Exhibit 99.1

Lyra Therapeutics Reports Fourth Quarter and Full Year 2022 Financial Results and Provides Corporate Update

-- ENLIGHTEN I Pivotal Phase 3 Trial of LYR-210 in Pre-Surgical Chronic Rhinosinusitis (CRS) on Track to Complete Enrollment in mid-2023 --

-- Data from BEACON Phase 2 Trial of LYR-220 in Post-Surgical CRS Anticipated Q4 2023 --

-- Advancing In-House Manufacturing Capabilities to Prepare for Commercial Production --

WATERTOWN, Mass., March 29, 2023 -- Lyra Therapeutics, Inc. (Nasdaq: LYRA) (“Lyra” or the “Company”), a clinical-stage biotechnology company developing innovative therapies for the localized treatment of chronic rhinosinusitis (CRS), today reported its financial results for the fourth quarter and full year ended December 31, 2022 and provided a corporate update.

“2022 was a transformative year for Lyra. We initiated three clinical trials that we believe will build on the strong clinical data we have generated to date and confirm the value of Lyra’s drug-device technology for patients living with chronic rhinosinusitis,” said Maria Palasis, Ph.D., President and CEO of Lyra. “We look forward to sharing results from the BEACON Phase 2 trial in post-surgical CRS patients in Q4 2023 as we continue to advance the ENLIGHTEN pivotal Phase 3 program of LYR-210 in pre-surgical CRS patients.”

Dr. Palasis continued, “Our recent decision to transition manufacturing in-house to optimize the quality and supply of our product positions Lyra for long-term success. We have manufactured product to enable us to resume enrollment in the second pivotal trial, ENLIGHTEN II, earlier than planned, and are now expanding our in-house capabilities to prepare for commercial-stage manufacturing.”

2022 Key Program Highlights

Initiated two pivotal Phase 3 clinical trials of LYR-210 in Chronic Rhinosinusitis (CRS) in Surgically Naïve Patients (ENLIGHTEN I and ENLIGHTEN II):
o
The ENLIGHTEN program consists of two Phase 3 clinical trials (ENLIGHTEN I and ENLIGHTEN II) to evaluate the efficacy and safety of LYR-210 for the treatment of CRS. Each trial is enrolling 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 (MF)) or control. The aim of the two pivotal trials is to support an anticipated New Drug Application to the U.S. Food and Drug Administration for LYR-210.
o
Enrollment is ongoing in ENLIGHTEN I, with enrollment completion anticipated in mid- 2023.
o
As previously announced, Lyra temporarily paused enrollment in ENLIGHTEN II to align the trial with the availability of clinical supply. The Company anticipates resuming enrollment in the ENLIGHTEN II trial in Q2 2023, ahead of the previously reported timeline of Q3 2023.

Initiated BEACON Phase 2 trial of LYR-220 in CRS patients who remain symptomatic despite having had prior sinus surgery:
o
The BEACON Phase 2 trial is a 24-week study evaluating the safety and efficacy of LYR-220 (7500µg MF) in 40 patients with CRS who remain symptomatic despite having had prior sinus surgery. Enrollment in BEACON is complete, with data expected in Q4 2023.
o
In September 2022, Lyra announced positive initial data from the Part 1, non-randomized portion of the BEACON trial, demonstrating the feasibility and tolerability of LYR-220 placement bilaterally in post-surgical CRS patients. All six patients were treated for at least six weeks and no serious or unexpected product-related adverse events were reported.
Transitioned manufacturing to in house:
o
In Q4 2022, Lyra announced the transition of manufacturing to in-house, leveraging its expertise to reliably supply product without relying on third-party manufacturers.
o
Lyra is now advancing its in-house manufacturing capabilities to prepare for commercial production.

 

Upcoming 2023 Milestones

Resume enrollment in ENLIGHTEN II Phase 3 pivotal trial of LYR-210 in Q2 2023
Complete enrollment in ENLIGHTEN I Phase 3 pivotal trial of LYR-210 in mid-2023
Report topline results from BEACON Phase 2 study of LYR-220 in Q4 2023

 

Fourth Quarter and Full Year 2022 Financial Highlights

Cash, cash equivalents and short-term investments were $97.9 million as of December 31, 2022, compared to $109.6 million as of September 30, 2022. The Company expects its cash, cash equivalents and short-term investments balance to be sufficient to fund its planned operations into mid-2024.
Research and development expenses for the fourth quarter and full year ended December 31, 2022 were $9.5 million and $38.8 million, respectively, compared to $10.3 million and $29.7 million for the same periods in 2021. The increase year over year was primarily driven by higher clinical development costs related to the Company's three ongoing clinical trials and employee-related expenses.

https://cdn.kscope.io/db04dcfbe8f56f3b0b3544d7a3501363-img93999977_0.jpg 

 

General and administrative expenses for the fourth quarter and full year ended December 31, 2022 were $4.4 million and $17.6 million, respectively, compared to $3.6 million and $14.2 million for the same periods in 2021. The increase was primarily driven by higher employee-related costs, including stock-based compensation.
The Company recorded an impairment charge of $1.3 million related to long-lived assets for the year ended December 31, 2022.
Net loss for the fourth quarter and full year ended December 31, 2022 was $14.2 million and $55.3 million, respectively, compared to $13.6 million and $43.5 million for the same periods in 2021.

About Lyra Therapeutics

Lyra Therapeutics, Inc. is a clinical-stage biotechnology company developing therapies for the localized treatment of patients with chronic rhinosinusitis (CRS). Lyra has two investigational product candidates, LYR-210 and LYR-220, 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 and LYR-220 are bioresorbable nasal implants designed to be administered in a brief, in-office procedure and are intended to deliver six months of continuous mometasone furoate drug therapy (7500µg MF) to the sinonasal passages. LYR-210 is designed for surgically naïve patients and is being evaluated in the ENLIGHTEN Phase 3 clinical program, while LYR-220, an enlarged implant, is being evaluated in the BEACON Phase 2 clinical trial in patients who have recurrent symptoms despite having had prior ethmoid sinus surgery. These two product candidates are designed to treat the estimated four million CRS patients in the United States who fail medical management each year.

These and other important factors discussed under the caption "Risk Factors" in the company's Annual Report on Form 10-K filed with the SEC on March 29, 2023 and its other filings with the SEC could cause actual results to differ materially from those indicated by the forward-looking statements made in this press release.

Missing data and data post use of rescue medication was imputed by LOCF method; 4) Minimum clinically important difference; 5) Composite score of the 4 Cardinal Symptoms of CRS (nasal blockage, facial pain/pressure, nasal discharge (anterior/posterior) and loss of smell); Durable response = patients experiencing no worsening in 4CS scores from week 24 baseline throughout the post-treatment period. Worsened response = patients experiencing a worsening in 4CS scores from week 24 baseline (at ≥1 time points in the post-treatment period) and patients who required rescue treatment. These percentages of patient responses in the post-treatment period represent trends. Analyses are not powered for statistical significance.
