Lyra Therapeutics Advances Phase 2 BEACON Clinical Trial of LYR-220 in Post-Surgical Chronic Rhinosinusitis Patients to Randomized Stage of Study

September 13, 2022

 21-point (37%) mean improvement in SNOT-22 total score at six weeks during the uncontrolled Part 1 stage of the 24-week BEACON trial

First patient dosed in the randomized, Part 2 stage of the BEACON trial

The LYR-220 program in post-surgical patients is in addition to LYR-210 which is in phase III for surgically naïve CRS patients.

WATERTOWN, Mass., Sept. 13, 2022 /PRNewswire/ -- Lyra Therapeutics, Inc. (Nasdaq: LYRA) (the Company or Lyra), a clinical-stage therapeutics company leveraging its proprietary XTreo™ platform to enable precise, sustained and local delivery of medications to the ear, nose and throat (ENT) passages and other diseased tissues, today announced that the first patients have been treated in Part 2, the randomized stage, of the Phase 2 BEACON clinical trial of LYR-220 in adult patients with chronic rhinosinusitis (CRS) who have had a prior sinus surgery. LYR-220 has been specifically designed to deliver six months of continuous anti-inflammatory medication in a controlled and consistent fashion to the sinonasal passages for the millions of CRS patients that continue to require treatment despite prior surgical treatment.  

The Phase 2 BEACON trial is a sham-controlled, parallel-group study to evaluate safety, tolerability, and pharmacokinetics of LYR-220 (7500µg MF) matrix, over a 24-week period, in symptomatic adult CRS patients who have had a prior bilateral sinus surgery. Part 1 of the BEACON trial was uncontrolled and designed primarily to assess the feasibility and tolerability of two matrix designs. In the randomized Part 2 stage, one design of LYR-220 will be compared to control in approximately 40 patients.

In the Part 1 stage, six patients received the LYR-220 matrix implant, demonstrating the feasibility and tolerability of LYR-220 placement bilaterally in this patient population.  All six patients were treated for at least six weeks and no serious or unexpected product related adverse events have been reported.  Although efficacy evaluation is not the objective during the uncontrolled Part 1 stage of the trial, there was a mean improvement of 21 points (37%) from the baseline in the 22-item Sino-nasal Outcome Test (SNOT-22) total score at 6 weeks. This is greater than twice the minimal clinically important difference of 8.9 points.

The first patient was dosed in Part 2, which is the randomized, controlled portion of the BEACON trial, evaluating the safety and efficacy of LYR-220. The Company anticipates completing enrollment for the full Phase 2 BEACON trial around year-end.

"From Part 1 of the trial, we have seen that both designs of LYR-220 can be successfully placed and have now determined the one matrix design to take forward to Part 2 of the trial.  In addition, we are encouraged by the preliminary efficacy improvements that we observed in SNOT-22 scores even at six weeks," said Richard Nieman, M.D., Chief Medical Officer of Lyra Therapeutics.

"We are excited to move forward to the randomized, Part 2 stage of the BEACON trial with LYR-220, adding to our continued progress with the Phase 3 ENLIGHTEN program for LYR-210 in surgically naïve CRS patients," said Maria Palasis, Ph.D., President and Chief Executive Officer of Lyra Therapeutics. "We believe that Lyra is well positioned to potentially be the first to offer solutions for the full spectrum of CRS patients treated by ENT physicians, and we look forward to continued progress on our path to treating patients."

About Chronic Rhinosinusitis (CRS)

CRS is a highly prevalent inflammatory disease of the paranasal sinuses which leads to debilitating symptoms and significant morbidities and is the fifth most common condition in people under 65. Cardinal symptoms include nasal obstruction and congestion, facial pain and pressure, nasal discharge, and olfactory loss. The prevalence of CRS in the U.S. is estimated to be 14 million, with 8 million treated annually using medical management including topical steroid sprays and oral steroids. Roughly half of those treated fail and seek alternative medical intervention. While ENT physicians perform approximately 400,000 surgeries annually for CRS, 65% of patients have recurrent symptoms and 100% require ongoing medical management. Additionally, many patients are surgery unwilling as the current procedures are invasive, not curative, and often require long recovery times.

About LYR-220

LYR-220 is an investigational product candidate that utilizes Lyra's proprietary XTreo™ platform to enable six months of local, intra-nasal, anti-inflammatory therapy from a single treatment for CRS in patients with post-surgical anatomy, a population which represents roughly forty percent of the four million CRS patients who fail medical management annually. LYR-220 is designed as a non-invasive alternative to repeat sinus surgery for CRS patients who have an enlarged nasal cavity due to sinus surgery but continue to require treatment to manage CRS symptoms. LYR-220 is a bioresorbable polymeric matrix designed to be administered in a brief, non-invasive, in-office procedure and is intended to deliver up to six months of continuous mometasone furoate drug therapy to the sinonasal passages.

About Lyra Therapeutics

Lyra Therapeutics, Inc. is a clinical-stage therapeutics company  leveraging its proprietary XTreo™ platform to enable precise, sustained, local delivery of medications to diseased tissues not accessible with conventional therapeutic approaches. Lyra's XTreo™ platform is comprised of a biocompatible mesh scaffold, an engineered elastomeric matrix and a versatile polymer-drug complex. The Company's current pipeline of therapeutics target tissues deep in the ear, nose and throat passages and are designed to deliver continuous drug therapy for up to six months following a single non-invasive, in-office administration. Lyra has two product candidates in late-stage development for CRS, a highly prevalent inflammatory disease of the paranasal sinuses which leads to debilitating symptoms and significant morbidities: LYR-210, for surgically naïve patients, is being evaluated in the ENLIGHTEN Phase 3 clinical program, and LYR-220, for patients who have recurrent symptoms despite surgery, is being evaluated in the BEACON Phase 2 clinical trial. These two product candidates are designed to treat the estimated four million CRS patients in the U.S. that fail medical management each year.
