• Additional Phase 2 BEACON trial CT scan data demonstrated statistically significant improvement in sinus opacification with LYR-220 and provided radiological evidence of improvement in chronic rhinosinusitis (CRS) patients who have had prior ethmoid sinus surgery
  
• Emerging data further support the previously reported positive BEACON topline results demonstrating CRS symptom improvement
• ENLIGHTEN I pivotal Phase 3 trial of LYR-210 in CRS patients who have not had ethmoid sinus surgery is fully enrolled; topline results expected in 1H 2024

WATERTOWN, Mass., Nov. 07, 2023 (GLOBE NEWSWIRE) -- Lyra Therapeutics, Inc. (Nasdaq: LYRA) (“Lyra” or the “Company”), a clinical-stage biotechnology company developing long-acting anti-inflammatory therapies for the localized treatment of chronic rhinosinusitis (CRS), today reported its financial results for the third quarter ended September 30, 2023 and provided a corporate update.  

The Company also announced additional positive data from the BEACON Phase 2 clinical trial of LYR-220 that demonstrated statistically significant, objective improvement and sustained symptomatic improvement in CRS patients who have had prior ethmoid sinus surgery and further support the positive topline results reported in September 2023:

• Data evaluating computed tomography (CT) scans, a pre-specified secondary endpoint, demonstrated statistically significant improvement in ethmoid sinus opacification in patients who received LYR-220, compared to sham control at week 24 (p=0.035). These data provide objective radiological evidence of improvement with LYR-220 treatment.
• At End of Study, Week 28, patients receiving LYR-220 showed continued symptomatic improvement compared to sham control in both Sino-Nasal Outcome Test (SNOT-22) score (-17.6 points; p=0.007) and in a composite of the 3 cardinal symptoms of CRS (nasal obstruction, nasal discharge, facial pain/pressure; 3CS) (-1.28; p=0.063).

The Company plans to submit results of the BEACON study for presentation at an upcoming medical meeting.

“We believe Lyra is on track to develop a robust CRS product portfolio based on the continued progress of our clinical programs, including the recently reported positive results of the BEACON Phase 2 trial of LYR-220 in post-surgical CRS patients and the completion of enrollment in the ENLIGHTEN I pivotal trial of LYR-210 in pre-surgical CRS patients,” said Maria Palasis, Ph.D., President and CEO of Lyra. “Our optimism continues for LYR-220 with the additional positive CT data from the BEACON trial announced today that demonstrated objective improvement in CRS patients. We believe these findings provide additional confidence in the ongoing ENLIGHTEN pivotal Phase 3 program of LYR-210 in CRS patients who have not had ethmoid sinus surgery, for which we anticipate topline data will be available in the first half of 2024.”

LYR-210 and LYR-220 are bioresorbable nasal implants designed to deliver six months of continuous anti-inflammatory medication (mometasone furoate; MF) to the sinonasal passages for the treatment of CRS.

Program Highlights  

BEACON Phase 2 Clinical Trial of LYR-220 in CRS Patients who Have Had Prior Ethmoid Sinus Surgery

• In September 2023, Lyra announced positive topline results from the BEACON Phase 2 clinical trial of LYR-220 in adult patients with CRS, with and without polyps, who have recurrent symptoms despite prior ethmoid sinus surgery. The study met its primary safety endpoint, with no serious adverse events observed. LYR-220 demonstrated statistically significant and clinically relevant improvements in SNOT-22 (-16.8; p=0.007) scores and 3CS (-1.50; p=0.02) compared to sham control at 24 weeks, with statistically significant improvement observed as early as week 2 in SNOT-22 and at week 4 in 3CS. The most commonly reported adverse events included sinusitis, nasopharyngitis, bronchitis, and COVID-19.

The Phase 2 BEACON trial is a randomized, controlled, parallel-group study intended to evaluate the safety and placement feasibility of the LYR-220 (7500µg MF) matrix, over a 28-week period, in symptomatic CRS patients who have had prior ethmoid sinus surgery. The study consists of two parts: Part 1 was designed primarily to assess the feasibility and tolerability of two 7500µg MF matrix designs; in Part 2, 42 patients were randomized 1:1 to receive LYR-220 or sham control.

ENLIGHTEN Pivotal Program of LYR-210 in CRS Patients who have not had Ethmoid Sinus Surgery   

• In August 2023, Lyra announced completion of enrollment in the pivotal Phase 3 ENLIGHTEN I clinical trial.
• Topline results from the ENLIGHTEN I clinical trial are anticipated in the first half of 2024.  
• Enrollment is ongoing in the second pivotal Phase 3 trial, ENLIGHTEN II; enrollment completion is expected in the second half of 2024.

The ENLIGHTEN program consists of two pivotal Phase 3 clinical trials, ENLIGHTEN I and ENLIGHTEN II, to evaluate the efficacy and safety of LYR-210 for the treatment of CRS. The Company designed each trial to evaluate 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 over 24 weeks. The goal of the two pivotal trials is to support a New Drug Application to the U.S. Food and Drug Administration for LYR-210.

Third Quarter 2023 Financial Highlights

Cash, cash equivalents and short-term investments as of September 30, 2023 were $102.6 million, compared with $116.2 million at June 30, 2023. Based on our current business plan, we anticipate that our cash, cash equivalents and short-term investment balance is sufficient to fund our operating expenses and capital expenditures into the first quarter of 2025. 

Research and development expenses for the quarter ended September 30, 2023 were $12.4 million compared to $10.1 million for the same period in 2022. During the quarter ended September 30, 2023, clinical development costs increased by $2.4 million as we continued to enroll patients in our ENLIGHTEN I and ENLIGHTEN II Phase 3 clinical trials, employee related costs increased by $1.0 million, associated allocated costs increased by $0.4 million as we increased our headcount to support increased research and development activities and professional and consulting fees increased by $0.1 million. These increases were partially offset by decreased product development and manufacturing costs of $1.2 million related to bringing production efforts in house, and decreased depreciation costs of $0.4 million.    

General and administrative expenses for the quarter ended September 30, 2023 were $5.0 million compared to $5.1 million for the same period in 2022. The decrease in general and administrative expenses for the three months ended September 30, 2023 was primarily attributable to decreased employee related costs of $0.6 million, of which $0.5 million was related to stock-based compensation, and decreased allocated costs of $0.4 million, as well as the decrease in public company-related costs of $0.1 million. This decrease was partially offset by increased professional and consulting costs of $0.6 million and increased support costs of $0.4 million.

Net loss for the quarter ended September 30, 2023 was $15.7 million compared to $14.8 million for the same period in 2022.  

About Lyra Therapeutics

Lyra Therapeutics, Inc. is a clinical-stage biotechnology company developing long-acting anti- inflammatory 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 inserted in an 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 patients who have not had sinus surgery 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 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.
