Company Expects Top-Line Results in Second Quarter 2022

XHANCE Reaches Important Milestone on Path to be the First FDA-Approved Drug Treatment for the Approximately 30 million Chronic Sinusitis Sufferers in the U.S.

YARDLEY, Pa, Oct. 28, 2021 (GLOBE NEWSWIRE) -- Optinose (NASDAQ: OPTN), a pharmaceutical company focused on patients treated by ear, nose and throat (ENT) and allergy specialists, today announced it has successfully completed recruitment in the second of two Phase 3b pivotal clinical trials to evaluate the safety and efficacy of XHANCE® (fluticasone propionate) nasal spray as a treatment for patients with chronic sinusitis (CS).

“Today we are announcing completion of recruitment in the second of our two pivotal CS trials,” stated Ramy Mahmoud, M.D., MPH, President and Chief Operating Officer of Optinose. “With the recruitment phase behind us, our clinical team is now focusing on successful completion of both trials and planning for topline results from the first trial in the first quarter of 2022 and from the second trial in the second quarter of 2022. We are grateful to the patients, investigators, and clinical trial site staff who are participating in this research as we work towards achieving the first-ever FDA approval of a medication for chronic sinusitis.”

“Approximately 30 million adults in the U.S. suffer from symptoms of CS and, because there are currently no FDA-approved drug treatments for the disease, we believe the new indication would greatly expand our business opportunities while offering relief to millions of CS sufferers,” said CEO Peter Miller.

About XHANCE
XHANCE is a drug-device combination product that uses an Optinose Exhalation Delivery System (EDS™) that is designed to deliver a topical anti-inflammatory medication to high and deep regions of the nasal cavity. XHANCE was approved for the treatment of nasal polyps in patients 18 years of age or older by the U.S. Food and Drug Administration in September 2017 and is currently being studied for treatment of chronic sinusitis. If successful, XHANCE may be the first FDA-approved drug product for chronic sinusitis.

Important Safety Information
