Intersect ENT Announces FDA Approval of Newest Steroid Releasing Implant, PROPEL® Contour, for Use in Treating the Frontal and Maxillary Sinuses

Approval Broadens Patient Population for Localized Drug Delivery

MENLO PARK, Calif. — (BUSINESS WIRE) — Intersect ENT, Inc. (Nasdaq:XENT), a company dedicated to transforming care for patients with ear, nose and throat conditions, today announced that the company has received approval from the U.S. Food and Drug Administration (FDA) for its PROPEL® Contour steroid releasing sinus implant. PROPEL Contour features an innovative hourglass design that facilitates treatment of patients with chronic sinusitis in the frontal (behind the forehead) and maxillary (behind the cheeks) sinuses.

With this approval, Intersect ENT’s PROPEL family of steroid releasing implants allows for treatment of patients undergoing ethmoid, frontal or maxillary surgeries, which represent the majority of procedures for the treatment of chronic sinusitis.

PROPEL Contour, the latest in the PROPEL family of steroid releasing sinus implants, is specifically designed to conform to the sinus ostia (openings), focusing drug delivery and mechanical support where it is needed in order to maximize sinus surgery outcomes. The implant features a low-profile flexible delivery system to make it easier to access tight areas of the sinus anatomy.

“The approval of PROPEL Contour adds a third product under the PROPEL umbrella, expanding our offering of steroid releasing implants to improve surgical outcomes,” said Lisa Earnhardt, president and CEO of Intersect ENT. “With its strong clinical evidence, we expect that PROPEL Contour will extend adoption of our sinus implants both in the operating room as well as in the office, and that offering physicians a wide range of products to customize treatment based on their patients’ disease and anatomy will ultimately lead to broader overall usage.”

Positive data from the PROPEL Contour cohort of the PROGRESS study, a prospective, randomized, blinded, multi-center trial of 80 patients designed to assess the safety and efficacy of the implant when placed in the frontal sinuses following surgery, supported the approval. The study met its primary efficacy endpoint, demonstrating a statistically significant 65 percent relative reduction in the need for post-operative interventions, such as the need for additional surgical procedures or the need for oral steroid prescription, compared to surgery alone.

“The introduction of PROPEL steroid releasing implants has led to meaningful benefits in how we as surgeons manage our patients, especially by reducing our reliance on oral steroids to prevent post-operative complications,” said Robert Weiss, M.D., director and founder of CT ENT Sinus and Allergy Hearing and Balance in Norwalk, Conn., and one of the PROGRESS study investigators. “With PROPEL Contour, we are able to offer those benefits to a significant range of our chronic sinusitis patients, regardless of their unique anatomy, and to do so with the comfort of the same rigorous clinical evidence for which the PROPEL family of products is known. With this base of solid evidence pointing to a clear benefit, there are strong reasons to include PROPEL as part of standard clinical practice.”

2017 Outlook

The company expects to launch PROPEL Contour broadly in the second quarter of 2017 and maintains its previously stated 2017 revenue guidance of $87-$89 million.

Management will discuss this outlook, along with recent financial results and business updates, on a conference call scheduled for February 28, 2017 at 4:30 p.m. ET.

About PROPEL® Steroid Releasing Sinus Implants

Intersect ENT’s PROPEL products are the first and only dissolvable steroid releasing sinus implants approved by the FDA. Clinically proven to improve outcomes for chronic sinusitis patients following sinus surgery, PROPEL sinus implants mechanically prop open the sinuses and release mometasone furoate, an advanced corticosteroid with anti-inflammatory properties, directly into the sinus lining then dissolve. PROPEL’s safety and effectiveness is supported by Level 1-A clinical evidence from multiple clinical trials, which demonstrates that PROPEL implants reduce inflammation and scarring after surgery, thereby lessening the need for post-operative oral steroids and repeat surgical interventions. More than 150,000 patients have been treated with PROPEL products to date. PROPEL is indicated for the ethmoid sinus; PROPEL Mini is indicted for the ethmoid and frontal sinuses; PROPEL Contour is indicated for the frontal and maxillary sinuses.

About PROPEL® Contour Steroid Releasing Sinus Implant

PROPEL Contour represents the newest addition to the PROPEL family of dissolvable steroid releasing implants, clinically proven to improve results of sinus surgery. With its unique hourglass shape, PROPEL Contour conforms to sinus ostia, propping sinuses open while delivering anti-inflammatory medication when placed in the operating room or sinus dilation in the physician’s office. PROPEL Contour’s low-profile design allows for placement in smaller sinus openings, like those of the frontal and maxillary sinuses, expanding the applicable patient population for steroid releasing implants.
