-- Phase 3 Results from ENLIGHTEN 1 Trial of LYR-210 in Chronic Rhinosinusitis (CRS) Expected in May --

WATERTOWN, Mass., April 30, 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 first quarter ended March 31, 2024 and provided a corporate update.  

“With results imminent for our ENLIGHTEN 1 pivotal Phase 3 study of LYR-210 in CRS, we are laser-focused on delivering the topline data in May,” said Maria Palasis, Ph.D., President and CEO of Lyra Therapeutics. “We believe that LYR-210 has the potential to revolutionize the treatment of CRS by delivering a six-month therapy designed to provide long-acting relief that addresses the widespread need to overcome current treatment limitations faced by millions of patients.”

Lyra Therapeutics is developing LYR-210 and LYR-220, its two product candidates in late-stage development for the treatment of CRS. LYR-210 and LYR-220 are bioabsorbable sinonasal implants designed to be administered in a simple, in-office procedure and are intended to deliver six months of continuous mometasone furoate drug therapy (7500µg MF) to the sinonasal passages for the treatment of CRS with a single administration. LYR-210 is intended for patients with standard anatomy, primarily those who have not undergone ethmoid sinus surgery. LYR-220, a larger implant, is designed for CRS patients whose nasal cavity is enlarged due to previous surgery. 

Clinical Program Highlights

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

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

The ENLIGHTEN program consists of two pivotal Phase 3 clinical trials, ENLIGHTEN 1 and ENLIGHTEN 2, 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 who have not had ethmoid sinus surgery, randomized 2:1 to either LYR-210 (7500µg mometasone furoate (MF)) or control over 24 weeks. The ENLIGHTEN 1 trial also includes an extension phase to further assess the safety and repeat use of LYR-210 through 52 weeks. The goal of the two pivotal trials is to support a New Drug Application to the U.S. Food and Drug Administration (FDA) for LYR-210.

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

• The Company plans to present additional secondary endpoint data from the BEACON Phase 2 clinical trial of LYR-220 at the 2024 Combined Otolaryngology Spring Meetings (COSM) being held May 15-19, 2024 in Chicago, IL. The presentation, “Impact of LYR-220 on ethmoid opacification and CRS symptoms in the BEACON study,” is scheduled to take place on May 15, 2024 by Brent A. Senior, M.D., Nathaniel and Sheila Harris Distinguished Professor and Chief, Division of Rhinology, Allergy, and Endoscopic Skull Base Surgery in the Department of Otolaryngology/Head and Neck Surgery, UNC School of Medicine and Coordinating Investigator for the BEACON study. 
• An end-of-Phase 2 meeting for LYR-220 with the FDA is anticipated in the second half of 2024.

The Phase 2 BEACON trial was a randomized, controlled, parallel-group study intended to evaluate the safety and placement feasibility of the LYR-220 (7500µg mometasone furoate (MF)) implant, over a 28-week period, in symptomatic CRS patients who have had ethmoid sinus surgery. In September 2023, Lyra Therapeutics announced positive topline results from the BEACON Phase 2 clinical trial of LYR-220 in adult patients with CRS who have recurrent symptoms despite having had surgery.

First Quarter 2024 Financial Highlights

Cash, cash equivalents and short-term investments as of March 31, 2024 were $87.1 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 2025. Please see our Quarterly Report filed on Form 10-Q for the three months ended March 31, 2024 for further information regarding our cash runway guidance and other financial results.

Research and development expenses for the quarter ended March 31, 2024 were $18.2 million, an increase of $5.6 million compared to $12.6 million for the same period in 2023. The increase in research and development expenses for the three months ended March 31, 2024 was primarily attributable to increased headcount costs of $2.1 million, an increase of $2.1 million of allocated and support costs for shared activities within the organization, an increase of $1.0 million in professional and consulting fees and increased clinical costs of $0.4 million as we continued to advance our clinical trials.

General and administrative expenses for the quarter ended March 31, 2024 were $5.8 million, an increase of $0.7 million compared to $5.1 million for the same period in 2023. The increase in general and administrative expenses for the three months ended March 31, 2024 was primarily attributable to an increase of $0.7 million in headcount costs as we expand headcount within the organization, as well as $0.4 million of support costs for shared activities within the organization driven by headcount allocation and rent increases. These costs were partially offset by a decrease in other fees of $0.4 million due to prior year write-off of deferred financing costs.

Net loss for the first quarter 2024 was $22.5 million compared to $16.3 million for the same period in 2023.
