Analysis Also Confirms Treatment with PROPEL Provides Improved Patient Outcomes
Intersect ENT, Inc. XENT, a company dedicated to transforming care for patients with ear, nose and throat conditions, today announced the results of a United Kingdom-based independent analysis measuring costs and patient outcomes of the PROPEL steroid releasing sinus implant compared to a non-drug-eluting spacer following endoscopic sinus surgery for patients with chronic sinusitis. The study demonstrated that the use of PROPEL following surgery resulted in fewer post-operative complications and could save the National Health System (NHS) approximately £160,692 over a six-month time horizon.
The study, conducted by Device Access UK, showed that use of PROPEL following sinus surgery is a more effective intervention (than non-drug-eluting spacers) causing fewer occurrences of symptom recurrence or surgical failure when compared to spacers alone. Through localized, gradual delivery of mometasone furoate over 30 days, PROPEL maintained patency and provided drug delivery without the need for patient interaction, minimizing reliance on patient compliance. While the cost of initial treatment with PROPEL was greater, a reduction in the number of post-operative complications resulted in an overall cost savings.
Chronic rhinosinusitis is one of the most common chronic health problems among adults in the United Kingdom resulting in approximately 75,000 annual physician visits.1 Of those with chronic rhinosinusitis, approximately 15% undergo sinus surgery yearly after failing medical treatment.2 Quality of life scores of patients with chronic rhinosinusitis are significantly lower than in other common chronic diseases, such as congestive heart failure, angina, chronic obstructive pulmonary disease, and back pain.3 Chronic rhinosinusitis symptoms may include drainage of excess mucus, nasal blockage or congestion, difficulty breathing, pain and tenderness around the eyes, cheeks, nose and forehead, a reduced sense of smell and taste, and fatigue and irritability.4
"The data analysis provides promising insight into the potential cost savings and improved patient outcomes associated with the use of the PROPEL drug eluting sinus implant following endoscopic sinus surgery," said study author Dr. Mehdi Javanbakht, Head of Health Economics Unit at Device Access UK Ltd, University of Southampton Science Park. "Post-operative treatment regimens are critical to surgery success, but current options fall short in minimizing post-operative complications. PROPEL offers patients with chronic rhinosinusitis a safe and effective option that reduces the likelihood of unpleasant complications, thereby decreasing the need for post-operative interventions."
The PROPEL family of drug-eluting stents expand to prop open the sinuses after sinus surgery and gradually deliver mometasone furoate, an anti-inflammatory medicine, directly to the sinus lining before dissolving. PROPEL and PROPEL Mini received CE Mark in July 2014.
"More than 350,000 patients have been treated with PROPEL products globally, demonstrating acceptance among patients, their physicians and payors in the United States," said Thomas A. West, President and Chief Executive Officer at Intersect ENT. "We are pleased that this independent analysis adds to the robust clinical data supporting the effectiveness of the PROPEL family of sinus implants as well as highlighting the potential economic and quality of life benefits associated with PROPEL products."
