News Release

– Primary focus continues to be on upcoming results from ENLIGHTEN 1 Phase 3 extension study in 4Q 2024 and ENLIGHTEN 2 pivotal Phase 3 trial in CRS patients in 1H 2025, as planned –

– In parallel, the company continues to analyze data from ENLIGHTEN 1; further analysis of the ENLIGHTEN 1 data has revealed that LYR-210 demonstrated improvement over control in symptomatic endpoints in the CRS patient cohort with nasal polyps –

WATERTOWN, Mass., Aug. 14, 2024 (GLOBE NEWSWIRE) --  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 reported its financial results for the second quarter ended June 30, 2024 and provided a corporate update.  

“While we clearly recognize the disappointment of not meeting the primary endpoint in the previously-announced ENLIGHTEN 1 Phase 3 trial, our potential pathway to approval for LYR-210 in CRS without nasal polyps can only be determined once we unblind and analyze the full data set from the ENLIGHTEN pivotal program,” said Maria Palasis, Ph.D., President and CEO of Lyra Therapeutics. “Today we are disclosing that our further analysis of the ENLIGHTEN 1 data has revealed that LYR-210 demonstrated improvement over control in symptomatic endpoints in the CRS patient cohort with nasal polyps, which we believe reinforces the therapeutic potential of our product candidates.”

Dr. Palasis continued, “While we intend to remain opportunistic about strategic options, our primary focus remains on the two ongoing ENLIGHTEN Phase 3 trials evaluating LYR-210 in CRS patients with and without nasal polyps: the ENLIGHTEN 1 52-week extension study with results expected in Q4 2024 and the ENLIGHTEN 2 pivotal trial with enrollment on track and results expected in the first half of 2025. We plan to be pragmatic and data-driven as we determine our path forward for CRS patients, investors, and other stakeholders.”

Highlights from May 2024 ENLIGHTEN 1 Pivotal Results and Subsequent Cost-cutting Measures

• On May 6, Lyra announced topline results from the Phase 3 ENLIGHTEN 1 trial showing that LYR-210 did not meet its primary endpoint of statistically significant improvement compared to sham control in the composite score of the three cardinal symptoms (3CS) of CRS (nasal obstruction, nasal discharge, facial pain/pressure) at 24 weeks. LYR-210 was generally well tolerated, with no product-related serious adverse events. 
  
  
• Following the ENLIGHTEN 1 results disclosed in May, Lyra announced cost-cutting measures to preserve capital, including a reduction in force of approximately 75% of its workforce in addition to other measures to reduce costs and streamline operations. In connection with the reduction in force, which impacted 87 employees, Lyra stopped manufacturing and commercialization efforts and is seeking to sublease its three leaseholds to significantly reduce the Company’s operating costs. Furthermore, Lyra paused development efforts for LYR-220 in an effort to focus on the ongoing ENLIGHTEN Phase 3 program evaluating LYR-210.
  

Additional Analysis from ENLIGHTEN 1 for CRS Patient Subgroup with Nasal Polyps

• Further analysis of the ENLIGHTEN 1 data shows that LYR-210 demonstrated a positive effect compared to sham control in 3CS and nasal congestion scores at 24 weeks in the CRS patient subgroup with nasal polyps.
  • Treatment with LYR-210 resulted in a mean (standard error; SE) improvement in the 3CS score of 3.21 (0.436) points, compared to 0.96 (0.619) points in sham control for a difference of 2.25 points (p-value 0.0058) in the CRS patient subgroup with nasal polyps. This improvement was demonstrated despite the inclusion of only grade 1 nasal polyps in the study and without a threshold for nasal congestion score.  
  • For patients with nasal congestion score equal to or greater than 2 (that is moderate to severe symptom) at baseline in the CRS patient subgroup with nasal polyps, treatment with LYR-210 resulted in a mean (SE) improvement in the 3CS score of 3.69 (0.470) points, compared to 0.75 (0.685) points in sham control for a difference of 2.94 points (p-value 0.0017).
  • Treatment with LYR-210 resulted in a mean (SE) improvement in the nasal congestion score of 1.20 (0.159) points, compared to 0.42 (0.243) points in sham control for a difference of 0.73 points (p-value 0.0216) in the CRS patient subgroup with nasal polyps and nasal congestion score equal to or greater than 2 at baseline.

Milestones for Ongoing ENLIGHTEN Pivotal Program of LYR-210 in CRS

• Enrollment in ENLIGHTEN 2, the second pivotal Phase 3 trial of LYR-210 in CRS, is ongoing; enrollment completion is expected in the second half of 2024.
  
  
• Topline results from ENLIGHTEN 2 are expected in the first half of 2025.
  
  
• Results from the ENLIGHTEN 1 52-week extension study are expected in Q4 2024.
  

Second Quarter 2024 Financial Highlights

Cash, cash equivalents and short-term investments as of June 30, 2024 were $67.5 million, compared with $102.8 million at December 31, 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 2026. Please see our Quarterly Report filed on Form 10-Q for the three and six months ended June 30, 2024 for further information regarding our cash runway guidance and other financial results.

Research and development expenses for the quarter ended June 30, 2024 were $13.3 million, an increase of $2.5 million compared to $10.8 million for the same period in 2023.

The increase in research and development expenses for the three months ended June 30, 2024 was primarily attributable to an increase of $1.7 million in allocated and support costs for shared activities within the organization driven by headcount allocation and rent increases which occurred prior to the reduction in force, an increase of $0.5 million in professional and consulting fees as we moved good manufacturing practices (“GMP”), manufacturing in house prior to the reduction in force and increased clinical and product manufacturing costs of $0.9 million as we continued to progress on our clinical trials and internal manufacturing efforts prior to the reduction in force. These costs were offset by $0.8 million in headcount related costs period over period due to the recent restructuring.

