Lyra Therapeutics Presents New Positive Phase 2 LANTERN 6-Month Follow-Up and LYR-210 Pharmacokinetic Data, and LANTERN Manuscript Wins Award at the 67th Annual Meeting of the American Rhinologic Society

  • Approximately 50% of treated CRS patients experienced durable symptom improvement six months after treatment with LYR-210 (7500μg)
  • LYR-210 pharmacokinetics indicate a constant and steady daily dose of Mometasone Furoate is delivered to patients
  • LANTERN study manuscript wins ARS Annual Meeting 2021 Clinical Science Maurice Cottle Award

WATERTOWN, Mass., Oct. 4, 2021 /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, announced that new, positive LYR-210 data from the LANTERN 6-month post-treatment evaluation and recently completed pharmacokinetic study, were the subject of two oral presentations at the 67th Annual Meeting of the American Rhinologic Society (ARS) on October 1-2. The PK study was selected as a top clinical presentation at the meeting; additionally, the LANTERN Phase 2 manuscript won the ARS Annual Meeting 2021 Clinical Science Maurice Cottle Award.

Joanne Rimmer, MBBS, MA, FRCS (ORL-HNS), FRACS, Clinical Associate Professor and Otolaryngologist at Monash University in Melbourne, Australia, and an investigator in the LANTERN study, presented the LANTERN 6-month post-treatment outcomes, which showed continued safety and that about half of treated chronic rhinosinusitis (CRS) patients experienced a durable response six months post LYR-210 removal.

"The LANTERN 6-month post-treatment outcomes indicate a lasting treatment effect post-removal of LYR-210, while the control group showed worsening CRS symptoms from the Week 24 baseline," commented A/Prof. Rimmer. "A lack of strong rebound in CRS symptoms post-treatment and removal is very exciting, with potential long-term benefit for CRS patients. LYR-210 is a promising new treatment alternative for this chronic disease."

Randall A. Ow, MD, FACS, FARS, FAAOA, FAPCR, Otolaryngologist at Sacramento Ear, Nose & Throat, and principal investigator in the LYR-210 pharmacokinetic study, presented the PK study outcomes, which showed that Mometasone Furoate (MF) blood levels were constant over the 56 days, providing further evidence that LYR-210 delivers a consistent and steady daily dose of MF with accompanying rapid symptom relief during this time period.

"There is a need for long-acting, local CRS treatments that deliver a targeted and constant therapeutic dose to the site of the disease, while alleviating need for daily adherence," said Dr. Ow. "This release profile is exactly what I would want in an anti-inflammatory implant and the symptom improvement observed with LYR-210 is quite meaningful. LYR-210 is highly convenient to administer and remove in a routine office visit and has the potential to provide an impactful treatment option for a broad CRS patient population."

"The LANTERN follow-up and PK data presented at ARS underscore our belief in LYR-210's potential to disrupt the CRS treatment landscape for the millions of U.S. CRS patients who fail medical management each year," said Maria Palasis, PhD, President and Chief Executive Officer of Lyra Therapeutics. "We are extremely proud that the LANTERN Phase 2 manuscript was recognized with the 2021 Maurice Cottle Award, granted by ARS for the best clinical rhinologic research paper of the year. We look forward to advancing the clinical development of LYR-210, and our second candidate, LYR-220 for post-surgical CRS patients, into the Phase 3 ENLIGHTEN program and Phase 2 BEACON program, respectively, around the end of this year."

LANTERN Study and 6-Month Post-Treatment Safety Follow-up

In the Phase 2, multicenter, blinded, randomized, controlled, dose-ranging LANTERN study of LYR-210 in surgically naïve adult CRS patients who had failed previous medical management, LYR-210 was shown to be safe and well-tolerated over the 24-week treatment period. LYR-210 (7500μg) demonstrated significant, rapid, durable, dose-dependent, global symptom improvement, based on composite Cardinal Symptoms (CS) scores and Sino-Nasal Outcome Test (SNOT-22), achieving statistical significance as early as 8 weeks and out to 24 weeks compared with control.

After 24 weeks, LYR-210 drug matrices were removed, and patients then underwent a 24-week post-treatment follow-up. The main objective of the post-treatment period was to assess long-term safety post-removal. Key results include:

  • LYR-210 continued to show strong safety through 24 weeks post-treatment with no increased incidence of treatment-related AEs.
  • Approximately 50% of patients experienced a durable response post-removal of LYR-210 (7500μg), with no worsening of Cardinal Symptom scores from the Week 24 baseline, compared to approximately 90% of control patients who either experienced a worsening of Cardinal Symptom scores from the Week 24 baseline or required a rescue treatment.

LYR-210 Pharmacokinetic Study

The study was designed to characterize the early PK profile and systemic exposure of mometasone furoate (MF) of two doses (7500µg and 2500µg) of LYR-210 for up to 56 days. Plasma MF concentrations were evaluated at nine different time points throughout the study: one hour post-placement of LYR-210 (Day 1), and Days 2, 3, 7, 14, 21, 28, 42, and 56. Key results include:

  • LYR-210 was safe and well-tolerated with zero serious adverse events, and achieved 100% placement success.
  • LYR-210 delivered a constant and steady daily dose of MF over the 56 days. The steady state MF plasma concentration was 41.2pg/ml and 12.2 pg/ml over the treatment duration for 7500µg and 2500µg, respectively.
  • Approximately 20% of the drug was released from LYR-210 during the 56-day study period, supporting the established 24-week drug profile.
  • LYR-210 achieved clinically relevant improvement in SNOT-22 within 2 weeks of treatment, with 37.5% of patients reporting a normal SNOT-22 score (< 8) on Day 56.

About LYR-210 for Chronic Rhinosinusitis

LYR-210 is an investigational product candidate that utilizes Lyra's proprietary XTreoTM platform to enable six months of local, intra-nasal, anti-inflammatory therapy from a single administration for chronic rhinosinusitis (CRS). LYR-210 is designed as a non-invasive alternative to sinus surgery for the millions of CRS patients who have failed medical management. It is a bioresorbable polymeric matrix 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. In the LANTERN Phase 2 study, LYR-210 (7500µg) demonstrated rapid, clinically meaningful and durable symptom improvement as measured by the SNOT-22 score and a cardinal symptom score over six months. The LANTERN study, winner of the 2021 American Rhinology Society 2021 Maurice Cottle Award, has been published in the International Forum of Allergy & Rhinology. There are approximately 14 million patients with CRS in the US, approximately 4 million of whom fail current standard of care medical management.
