Item 5.03

Amendment to Articles of Incorporation or Bylaws; Change in Fiscal Year.

On May 27, 2025, Lyra Therapeutics, Inc. (the “Company”) filed a Certificate of Amendment to its Restated Certificate of Incorporation, as amended (the “Charter Amendment”) with the Secretary of State of the State of Delaware to effect a 1-for-50 reverse stock split (the “Reverse Stock Split”) of the Company’s common stock, par value $0.001 per share (the “Common Stock”), effective May 27, 2025 at 5:00 p.m., Eastern Time (the “Effective Time”) and the Company’s shares of Common Stock began trading on a split-adjusted basis on The Nasdaq Capital Market at the commencement of trading on May 28, 2025, under the Company’s existing trading symbol “LYRA”. The new CUSIP number for the Common Stock following the Reverse Stock Split is 55234L 204.

As previously reported, the Reverse Stock Split was approved by the Company’s stockholders at the Company’s annual meeting of stockholders held on May 14, 2025, at a ratio ranging from any whole number between 1-for-10 and 1-for-50, as determined by the Company’s board of directors (the “Board”) in its discretion. On May 14, 2025, the Board approved a ratio of 1-for-50 for the Reverse Stock Split and abandoned all other amendments.

The Charter Amendment provides that at the Effective Time, every 50 shares of the Company’s issued and outstanding shares of Common Stock immediately prior to the Effective Time, will be automatically converted, without any action on the part of the holder thereof, into one share of Common Stock. The number of authorized shares of Common Stock and the par value of each share of Common Stock remain unchanged. No fractional shares will be issued as a result of the Reverse Stock Split. Stockholders who otherwise would be entitled to receive a fractional share in connection with the Reverse Stock Split will receive a cash payment in lieu thereof.

The foregoing description is qualified in its entirety by the Charter Amendment, a copy of which is filed as Exhibit 3.1 to this Current Report on Form 8-K (the “Current Report”) and is incorporated herein by reference.

Exhibit 99.1

Lyra Therapeutics Reports Positive Results from the ENLIGHTEN 2 Phase 3 Trial of LYR-210 Achieving Statistically Significant Results for Primary and Key Secondary Endpoints in the Treatment of Chronic Rhinosinusitis (CRS)

 

   

ENLIGHTEN 2 trial met primary endpoint with LYR-210 demonstrating statistically significant improvement in the composite of the three cardinal symptoms (3CS) of CRS at 24 weeks (p=0.0078)

 

   

ENLIGHTEN 2 trial also showed statistically significant improvement in key secondary endpoints in the full population of 3CS at 24 weeks (p=0.0209) and SNOT-22 score at 24 weeks (p=0.0101)

 

   

Additionally, in pooled data from ENLIGHTEN 2 and ENLIGHTEN 1 trials in 64 CRS patients with nasal polyps, LYR-210 demonstrated a consistent positive trend over 24 weeks in multiple key efficacy endpoints

 

   

Lyra plans to review the totality of the dataset from the ENLIGHTEN trials to evaluate next steps for pursuing an indication in non-polyp patients, as well as to continue development of LYR-210 in patients with nasal polyps

 

   

Conference call to discuss trial results today at 8:30 a.m. ET

WATERTOWN, Mass., June 2, 2025 – Lyra Therapeutics, Inc. (Nasdaq: LYRA) (“Lyra” or the “Company”), a clinical-stage biotechnology company developing long-acting, anti-inflammatory sinonasal implants for the treatment of chronic rhinosinusitis (CRS), today announced positive results from the ENLIGHTEN 2 Phase 3 clinical trial of LYR-210 in adult patients with CRS. The ENLIGHTEN 2 trial met its primary endpoint, with LYR-210 demonstrating statistically significant improvement compared to sham control in a composite of the three cardinal symptoms (3CS) of CRS (nasal obstruction, nasal discharge, facial pain/pressure) at week 24 (-1.13; p=0.0078) in patients without nasal polyps.

The ENLIGHTEN 2 trial also met the key secondary endpoints of 3CS at 24 weeks in the full population (i.e., patients with and without nasal polyps) (-0.90; p=0.0209) and in the clinically-validated SNOT-22 score at 24 weeks (-8.7; p=0.0101), with symptom improvement observed as early as week 4. Consistent with previous studies, LYR-210 was well-tolerated, with a safety profile similar to sham control.

The ENLIGHTEN program consists of two Phase 3 clinical trials, ENLIGHTEN 1 and ENLIGHTEN 2, to evaluate the efficacy and safety of LYR-210 for the treatment of CRS. While the ENLIGHTEN 2 trial met its primary endpoint and key secondary endpoints, the ENLIGHTEN 1 trial did not meet the primary endpoint or secondary endpoints, as previously reported in May 2024. Each ENLIGHTEN trial has enrolled approximately 180 CRS patients who have failed medical management and have not had prior ethmoid sinus surgery, randomized 2:1 to either LYR-210 (7500µg mometasone furoate) or sham control. The 24-week endpoints in the ENLIGHTEN trials assess LYR-210’s long-acting therapeutic effect as a bioresorbable nasal implant designed to deliver six months of continuous anti-inflammatory medication to the sinonasal passages.


