Lyra Therapeutics Announces Initiation of LYR-210 Pivotal Phase 3 ENLIGHTEN Program in Surgically Naïve Chronic Rhinosinusitis Patients

January 24, 2022
Company also announces initiation of BEACON clinical study of LYR-220 in previously operated chronic rhinosinusitis patients
LYR-210 and LYR-220 are designed to complement each other in addressing the broad spectrum of CRS patients treated by ENT Physicians

WATERTOWN, Mass., Jan. 24, 2022 /PRNewswire/ -- Lyra Therapeutics, Inc. (Nasdaq: 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 the initiation of the Phase 3 ENLIGHTEN I clinical trial of LYR-210 in adult, surgically naïve chronic rhinosinusitis (CRS) patients, with trial sites open for enrollment. LYR-210 is designed to be administered in a brief, non-invasive, in-office procedure and deliver up to six months of continuous anti-inflammatory medication to the sinonasal passages.

"LYR-210 is the first product candidate designed to provide six months of continuous therapy with a single treatment and represents a significant opportunity to introduce a new standard of care to the millions of CRS patients suffering with the disease and seeking a non-surgical treatment that provides significant symptom relief," said Maria Palasis, PhD, President and Chief Executive Officer of Lyra Therapeutics. "Following the positive results achieved in the LANTERN Phase 2 study of LYR-210 demonstrating rapid, durable, and clinically meaningful improvement, we look forward to advancing our Phase 3 ENLIGHTEN pivotal program with the initiation of ENLIGHTEN I, followed by initiation of ENLIGHTEN II, the second Phase 3 study, within the first half of this year."

ENLIGHTEN I is a Phase 3 multicenter, randomized, controlled trial to evaluate the efficacy and safety of LYR-210 compared to control. The trial will enroll approximately 180 CRS patients who have failed medical management and have not had a prior sinus surgery, randomized 2:1 to receive either LYR-210 (7500µg MF) or control. The primary endpoint of the trial is the change from baseline in a composite score of three cardinal symptoms (3CS) of CRS (i.e., nasal blockage, nasal discharge, and facial pain) at week 24. Enrollment is anticipated to be completed in the first half of 2023. After the 24-week treatment duration, control patients in ENLIGHTEN I will be eligible to crossover into treatment as part of an extension study that will also include repeat administration with LYR-210 in previously treated patients. ENLIGHTEN I is the first of two pivotal trials the company will be conducting to support the NDA for LYR-210.

For the Company's second product candidate, LYR-220 for the treatment of adult patients with CRS who have had a prior surgery for their CRS symptoms, the BEACON Phase 2 trial has been initiated. The BEACON trial is a controlled, randomized, parallel-group study to evaluate safety, tolerability, pharmacokinetics, and efficacy comparing 2 designs of LYR-220 to control over a 24-week period in approximately 70 symptomatic adult CRS subjects who have had a prior bilateral sinus surgery. Enrollment is anticipated to be completed around the end of 2022.

"As a practicing rhinologist, I am very optimistic that these product candidates will provide meaningful improvement for the millions of CRS sufferers who currently have no approved therapy and am encouraged to see the forward progress of these product candidates through clinical development. I believe these innovative treatments have the potential to transform the current treatment paradigm for the broad spectrum of CRS patients who have failed first line medical management," said Robert Kern, MD, Chief Medical Officer of Lyra Therapeutics.  

About LYR-210 & LYR-220

LYR-210 and LYR-220 are investigational product candidates that utilize Lyra's proprietary XTreoTM platform to enable six months of local, intra-nasal, anti-inflammatory therapy from a single treatment for chronic rhinosinusitis (CRS). Both product candidates are bioresorbable polymeric matrices designed to be administered in a brief, non-invasive, in-office procedure and are intended to deliver up to six months of continuous mometasone furoate drug therapy to the sinonasal passages as a non-invasive alternative to sinus surgery. LYR-210 is designed for surgically naïve patients, while LYR-220, an enlarged matrix, is intended for use in patients with post-surgical anatomy. Together, the two products are designed to address the four million CRS patients who fail medical management annually. In the LANTERN Phase 2 study, LYR-210 (7500 µg) demonstrated rapid, clinically meaningful and durable symptom improvement in CRS three cardinal symptoms (3CS) over six months. A pharmacokinetic (PK) study showed that Mometasone Furoate (MF) blood levels were constant over the 56 days, confirming that LYR-210 delivers a steady daily dose of MF with accompanying rapid symptom relief during this time period. Clinical data from LYR-210 trials may be included in LYR-220's regulatory submission. There are approximately 14 million patients with CRS in the US, with no approved treatments for roughly 90% of the CRS population.
