Study Confirms Efficacy of Latera Absorbable Nasal Implant

Entellus Medical Inc. has announced data from its first-in-human study of the Latera absorbable nasal implant from Spirox. The 18- and 24-month data demonstrate that patients who received Latera had significant improvement in nasal obstruction symptoms with no negative cosmetic changes.
 
“These newly released data from our study have met our pre-defined criteria for success including symptom relief without negatively affecting appearance,” stated Dr. Marion San Nicolo, M.D., University Clinic of Munich, LMU and lead enroller in the study. “In addition, patients who benefitted from Latera experienced continued symptom relief after the implant had absorbed.”
 
The study was conducted at three sites in Germany and included 30 adult patients with nasal valve collapse (NVC)—one of the most frequent causes of nasal obstruction, a condition that limits airflow and makes breathing through the nose more difficult. Patients had severe or extreme symptoms as established by the validated Nasal Obstruction Symptom Evaluation (NOSE) instrument and were treated with Latera alone. A total of 56 Latera implants were placed in 30 subjects, and patients were assessed at one week and one, three, six, 12, 18, and 24 months post-procedure.
 
Key findings of the study include:

• Continuing, significant NOSE score reduction at all time points, averaging 63.4 percent, 56.2 percent, 52 percent, 52.5 percent, and 57.7 percent at three, six, 12, 18, and 24 months, respectively (p<0.001)
• No adverse change in cosmetic appearance at 24 months post procedure
• Short learning curve for physicians adopting the technology

 
“We are pleased to see continued evidence reinforcing that Latera is a safe and effective treatment option for patients with NVC, with the potential to become standard of care,” said Robert White, president and CEO of Entellus Medical. “We look forward to increasing access to Latera for ENT physicians and plastic surgeons seeking a treatment option for their nasal obstruction patients.”
 
Entellus is a medical technology company developing less invasive treatments. Spirox Inc is a wholly-owned subsidiary of Entellus. Entellus products are used for the treatment of adult and pediatric patients with chronic and recurrent sinusitis, patients with nasal airway obstruction, as well as adult patients with persistent Eustachian tube dysfunction. Entellus’s product lines including the XprESS ENT Dilation System, Latera Absorbable Nasal Implant, MiniFESS Surgical Instruments, XeroGel Nasal Dressing and FocESS Imaging & Navigation combine to enable ENT physicians to perform a broad range of procedures.
 
Latera
 is an absorbable nasal implant, designed by ENT physicians. Latera supports the nasal cartilage to address nasal valve collapse, which reduces nasal obstruction symptoms and help patients breathe better. Patients who received the implant reported satisfaction with their breathing (86 percent) and appearance (93 percent) results.ⁱ
