full year 2022.

Operating ExpensesThe Company expects total GAAP operating expenses (selling, general & administrative expenses and research & development expenses) for 2021 to be in the range of $135 to $140 million, of which the Company expects stock-based compensation to be approximately $10 million.

Chronic Sinusitis Clinical TrialsThe Company expects top-line results from ReOpen2, the second its two clinical trials evaluating XHANCE as a potential treatment for chronic sinusitis, in the second quarter of 2022.