Results for Primary and Key Secondary Endpoints from ENLIGHTEN 2 Phase 3 Trial

Patients reported LYR-210 significantly improved important outcome measures on primary and key secondary endpoints:

 

   

Statistically significant improvement compared to sham control in a composite of the 3CS of CRS at week 24 (-1.13; p=0.0078) in patients without nasal polyps.

 

   

Statistically significant improvement in 3CS with LYR-210 compared to sham control at week 24 (-0.90; p=0.0209) in the full population (i.e., patients with and without nasal polyps)

 

   

Statistically significant improvements in Sino-Nasal Outcome Test (SNOT-22) score with LYR-210 compared to sham control at week 24 (-8.7; p=0.0101)

 

   

Improvements in SNOT-22 were observed as early as week 4 with LYR-210 compared to sham control (-6.4; p=0.0456)

 

   

Improvements in SNOT-22 were sustained throughout the trial and were clinically meaningful, with more than twice the minimal clinically important difference observed at week 24 compared to baseline in the LYR-210 group (-22.4 points)

 

   

Data evaluating computed tomography (CT) scans demonstrated numerical improvement in ethmoid sinus opacification in patients who received LYR-210, compared to sham control at week 20 (-2.15; p=0.1809). These data provide objective radiological evidence of improvement with LYR-210 treatment.

 

   

LYR-210 patients showed no difference from sham patients in use of corticosteroid rescue medication; however, the LYR-210 patients had fewer endoscopic sinus surgeries compared to sham control.

LYR-210 was well tolerated, with no product-related serious adverse events in the ENLIGHTEN 2 trial. The most commonly reported adverse events included epistaxis, upper respiratory tract infection, chronic sinusitis, acute sinusitis, nasopharyngitis, COVID-19, and headache.

Results for CRS Patents with Nasal Polyps in Pooled Analysis from ENLIGHTEN 1 and ENLIGHTEN 2

Additionally, Lyra conducted a pooled data analysis of a total of 64 CRS patients with small nasal polyps (grade 1) from the ENLIGHTEN 1 and ENLIGHTEN 2 trials. The data demonstrated a consistent positive trend compared to sham control over 24 weeks in multiple endpoints:

 

   

Improvement in 3CS with LYR-210 compared to sham control at week 24 (-1.13; p=0.0837), starting as early as week 4.

 

   

Improvement in SNOT-22 score with LYR-210 compared to sham control at week 24 (-8.7; p=0.1331), starting as early as week 4.

 

   

Improvements in percent ethmoid opacification with LYR-210 compared to sham control at week 20 (-6.07; p=0.1127).

 

   

Improvements in nasal congestion score (NCS) with LYR-210 compared to sham control at week 24 for patients with moderate to severe NCS at baseline (-0.33; p=0.2159), starting as early as week 4.

 

   

Improvements in nasal polyp score with LYR-210 compared to sham control at week 24 (-0.16; p=0.3494).


“We are thrilled to announce these positive results from our ENLIGHTEN 2 trial. We believe this has the potential to provide a path to advance LYR-210 to treat CRS, offering six months of therapy in a single administration for millions of patients who do not respond to standard CRS medical management. We will continue to review the totality of the dataset from the ENLIGHTEN trials to optimize our regulatory strategy,” said Maria Palasis, Ph.D., President and CEO, Lyra Therapeutics. “Given these data we reported today, we plan to align with the FDA on a path forward for an NDA submission in patients without nasal polyps. As planned, we also analyzed the pooled data from ENLIGHTEN 2 and ENLIGHTEN 1 trials to treat CRS patients with nasal polyps, and we believe this positive data positions us to proceed with a development plan in patients with nasal polyps, based on our alignment in December 2024 with FDA on endpoints, inclusion criteria, patient population, background therapy, and assessments. Looking further ahead, we envision LYR-210 achieving its potential to benefit both non-polyp and polyp patients, positioning us to become a leader in CRS and validating our platform for future ENT indications.”

“The positive results seen in the ENLIGHTEN 2 study are impressive and represent what could be a promising new treatment approach for the many CRS patients that I see every day in my practice who are underserved by limited therapies.,” said Zachary Soler, M.D., MSc, Professor in the Department of Otolaryngology-Head and Neck Surgery at the Medical University of South Carolina and coordinating Lead Investigator for the ENLIGHTEN 2 trial. “The more than 20-point improvement from baseline in SNOT-22 score after LYR-210 treatment represents a clinically meaningful improvement in patient symptoms.”

“These positive results represent a significant milestone in advancing an innovative treatment to CRS patients who suffer from this chronic condition. It’s a proud moment for us and a testament to the dedication of this team and our investigators in the development of this novel therapy.”, said Harlan Waksal, M.D., Executive Chairman, Lyra Therapeutics.

Results from the ENLIGHTEN 2 trial of LYR-210 are planned to be presented at the 71st Annual Meeting of the American Rhinologic Society, October 2025.