General and administrative expenses for the quarter ended June 30, 2024 were $5.1 million, an increase of $0.6 million compared to $4.5 million for the same period in 2023.

The increase in general and administrative expenses for the three months ended June 30, 2024 was primarily driven by an increase of $0.4 million for consulting costs, as well as an increase of $0.2 million in costs shared between the General & Administrative and Research & Development functions including headcount and rent. These costs were partially offset by a decrease in the amount of $0.1 million for employee related costs due to the recent restructuring.

The Company incurred impairment costs related to property and equipment of $1.9 million for the three months ended June 30, 2024 compared to $1.6 million for the same period in 2023.

The Company incurred impairment costs related to our right-of-use asset of $22.8 million for the three months ended June 30, 2024 and there were no such charges for the same period in 2023. 

The Company incurred a restructuring charge in the amount of $6.5 million primarily related to severance and retention costs for the three months ended June 30, 2024 and there were no such charges for the same period in 2023.

Net loss for the second quarter 2024 was $48.1 million compared to $15.6 million for the same period in 2023.  

About Lyra Therapeutics

Lyra Therapeutics, Inc. is a clinical-stage biotechnology company developing long-acting, anti-inflammatory sinonasal implants for the treatment of chronic rhinosinusitis (CRS). Lyra Therapeutics has two 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 bioabsorbable nasal implants designed to be administered in a simple, in-office procedure and are intended to deliver six months of continuous anti-inflammatory drug therapy (7500µg mometasone furoate) to the sinonasal passages for the treatment of CRS with a single administration. LYR-210, being evaluated in the ENLIGHTEN Phase 3 clinical program, has a smaller dimension and is intended for patients with standard anatomy, primarily patients who have not undergone ethmoid sinus surgery. LYR-220 is a larger implant designed for CRS patients whose nasal cavity is enlarged due to previous 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 statements are neither promises nor guarantees, but involve known and unknown risks, uncertainties and other important factors that may cause the Company's actual results, performance or achievements to be materially different from any future results, performance or achievements expressed or implied by the forward-looking statements, including, but not limited to, the following: any potential financial or strategic option we pursue in order to maximize shareholder value may not result in the identification of a suitable transaction, or if one is identified and pursued, may not be completed on attractive terms, or at all; our ability to sublease or assign our three leaseholds, which represent significant operating costs; our incurrence of significant losses since inception and expectation to incur significant additional losses for the foreseeable future; our recurring losses from operations raise substantial doubt regarding our ability to continue as a going concern; our need for significant additional funding in order to complete development of and obtain regulatory approval for our product candidates and commercialize our products, if approved; the failure of our ENLIGHTEN 1 Phase 3 trial to meet its primary endpoint has made it more difficult for the Company to raise capital; we could be forced to delay, reduce, or eliminate our product development programs or commercialization efforts; following the failure of our ENLIGHTEN 1 Phase 3 trial evaluating LYR-210 for the treatment of CRS to meet its primary endpoint, which was announced in May 2024, there is significant uncertainty about the Company’s ability to complete development of LYR-210 and our ability to obtain regulatory approval for LYR-210 is at least significantly delayed and may not be possible; our common stock may be delisted from The Nasdaq Global Market if we cannot regain compliance with Nasdaq’s continued listing requirements; our loss of key personnel significantly and adversely affects our ability to manufacture our product candidates, among other activities; we are no longer engaged in the manufacturing of our product candidates in-house; our business is highly dependent on the success of our most advanced product candidate, LYR-210; clinical trials required for our current product candidate and any future product candidates are expensive and time-consuming, their outcome is uncertain, and if our clinical trials do not meet safety or efficacy endpoints in these evaluations, or if we experience significant delays in these trials, our ability to commercialize our product candidates and our financial position will be impaired; any failure by a third party to conduct our pre-clinical or clinical trials according to good clinical practices and in a timely manner may delay or prevent our ability to seek or obtain regulatory approval for or commercialize our product candidates; even if LYR-210 receives marketing approval, it may fail to achieve market acceptance by physicians, patients, third-party payors or others in the medical community necessary for commercial success; if our collaborations are not successful, including with LianBio our product candidates may not reach their full market potential; our ability to manage our obligations under our license and other strategic agreements may divert management time and our limited resources, causing delays or disruptions to our business; our operating activities may be restricted by certain covenants in our license and strategic agreements, which could limit our development and commercial opportunities; failure to obtain marketing approval in international jurisdictions would prevent our products from being marketed in such jurisdictions; developments by competitors may render our products or technologies obsolete or non-competitive or may reduce the size of our markets; the successful commercialization of our product candidates will depend in part on the extent to which governmental authorities and health insurers establish coverage, adequate reimbursement levels and pricing policies; failure to obtain or maintain coverage and adequate reimbursement for our product candidates, if approved, could limit our ability to market those products and decrease our ability to generate revenue; if we are unable to obtain, maintain, or adequately protect our intellectual property rights, we may not be able to compete effectively in our market; the impact of international terrorism, political unrest and wars on our business; and the impact of other events such as the COVID-19 pandemic may adversely impact our business and operations, including our clinical trials. These and other important factors discussed under the caption "Risk Factors" in the Company's Quarterly Report on Form 10-Q filed with the SEC on August 14, 2024 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.
