Intersect ENT Announces PDUFA Date For Office-Based SINUVA Steroid Releasing Sinus Implant

MENLO PARK, Calif.--(BUSINESS WIRE)--Intersect ENT, Inc. (NASDAQ:XENT), a company seeking to improve the quality of life for patients with ear, nose and throat conditions, today announced that the U.S. Food and Drug Administration (FDA) has accepted the New Drug Application (NDA) for the company’s investigational SINUVA™ Steroid Releasing Sinus Implant and set a PDUFA target action date of January 7, 2018.

The SINUVA implant, previously known as the RESOLVE product, is placed during a routine physician office visit. The implant is designed to provide a less invasive treatment option for patients with recurrent ethmoid sinus obstruction, including polyps, that might otherwise warrant a repeat surgical procedure. More than 635,000 Americans are potential candidates for the SINUVA implant – an underserved population, as current treatment relies on high-dose oral steroids and repeat surgery.

“The SINUVA implant offers the potential to provide a less invasive and more cost-effective solution, performed easily in the doctor’s office, for patients suffering from persistent chronic sinusitis,” said Lisa Earnhardt, president and CEO of Intersect ENT. “We are excited that FDA’s filing of this NDA advances us a step closer to bringing this important innovation to ENT physicians and their patients.”

SINUVA, Intersect ENT’s fourth steroid releasing implant, was evaluated in four clinical studies to assess the safety and effectiveness of the product. The randomized, blinded, multi-center phase III RESOLVE II pivotal trial evaluated 300 adult chronic sinusitis patients, all of whom were indicated for revision sinus surgery at study entry due to recurrent symptoms and obstructive inflammation. Patients were randomized to one of two groups: a treatment group consisting of bilateral SINUVA implant placement in the office, or a control group consisting of a sham procedure; both groups continued to receive standard treatments such as topical nasal steroid sprays.

The trial met both co-primary efficacy endpoints, demonstrating a statistically significant reduction in nasal congestion and polyp burden. Secondary endpoints achieving statistical significance through day 90 included a reduction in the proportion of patients still indicated for repeat sinus surgery, reduction in ethmoid sinus obstruction, and improvements in both nasal obstruction symptoms and sense of smell.

About SINUVA Steroid Releasing Sinus Implant

The investigational SINUVA Steroid Releasing Sinus Implant is designed to be placed during a routine physician office visit to provide a less invasive treatment option for chronic sinusitis patients with recurrent sinus obstruction that would otherwise warrant revision surgery. The implant releases mometasone furoate to the ethmoid sinus lining to target inflammation directly. It was designed with greater radial strength than Intersect ENT’s PROPEL products in order to dilate obstructed sinuses and releases steroid over a longer period of time to reduce inflammation. SINUVA has not been approved by the FDA and is available for investigational use only.
